'''Duna''' is the fourth planet of the [[Kerbol]] star system. It is the Mars analog for Kerbal Space Program and is mostly red with polar icecaps. It has one natural satellite, the [[moon]] '''[[Ike]]'''. Due to Ike's size and proximity, Ike and Duna are tidally locked to each other.<br />
<br />
== Topography ==<br />
{|<br />
|<br />
[[File:Duna Topo ISA 3200x1600 compressed.png|thumb|right|A topographic map of Duna made with the ISA MapSat plugin]]<br />
Duna is a iron-rich planet which has greatly varying land altitude, the consequence of which is very difficult judgment of a safe landing position. Its mountainous ranges are a peril to landing craft, especially considering the thin atmosphere, where very little aerobraking can be done safely. It is important to slow one's ship down before coming into the atmosphere, to ensure a safe descent.<br />
<br />
There are several [[w:lunar maria|maria]] (large regions of dark soil) at exactly 0 meters altitude. These are excellent landing locations due to the their flatness and their low altitude, which allows for more aerobraking.<br />
<br />
Duna's poles are very expansive and are the result of a thin atmosphere. The central regions make a shape resembling Europe.<br />
<br />
Duna's surface contains [[list of easter eggs#Duna|anomolous features]], including a rock face similar to the one seen in [[w:Cydonia (region of Mars)#"Face on Mars"|early satellite images of Mars]].<br />
|}<br />
<br />
== Atmosphere ==<br />
{|<br />
|<br />
[[File:Atmosphere_kerbin_duna.png|thumb|right|A comparison of the atmospheres of Duna and Kerbin]]<br />
<br />
Duna's [[atmosphere]] begins at 41,446 m. It is only 20% as dense as [[Kerbin|Kerbin's]] at altitude 0 and is even less dense (relative to Kerbin) at higher altitudes.<br />
<br />
Like all atmospheres in the game, Duna's atmosphere fades exponentially with increasing altitude (with a scale height of 3000 m). In general, the atmospheric pressure on Duna at an altitude expressed in meters is:<ref>A [[LV-N Atomic Rocket Engine|nuclear engine]] has a specific impulse of 220 in 1 atm, 800 in vacuum, and the following at various Duna altitudes:<br />
{|<br />
| altitude (m) || 2 || 100 || 300 || 500 || 1460 || 2420 || 3000 || 4272 || 5000 || 10000<br />
|-<br />
| specific impulse || 684.1 || 687.8 || 695.1 || 701.8 || 728.7 || 748.2 || 757.3 || 772.1 || 778.1 || 795.9<br />
|}</ref><br />
<br />
: <math>p_d = 0.2\ e^{-altitude/3000}</math><br />
<br />
Parachutes work at lower efficiency than on Kerbin, making powered descent necessary when landing from orbit (unless your craft is a glider or just a pod with a parachute).<br />
<br />
An ascent to Low Duna Orbit from the surface typically requires around 1500 to 2000 m/s in Delta-V, leaving you in a orbit at 42km altitude traveling at roughly 950 m/s.<br />
<br />
The following table gives terminal velocities at different Duna altitudes. These are also the velocities at which a ship should travel for a fuel-optimal ascent from Duna, given the game's model of atmospheric drag.<ref>http://forum.kerbalspaceprogram.com/showthread.php/6664-Mini-challenge-max-altitude-with-this-supplied-spacecraft?p=100912&viewfull=1#post100912</ref><br />

== Orbital Statistics ==<br />
The [[w:geosynchronous_orbit|geosynchronous orbit]] of Duna is at an altitude of<br />
{{OrbitAltitude | period_s=65517.859375 | mass_kg=4.51548115036107e21 | radius_km=320 }} above Duna. The speed of the satellite is<br />
{{OrbitVelocity | period_s=65517.859375 | mass_kg=4.51548115036107e21 | radius_km=320 }} and it has an orbital period resonating with 1 Duna day (18.2 hours or 65517.859375 seconds). However, a long-term orbit at this point is not possible, as it will eventually intersect Ike's SOI.<br />
<br />
For a [[w:semi-synchronous_orbit|semi-synchronous orbit]] of ½ Duna day (9.025 hours or 32490 seconds) an orbit of<br />
{{OrbitAltitude | period_s=32758.9296875 | mass_kg=4.51548115036107e21 | radius_km=320 }} above Duna is needed with a velocity of<br />
{{OrbitVelocity | period_s=32758.9296875 | mass_kg=4.51548115036107e21 | radius_km=320 }}.<br />

== Trivia ==<br />
*On the surface of Duna, there is a large monument carved in the likeness of a Kerbal face, alluding to the infamous "Face of Mars" discovered in the Cydonia Mensae region of Mars during the 1970's. <br />
*Duna's name may be either a reference to its desert landscape or a shout-out to the Frank Herbert novel ''Dune.''<br />
*One anomalous feature on Duna is a small, pyramid-like hill emitting an SSTV signal. When decrypted, it shows a diagram-like image of three figures standing next to the hill itself, implying that Duna was once inhabited.<br />

'''Kerbin''' is the home planet of the [[Kerbal]]s, the location of the [[Kerbal Space Center|Space Center]], and the main focus of [[Kerbal Space Program]]. It is the [[w:Earth|Earth]] analog for the game. It has two [[moon]]s, named '''[[Mun]]''' and '''[[Minmus]]'''.<br />
<br />
Kerbin is the third planet in [[orbit]] around the star [[Kerbol]]. It is the third largest planet (after [[Jool]] and [[Eve]]) and the fourth largest celestial object around Kerbol (with [[Tylo]], a moon of Jool, being slightly larger).<br />
<br />
Reaching a stable orbit around Kerbin is one of the first milestones a player might achieve in the game. Achieving such an orbit with a fuel-optimal ascent<ref>A fuel-optimal ascent is one which (a) minimizes velocity losses to gravity and atmospheric drag and (b) launches eastward (toward the 90 degree heading) to gain 174.5 m/s of orbital velocity for free, thanks to Kerbin's rotation.</ref> requires a delta-V of ≈4380 m/s, the second largest of all celestial bodies with a solid surface after [[Eve]].<ref>[http://i.imgur.com/CEZS1.png Kerbin Delta-V Chart]</ref> For many interplanetary missions, this represents over half of the flight's total delta-V requirement. (This is also true of Earth-based interplanetary spaceflights, leading one observer to remark that "If you can get your ship into orbit, you're halfway to anywhere."<ref>Robert Heinlein, quoted on page 194 of ''A Step Farther Out'' by Jerry Pournelle.</ref>)<br />
<br />
== Topography ==<br />
{|<br />
|<br />
[[File:Kerbin ISA Topo.png|right|thumb|Topographical image of Kerbin from 0.17.1]]<br />
Kerbin has a roughly equal distribution of surface liquid water and solid land, with polar icecaps and scattered deserts. There are mountains exceeding 3 km in height, with the tallest peak being at least 3750 m in altitude.<ref>http://kerbalspaceprogram.com/forum/index.php?topic=11388.msg176509#msg176509 {{broken link}}</ref><br />
<br />
Kerbin shows signs of having been impacted by an asteroid or comet. That is visible in the large crater in the western hemisphere. Prominent is the central peak, which is caused by the compression followed by the rebound of material in the center of the crater. '''Note: is as of v0.18'''<br />
<br />
'''Note:''' There has been a change in the appearance of Kerbin in version 0.18<ref>http://forum.kerbalspaceprogram.com/entry.php/247-A-Brave-New-World</ref>, and that has contributed to the topography. ''All information within this article and note is valid as of version '''0.17.1''','' ''Save for the thumbnail above, which is from '''0.18.'''''<br />

== Atmosphere ==<br />
<br />
<!-- SPECULATION: Kerbin has an atmosphere of unknown composition, though because Kerbin has plants and animals, it can be assumed there is O<sub>2</sub>, N<sub>2</sub>, and CO<sub>2</sub>. -->Kerbin's [[atmosphere]] contains oxygen and extends to roughly 69,078 meters. Its atmosphere becomes exponentially less dense as altitude increases (with a scale height of 5 km).<ref>{{forum link|threadID=16000|threadName=&#91;KGSS&#93; Examining Kerbin's atmosphere}}</ref> In general, the atmospheric pressure on Kerbin, at an altitude expressed in meters, is:<br />
<br />

<br />
The following table gives approximation of terminal velocities at different Kerbin altitudes. These are also the velocities at which a ship should travel for a fuel-optimal ascent from Kerbin, given the game's model of atmospheric drag (0.18.1).<ref>http://forum.kerbalspaceprogram.com/showthread.php/6664-Mini-challenge-max-altitude-with-this-supplied-spacecraft?p=100912&viewfull=1#post100912</ref><br />

'''Duna''' is the fourth planet of the [[Kerbol]] star system. It is the Mars analog for Kerbal Space Program and is mostly red with polar icecaps. It has one natural satellite, the [[moon]] '''[[Ike]]'''. Due to Ike's size and proximity, Ike and Duna are tidally locked to each other.<br />

