Launch anytime from anywhere

Born out of a design for Mars ascenders, Eiger rocket is lightweight, quick to assemble and powered by propellants that don’t require cryogenic storage facilities.

Lowering the cost of space access

$1M for a dedicated rocket to launch 150 kg payload to LEO. 80% of rocket cost in the traditional space industry is related to personnel. Pythom runs small teams and tight facilities, building in the spirit of early explorers such as Lewis & Clark, and Roald Amundsen.
