About Radian Aerospace
Radian Aerospace is developing Radian One, a horizontal takeoff/landing single-stage-to-orbit spaceplane—the 'holy grail' of space transportation. The vehicle will launch from a 3+ kilometer rocket-powered rail sled, reaching orbit with rocket engines before runway landing, capable of flying again in 48 hours. Radian One will carry five people and 2,270 kg cargo to LEO. In April 2025, the company unveiled the R3V (Radian Reusable Reentry Vehicle) platform for near-term revenue generation. Radian partnered with General Atomics in March 2025 for advanced avionics. The company's ambitious SSTO design could revolutionize space access if successful.
