List of easter eggs

From Kerbal Space Program Wiki
Jump to: navigation, search


This article contains spoilers. Linking to a subsection is not recommended as this will skip over this warning.

There are numerous anomalous formations on the surfaces of bodies in the Kerbol System. Some remain undiscovered as of today.

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. 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 or indie games or Mexican innovation. I don't know; I'm just a rapidly waning text block...


  • None known


  • There are large, steep vertical "tunnels" that could be considered easter eggs, and anomalous forces are present around the rim of each tunnel.


  • None known


  • 0 degrees, 0 degrees, there is a perfect square pyramid.



  • Three monoliths
  • Three mun Arches
  • Neil Armstrong Memorial
  • Crashed Flying Saucer


  • One monolith
  • Broken terrain on north pole.


  • Giant Kerbal face
  • The camera which looks like that of the Curiosity rover, buried in the soil (visible on only high terrain detail)
  • Hill making SSTV signal (source of signal now several hundred meters beneath hill as of 0.22)


  • Magic Boulder - There is a monolith on the boulder. Boulder contains strange clipping boundaries that can result in your ship exploding seemingly spontaneously. It also seems to glow green as if it is radioactive. (M.I.A. since 0.18.)
  • A pyramid at the north pole similar to the one on Kerbin that flips the kerbals.

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


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.


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


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

The Mun dust castle.
  • 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.


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)
