Terran R is a medium-lift two-stage, fully reusable launch vehicle under development by Relativity Space. The vehicle is primarily constructed with 3D printing technologies, much like its predecessor, the small-lift Terran 1.^[1]

Description

Terran R is an evolution of the Terran 1, with a maximum payload capacity of 20,000 kg (44,000 lb) to low Earth orbit. The first stage will use seven Aeon R engines, producing an estimated thrust of 1.33 MN (300,000 lbs) each.^[2] The second stage will use an upgraded Aeon 1 engine with a copper chamber. With this design, Relativity is aiming to exceed the Falcon 9 payload to low-Earth orbit by approximately 20 percent, with a target payload mass as of June 2021^[update] of approximately 20 tonnes (44,000 lb). Relativity Space CEO Tim Ellis has compared the design of Terran R to SpaceX's Starship vehicle.^[3] In July 2022, Relativity announced it partnered with Impulse Space to send a payload to Mars in 2025.^[4]
