| − | '''Eve''' is the second [[planet]] from [[Kerbol]], the closest planet to [[Kerbin]], and KSP's analogue for the planet [[w:Venus|Venus]]. It has one small moon: a captured asteroid called '''[[Gilly]]'''. It is especially notable for its extremely thick, dense atmosphere, which makes aerobraking and returning two of the most dangerous activities in the game. Additionally, Eve has the greatest surface gravity of all the planets, and the second highest escape velocity, second only to [[Jool]]. | + | '''Eve''' is the second [[planet]] from [[Kerbol]], the closest planet to [[Kerbin]], and KSP's analogue for the planet [[w:Venus|Venus]].

| − | The surface of Eve looks not unlike that of Saturn's largest moon, Titan. It has several oceans, among which lie large, flat continents. The terrain has a few mountain peaks but mostly consists of rolling hills that resemble purple sand dunes. These are speckled with small boulders, no doubt worn down by Eve's pressure, temperature, and winds. Eve's surface is covered with craters. Eve's highest mountain range has a peak of 7526 m.

| |
| | | | |
| − | Eve has an extremely dense [[atmosphere]] with a mass of approximately 1.9×10<sup>17</sup> kilograms, a sea level pressure of 506.625 kilopascals (5 atmospheres), and a depth of 90,000 meters. Compared to the atmosphere of [[Kerbin]], Eve's atmosphere has 4 times the mass and 5 times the sea level pressure. At an altitude of 10,577 m on Eve, the atmospheric pressure is the same as at sea level on Kerbin (1 atm). The pressure at the top of Eve's highest mountain peak is 1.5 atm.

| − | | |
| − | The average [[w:Molecular_mass|molecular weight]] of Eve air is 43 g/mol, and its [[w:Heat_capacity_ratio|adiabatic index]] is 1.20. Although the composition of Eve's atmosphere is unknown these values suggest that it may consist largely of [[w:Carbon_dioxide|carbon dioxide]]. Another possibility is that the atmosphere is filled with ethane gas (C<sub>2</sub>H<sub>6</sub>, with a heat capacity of 1.2 and a molecular weight of 30 g/mol) and other compounds. If we assume LiquidFuel is kerosene, the joke that the lakes of Eve are LiquidFuel is strengthened by the purple colour since it is often mixed with a purple dye prior to sale. With a thick atmosphere filled with hydrocarbons, it's easy to imagine reactions that would yield compounds such as RP-1, the grade of kerosene used as rocket fuel. An atmosphere of 90% CO<sub>2</sub> and 10% C<sub>2</sub>H<sub>6</sub> would have molecular weights and adiabatic indexes close to what is seen on Eve, though there are other combinations of gases that would work as well.

| − | Like all other atmospheres in the game, Eve's atmosphere fades exponentially as altitude increases. The [[w:Scale_height|scale height]] varies with altitude, which is a change from pre-1.0 [[Version_history|versions]] of the game. The pressure-altitude profile is globally constant and independent of temperature. The following table gives the atmospheric pressure at various altitudes above sea level.

