Relativity Space
Relativity Space is an aerospace manufacturer building Terran R, a reusable medium-to-heavy lift orbital launch vehicle produced with the company's proprietary Stargate metal 3D printing platform in Long Beach, CA. The company sells launch services - dedicated and rideshare payload missions to LEO and GTO - to government, commercial, and telecommunications customers. Relativity Space does not publish a public developer API; its developer-facing artifact is the Terran payload user's guide (mission integration documentation), not a programmatic interface.
