Relativity Space has just revealed what comes after Terran 1, the small launch vehicle it hopes to begin flying later this year. It’s next rocket will be Terran R, a much larger orbital rocket with around 20x the cargo capacity of Terran 1, that will also be distinguished from its smaller, disposable sibling by being fully reusable — across both first and second stages, unlike SpaceX’s Falcon 9. I spoke to Relativity Space CEO and founder Tim Ellis about Terran R, and how long it’s been in the works for the space startup.
