[ HOW ]

Engineering downmass. Returning what orbit creates.

3Space operates the in-space infrastructure stack — unmanned labs and orbital return vehicles that let companies build, launch, test, and refine commercial solutions in orbit, then bring the payload home.

Our modular, ride-sharing labs open fast and affordable access to low Earth orbit for research, manufacturing, biotech, and hypersonics. No bespoke spacecraft program. No multi-year wait.

ReX — our origami-inspired orbital return vehicle — carries the largest deployable heat shield in its class, so more mass comes back, in more volume, at better economics. From contract to launch in under sixteen months.

[ TECH ]

ReX — the largest deployable heat shield in its class

An origami-inspired hypersonic decelerator that unfolds on re-entry, slows controllably through the atmosphere, and protects the payload all the way down. More thermal protection area means more recoverable mass — in usable volume, at orbital-economy pricing.
