CAPE CANAVERAL, Florida – The launch of the world’s first 3D printed rocket that was set liftoff from Launch Complex 16 in Cape Canaveral, Florida at 1 p.m. Eastern Time on Saturday, March 11, 2023 was scrubbed after repeated aborts by mission control.

Relativity Space’s first launch of Terran 1, called “GLHF” (Good Luck, Have Fun), is the first orbital attempt by Relativity Space and will not include a customer payload.

Relativity scrubbed the launch on March 8 due to exceeding launch commit criteria limits for propellant thermal conditions on stage 2.

Launch Weather 90% ‘GO’

As a two-stage, 110ft. tall, 7.5 ft. wide, expendable rocket, Terran 1 is the largest 3D printed object to exist and to attempt orbital flight.

Relativity’s first Terran 1 vehicle is 85% 3D printed by mass but the company’s goal is to ultimately reach 95% 3D printed.

Terran 1 has nine Aeon engines in its first stage, and one Aeon Vac in its second stage.

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