[[File:Duna Topo ISA 3200x1600 compressed.png|thumb|right|A topographic map of Duna made with the ISA MapSat plugin]]<br />
Duna is a iron-rich planet which has greatly varying land altitude, the consequence of which is very difficult judgment of a safe landing position. Its mountainous ranges are a peril to landing craft, especially considering the thin atmosphere, where very little aerobraking can be done safely. It is important to slow one's ship down before coming into the atmosphere, to ensure a safe descent.<br />
<br />
There are several [[w:lunar maria|maria]] (large regions of dark soil) at exactly 0 meters altitude. These are excellent landing locations due to the their flatness and their low altitude, which allows for more aerobraking.<br />
<br />
Duna's poles are very expansive and are the result of a thin atmosphere. The central regions make a shape resembling Europe.<br />
<br />
Duna's surface contains [[list of easter eggs#Duna|anomolous features]], including a rock face similar to the one seen in [[w:Cydonia (region of Mars)#"Face on Mars"|early satellite images of Mars]].<br />

== Atmosphere ==<br />
{|<br />
|<br />
[[File:Atmosphere_kerbin_duna.png|thumb|right|A comparison of the atmospheres of Duna and Kerbin]]<br />
<br />
Duna's [[atmosphere]] begins at 41,446 m. It is only 20% as dense as [[Kerbin|Kerbin's]] at altitude 0 and is even less dense (relative to Kerbin) at higher altitudes.<br />
<br />
Like all atmospheres in the game, Duna's atmosphere fades exponentially with increasing altitude (with a scale height of 3000 m). In general, the atmospheric pressure on Duna at an altitude expressed in meters is:<ref>A [[LV-N Atomic Rocket Engine|nuclear engine]] has a specific impulse of 220 in 1 atm, 800 in vacuum, and the following at various Duna altitudes:<br />

|}</ref><br />
<br />
: <math>p_d = 0.2\ e^{-altitude/3000}</math><br />
<br />
Parachutes work at lower efficiency than on Kerbin, making powered descent necessary when landing from orbit (unless your craft is a glider or just a pod with a parachute).<br />
<br />
An ascent to Low Duna Orbit from the surface typically requires around 1500 to 2000 m/s in Delta-V, leaving you in a orbit at 42km altitude traveling at roughly 950 m/s.<br />
<br />
The following table gives terminal velocities at different Duna altitudes. These are also the velocities at which a ship should travel for a fuel-optimal ascent from Duna, given the game's model of atmospheric drag.<ref>http://forum.kerbalspaceprogram.com/showthread.php/6664-Mini-challenge-max-altitude-with-this-supplied-spacecraft?p=100912&viewfull=1#post100912</ref><br />

<div>I do not agree with renaming the Mun to "Mün" as done by [[User:Eduardog3000]]. The moon is still labeled "Mun" in game and unless that changes, I do not see a need to have it labeled Mün ingame. I am aware there is confusion regarding this, which was strengthened by the new Title screen with the "Mün or bust" scene, but unless the "ü" makes it ingame, I suggest keeping "Mun" as the Wiki definition for now. --[[User:Senshi|Senshi]] ([[User talk:Senshi|talk]]) 09:23, 22 December 2012 (UTC)<br />
<br />
:I completely agree, this is just plain inaccurate. --[[User:Craigmt1|Craigmt1]] ([[User talk:Craigmt1|talk]]) 16:39, 22 December 2012 (UTC)</div>Craigmt1https://wiki.kerbalspaceprogram.com/index.php?title=Tutorial:How_to_get_to_Duna&diff=9946Tutorial:How to get to Duna2012-12-22T16:37:16Z<p>Craigmt1: </p>
<hr />
<div>[[File:Duna_map.png|thumb|225px|right|Duna. If you don't see this at some point during the tutorial, you've probably done it incorrectly.]]<br />
<br />
<br />
== Traveling to Duna ==<br />
[[Duna]] is [[Kerbin]]'s second closest neighbor. After a successful landing on Eve, it is likely your next logical step. It perhaps the ideal planet for interplanetary voyages for several reasons:<br />
<br />
# Its close proximity to [[Kerbin]].<br />
# Its small size and gravity well (comparable to The [[Mun]]).<br />
# Its atmospheric composition is thick enough to support aerobraking, yet also thin enough to permit an ascent back to orbit.<br />
# Possessing [[moon]] similar to Kerbin's, [[Ike]], in addition to several mysterious Easter Egg locations.<br />
<br />
With a little bit of luck, skill, and determination, you can successfully land on Duna and return to Kerbin, all in one ship, with ease.<br />
<br />
===Specifications===<br />
*'''Length:''' 1-3 hours<br />
*'''Difficulty:''' Moderate/Hard<br />
*'''For version:''' .17<br />
*'''Recommended Delta-V:''' ~7760 m/s<br />
**~4700 m/s to orbit around Kerbin<br />
**~1060 m/s for interplanetary transfer<br />
**~1500 m/s for ascent to orbit.<br />
**~500 m/s for return to Kerbin<br />
<br />
Additionally, you will need a good understanding of orbital mechanics (see [[Tutorials]] section), angles, and a lot of patience.<br />
<br />
==Steps==<br />
===Step 1 - Build Your Rocket===<br />
[[File:DunaRocket.jpg | thumb | right | An extremely barebones, lightweight interplanetary rocket. Despite having no middle stage it can reach Duna, and return to Kerbin with a little piloting skill.]]<br />
To perform a successful landing on Duna you will need a large rocket. Unless you are planning to deploy a spaceplane in the Dunan atmosphere (a perfectly viable option), you will need something resembling a highly beefed-up Mun Rocket.<br />
<br />
==== Upper Stage ====<br />
<br />
Balancing this stage is tricky. Largely similar to a [[Mun]] lander, with several key differences:<br />
<br />
#With proper parachute rigging, it will require little/no thrust for a landing (though save at least one parachute for Kerbin!)<br />
#For a return to Kerbin, you MUST touch down with at least 1 large fuel tank and an engine with high specific impulse intact.<br />
<br />
The best way to describe something that can get off of Duna, is a ship somewhere between one that can take off from the Mun, and one that can take off from Kerbin. You will need at least 2000ms Delta-V for the orbit and return, you can test this by seeing if your lander is **almost** capable of reaching Kerbin orbit by itself.<br />
<br />
==== Middle Stage ====<br />
This is the stage that will be doing a lot of the work. It must be capable of getting from Kerbin to Duna, and positioning your lander craft for the terminal descent. It must carry enough fuel for the DeltaV you will need to successfully pull this off.<br />
<br />
==== Lower Stage ====<br />
<br />
This stage should take you at least into Kerbin's orbit if you hope to reach Duna. It will require several large thrusters to lift the interplanetary vehicle itself into orbit, probably assisted by some SRBs. For reference, it should be about 1.5x bigger than what you would need for a 1 way trip to Eve.<br />
<br />
===Step 2 - Planetary Alignment===<br />
<br />
While not absolutely essential, the easiest and fastest way to reach Duna from Kerbin is ensuring that they are properly aligned. Otherwise, you may spend a lot of time (possibly years) and fuel drifting until they happen to match up.<br />
<br />
To do so, check your map and make sure that Duna is '''ahead of''' Kerbin in its orbit around [[Kerbol]].<br />
<br />
Look at it like a clock, if Kerbin is at 3 o'clock relative to the Sun, Duna should be at 1:30. Warp until they are in this position relative to each other.<br />
<br />
Alternatively, you can visit [http://ksp.olex.biz/ The Interplanetary Guide and Calculator] to calculate your own path.<br />
<br />
===Step 3 - Launch to Kerbin Orbit===<br />
<br />
Take off as usual (see [[Tutorials]] for how to achieve orbit), only tilt your craft heading '''east''' instead of the usual west. Unless you've done your own calculations, try to aim for a circular equatorial orbit spinning counter-clockwise at around 120,000 meters.<br />
<br />
===Step 4 - Fly from Kerbin to Duna===<br />
<br />
If have successfully reached your desired orbit around Kerbin, begin your high-velocity burn. Keep an eye on your map, wait until you are at about 5 o'clock around Kerbin (150 degrees), and get your velocity up to approximately 3020 m/s.<br />
<br />
It's really important to watch the map while you are accelerating. As you accelerate your Kerbolar orbital path should move to intersect Duna's. If all goes well, there should be a brief moment where you are captured by Duna's gravity well right around the target velocity. Immediately cut your thrust. If you overshoot, just turn the craft around and do a slight retro burn until you are caught again.<br />
<br />
This journey should take 70-120 days. While you are traveling around Kerbol, consider tweaking your trajectory until your periapsis around Duna is at the equator, and lower than 100km.<br />
<br />
===Step 5 - Arriving at Duna===<br />
<br />
When you enter Duna's sphere of influence you will always be traveling at escape velocity. Begin firing retro until you are in some kind of orbit, after you are caught it doesn't matter how far out you are.<br />
<br />
Assuming that you are trying to save fuel we are going to be doing an aerobrake here. As shown on the [[Duna#Atmosphere | information page]], Duna's atmosphere begins around 40km, so we are going for a periapsis lower than that. A periapsis of 15,000 meters above the surface will aerobrake you into orbit around Duna. Putting it slightly under 10,000 meters should be enough for a landing.<br />
<br />
If you are not planning on landing, being a forward burn at the apoapsis (once it has reached the desired altitude) to circularize your orbit.<br />
<br />
===Step 6 - Land on Duna===<br />
<br />
Adjust your orbital path to where you would like to land, and continue aerobraking to bleed off that extra velocity. Eventually you will be caught on a terminal descent through the atmosphere. Note that Duna's atmosphere is thinner and smaller, and so is your margin of error. Deploy your chutes around the 5k mark, and lower whatever landing gear you brought with you and fire retrorockets if the chutes aren't slowing you down enough. Ultimately we're going for typically touchdown speed (6-12m/s). Avoid tipping over at all costs, unless you plan on staying.<br />
<br />
Congratulations! You've landed on another planet! Walk around, feel the cool, toxic breeze of an afternoon on Duna!<br />
<br />
===Step 7 - Back to Orbit===<br />
<br />
Make sure Duna and Kerbin are in the proper alignment. This time, Duna should be at 3 o'clock with respect to Kerbol, and Kerbin itself should be at roughly 5:30. Warp until they are in alignment, do not take off until this has been achieved.<br />
<br />
While not nearly as difficult as ascending from Kerbin, you are still negotiating a decent-sized gravity well and an atmosphere. Our goal is to conserve as much fuel for the interplanetary burn as possible. Try to aim for a circular orbit, roughly 70km altitude, around Duna's equator.<br />
<br />
===Step 8 - Fly from Duna to Kerbin===<br />
<br />
Thankfully, this step requires less than half as much Delta-V as the trip from Kerbin to Duna. When your orbit is at 10 o'clock around Duna (-120 degrees), begin your burn. Our final velocity is going to be somewhere around 1500 m/s.<br />
<br />
When you are captured by Kerbin, tweak your approach as much as you can in advance, we're running on a tight fuel budget here and the sooner you make adjustments the less fuel you will need. If you can get your periapsis within 50km of Kerbin, you will not need to burn for the rest of the trip.<br />
<br />
===Step 9 - Landing back on Kerbin===<br />
<br />
Once you are back in Kerbin's SOI, make whatever changes to your approach you want to assuming you still have fuel. Keep your periapsis somewhere below 50km, keep it shallow though for a safe descent.<br />
<br />
Jettison your lander stage and go in with just the command module. Hopefully you've saved a parachute or two!<br />
<br />
Congratulations! Once you've succeeded at a round trip to Duna, anything is possible.<br />

