Relativity Space

Relativity Space is headquartered in Los Angeles, CA.

Building humanity’s multiplanetary future.

Relativity Space builds reusable rockets, including the Terran R vehicle, intended to make access to space more reliable and routine for science, exploration, and business.

The page cites specific Terran R payload performance figures (23,500 kg to LEO downrange landing, 33,500 kg to LEO expendable) and describes an engineering approach of prototyping early, testing often, and iterating fast to scale production and reduce cost.

Founder Tim Ellis previously worked on metal 3D-printing technology at Jeff Bezos's Blue Origin before starting Relativity, which has since raised over $2.4 billion to build 3D-printed rockets.
