Relativity Space using SSC

Another commercial space company is using Stennis Space Center, Miss., to test rocket engines. Relativity Space is still keeping mum about its work, but the co-founder and CEO Tim Ellis was at a Capitol Hill meeting during the week and said the Los Angeles-based company is testing at SSC. The meeting was before the Senate Subcommittee on Space, Science and Competiveness, and the focus was on public-private space partnerships. "Relativity has begun testing of our liquid oxygen/liquid methane engine with over six dozen hot fires across multiple test articles at NASA Stennis Space Center, with plans for continued routine testing," said Ellis, a former engineer with Blue Origin. His partner, Jordan Noone, was formerly with SpaceX. (Source: GeekWire, 07/13/17) NASA, Space X, Aerojet Rocketdyne and Blue Origin also test or have tested rocket engines at SSC.
