Relativity Space is preparing for a third launch attempt for the first flight of its Terran 1 rocket Wednesday, in an effort to become the first 3D-printed and methane-fueled rocket to reach orbit. The Good Luck, Have Fun (GLHF) mission is now scheduled for liftoff from Launch Complex 16 (LC-16) at the Cape Canaveral Space Force Station in a window from 10:00 PM EDT Wednesday to 1:00 AM EDT Thursday (02:00 to 05:00 UTC Thursday).
A first launch attempt on March 8 was scrubbed due to out-of-bounds propellant thermal conditions on the upper stage. During the second day of attempts on March 11, the countdown was aborted twice, first due to a stage separation automation issue at T- 0.5 seconds, then again due to low stage two fuel pressure.
