Kerbal Space Program Wiki

Kerbals, as they appear in Kerbal Space Program.

Kerbals are a race of small green humanoids who are native to the planet Kerbin, serving as a in-game analogs for humans in Kerbal Space Program.


The Kerbals are basically humans, just with green skin and strange vocal patterns. Kerbals can be pilots or occupants of spacecraft/planes, and show a mathematical prowess, being able to calculate and analyze scientific data. They also have a Courage and Stupidity bar, which, besides changing their facial expressions during flight, appear to do nothing. The four most well-known Kerbals are Bill, Jebediah, Bob, and Valentina Kerman. It also seems that most of the Kerbial's names are 2 words: a common name + a noun. For example, Johnhat Kerman. It should be noted that Kerbals have the last name Kerman.

The Kerbal Courage and Stupidity bars.

 It is quite obvious that the kerbal design is based off of the stereotypical martian, excluding the eyes and square head.  Kerbals also seem to be able to bounce off of almost any surface without dying.
