Almost every AI in orbit today belongs to a government, a defense program, or a billion-dollar company. KENSAT belongs to one person — Ken — and runs a real language model on a satellite he designed, owns, and operates himself.

The goal is simple: put a thinking machine in space that is accessible to all.

About the size of two stacked tissue boxes and roughly two kilograms, KENSAT will fly in a 520 km sun-synchronous orbit and circle the planet about sixteen times a day.

On board: a tiny always-on flight computer that keeps the satellite alive, a GPU that runs the language model, a UHF radio for talking to the ground, and a small lithium battery topped up by body-mounted solar panels.

The radio antenna is a pair of tape-measure strips that spring open the moment the satellite is ejected from its deployer. No motors, no actuators, no moving parts that can fail.
