Expanding Access to Space
Terran R is a two-stage, reusable rocket built for today's satellites and tomorrow's breakthroughs. Perfectly sized to serve the Low Earth Orbit (LEO) constellation market, Terran R will make access to space more reliable and routine. Beyond LEO, we aim to empower science, exploration, and innovation across new frontiers.
