Stoke Space Scores a Success In First Test Firing of Engine For Reusable Nova Booster

Kent, Wash.-based Stoke Space successfully completed the first hot-fire test of its reusable Nova launch vehicle's first-stage engine, which reached 350,000 hp in under a second during a two-second test on June 5. GeekWire reports: During the two-second test, the engine ramped up to its target starting power level, producing the equivalent of 350,000 hp in less than a second, and held that power level until shutdown. At full power, the full-flow staged combustion engine is designed to produce over 100,000 pounds of thrust. The rocket engine was designed and manufactured in just 18 months. The medium-lift Nova rocket's first-stage booster will be powered by seven of the engines. Stoke successfully conducted a vertical-takeoff-and-landing test flight of its reusable second stage last September. Since then, the company has been focusing on first-stage development. For the rest of this year, Stoke expects to continue maturing its engine and vehicle design while scaling operations for orbital launch. Stoke Space said last year that it was targeting 2025 for its first orbital test flight -- but that timetable depends on progress in the development program.
