Launched in March 2023, Terran 1 was our first pathfinder vehicle – a two-stage, small-lift rocket that is now retired.

Terran 1 demonstrated our ability to simultaneously develop novel technologies while planning, designing, testing, and operating an orbital-class launch vehicle. Building on this foundation, we are now focused on Terran R, our medium-to-heavy lift reusable rocket. Key engineering learnings from the Terran 1 program – including LOX-methane propulsion systems, gas generator combustion cycle, guidance, navigation, and control algorithms, in-house developed flight software, structural dynamics, and aerothermodynamics – are directly relevant to the Terran R vehicle.

Terran 1 Highlights

• First methane-fueled rocket in the West to reach space, past the 100 km 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.