== Duna Gravity borked. ==<br />
<br />
I'm no mathemetician, but if the gravity for other bodies such as Mun (6.51e10 m3/s2) and Gilly (8.289e6 m3/s2) have exponents on them, I think that the listing for Duna's 'gravitational parameter' (Gravitational parameter 301.321 m3/s2) isn't what it should be.<br />
<br />
Someone, throw some math at that and fix it :P<br />

== RoboJeb Picture Crushing ==<br />
<br />
Just wondering, what is the point in this? Does not the wiki engine already scale images as needed? Isn't this just making it harder for people to see the the highest resolution version? It is also a flawed theory that is saves space, as the original larger version is still saved, so it just takes up extra space. [[User:Thecoshman|Thecoshman]] ([[User talk:Thecoshman|talk]]) 09:18, 14 October 2012 (UTC)<br />
<br />
:I was referring to thumbnails people upload, which is redundant and a waste of space (as both the original AND the resized one are kept, while the wiki can have a higher-resolution version that can be used as a reference elsewhere, and the thumbnail. Plus, if a part is updated, we'd have to upload the original pic, open photoshop/GIMP, create the thumbnail, and then upload that. That workflow doesn't make any sense whatsoever. It's just easier to use the wiki. Plus, what if we resize the thumbnail size for an infobox? Instead of letting the wiki do it for us, we'd have to reupload all the thumbnails.<br />
<br />
:As for RoboJeb, he re-compresses badly-compressed PNGs and reuploads them if they need it. Helps save on bandwidth, particularly with very large images. - [[User:N3X15|<span class="squad">N3X15</span>]] <sup class="plainlinks">([[Special:Contribs/N3X15|C]] &middot; [[User_talk:N3X15|T]] &middot; [{{fullurl:User:N3X15/Sig|action=edit}} E])</sup> 09:35, 14 October 2012 (UTC)<br />
<br />
<br />
::But doesn't the wiki engine already allow users to upload a large image, and resize it as needed for things like thumb nails? Or does that only send the full size image and tell the browser to scale it down? I guess I hadn't really thought about how much bandwidth could be used up by larger images.<br />
<br />
::I wasn't really complaining about this, I was just curious was all. Thanks [[User:Thecoshman|Thecoshman]] ([[User talk:Thecoshman|talk]]) 10:02, 14 October 2012 (UTC)<br />
::: I was talking about people uploading thumbnails instead of thumbnailing them with the wiki.<br />
:::* We don't have the source image, so we can't resize it meaningfully in the future; We'd have to reupload it.<br />
:::* If the source image ''does'' exist on the wiki as well, we'd have to update both the thumbnail and the source image if a subject in the image changes, which is more work.<br />
:::* The wiki already generates thumbnails, so it doesn't make any sense to upload our own thumbnails.<br />
::: As for RoboJeb: By compression, I mean the PNG compression algorithm and company. Some programs don't compress images very well, and RoboJeb redoes it so the compression ratio is better. -- [[User:N3X15|<span class="squad">N3X15</span>]] <sup class="plainlinks">([[Special:Contribs/N3X15|C]] &middot; [[User_talk:N3X15|T]] &middot; [{{fullurl:User:N3X15/Sig|action=edit}} E])</sup> 10:10, 14 October 2012 (UTC)<br />

== Extension for formatting numbers ==<br />
<br />
Could you install the [http://www.mediawiki.org/wiki/Extension:FormatNum FormatNum extension]? (And can you remind me where wiki-related requests are supposed to go?

== New bot functionality ==<br />
<br />
I was wondering if you could look at adding some sort of talk page archiving bot. I know that wikipedia has something like this, it will monitor sections of talk pages, and if they get no replies for while, moves it to a archive page. The helps keep the main talk page focused, whilst saves the discussions. I think it would be really nice if it could manage a table of archived sections so that it is easier to see what previous talks their have been. Maybe if people could then go to the archived talk, add a new topic, and the bot will move it back to the main talk page, or they can just start a new section if it works better for them. I know that at the moment it's only really main page's talk page where this is starting to get an issue, but it can't hurt to start to get such a feature in the works. [[User:Thecoshman|Thecoshman]] ([[User talk:Thecoshman|talk]]) 08:10, 18 October 2012 (UTC)<br />

[http://kspwiki.nexisonline.net/wiki/Kerbol this] into [http://kspwiki.nexisonline.net/wiki/Kerbol/pl this]. I'm gonna get karolus10 (he's a mod on forums) to check it later for bugs, but just wanted to know what should I do to get Polish/Polski language versions to show up in "languages" in the left side menu?<br />
<br />
Also - how do I edit the language in the right-side object specification grey-box? You know, the mass, radious, etc?<br />
: Well, first, we need a [[Main Page/pl]] so there's a starting point for translators. Once that's done, I'll add it to the sidebar. <br />
: As for the templates, add {{tlx|lang|2=en=English version|3=pl=Polish version|4=(other languages, if they're present)}} to the parts needing translation. If it's becoming a nightmare, you may want to make a {{tlx|Dictionary/Phrase}} with the {{tlx|lang}} template as content. -- [[User:N3X15|<span class="squad">N3X15</span>]] <sup class="plainlinks">([[Special:Contribs/N3X15|C]] &middot; [[User_talk:N3X15|T]] &middot; [{{fullurl:User:N3X15/Sig|action=edit}} E])</sup> 02:33, 1 November 2012 (UTC)<br />

== Dwarf Planets ==<br />
<br />
For the purpose of organization, I've been thinking about breaking off some of the smaller planets into a separate category because I imagine that as more bodies are added it's going to be harder to organize them and keep them all in one place. What are your thoughts on this, and what do you think the cutoff for dwarf planets should be? --[[User:Craigmt1|Craigmt1]] ([[User talk:Craigmt1|talk]]) 00:40, 22 December 2012 (UTC)</div>Craigmt1https://wiki.kerbalspaceprogram.com/index.php?title=Category_talk:Dwarf_Planets&diff=9925Category talk:Dwarf Planets2012-12-22T00:37:33Z<p>Craigmt1: </p>

<div>== Defining a Dwarf Planet in KSP ==<br />
<br />
We obviously can't go by the IAU definition, there are no objects to clear, there is no real gravity having an effect on anything.<br />
<br />
So I propose a definition more relevant to KSP:<br />
<br />
'''A planet that is smaller than the average moon size (212 km) can be considered a dwarf planet.'''<br />
<br />
At the time of this writing, that includes two: Dres and Eeloo. Since it just so happens that these are also the two newest planets, we can likely expect to see more. Therefore, we should begin making the distinction sooner rather than later.<br />
Thoughts?<br />
<br />
<br />
:I am going to assume that you mean 212km in radius right? Maybe locking it at a nice even number of 225 or something (I like esthetically pleasing numbers)--[[User:Azivegu|Azivegu]] ([[User talk:Azivegu|talk]]) 21:26, 21 December 2012 (UTC)<br />
<br />
:It is difficult to make a failsafe criteria, as there's no way of knowing what the devs might put in next. In principle I like this idea, though I'd suggest picking a "straight" number as a limiter (e..g 200 or 250km equatorial ). There always will be discussion about this and "borderline cases" anyway, so better make it an easy number. Another - preferred by me - alternative would be to simply drop the term "dwarf planet" altogether, as it doesn't serve a particular purpose anyway. For the scope of this game, these bodies are planets. Off topic: Please sign your posts on Talk pages in the future. This helps identifying who contributed what part to the discussion, which becomes more important once several users attend the same topic. This can be done easily by writing <nowiki>~~~~</nowiki> .

