Kerbals also appear to be warm-blooded, given their ability to sweat. Although Kerbals appear mostly hairless, they have notable hair growth occurring on the top of their heads and Wernher von Kerman can be seen to have a mustache.
Their skin hues appear to range from light green to pale green, if they range at all. One of the load screen arts on the latest (1.x) versions of KSP shows Kerbals with multiple human-like teeth. However, this may be due to the cartoonish art style of the game and not actual fact. Judging by official artwork and in-game models, Kerbals appear to have two large teeth that span the length of their gums, one on the mandible and one on the skull. They also possess no eyelids, and as a result do not blink. Kerbals appear to lack any irises, or they are perfectly black in color. Kerbal eyes protrude from their heads significantly, as do their corneas from the eyes. Kerbals have massive heads with respect to their bodies, with roughly half of their total volume accounted for the head. Kerbal astronauts are often called " Kerbonauts". These Kerbals can be retrieved as part of the contract, and used as Kerbonauts.
The only Kerbals seen in-game work at Kerbal Space Center or are found in orbit during specific contract missions. īefore 1.11, the Kerbal's mass only counted toward the mass of a craft if seated in an EAS-1 External Command Seat, and added no mass to any part that can hold a kerbal. When placed inside a command pod, a crew cabin (eg: PPD-10 Hitchhiker Storage Container) or the Mobile Processing Lab MPL-LG-2, they add mass to the part thus (compared to older version) anything that can hold a Kerbal was reduced to compensate for this change. When including the parachute and jetpack, a Kerbonaut has a mass of 93.875kg. As of 1.11, a Kerbal in an EVA suit, without jetpack nor parachute, has a mass of 45.0 kilograms (99.2 lbs.), which is 0.045 in-game Mass units. They stand roughly 0.75 meters tall (2'5½"). Kerbals display no variance in height or weight. Kerbals are the native denizens of the planet Kerbin, and cartoonish in-game analogs for humankind. Bob Kerman on EVA next to the Mun in version 0.25
