Relativity Space is scheduled for the first launch of their Terran 1 rocket, called “GLHF” (Good Luck, Have Fun), from Launch Complex 16 at Cape Canaveral, Florida.
The launch window opens at 1:00 p.m., ET, on March 8, 2023. This launch of Terran 1 is the first orbital attempt by Relativity and will not include a customer payload.
As a two-stage, 110 ft. tall, 7.5 ft. wide, expendable rocket, Terran 1 is the largest 3D printed object to exist and to attempt orbital flight.
Working toward its goal of being 95% 3D printed, Relativity’s first Terran 1 vehicle is 85% 3D printed, by mass.
Terran 1 has nine Aeon engines on its first stage and a single Aeon Vac on the second stage.
Like its structure, all Relativity engines are 3D printed and use liquid oxygen (LOX) and liquid natural gas (LNG). These are the best mix for rocket propulsion as well as for reusability and the easiest to eventually transition to methane propulsion on Mars.