<br />
:I do agree with you, and unless somebody feels really strongly about Moho qualifying as a planet I think we should set it at 250. I just would like to add the distinction (however redundant it may be) to add a bit of character to some of the smaller planets, and to avoid future clutter. I imagine that at some point in the near future, we are going to have a lot of planets on our hands that we'll have to squeeze into the CoolNav bar and the Celestial bodies tab below, so I feel it's better to draw some sort of line now rather than later.--[[User:Craigmt1|Craigmt1]] ([[User talk:Craigmt1|talk]]) 00:37, 22 December 2012 (UTC)</div>Craigmt1https://wiki.kerbalspaceprogram.com/index.php?title=Category:Moons&diff=9915Category:Moons2012-12-21T17:13:13Z<p>Craigmt1: </p>

Dres is a [http://en.wikipedia.org/wiki/Planet Planet] released in version 0.18. It is located between Duna and Jool, in a somewhat eccentric and inclined orbit. It is considered to be the [http://en.wikipedia.org/wiki/Ceres_(dwarf_planet) Ceres] analog of the Kerbolar system. The surface of Dres is pale white and very rocky and uneven, similar to the surface of the [[Mun]]. Unlike the [[Mun]], there are large patches of what appear to be ice.<br />
<br />
<br />
== Geography ==<br />
The surface of Dres is similar to that of [[Mun|Mün]] in a surface covered in regolith rubble. One notable feature is a several kilometers deep canyon.<br />

==Why Dres is a Planet==<br />
According to the [http://en.wikipedia.org/wiki/IAU_definition_of_planet IAU definition of a planet],<br />
<br />
<i>A planet is a celestial body which:<br />
<br />
1. Is in orbit around the Sun,<br />
<br />
2. Has sufficient mass to assume hydrostatic equilibrium (a nearly round shape), and<br />
<br />
3. Has "cleared the neighbourhood" around its orbit.</i><br />
<br />
Dres, a celestial body, orbits kerbol, has a nearly spherical shape, and has cleared it's neighborhood of debris.<br />

It is the seventh planet from [[Kerbol]], though it occasionally intersects [[Jool]]'s orbit, passing in front of it. It is also locked in a 3:2 resonance with Jool.<br />
<br />
Eeoloo's size and mass are very roughly comparable to that of the [[Mün]], as is its lack of atmosphere. The body is most likely an analogue of the ice moon [http://en.wikipedia.org/wiki/Europa_(moon) Europa] or the dwarf planet [http://en.wikipedia.org/wiki/Pluto_(dwarf_planet) Pluto].<br />
<br />
== Topography ==<br />
The surface of Eeloo is relatively smooth and covered in ice, with deep canyons exposing the surface below. It is unclear if there are any peaks above 2 km high.<br />
<br />
== Orbits ==<br />
A synchronous orbit is possible, at an altitude of ~683.9 km.<br />

<div>== Defining a Dwarf Planet in KSP ==<br />
<br />
We obviously can't go by the IAU definition, there are no objects to clear, there is no real gravity having an effect on anything.<br />
<br />
So I propose a definition more relevant to KSP:<br />
<br />
'''A planet that is smaller than the average moon size (212 km) can be considered a dwarf planet.'''<br />
<br />
At the time of this writing, that includes two: Dres and Eeloo. Since it just so happens that these are also the two newest planets, we can likely expect to see more. Therefore, we should begin making the distinction sooner rather than later.<br />

'''Jool''' is a [[w:Gas giant|gas giant]] and the sixth planet of the [[Kerbol]]ar star system. It is the 6th planet from [[Kerbol]], making it one of the harder planets to reach. It is one of the most appealing targets for missions, however, because of its large and complex system of five moons: '''[[Laythe]]''', '''[[Vall]]''', '''[[Tylo]]''', '''[[Bop]]''', and '''[[Pol]]'''. Orbits well-aligned with the orbital plane, and many intersections with moon orbits can easily be captured by a couple moons with little to no ΔV before having to correct your orbit.<br />
<br />
== Atmosphere ==<br />
{|<br />
|<br />
[[File:JoolAtmosphere.png|thumb|right|Aerobraking in Jool's atmosphere.]]<br />
<br />
Although Jool has a radius ten times greater than [[Kerbin]], its [[atmosphere]] begins just twice as high (138.2 km). It is extremely dense, well suited for aerobraking from a high-speed interplanetary intercept. Orbiting just outside the atmosphere will give you a period of 94.7437 minutes, and a speed of 6,785 m/s. You typically do not need to go lower than 60 km to aerobrake.<br />
<br />
In general, the atmospheric pressure on Jool at an altitude expressed in meters is:<br />
: <math>p_j = 15\ e^{-altitude/9000}</math><br />
<br />
[[File:Kerbal_landing_on_jool.png|thumb|right|The effects of landing on Jool's "surface" as a Kerbonaut]]<br />
Closer to the surface, the physics of the game start to break down. Due to its extremely thick atmosphere, terminal velocity is so low that lighter spacecraft will not even need parachutes or retrorockets. It is not impossible to land on its solid surface, though spacecraft are inevitably and invariably devoured by the [[Kraken]]. If a Kerbonaut is put on EVA he will not be destroyed, making one-way sacrificial landings possible. However, as seen near the end of [http://www.youtube.com/watch?v=Kkeb5-u3-lY this video], the Kerbonaut will start to glitch out and shake uncontrollably. This only happens if you're on time warp 4. The game will later glitch and cut to a black screen with the altimeter going through numbers rapidly. Unless you restart the game, Kerbin's atmosphere will be missing.<br />
|}<br />
<br />
== Natural Satellites ==<br />
{|<br />
|<br />
[[File:JoolLaythe.png|thumb|right|The ocean moon [[Laythe]], about to transit Jool.]]<br />
<br />
Jool has five natural satellites:<br />
* The ocean moon [[Laythe]], currently the only moon possessing an atmosphere, is the closest to Jool and second largest of its moons. Due to its high orbital velocity, it is somewhat challenging to reach. Next to [[Eve]], its size and composition make it the most similar celestial body to [[Kerbin]]<br />
* The ice moon [[Vall]], which is the third largest and second closest. Its orbital path and velocity sit almost exactly between Layth and Tylo.<br />
* The rocky moon [[Tylo]], similar to Kerbin's [[Mun]], although it has similar gravity to [[Kerbin]]. While having the largest SOI, making it easiest to encounter, achieving orbit and landing are exceptionally difficult due to it's large gravity well coupled with lack of atmosphere.<br />
* The captured asteroid [[Bop]], the smallest body orbiting Jool. Due to its distant, erratic orbit and low gravity, it is also challenging to reach.<br />
<br />
*In 0.18, a new moon was added, [[Pol]], named so after a Pollen grain which it resembles. A yellowish/greenish moon, rocky and uneven with tall spiky mountains. It orbits Jool beyond Bop and is around twice as large. An image can be found [http://i.imgur.com/SshEN.png here].<br />
<br />
[[Laythe]], [[Vall]], and [[Tylo]] are in a Laplace resonance, with orbital periods of 1:2:4 respectively. Despite the fact that the moons can easily eclipse both each other and Jool, they do not.<br />

<br />
== Trivia ==<br />
* Jool has roughly the same equatorial radius as the planets Earth and Venus.<br />
* The sunsets and sunrises on Jool are purple.<br />
<br />
* Like Io Europa and Ganymede , Jool moon have Laplace resonance 1:2:4<br />