| − | The surface of Eve is very hot, with a globally averaged sea level temperature of approximately 135 °C. Except for a small inversion layer between 50-60 km at low latitudes, air temperatures decrease with increasing altitude up to an altitude of 70 km. Above 70 km, the rarified atmosphere warms as altitude increases. Despite the hot surface temperatures, the lack of a [[w:Stratosphere|stratosphere]] means that Eve's atmosphere is cooler than Kerbin's at altitudes above ≈26.5 km. The temperature rise above 70 km suggests the presence of a [[w:Thermosphere|thermosphere]].
| |
| − | | |
| − | Air temperatures vary with latitude and time of day. At the equator, sea level temperatures vary between a nighttime low of 147 °C and a daytime high of 156 °C. At the poles, the temperature varies between 87 °C and 95 °C. Since Eve has no axial tilt, there are no seasonal temperature variations.
| |
| − | | |
| − | From within Eve's atmosphere, the sky appears indigo during nighttime and a violet-purple color during the daytime. During dawn and dusk, the sky is green. The color of Eve's sky is likely due to wind-borne dust from Eve's purple surface, though it has also been suggested that iodine gas could be an atmospheric constituent.
| |
| − | | |
| − | === Atmospheric flight ===
| |
| − | | |
| − | The thickness of Eve's atmosphere makes it well suited for [[aerobraking|aerocapture]] from a high-speed interplanetary intercept. The periapsis altitude required for a successful aerocapture depends on the spacecraft's drag characteristics, its approach velocity, and the desired apoapsis of the resulting orbit. The most effective periapsis for aerocapture is best determined experimentally; however, for a Hohmann transfer originating from Kerbin, it is found that the median value is about 62 km. Heat shields are required to prevent destructive overheating.
| |
| − | | |
| − | [[Parachute]]s work very effectively in Eve's dense atmosphere. A vehicle in Kerbin's atmosphere would require 3 times as much parachute area to attain the same descent rate on Eve.
| |
| − | | |
| − | Landing legs on Eve can easily break because of Eve's high gravity and, surprisingly enough, atmospheric pressure.
| |
| − | | |
| − | Because of Eve's high atmospheric pressure, rocket engines perform poorly at low altitudes. The engines best suited for low altitude use on Eve are the [[T-1 Toroidal "Aerospike" Liquid Fuel Engine|Aerospike]], [[S3 KS-25 "Vector" Liquid Fuel Engine|Vector]], and [[S3 KS-25x4 "Mammoth" Liquid Fuel Engine|Mammoth]].
| |
| − | | |
| − | Jet engines do not function in Eve's atmosphere since it contains no oxygen — they make noise and consume fuel, but they produce no thrust. Planes with other propulsion methods do, however, work very well, and are a great way to explore the planet. They work best between 35 km and 25 km where the atmosphere generates enough lift to glide and steer, but not enough drag to slow the aircraft excessively.
| |
| − | | |
| − | ==Oceans==
| |
| − | | |
| − | A large portion of Eve is covered in oceans of "Explodium",<ref>The oceans are referred to as "Explodium Seas" by science experiments</ref> a liquid with a density of 1.5 tonnes per cubic metre<ref>[http://forum.kerbalspaceprogram.com/content/358-KSP-1-0-5-is-live! As of 1.0.5], oceans now have explicit density values: Eve's oceans now have a density of 1.5 tonnes/m<sup>3</sup> while water has a density of 1.0 tonnes/m<sup>3</sup>.</ref> that is heavily implied to be a form of rocket fuel. A real-world liquid that closely fits the properties of explodium is hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>), which has a density of 1.450 tonnes per cubic metre and can be used as a monopropellant.
| |
| − | | |
| − | Eve is one of only three celestial bodies with oceans, alongside Kerbin and [[Laythe]].
| |
| − | | |
| − | == Science ==
| |
| − | | |
| − | Eve's orbit and atmosphere have a science multiplier of 7, which is rather average. But the surface has a multiplier of 12, which is the third highest science multiplier in the [[Kerbol System]]. Eve has 15 [[Biome]]s with their own science to be collected. Its main features are a large Explodium Sea with some scattered Islands and Shallow areas as well as a Main Continent and Poles. Within the Continent lie three large bodies of liquid, one being a Crater Lake. There are also areas covered with Impact Ejecta.

| − | == Natural satellites ==
| |
| − | Eve's only natural satellite is the tiny captured asteroid [[Gilly]] in a highly eccentric and inclined orbit. Gilly is the smallest celestial body in the [[Kerbol]] system and has the lowest surface gravity of any celestial body.
| |
| − | | |
| − | == Orbital statistics ==
| |
| − | | |
| − | Visiting Eve potentially requires the least [[delta-v]] of any planet because its huge gravity well and dense atmosphere mitigate the difficulties that its slight relative inclination poses and greatly ease aero-captures, transfers, and landings; unfortunately, takeoff and escape therefore require the most delta-v of any celestial body with a solid surface.
| |
| − | | |
| − | The combination of high gravity and thick atmosphere makes return missions from the sea level of Eve very difficult. It requires about 7,000-7,500 m/s of delta-v to get into orbit from sea level. Driving to and launching from the peak of one of Eve's mountains can drastically reduce the amount of delta-V required (thus allowing successful launches with significantly lighter rockets). The highest peak on Eve since {{version|0.21.1}} is 7540 m high, found near (25° S, 158.5° W)

| − | == Bugs ==
| |
| − | | |
| − | * Eve has higher gravity than [[Kerbin]], restricting a Kerbal's jump to only half a meter and making EVA jets useless. This being said, if a [[Kerbal]] falls from more than 4 m, they will hit the ground much harder than on Kerbin, which may cause a glitch to happen in which they will clip into the terrain and accelerate away from Eve at phenomenal speed, sometimes faster than the speed of light itself, usually sending the unlucky Kerbal on an escape trajectory from [[Kerbol]] if they are not killed by the fall. They may bring something into interstellar space with them if they hit an object instead of the ground.
| |
| − | * [[Solar panel]]s will probably break off in flight, even with very low velocity. It's best to wait to extend them till stable on the surface, however, they can break on the surface of Eve even when retracted. This may be due to Eve's high gravity.
| |
| − | * Rovers can be challenging to drive on Eve due to its gravity, as the rover's wheels will easily break, but on the upside, since the gravity pulls them lower on their shocks and thus lower the centre of mass, they will be harder to flip over. Although not a glitch, it could cause clipping issues with a Kerbal sitting in [[EAS-1 External Command Seat]]s
| |
| − | | |
| − | *When landing fast, a craft will sometimes sink into the surface of Eve. This can be fixed by using landing legs or engines to lift the ship up.
