List of easter eggs

“

An Easter Egg is an intentional inside joke, hidden message, or feature in a work such as a computer program, video game, movie, book, or crossword.

— Easter egg (media) on Wikipedia

”

In KSP this corresponds to any anomalous formations on the surfaces of bodies in the Kerbol System (or indeed on the Main Menu, in IVAs, or anywhere really) which have been deliberately added by the developers. This does not include things which were not added deliberately, like terrain glitches. Some say that some of these easter eggs remain undiscovered as of today.

Oh look, a preamble!

If you've stumbled here accidentally and don't want to spoil the thrill of exploration and discovery for yourself,
this excessively large text block will do its best to keep you from glancing below before you remember where the "back" button in your browser is, or a keyboard combination like ⎇ Alt+← if you're fancy.

Seriously, these contain quite detailed descriptions of the easter eggs.
There are even pictures of some of them.
There are even coordinates for all of them.
So if you want to see them first when you find them yourself, go back now!

I really mean it, don't tell me you weren't warned.
If you aren't interested in spoilers there are other things you could do.

Maybe you'd like to go to the Main Page instead of continuing to read this well-intended textual clutter.
Maybe you just like reading too much. Maybe you should be playing KSP instead.
Maybe you should go buy it if you haven't already.
Maybe you should buy it for someone else who loves science, indie games or Mexican innovation.

I don't know;

I'm just a rapidly waning text block.

YOU HAVE BEEN WARNED!

Kerbol

None known

Moho

Although itself a terrain glitch, the Mohole (a large, steep vertical "tunnel" at Moho's north pole) could be considered an easter egg, since anomalous forces are present around its rim, which may well be deliberate.

Eve

None known

Gilly

None known

Kerbin

Five Monoliths: one visible from KSC, one by the tracking station at the Inland Kerbal Space Center (20° 40′ 15″ N 146° 29′ 48″ W), one at 35° 34′ 13″ N 74° 58′ 38″ W, one at 0° 38′ 25″ S 80° 46′ 0″ W, and one at 28° 48′ 30″ S 13° 26′ 24″ W
Destructible memorial to the old Mk1 Command Pod outside the level 3 VAB.
A temple in the desert (6° 30′ 20″ S 142° 41′ 8″ W)
A crashed flying saucer on northern ice cap (81° 57′ 18″ N 128° 30′ 50″ W)
The Old Airfield (1° 31′ 43″ S 71° 54′ 8″ E) has a hangar containing old versions of these parts: a Command Pod Mk1 (but scorched and oversized), an FL-T400 Fuel Tank and an LV-T45 Liquid Fuel Engine.
The level 3 flagpole at KSC can be climbed by Kerbals.
When the level 3 Astronaut Complex is destroyed, a toilet is visible in the rubble.
In the ocean just south of the KSC, about midway between land and the southern ice cap (about 30° 0′ 0″ S 80° 0′ 0″ W), engraved into the ocean floor is a giant smiley face, best seen from orbit or on a topography map like File:Kerbin heightmap.jpg.
'Graffiti Rock' on the south side of the island ENE of KSC (5° 21' 4" N, 298° 4' 58").^[dubious]
Near KSC there is a 'forest' of three-dimensional trees near a 'lawn' with three-dimensional grass approximately the same size as a Kerbal.

The Giant Kerbal Face of Duna

The camera which looks like that of the Curiosity rover, buried in the soil (visible on only high terrain detail at 30° 20′ 30″ S 28° 48′ 37″ W)
Hill making SSTV signal (66° 3′ 12″ S 160° 53′ 38″ W but the source of the signal is now several hundred meters beneath hill as of 0.22)

Ike

Magic Boulder - Missing since 0.18 - The magic boulder used to orbit Ike at an altitude of 15 km with zero eccentricity and an inclination of 80 degrees. The mesh (physical surface) for the magic boulder did not match its texture (visible surface) which could result in ships apparently digging into the surface with no ill effect. It would also cause ships to explode seemingly spontaneously, sometimes metres away from the surface, displaying "vesselname crashed into Magic Boulder" in the Flight Log. It also seemed to glow green as if radioactive, and there was a monolith on its leading edge. The boulder had no gravity, did not appear in the map view and could not be targeted, much like any other easter egg, except in orbit. The Magic Boulder is believed to still be somewhere in the game's code.

Dres

None known

Jool

None known

Laythe

None known

Vall

Formation on Vall

Stonehenge formation, sometimes known as Vallhenge (60° 5′ 10″ S 83° 46′ 48″ E)

Tylo

Crater with Carl Sagan's face [Removed]
Cave-like formation (40° 11′ 58″ N 174° 0′ 5″ E) Ironically enough, the cave is hundreds of metres below the ground (since 0.23)

Bop

Dead Deep Space Kraken (68° 25′ 48″ N 116° 59′ 24″ E)

Pol

None known

Eeloo

None known.

Overall

While not easter eggs per se, the exact geographical poles of most bodies have highly unusual topography, usually making them inaccessible, see terrain glitch.

Kerbals

An average of the skin color in Kerbal arm textures compared to the rumored colors

The color of the Kerbals' skin is close to is #BADA55 ( ) in hexadecimal but does not match it exactly. The hexadecimal RGB value spells like “badass” in leetspeek. Some say #84D455 ( ) is the color of a Kerbal which is even further away than #BADA55. This connection is rumored, because Kerbals can have a BadS flag, which is usually interpreted as badass.

IVA

Some of the cockpits have post-it notes and other humorous writings inside them. The writing is somewhat blurry on normal settings and hard to read, but still legible. For transcripts of the notes, see the respective part pages.

Parts

On the Z-100 and Z-400 Rechargable Battery, the logo claims the batteries are Batt Man Batteries. This is a reference to Batman.
On the Communotron 88-88 is the hexadecimal number 0x62656570. When 0x62656570 is converted to ASCII it spells "beep".
Also on the Communotron 88-88, is the serial number 04101957, which is the launch date of Sputnik 1, 4 October 1957.
When the Mystery Goo™ Containment Unit is opened, revealing the holes, if one looks very closely in them, a faint smiley face can be seen.
When the SC-9001 Science Jr. is open, a message can be seen printed on the rear of the bay reading "Danger! Science Stuff".
The COSPAR designations and names of both the International Space Station and Mir (in Cyrillic script) are printed on the Mobile Processing Lab MPL-LG-2 hull.
The FL-T200 Fuel Tank has a very faint drawing on it which can just about be observed when fully zoomed in. The drawing becomes more visible during re-entry and appears to depict a failed re-entry procedure which has then been crossed out.

Loading Screen

While not that much of an Easter Egg instead of a reference, the loading screen makes a reference to The Hitchhiker's Guide To The Galaxy, stating "Answering Ultimate Question" one of the well known phrases from the book.

Main Menu

One of the two main menu images is that of a Kerbal standing on the Mun's surface, with Kerbin in the background. There is a 1 in 40 chance that a sand castle made of Mun dust can be seen at his feet.
There is another main menu image with multiple kerbals, apparently digging out the crashed lander. Note that this is not in the stock game and is in fact added by the toolbar mod.

The Mun dust castle.

Scenarios

The Kerbal XX orbiting Duna

During the Space Station One scenario, by zooming out far enough to show the planetary map, a ship by the name of 'Kerbal XX' can be seen orbiting around Duna in a near-equatorial orbit (as of 0.23)