== Style guide ==<br />
<br />
Can we adopt [http://en.wikipedia.org/wiki/Wikipedia:Manual_of_Style Wikipedia's manual of style] as our own? &mdash; [[User:Elembis|Elembis]] ([[User talk:Elembis|talk]]) 19:02, 2 October 2012 (UTC)<br />
: This makes sense to me, I would assume we want to aim for a quality wiki. That said, I would be careful with sticking to the 'rules' too strictly, after all we should aim to cater for a 'tounge in cheeck' approach, fitting in with the comedy style of the game it self. [[User:Thecoshman|Thecoshman]] ([[User talk:Thecoshman|talk]]) 19:31, 2 October 2012 (UTC)<br />
:: We do need a manual of style, but it needs to be something less formal. We don't need to be a scholarly source, we just need to have a consistent style. Stuff like links (<code><nowiki>[[IVA]]s</nowiki></code> instead of <code><nowiki>[[IVA|IVAs]]</nowiki></code>, which is enforced by RoboJeb already), tables, and other things that make it mildly easier to edit a page. -- [[User:N3X15|<span class="squad">N3X15</span>]] <sup class="plainlinks">([[Special:Contribs/N3X15|C]] &middot; [[User_talk:N3X15|T]] &middot; [{{fullurl:User:N3X15/Sig|action=edit}} E])</sup> 04:10, 12 October 2012 (UTC)<br />
::: wait... you prefer <nowiki>[[example]]s over [[example]]s</nowiki>? Oh lord! I think the first style looks ugly as sin because you end up with that one letter no part of the link, I much prefer the latter style. as for adopting a formal guide, I agree with you N3X15, as long as we have a consistent style, perhaps a page can be created where some of these guide lines can be added as they arise in very organic way? [[User:Thecoshman|Thecoshman]] ([[User talk:Thecoshman|talk]]) 08:41, 12 October 2012 (UTC)<br />
:::: ah, I did not realise that the pluralising 's' will be considered part of the link, so we can disregard my complaints about that. [[User:Thecoshman|Thecoshman]] ([[User talk:Thecoshman|talk]]) 15:17, 12 October 2012 (UTC)<br />
<br />
== Adding new namespaces ==<br />
<br />
This is something that will require admin attention. Would it be possible for the 'Tutorials' namespace to be properly added to the system. It would also be usefully if there was a namespace along the line of 'API' or 'DevDocs'. Instructions on how to do this can be found [http://www.mediawiki.org/wiki/Manual:Using_custom_namespaces here]. [[User:Thecoshman|Thecoshman]] ([[User talk:Thecoshman|talk]]) 10:37, 5 October 2012 (UTC)<br />
* Done. -- [[User:N3X15|N3X15]] ([[User talk:N3X15|talk]]) 09:36, 8 October 2012 (UTC)<br />
<br />
== English English or American English? ==<br />
<br />
I would assume that American English is the preferred English for this wiki. Though, I think it should be stated clearly so that we can avoid ping-pong edits between American and English English. If we get to vote in this matter, I would prefer English English, on account of being English, but not that fussed overall. [[User:Thecoshman|Thecoshman]] ([[User talk:Thecoshman|talk]]) 08:55, 8 October 2012 (UTC)<br />
* I don't see how theatre/theater, etc. would result in pingponging, as either are valid and aren't worth editing over. Best thing to do would be to leave rules instructing users not to bother editing minor dialect-specific things. As for measurements, we should be using metric anyway, as KSP deals with a lot of science (obviously). I'll (hopefully) start working on rules tomorrow. -- [[User:N3X15|N3X15]] ([[User talk:N3X15|talk]]) 09:43, 8 October 2012 (UTC)<br />
<br />
== Units of measurement for part masses and engine thrust ==<br />
<br />
At the moment, the game doesn't specify units of measure for part masses or engine thrusts. We should agree on what to show in the wiki. There has been '''[[User_talk:Elembis#Units_of_measure|some discussion]]''' on this, but I figured it'd be useful to get some more feedback and hopefully a consensus.<br />
<br />
A Wikipedia-style vote, with discussion at the end, seems appropriate. =) Please cast your vote by putting your signature (<nowiki>~~~~</nowiki>) in a list, and feel free to elaborate in comments at the ends of all the lists. =) &mdash; [[User:Elembis|Elembis]] ([[User talk:Elembis|talk]]) 04:32, 18 October 2012 (UTC)<br />

: It's not really as much a matter of opinion, and as much as I enjoy the debate, it's a matter of simple physics! :) --[[User:Jlmr|Jlmr]] ([[User talk:Jlmr|talk]]) 04:52, 18 October 2012 (UTC)<br />
: I'm starting to think that Elembis's premise 3 was wrong, and rocket parts/kerbals are in ''different'' mass units from the star/planets/moons. Given that we can't push planets around, this seems workable.<br />
:: Considering the game does not specify units, why are we even having this debate? If anything, there should just a page on [[units]] explaining that the game does not define units, but that they appear to be consistent with treating them in kg and N. And let's not forget, working in kg-N or Mg-N does not matter, it is just a different scale, though I would avoid using 'tonne' or 'ton' as it is a stupid term that has a bazillian interpretations. Never known of any cases where someone was wondering if you meant a UK Kg or a USA Kg. This also is some what relevant to my question above, are we aiming for UK English or US English. [[User:Thecoshman|Thecoshman]] ([[User talk:Thecoshman|talk]]) 07:58, 18 October 2012 (UTC)<br />
::: There are multiple reasons to define the units. Several include: the wiki already defined them as kg and N (not physically possible), giving modders formulas to standardize the physical properties of new parts, converting realworld spacecraft into KSP, and above all, making the physics work on paper, the game already uses m/s L/s and meters as units of measure so it is not had to figure out that the units of measure for parts is in 1000's of kg and 1000's of N. I am not sure we should use kg and N, as it will involve a bit of work converting all the in-game part descriptions from tonnes to kg and from kN to N and probably confuse people who are looking at the in-game units and the wiki. Regardless, let's stick with SI as it is the unit already defined in-game for fuel consumption and acceleration. --[[User:Jlmr|Jlmr]] ([[User talk:Jlmr|talk]]) 19:54, 18 October 2012 (UTC)<br />
<br />
'''Justification for t and kN (or 1000's kg and 1000's of N)''' This is a condensed version of all my arguments. --[[User:Jlmr|Jlmr]] ([[User talk:Jlmr|talk]]) 20:52, 18 October 2012 (UTC)<br />
<br />
*An official NIST/SI publication: http://physics.nist.gov/Pubs/SP330/sp330.pdf states that kilonewton (kN) is a valid SI unit to represent 1000 N and ton (t), while historically a non-SI unit, has been accepted for use in the SI system by [[w:CIPM|CIPM]] as a valid unit to represent 1000 kg for just over a century.<br />
<br />
*We already know that the game uses SI units. These '''are''' specifically labeled: meters for units of distance, meters/sec for acceleration, liters for fuel volume, and liters/sec for fuel consumption.<br />
<br />
*We know that the Mk1-2 Command Pod weighs 4 "units" from the in-game description. The command pod is roughly 2 m in height and 2 m in diameter. Calculating it's total volume gives us about 2.09 m3. Let's assume the capsule has 0.05 m (2 in) thick walls and subtract the interior void to get only the volume of the capsule walls. This gives us a volume of 1.80 m3. <br />
**Knowing the volume of the walls, we can calculate the density of the material making up the capsule, taking the 4 in-game units to mean kg, this comes out to be about 13.79 kg/m3. Unfortunately, is about 72.29 times less dense than water at room temperature and closer in density to most gasses! Perhaps Kerbals have discovered a super strong gas-like substance to make spaceships from? =)<br />
**However, if we take the 4 in-game units to mean metric tons, we get a density of around 13793.10 kg/m3, well within the range of the density of real building materials.<br />
<br />
*The wikipage on [[Kerbin]] states it has a surface gravity of 9.81 m/s2, roughly that of Earth.<br />
**Given this we can calculate the following. If measured in kilograms(kg), a "9 kg" Rockomax X200-16 Fuel Tank on Kerbin, having a surface gravity of 9.81 m/s2, would be roughly the size of a 48 oz coffee tin and only hold about 1.5 L of fuel. Unfortunately for our intrepid Kerbals, 1.5 L of fuel would not provide enough energy to lift a 9 kg payload through 75,000 m of atmosphere, much less a few hundred meters.<br />
**If measured in metric tons, a "9 t" (9,000 kg) Rockomax X200-16 Fuel Tank under the same gravity, being about 0.67 m tall and 2 m in diameter, gives a volume of 2104.87 L, more than enough to hold the advertised 1600 L of fuel. Only a rocket engine with a thrust around 100 kN (100,000 N), could have any chance of lifting the 9 t (9,000 kg) fuel tank.<br />
**Similarly, a substance weighing only 8 kg with a volume of 1,600 L has a density of 5 kg/m3, only about three times greater than the density of gaseous oxygen, and would not make an efficient fuel. Whereas, a fuel weighing 8 t with a volume of 1,600 L has a density of 5000 kg/m3, closer to a realistic rocket fuel.<br />
<br />
*On the wiki pages we could just as easily say 4,000 kg instead of 4 t. However, this takes up unnecessary space on the page.<br />
<br />
*I know it's only a mod, but MechJeb already uses kN and tons for it's calculations of mass and thrust... =)<br />

Eeloo is an upcoming [http://en.wikipedia.org/wiki/Dwarf_Planet Dwarf Planet] that is expected to be released in version 0.18.2 as a Christmas gift to the KSP community. It is the seventh planet from [[Kerbol]], though it occasionally intersects [[Jool]]'s orbit, passing in front of it. It is also locked in a 3:2 resonance with Jool. It is most likely an analogue of the ice moon [http://en.wikipedia.org/wiki/Europa_(moon) Europa].<br />
<br />
== Geography ==<br />
The surface of Eeloo is relatively smooth and covered in ice, with deep canyons exposing the surface below.<br />

With the introduction of new, smaller planets like Dres and Eeloo (and a potential third planet closer than Moho), I propose we add a subcategory for dwarf planets and establish the cutoff at 200,000 m radius.

