The mission failed: 2nd stage engine failed to reach full thrust after slow response of main valves and failure in pressure increase of the liquid oxygen turbopump. Presence of vapor bubble at the LOX pump inlet is suspected. The launch window ran from 02:00 to 05:00 UTC. It was Relativity Space's 1st launch, 1st this year and humanity's 6,412th orbital launch attempt. It was the 1st Terran 1 flight. The payload was bound for low Earth orbit (LEO).
