| 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. | A liquid-biomethane orbital smallsat launcher from Interstellar Technologies, Japan's most established private rocket startup by suborbital flight heritage, though not yet flown to orbit. | 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. |