Dres is a [http://en.wikipedia.org/wiki/Dwarf_Planet Dwarf Planet] released in version 0.18. It is located between Duna and Jool, in a somewhat eccentric and inclined orbit. It is considered to be the [http://en.wikipedia.org/wiki/Ceres_(dwarf_planet) Ceres] analog of the Kerbolar system. The surface of Dres is pale white and very rocky and uneven, similar to the surface of the [[Mun]]. Unlike the [[Mun]], there are large patches of what appear to be ice.<br />
<br />
<br />
== Geography ==<br />
The surface of Dres is similar to that of [[Mun|Mün]] in a surface covered in regolith rubble. One notable feature is a several kilometers deep canyon.<br />

'''Jool''' is a [[w:Gas giant|gas giant]] and the sixth planet of the [[Kerbol]]ar star system. As of .18, it is the most distant of the six planets and the hardest to reach. It is one of the most appealing targets for missions, however, because of its large and complex system of five moons: '''[[Laythe]]''', '''[[Vall]]''', '''[[Tylo]]''', '''[[Bop]]''', and '''[[Pol]]'''. Orbits well-aligned with the orbital plane, and many intersections with moon orbits can easily be captured by a couple moons with little to no ΔV before having to correct your orbit.<br />
<br />
== Atmosphere ==<br />
{|<br />
|<br />
[[File:JoolAtmosphere.png|thumb|right|Aerobraking in Jool's atmosphere.]]<br />
<br />
Although Jool has a radius ten times greater than [[Kerbin]], its [[atmosphere]] begins just twice as high (138.2 km). It is extremely dense, well suited for aerobraking from a high-speed interplanetary intercept. Orbiting just outside the atmosphere will give you a period of 94.7437 minutes, and a speed of 6,785 m/s. You typically do not need to go lower than 60 km to aerobrake.<br />
<br />
In general, the atmospheric pressure on Jool at an altitude expressed in meters is:<br />
: <math>p_j = 15\ e^{-altitude/9000}</math><br />
<br />
[[File:Kerbal_landing_on_jool.png|thumb|right|The effects of landing on Jool's "surface" as a Kerbonaut]]<br />
Closer to the surface, the physics of the game start to break down. Due to its extremely thick atmosphere, terminal velocity is so low that lighter spacecraft will not even need parachutes or retrorockets. It is not impossible to land on its solid surface, though spacecraft are inevitably and invariably devoured by the [[Kraken]]. If a Kerbonaut is put on EVA he will not be destroyed, making one-way sacrificial landings possible. However, as seen near the end of [http://www.youtube.com/watch?v=Kkeb5-u3-lY this video], the Kerbonaut will start to glitch out and shake uncontrollably. This only happens if you're on time warp 4. The game will later glitch and cut to a black screen with the altimeter going through numbers rapidly. Unless you restart the game, Kerbin's atmosphere will be missing.<br />

== Natural Satellites ==<br />
{|<br />
|<br />
[[File:JoolLaythe.png|thumb|right|The ocean moon [[Laythe]], about to transit Jool.]]<br />
<br />
Jool has five natural satellites:<br />
* The ocean moon [[Laythe]], currently the only moon possessing an atmosphere, is the closest to Jool and second largest of its moons. Due to its high orbital velocity, it is somewhat challenging to reach. Next to [[Eve]], its size and composition make it the most similar celestial body to [[Kerbin]]<br />
* The ice moon [[Vall]], which is the third largest and second closest. Its orbital path and velocity sit almost exactly between Layth and Tylo.<br />
* The rocky moon [[Tylo]], similar to Kerbin's [[Mun]], although it has similar gravity to [[Kerbin]]. While having the largest SOI, making it easiest to encounter, achieving orbit and landing are exceptionally difficult due to it's large gravity well coupled with lack of atmosphere.<br />
* The captured asteroid [[Bop]], the smallest body orbiting Jool. Due to its distant, erratic orbit and low gravity, it is also challenging to reach.<br />
<br />
*In 0.18, a new moon was added, Pol, named so after a Pollen grain which it resembles. A yellowish/greenish moon, rocky and uneven with tall spiky mountains. It orbits Jool beyond Bop and is around twice as large. An image can be found [http://i.imgur.com/SshEN.png here].<br />
<br />
Laythe, Vall, and Tylo are in a Laplace resonance, with orbital periods of 1:2:4 respectively. Despite the fact that the moons can easily eclipse both each other and Jool, they do not.<br />

'''Eve''' is the second [[planet]] from [[Kerbol]] and is the second largest body orbiting it. It is purple in appearance. It has one small moon, a captured asteroid called '''[[Gilly]]'''.<br />
<br />
Eve is the closest planet to [[Kerbin]] and the easiest to reach, requiring the least delta-v of any planet. Having a similar size to Kerbin gives it a large gravity well. It's thick atmosphere makes aerocaptures and landings easy, but also makes return missions nearly impossible.<br />

[[File:Eve_isa_mapsat.png|thumb|right|A topographic map of Eve made with the ISA MapSat plugin]]<br />
Eve has several oceans and large, flat continents with a few mountain peaks. There is a distinctly large crater in the western hemisphere. The surface looks like purple sand dunes. There are several large mountains with heights exceeding 10,000 meters (making them the only places where ascents to orbit are feasible).<br />

'''Eve''' is the second [[planet]] from [[Kerbol]] and is the second largest body orbiting it. It is purple in appearance. It has one small moon, a captured asteroid called '''[[Gilly]]'''.<br />
<br />
Eve is the closest planet to [[Kerbin]] and the easiest to reach, requiring the least delta-v of any planet. Having a similar size to Kerbin gives it a large gravity well. It's thick atmosphere makes aerocaptures and landings easy, but also makes return missions nearly impossible.<br />

'''Jool''' is a [[w:Gas giant|gas giant]] and the sixth planet of the [[Kerbol]]ar star system. It is the most distant of the six planets and the hardest to reach. It is one of the most appealing targets for missions, however, because of its large and complex system of five moons: '''[[Laythe]]''', '''[[Vall]]''', '''[[Tylo]]''', '''[[Bop]]''', and '''[[Pol]]'''. Orbits well-aligned with the orbital plane, and many intersections with moon orbits can easily be captured by a couple moons with little to no ΔV before having to correct your orbit.<br />
<br />
== Atmosphere ==<br />
{|<br />
|<br />
[[File:JoolAtmosphere.png|thumb|right|Aerobraking in Jool's atmosphere.]]<br />
<br />
Although Jool has a radius ten times greater than [[Kerbin]], its [[atmosphere]] begins just twice as high (138.2 km). It is extremely dense, well suited for aerobraking from a high-speed interplanetary intercept. Orbiting just outside the atmosphere will give you a period of 94.7437 minutes, and a speed of 6,785 m/s. You typically do not need to go lower than 60 km to aerobrake.<br />
<br />
In general, the atmospheric pressure on Jool at an altitude expressed in meters is:<br />
: <math>p_j = 15\ e^{-altitude/9000}</math><br />
<br />
[[File:Kerbal_landing_on_jool.png|thumb|right|The effects of landing on Jool's "surface" as a Kerbonaut]]<br />
Closer to the surface, the physics of the game start to break down. Due to its extremely thick atmosphere, terminal velocity is so low that lighter spacecraft will not even need parachutes or retrorockets. It is not impossible to land on its solid surface, though spacecraft are inevitably and invariably devoured by the [[Kraken]]. If a Kerbonaut is put on EVA he will not be destroyed, making one-way sacrificial landings possible. However, as seen near the end of [http://www.youtube.com/watch?v=Kkeb5-u3-lY this video], the Kerbonaut will start to glitch out and shake uncontrollably. This only happens if you're on time warp 4. The game will later glitch and cut to a black screen with the altimeter going through numbers rapidly. Unless you restart the game, Kerbin's atmosphere will be missing.<br />

== Natural Satellites ==<br />

|<br />
[[File:JoolLaythe.png|thumb|right|The ocean moon [[Laythe]], about to transit Jool.]]<br />
<br />
Jool has five natural satellites:<br />
* The ocean moon [[Laythe]], currently the only moon possessing an atmosphere, is the closest to Jool and second largest of its moons. Due to its high orbital velocity, it is somewhat challenging to reach. Next to [[Eve]], its size and composition make it the most similar celestial body to [[Kerbin]]<br />
* The ice moon [[Vall]], which is the third largest and second closest. Its orbital path and velocity sit almost exactly between Layth and Tylo.<br />
* The rocky moon [[Tylo]], similar to Kerbin's [[Mun]], although it has similar gravity to [[Kerbin]]. While having the largest SOI, making it easiest to encounter, achieving orbit and landing are exceptionally difficult due to it's large gravity well coupled with lack of atmosphere.<br />
* The captured asteroid [[Bop]], the smallest body orbiting Jool. Due to its distant, erratic orbit and low gravity, it is also challenging to reach.<br />
<br />
*In 0.18, a new moon was added, Pol, named so after a Pollen grain which it resembles. A yellowish/greenish moon, rocky and uneven with tall spiky mountains. It orbits Jool beyond Bop and is around twice as large. An image can be found [http://i.imgur.com/SshEN.png here].<br />
<br />
Laythe, Vall, and Tylo are in a Laplace resonance, with orbital periods of 1:2:4 respectively. Despite the fact that the moons can easily eclipse both each other and Jool, they do not.<br />

