| Summary | ULA's workhorse from 2002–2024. Launched Mars Science Laboratory (Curiosity), OSIRIS-REx, Solar Orbiter, Lucy, New Horizons, and the Boeing Starliner. Its Russian RD-180 first-stage engine became a political liability after 2022; last flight was the Amazon Kuiper testbed on Apr 9, 2024. | The world's most commercially active small launch vehicle, designed and built in-house at Rocket Lab. Rutherford engines are the first flight-proven engines made with additive manufacturing (metal 3D printing). Booster recovery via parachute and helicopter catch (later transitioned to ocean recovery). | 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. |
