| Summary | Firefly Aerospace's two-stage small-lift rocket powered by four Reaver engines at sea level and one Lightning engine in vacuum. Also provides launch services for NASA's CLPS programme (Blue Ghost lander launched on Falcon 9). FLTA007 'Stairway to Seven' succeeded Mar 11, 2026. | Germany's first orbital-class launcher attempt; its first flight in March 2025 was Western Europe's first orbital launch attempt from the European mainland. A qualification second flight carrying CubeSats and ESA experiments has slipped repeatedly through 2026. | 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. |