<hr />
<div>Ever wanted to launch a jet aircraft from the runway, and successfully deploy a payload into orbit? Well now you can!<br />
<br />
Advantages:<br />
At the height of launch, less drag and gravity means drastically smaller Delta-V requirements for the rocket. Therefore, it can be smaller, lighter, and carry a larger payload.<br />
<br />
Disadvantages:<br />
The aircraft must be capable of carrying the rocket off the runway to proper altitude and speed. A tradeoff must be made between either aircraft size or rocket weight.<br />
<br />
Design considerations:<br />
<br />
Your aircraft should be capable of reaching 15-20 km altitude, and traveling at a speed between 750-1000m/s at release.<br />
<br />
Realistically, the drop payload should be no more than 1 or 2 stages.<br />
<br />
Dropping the rocket without impacting the aircraft is difficult. If you are using strap-on jet engines, consider adding Sepratrons to blow them away at stage separation. Alternatively, you could house the rocket below the body of the aircraft at drop, or anchor it above the craft, adding winglets to allow a rapid climb.</div>Craigmt1https://wiki.kerbalspaceprogram.com/index.php?title=Tutorial:_Basic_Orbiting_(Technical)&diff=9608Tutorial: Basic Orbiting (Technical)2012-12-17T16:58:09Z<p>Craigmt1: /* Transfer Orbits */ What the hell is a "perikee"?

<div>{{Stub|tutorial|Needs some math tags and general cleanup. -- [[User:N3X15|N3X15]] ([[User talk:N3X15|talk]]) 08:46, 1 October 2012 (UTC)}}<br />
<br />
Getting into space is relatively easy, but staying there without drifting endlessly into space or falling back down to Kerbin can be challenging. This tutorial will teach you how to get into and remain in [[orbit]], how to adjust your orbit to be circular or elliptical, and how to adjust to a higher or lower orbit.<br />
<br />
The force acting on one of the masses m by the other two is: <br />
<br />
<math>\frac{GMm}{R^2} + \frac{Gmm}{4R^2}</math><br />
<br />
This acts as the centripetal force and hence <br />
<br />
<math>mR?^2\frac{GMm}{R^2}+\frac{Gmm}{4R^2} = mR?^2R^3*?^2 =\frac{G(4M+m)}{4 ?} = \frac{2? }{ T }</math><br />
<br />
and hence, <br />
<br />
T = 4 ? R ^ (3/2) / ?{ G [4 M + m]}<br />
<br />
== Stabilizing your orbit ==<br />
<br />
During each orbit, your craft will reach maximum altitude, called '''apoapsis''', and on the opposite side of the planet, it will reach minimum altitude, called '''periapsis'''. At both apoapsis and periapsis, your vertical speed will be zero. These points are the easiest points to make orbital corrections, because you can easily determine how fast to go when your vertical speed is zero. '''Note:''' The relative difference between your orbit's apoapsis and periapsis is called its '''eccentricity.''' Orbits that are exactly circular have zero eccentricity, and highly "flattened-out" orbits have eccentricity close to 1.<br />
<br />
There are a number of third-party calculators available which can crunch the numbers and tell you your eccentricity, as well as provide the speeds required to circularize your orbit at your current (or future) altitude. Whether you calculate your orbits by hand, or use a third party app, the general procedures are still the same and are given below:<br />
<br />
First, in order to get into a nice, round orbit, you need to determine how fast to go. The higher your orbit, the less gravity you'll feel from Kerbin, so the slower you'll need to go to be in a circular orbit. Consult the table below, or use a 3rd party table, to determine the proper speed for your altitude at apoapsis or periapsis. You'll probably want to watch your altimiter as you near one of the critical points, remember the altitude, look up the speed in the table, and make the correction on your next pass. If you want to "round out" your orbit from apoapsis, you need to speed up to avoid falling back down to periapsis. Point your craft in the exact direction of travel (use the green circular indicator on the gimbal to line up), and apply thrust until you've gained enough speed. To round out an orbit from periapsis, you need to slow down to avoid climbing back up to apoapsis. Point your craft in the opposite direction of travel (indicated on the gimbal by a green circle with an "X" through it), and apply thrust until you have slowed to the speed indicated by the table. You should then be in an orbit that is very close to circular! Depending on how eccentric your initial orbit was, you may need to make a large correction on your first pass followed by a small correction on a subsequent pass to get very stable.<br />
<br />
If you have version 0.11 or better, adding a set of [[RCS]] thrusters to your craft can help make minute adjustments to an orbit easier. Version 0.11 also allows you to see the current trajectory (and read periapsis and apoapsis altitudes) by switching to the [[Map view]] (M key)<br />
<br />
== Transfer Orbits ==<br />
<br />
The most efficient way to transfer from a lower circular orbit to a higher circular orbit (or vice-versa) is to use an elliptical transfer orbit, also known as a Hohmann transfer orbit. To transfer, we make the periapsis of the elliptical orbit the same as the radius of the lower orbit, and the apoapsis of the elliptical orbit the same as the radius of the higher orbit. If you are going from low to high, you make a burn in the direction of travel to elongate your orbit. You will climb in altitude as you travel around the planet to the apoapsis of your transfer orbit. Then, make a second burn to round out the new, higher orbit (as described above). To go from high to low, do the opposite: Burn in the opposite direction of travel, then fall down to the periapsis of your transfer orbit, and make a second burn to round out the lower orbit (again in the opposite direction of travel).<br />
<br />
=== Target Speed ===<br />
<br />
The key to transfer orbits is figuring out how much speed to add or subtract to reach a desired new orbital altitude. To do this, use the formula below to determine the target velocity for your initial burn:<br />
<br />
<math>v = 1,878,968 * \sqrt{\frac{2}{r_i} - \frac{2}{(r_l+r_h)}}</math><br />
<br />
In this formula, ''r<sub>l</sub>'' and ''r<sub>h</sub>'' are the radii of the lower and higher orbits, respectively, and ''r<sub>i</sub>'' is the radius of the initial orbit. If you are transferring to a higher orbit, ''r<sub>i</sub>'' will be equal to ''r<sub>l</sub>'', and ''v'' will be faster than your current speed, so burn in the direction of travel to reach ''v''. If you are transferring to a lower orbit, ''r<sub>i</sub>'' will be equal to ''r<sub>h</sub>'', and ''v'' will be slower than your current speed, so burn in the opposite direction to reach ''v''. Remember, ''v'' is the target speed for your initial burn that puts you into the elliptical transfer orbit. Once you reach your new orbital altitude, you need to make a second burn to round out your orbit, using the same technique described in the [[Tutorial: Basic Orbiting#Stabilizing_your_orbit | stabilizing your orbit]] section.<br />
<br />
Details of where this formula comes from are in the technical section below. When using this formula, take care to remember that the radius of an orbit is equal to the orbital altitude plus Kerbin's radius (600 000 m).<br />
<br />
=== De-orbiting ===<br />
The most efficient way to de-orbit from any altitude is to initiate a transfer orbit with a periapsis below 70000 m, the edge of Kerbin's atmosphere. Note that the upper atmosphere is very thin so if you do not want to wait for several orbits of aerobraking, aim for under 35000 m and thicker air. As you approach periapsis, the atmospheric drag will start to slow your craft and eventually it can no longer maintain orbit.<br />
<br />
=== R code snippet for planning Hohmann transfer ===<br />
<br />
hohmann <- function(from_alt,to_alt){<br />
# provides information needed to perform<br />
# a hohmann transfer from a circular ortbit<br />
# at from_alt (km) to a circular orbit at to_alt (km)<br />
mu <- 3530.394 # Gravitational parameter (km^3/s^2)<br />
R <- 600 # Kerbin radius (km)<br />
r1 <- from_alt+R # radius 1 (km)<br />
r2 <- to_alt+R # radius 2 (km)<br />
vc1 <- sqrt(mu/r1) # circular orbit velocity 1 (km/s)<br />
vc2 <- sqrt(mu/r2) # circular orbit velocity 2 (km/s)<br />
a <- (r1+r2)/2 # semi-major axis of transfer orbit (km)<br />
T <- 2*pi*sqrt((a^3)/mu) # period of transfer orbit (s)<br />
dv1 <- (sqrt(r2/a)-1)*vc1 # delta v1 (km/s)<br />
dv2 <- (1-sqrt(r1/a))*vc2 # delta v2 (km/s)<br />
b1 <- list(from=vc1,to=vc1+dv1) # burn one from-to velocities (km/s)<br />
t <- T/2 # time between burns (s)<br />
b2 <- list(from=vc2+dv2,to=vc2) # burn two from-to velocities (km/s)<br />
out <- list(from_alt=from_alt,b1=b1,t=t,b2=b2,to_alt=to_alt)<br />
return(out)}<br />

=== Orbital Table ===<br />
'''Note:''' The atmosphere previously had a sharp cutoff at 34.5 km, but now extends to approximately 68 km. Below this altitude, your orbit will gradually decay. The decay becomes quite rapid below about 45 km. The orbital parameters below 68 km are provided for reference, but understand that you will not be able to maintain these orbits without regular corrections to counteract the atmospheric drag.<br />

