Terran 1 is an expendable two-stage small-lift launch vehicle developed by Relativity Space since 2017. Unique to Relativity, most structures and components in the vehicle are manufactured with 3D printing processes. The first test launch was in March 2023 from Cape Canaveral. It passed max q and reached space but failed to achieve orbit due to a failure of the second stage.

The maximum payload was expected to be 1,250 kg (2,760 lb) to 185 km (115 mi) low Earth orbit (LEO). Relativity’s advertised launch price was $12 million USD per Terran 1 mission.

Terran 1 consists of two stages. The first stage is powered by nine Aeon 1 engines burning methane and oxygen propellants in a gas-generator cycle, each producing 100 kN (23,000 lbf) of thrust. The second stage is powered by a single vacuum-optimized version of Aeon 1, known as AeonVac, producing 126 kN (28,300 lbf) of thrust in vacuum. Both stages will be autogenously pressurized.

The payload fairing measures 6.8 m (22 ft) long and has a diameter of 3 m (9.8 ft). Terran 1 is capable of up to 1,500 kg (3,300 lb) to low Earth orbit. Relativity commonly states a payload capacity of 1,250 kg (2,760 lb) to lower inclination low-Earth orbits and 900 kg (2,000 lb) to a sun-synchronous orbit (SSO).

The primary and secondary structures of Terran 1 are manufactured with Relativity’s Stargate 3D printer out of a proprietary aluminum alloy. 90% of Terran 1 by mass consists of printed components; Relativity claims that they can reduce the part count in the vehicle by 100 times compared to traditionally-manufactured rockets and manufacture an entire flight article from raw materials in 60 days.  Relativity’s in-development Terran R launch vehicle will utilize the same tooling used to manufacture Terran 1.
