Relativity Space builds rockets. Tim Ellis and Jordan Noone founded the company in 2015, after both had worked at Blue Origin and SpaceX respectively. It is based in Long Beach, California.
The company first became known for using large metal 3D printers to make rocket parts. Its first rocket, Terran 1, was mostly 3D printed and launched once in 2023. It reached space but did not reach orbit. After that flight the company retired Terran 1 to focus on a much larger rocket.
That rocket, Terran R, is a reusable medium to heavy lift launch vehicle meant to carry satellites to orbit. Relativity has signed launch contracts with satellite operators, and it plans to launch Terran R from Cape Canaveral in Florida. It has moved away from printing most of the rocket and now uses more standard manufacturing for many parts. In 2025 the former Google chief executive Eric Schmidt took a controlling stake and became chief executive. The company remains privately held.
