About
Terran R is Relativity Space’s second-generation orbital launch vehicle and a major leap in ambition from the retired Terran 1. Where Terran 1 was an expendable small launcher (1,250 kg to LEO, retired after its first flight attempt in March 2023), Terran R is a two-stage reusable rocket that Relativity rates at 23,500 kg to low Earth orbit with a downrange landing, 33,500 kg in expendable configuration and 5,500 kg to GTO.
Terran R uses Relativity’s Aeon R engines (a closed-cycle derivative of the Aeon 1 that powered Terran 1), burns LOX/liquid methane, and is built from cost-effective, high-strength aluminium alloys.
The vehicle is designed to be competitive with SpaceX Falcon 9 reusable by targeting similar payload class with reusability from the start. Relativity pivoted its entire focus to Terran R in mid-2023 following the Terran 1 program conclusion. Relativity plans to fly Terran R from Launch Complex 16 at Cape Canaveral starting in late 2026.