<div>{{Stub}}<br />
[[Image:EVAdev1.jpg|right|thumb|A dev picture of a Kerbal performing E.V.A]]<br />
An Extra Vehicular Activity or EVA is when your [[Kerbals]] trust their lives to the chewing gum, duck tape, and prayers that comprise their (mostly) airtight suit, and exit the [[Command Module|capsule]] to go enjoy a space walk. <br />
<br />
To start an EVA either right click on the capsule, or mouse over the images in the lower right corner. To re-enter your capsule, get close to the door and press F.<br />
<br />
The Kerbals can navigate outside their spacecraft by moving on [[ladders]], the ground, or activating their personal RCS system. The RCS system has limited fuel, with a <math>\Delta V</math> of ~520 m/s. Their EVA packs also refuel when entering a pod. <br />
<br />
Kerbals mass 0.03125 tonnes on EVA, but are massless when in a command pod.[[http://kerbalspaceprogram.com/forum/index.php?topic=17329.0]]<br />
<br />
==Trivia==<br />
If you use the Debug cheat "Infinite EVA fuel" it is possible to get to the mun and back by launching a rocket to an orbit as if trying to land on the mun and sending brave Jeb or some of the other losernauts on EVA and jetpacking...but this method can take much longer then the preferred method.<br />
<br />
It would appear that jetpacking is only possible on bodies with less than 3 m/s2 surface gravity, which rules out [[Kerbin]], [[Eve]], and [[Tylo]]. The heaviest planet on which jetpacking is currently possible is [[Duna]], although this can only be achieved with unidirectional thrust.<br />

<div> {{Delete|The mod in question is obsolete, and the rest of the tutorial doesn't provide information that isn't provided elsewhere in greater detail.}}<br />
<br />
Landing on the [[Mun]] is no easy task! With a reasonable gravity well, and no atmosphere, the rocky natural satellite conspres to make a rocky grave for Kerbanauts. This tutorial provides tips on how to land on the Mun using modded parts. Although in reality, from [[Moon landing using mods#Step 2 - Launch the rocket normally|Step 2]] it applies to any ship attempting to fly to the Mun.<br />
<br />
===Specifications===<br />
*'''Length:''' 5-10 minutes<br />
*'''Difficulty:''' Moderate <br />
*'''For version:''' 0.13 and above<br />
==Steps==<br />
===Step 1 - Getting the addon===<br />
Get the The Intrepid SLS Rocket from [http://kerbalspaceprogram.com/forum/showthread.php/3396-Industrial-Flames-Explosions-Inc-Version-1-4-2-Now-Available! here], or a number of other modded parts to make your journey easier.<br />
<br />
Suggested parts to find include:<br />
* Larger Solid Rocket Boosters<br />
* Lunar Landing Module (LEM/LM)<br />
* Larger Liquid fuel tanks<br />
<br />
===Step 2 - Launch the rocket normally===<br />
<br />
Fly up to about 15,000 Metres vertically. At this point, begin "the tilt" East or West. Once about about 65-70,000m, you are out of the atmosphere and can transfer your upwards energy into east-west speed.<br />
<br />
===Step 3 - Go to the [[Mun]]===<br />
<br />
Difficult on first glance, a rule of thumb will help you get there.<br />
<br />
* Wait for Mun-rise to finish from an approx. 100,000m orbit<br />
* Burn to raise your apoapsis to between 11.5 and 12.5 million.<br />
* Get captured by the Mun's gravity.<br />
<br />
===Step 4 - Land on the Mun===<br />
<br />
* Once captured by the Mun, Retro-burn to first counter-act the slingshot, past, slowing into an eliptical orbit.<br />
* Continue retro-burn to place Periapsis on the surface of the Mun.<br />
* From here, several large burns, or one long gentle burn will be required to negate your horizontal and vertical speed.<br />
* Aim to <del>hit the surface</del> land with less than 5 m/s vertically and less than 3 m/s horizontally to ensure a safe landing.<br />
* Keep SAS on, to stabilize the vehicle on landing.<br />
<br />
===Step 5 - Return to Kerbin Optional===<br />
<br />
* If your rocket has the fuel to reach the Mun's escape you can most probably return to Kerbin.<br />
* First fire your rockets but monitor your map view for the point at which you reach the Mun's escape velocity and cut the rockets.<br />
* Once in the gravity well of Kerbin burn to lower Periapsis to lower the 70,000m.<br />
* Warp to your Periapsis. Lower than 70,000m the drag from the atmosphere of Kerbin will lower your orbit without the need for additional burns.<br />
* With luck you will have some fuel left that can be used for canceling extra vertical and horizontal velocity before the opening of your parachutes or a power landing. (Parachutes are much easier than power landings on Kerbin.)<br />
<br />
==Finishing word==<br />
<br />
Flying to Mun is a great achievement and one which all aspire to accomplishing. This guide should help you to achieve your goals and begin to look at even more challenging possibilities in KSP!<br />
<br />

'''Duna''' is the fourth planet of the [[Kerbol]] star system. It is the Mars analog for Kerbal Space Program and is mostly red with polar icecaps. It has one natural satellite, the [[moon]] '''[[Ike]]'''. Due to Ike's size and proximity, Ike and Duna are tidally locked to each other.<br />
<br />
== Topography ==<br />
{|<br />
|<br />
[[File:Duna Topo ISA 3200x1600 compressed.png|thumb|right|A topographic map of Duna made with the ISA MapSat plugin]]<br />
Duna is a iron-rich planet which has greatly varying land altitude, the consequence of which is very difficult judgment of a safe landing position. Its mountainous ranges are a peril to landing craft, especially considering the thin atmosphere, where very little aerobraking can be done safely. It is important to slow one's ship down before coming into the atmosphere, to ensure a safe descent. There are several maria, or large regions of Dark soil at, exactly 0 meters altitude. These are ideal landing locations due to their low altitude, and thicker atmosphere for aerobraking. Its two poles are very expansive and are the result of a thin atmosphere. The lower regions make a shape resembling Europe.<br />

<br />
== Atmosphere ==<br />
{|<br />
|<br />
[[File:Atmosphere_kerbin_duna.png|thumb|right|A comparison of the atmospheres of Duna and Kerbin]]<br />
<br />
Duna's atmosphere begins at 41,446 m. It is only 20% as dense as [[Kerbin|Kerbin's]] at altitude 0 and is even less dense (relative to Kerbin) at higher altitudes.<br />
<br />
Like the atmospheres of [[Eve]] and Kerbin, Duna's atmosphere fades exponentially with increasing altitude (with a scale height of 3000 m). In general, the atmospheric pressure on Duna at an altitude expressed in meters is:<ref>A [[LV-N Atomic Rocket Engine|nuclear engine]] has a specific impulse of 220 in 1 atm, 800 in vacuum, and the following at various Duna altitudes:<br />
{| class="wikitable"<br />
| altitude (m) || 2 || 100 || 300 || 500 || 1460 || 2420 || 3000 || 4272 || 5000 || 10000<br />
|-<br />
| specific impulse || 684.1 || 687.8 || 695.1 || 701.8 || 728.7 || 748.2 || 757.3 || 772.1 || 778.1 || 795.9<br />
|}</ref><br />
<br />
: <math>p_d = 0.2\ e^{-altitude/3000}</math><br />
<br />
Parachutes work at lower efficiency than on Kerbin, making powered descent necessary when landing from orbit (unless your craft is a glider or just a pod with a parachute).<br />
|}<br />
<br />
== Orbital Statistics ==<br />
The [[w:geosynchronous_orbit|geosynchronous orbit]] of Duna is at an altitude of<br />
{{OrbitAltitude | period_s=65517.859375 | mass_kg=4.51548115036107e21 | radius_km=320 }} above Duna. The speed of the satellite is<br />
{{OrbitVelocity | period_s=65517.859375 | mass_kg=4.51548115036107e21 | radius_km=320 }} and it has an orbital period resonating with 1 Duna day (18.2 hours or 65517.859375 seconds).<br />
<br />
For a [[w:semi-synchronous_orbit|semi-synchronous orbit]] of ½ Duna day (9.025 hours or 32490 seconds) an orbit of<br />
{{OrbitAltitude | period_s=32758.9296875 | mass_kg=4.51548115036107e21 | radius_km=320 }} above Duna is needed with a velocity of<br />
{{OrbitVelocity | period_s=32758.9296875 | mass_kg=4.51548115036107e21 | radius_km=320 }}.<br />

'''Tylo''' is one of the four [[moon]]s of [[Jool]]. It has a rocky surface. It is extremely challenging to land on because it possesses a similar gravity well to [[Kerbin]] itself, while lacking the benefit of an atmosphere to brake in.<br />
<br />
== Geology ==<br />
Tylo is a large rocky moon of Jool. It has a varying elevation between 0 meters (Tylo baseline height) and peaks of more then 6290 meters. <br />
Tylo shows signs of many large asteroid impacts. <br />
Due to the coloring of the surface of Tylo, it is likely that it is covered in a rhyolite layer of rock and dust, spread by meteorite impacts.<br />
Although very large in comparison to other moons, it is unlikely that it is a captured planet. For a planet of this size, Jool would have to be much larger and denser to produce a large and strong enough gravitational well.<br />
