March 22, 2023, at 11:25 p.m. — Relativity's Terran 1 rocket launches on its debut flight toward a low Earth orbit from Launch Complex 16 at Cape Canaveral Space Force Station in Florida. The rocket experienced an upper stage anomaly and did not reach orbit, but the test flight validated Relativity’s 3D-printing approach by passing through maximum dynamic pressure and achieving stage separation after main engine cutoff.
