KOS-14

Lore & Background

The Kerbal Space Center maintains a standing roster of sixteen Kerbal astronauts, each assigned a sequential KOS number. The early numbers—Jebediah, Bill, the first Bob, Valentina, and the first Linus—carry the weight of the program's founding era, when the first wobbly rocket finally cleared the atmosphere and someone, somewhere, screamed with joy. The later numbers, including KOS-14, represent the steady expansion of the program: more Kerbals, more missions, more reasons to need a second set of parachutes.

Kerbals themselves are a small, green species with disproportionately large heads and thin, spindly limbs. They wear white-and-orange pressure suits when they suit up, and their faces are a single wide grin that never changes regardless of whether they are about to land on the Mun or crash into the desert at 4,000 meters per second. This unchanging expression has become a beloved part of the community's affection for the species: the Kerbal face says, essentially, 'I am about to do something catastrophically stupid, and I am thrilled about it.'

In the broader KSP cosmology, Kerbin is a blue-green world orbited by two moons, the Mun and Minmus, and surrounded by a family of planets stretching from the scorching rock of Moho to the gas giant Jool and its icy satellites. KOS-14, as a Linus, fits naturally into the tradition of Kerbals who are as comfortable in a lab suit as in a cockpit, running experiments on the Mun's surface or simply existing as a passenger while the player (the 'director') handles the flying.

In Their Own Story

The launch window opened at 0647 Kerbin Standard Time, and KOS-14 was already in the suit, the white fabric creaking as he flexed his thin fingers against the control stick. The flight director's voice crackled through the comms, calm and slightly under-rehearsed, reciting the pre-flight checklist for the fourteenth time. Around him, the hangar smelled of burnt fuel and cold coffee.

'KOS-14, you are go for launch,' the voice said.

KOS-14's wide head tilted. His grin did not change. It never changed. Somewhere in the back of his mind, a small, very green part of him was already calculating the delta-v budget for the Mun orbit insertion, because that is what Linuses do: they do the math while the world on fire.

The engines lit. The hangar shook. And KOS-14, KOS-14, KOS-14 rose, green and grinning, into the black.

Reader's Guide

Full name: Linus Kerman. Crew ID: KOS-14. Role: Astronaut, pilot, and science passenger at the Kerbal Space Center. Career arc: As a mid-roster Kerbal, KOS-14 enters the program after the founding flights and becomes a regular on interplanetary and lunar missions, serving in whatever seat the current mission requires—pilot, co-pilot, or the Kerbal strapped to the science bay window running experiments while the ship vibrates dangerously. Notable missions: In the sandbox and career modes, KOS-14 is available for any mission the player constructs, from simple suborbital hops to multi-planet tours of the Jool system; the community has no single 'canon' mission attached to this specific number, making KOS-14 a blank canvas for the player's own story. Cause of death: None fixed in canon; in the sandbox, any Kerbal can be lost to a botched landing, a fuel leak, or the simple act of forgetting to deploy the parachute, and the KSC memorial wall grows by one small green head. Fan memes and inside jokes: KOS-14 shares the 'Linus' identity with several other roster members, and the community affectionately treats all the Linuses as interchangeable science nerds. The broader 'Bob' and 'Valentina' name-cycling jokes extend to the Linuses, and KOS-14 is often the Kerbal players pick when they want a 'smart' passenger without thinking too hard about it. The unchanging grin on the Kerbal face is the single most memed visual in the entire game, and KOS-14 wears it with the same serene, slightly unhinged confidence as everyone else.

Did You Know?

• The KSC roster cycles through the names Bob, Valentina, and Linus after the founding five, meaning there are multiple Kerbals sharing the same surname and first name, distinguished only by their KOS number.
• Kerbals' faces are a single fixed grin that does not change expression in any flight phase, a design choice that has become one of the most iconic and memed visuals in the game.
• In the game's career mode, Kerbals must be trained in specific skills—pilot, engineer, scientist—before they can serve in those roles, and KOS-14 like any other must earn those qualifications before boarding a mission.
• The Kerbal home planet, Kerbin, is orbited by two natural satellites, the Mun and Minmus, both of which are popular early-career destinations and both of which have claimed their fair share of Kerbal lives in the communi
