Stoke Space has announced the first successful hot-fire test of an engine designed for its upcoming reusable rocket.
The Kent, Washington-based company tested its new full-flow, staged-combustion (FFSC) rocket engine on June 5 at the company's test site in Moses Lake, Washington. Photos from the test show the engine kicking up a large plume of sand and rocks as the engine was throttled up to produce half of its maximum thrust.
