Relativity Space attempts world's first 3D-printed rocket launch for third time.
Relativity Space is set to launch its Terran 1, the world's first 3D-printed rocket, from Florida's Cape Canaveral Space Force Station tonight. The rocket is designed to haul up to 2,756 pounds to low Earth orbit and uses liquid methane as a fuel and liquid oxygen as an oxidizer. The launch will be the third attempt after previous attempts were scrubbed due to fuel-temperature issues and weather and range safety delays. The Terran 1 is a test flight for Relativity Space, which was founded in 2016 and plans to use the data to inform the development of its next launch vehicle, the reusable Terran R.
