| Summary | Relativity Space's Falcon-9-class successor to Terran 1, partially 3D-printed, with 13 Aeon R methalox engines on a reusable first stage; second stage and fairing expendable. | NASA's human deep space launch vehicle for the Artemis programme. Uses heritage RS-25 shuttle main engines (4 per flight, expended). Block 1B with Exploration Upper Stage cancelled Feb 2026; Block 1 will fly through Artemis IV at minimum. | ULA's workhorse since 2002 and the longest-serving active US rocket. Launched Mars Science Laboratory (Curiosity), OSIRIS-REx, Solar Orbiter, Lucy, New Horizons, and the Boeing Starliner. Production ended in 2024 and ULA no longer sells the vehicle, but it continues flying a sold-out backlog of Starliner and Amazon Leo missions into the late 2020s. |
