Infrastructure for a multi-planet civilization
Planet Prep Technologies
We build skyhooks, a segmented Venus sunshade, and mass drivers—the core systems that make large-scale space logistics and climate engineering possible. We sell prototypes, licensing, and mission integrations to launch providers, national programs, and ISRU partners.

/ What we make
Skyhooks / Tethers
Momentum-exchange ladders that move mass between orbits with minimal propellant. Tip-capture, webbed multi-strand tethers, autonomous rendezvous.

Venus Sunshade
Segmented, SRP-balanced mirror at Venus L1 to throttle insolation and trigger CO₂ rain/freeze. Deployable films, tensioned booms, robotic alignment.

Mass Drivers
Electromagnetic launchers for bulk CO₂/ice/regolith. Close the momentum loop with tethers; enable off-world industry and planetary cleanup.
