Default Terran 1: Launching The World’s First 3D Printed Rocket - 11 Mar 1300-1600 ET

If successful will be the first methane fueled rocket to reach orbit. Live stream:

Terran 1: Launching The World’s First 3D Printed Rocket - 11 Mar 1300-1600 ET

Relativity is scheduled for its second launch attempt of Terran 1, called "GLHF" (Good Luck, Have Fun), from Launch Complex 16 in Cape Canaveral, Florida. Our launch window opens at 1300ET on March 11, 2023. This launch of Terran 1 will not include a customer payload.

Standing 110 ft. tall and 7.5 ft. wide, Terran 1 is the largest 3D printed object to attempt orbital flight. As a two-stage, expendable rocket, Terran 1 has nine 3D printed Aeon engines on its first stage and one Aeon Vac on its second stage.

Like its structure, all Relativity engines are entirely 3D printed, and use liquid oxygen (LOX) and liquid natural gas (LNG), which are not only the best for rocket propulsion, but also for reusability, and the easiest to eventually transition to methane on Mars.

Between high level winds causing delays and some idiot(s) in a boat wandering into the exclusion zone, the second abort put them past their 4 hour window.

During abort #1: It was a corner case in the stage separation automation a few seconds before T-0 that properly aborted at T .5 seconds.

Then, the team pushed an update to the vehicle automation, successfully recycled the vehicle, and secured a new T-0 time, which was an instantaneous window, given it was during the last minute of our launch window today at 16:00 ET.

During abort #2: At T-45 seconds, we had an automated abort on stage 2 fuel pressure, which was only one PSI low.

Pretty impressive despite the second stage fail.

Thanks for posting this Winston... I guess maybe that 3d printing witchcraft is a viable option afterall.
