| Summary | 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. | The next evolution of ESA's Vega line: replaces the Zefiro-9 and AVUM+ stages with a single cryogenic LOX/methane upper stage powered by the new M10 engine, adding multi-orbit deployment flexibility. First flight is a stated target (2027), not yet flown. | China's most-used sun-synchronous and polar orbit workhorse for small-to-medium military and commercial Earth observation satellites. Launched from Jiuquan and Taiyuan. Uses storable hypergolic propellants for high launch-readiness but produces toxic exhaust. |
