Relativity Space - GLHF
On March 22, 2023, Terran 1 became the first 3D printed rocket to reach space. This maiden voyage, dubbed our ‘Good Luck, Have Fun’ (GLHF) campaign, proved that large-scale 3D printed objects are flight-worthy, even in dynamic environments. Measuring in at 110 feet tall and 7.5 feet wide, Terran 1 was the largest 3D printed object to exist – not to mention attempt orbital flight. The vehicle was 85% 3D printed by mass, with nine Aeon 1 engines on its first stage and one Aeon Vac on its second stage. Liquid oxygen (LOX) and liquid natural gas (LNG) were used as propellants, since they enable efficiency and high-rate reusability. First methane fueled rocket in the West to reach space, past the 100km Karman Line. First 3D printed rocket to fly and pass Max-Q, the point of maximum stress on the rocket. First methane orbital-class rocket to successfully complete stage 1 flight, main engine cutoff, and second stage separation in the West. First-ever second stage ignition attempt during the v
