The Terran-1 is a planned small launch vehicle by Relativity Space, which will be built mostly by 3D printing.

Relativity Space plans to build a Terran-1 rocket in only 60 days from raw materials by 3D printing the structure, payload fairing as well as the engines.

The first stage is powered by 9 Aeon-1 engines, fueled by liquid oxygen (LOX) and methane. After the third flight, a single Aeon-R, developed for the larger reusable Terran-R, will replace the 9 Aeon-1 engines.

Stage 2 is powered by a single restartable Aeon-1 Vacuum engine. Terran-1 will have a payload of 1250 kg to a 185 km low earth orbit and 900 kg to a 500 km sun synchroneous orbit.

Relativity Space has leased Launch Complex 16 at Cape Canaveral from the US Air Force. The first test launch is planned for late 2021. Another launch pad will be built at Vandenberg at the site of Building 330, likely to be named SLC-7.
