Good Luck, Have Fun (Terran 1)
22 March 2023
Space Launch Complex 16
Cape Canaveral Space Force Station
The world's first 3-D printed rocket lifted off on its inaugural flight at 11:25 p.m. on 22 March 2023 from Space Launch Complex 16 at Cape Canaveral Space Force Station. Fueled by liquid methane and liquid oxygen, Relativity Space's Terran 1 rocket flew nominally through stage separation when the second stage engine suffered an anomaly causing the second stage to fail to reach orbit. The rocket was not carrying a payload; the flight test was designed to collect as much data as possible on the vehicle's performance.
ON-PAD ABORT - 11 MARCH 2023
The first Terran 1 launch attempt at 2:42 p.m. on 11 March 2023 ended in an on-pad abort when the engines ignited and then shutdown. Relativity Space stated that a problem was detected in the stage separation automation that resulted in the abort at T-.5 seconds. A second attempt at 4:00 p.m. led to a scrub at T-45 seconds when low fuel pressure was registered in the second stage.
LAUNCH - 20 MARCH 2023

EXCERPTS FROM RELATIVITY SPACE MEDIA RELEASES

As a next generation launch vehicle, Terran 1 is designed for the future of constellation deployment and resupply. Its ground-breaking, unique and software-driven architecture is capable of accommodating satellite customers’ evolving needs, while also providing the most agile and affordable launch service on the market. Designed and printed in the USA, Terran 1 is the most innovative product to emerge from the aerospace manufacturing industry since the dawn of privatization of space 20 years ago.

Our engines, Aeon 1, Aeon R and Aeon Vac, are 3D-printed, enhancing mission reliability by reducing part count in engine combustion chambers, igniters, turbopumps, reaction control thrusters, and vehicle pressurization systems.

All Aeon engines use propellants of the future, liquid oxygen + liquid natural gas, which are not only the best for rocket propulsion, but also the easiest to eventually make on Mars. To date, Aeon has completed 2,000+ test fires.
