Throughout a 15-second take a look at flight, Stoke Area launched Hopper2 and landed the prototype higher stage in what’s a significant milestone within the firm’s plans to develop a completely reusable rocket.
The Seattle-based firm pulled off a vertical takeoff and touchdown of its launch car on Sunday at its take a look at web site in Moses Lake, Washington, Stoke Area announced. Hopper2 launched to an altitude of 30 ft (9 meters) and touched down inside its deliberate touchdown zone following 15 seconds of flight.
“This take a look at was the final take a look at in our Hopper know-how demonstration program,” Stoke Area wrote in its assertion. “We’ve obtained an unbelievable quantity of information that may allow us to confidently evolve the car design from a know-how demonstrator to a dependable reusable house car.”

Final week, Stoke Area ran a static engine firing take a look at for Hopper2, which adopted testing of an earlier prototype, Hopper1, within the spring. The corporate has got down to create a completely reusable launch car, which is but to be achieved within the trade. SpaceX’s Falcon 9 is partially reusable with all however the second stage that may be recovered and reused.
With Hopper2, nevertheless, Stoke Area desires its second stage to ship its payload to orbit to orbit and make its means again for a vertical touchdown on Earth, earlier than which it must survive the acute temperatures of atmospheric reentry. Hopper2 is designed with a regeneratively cooled warmth protect, with small cavities lined throughout its outer layer so propellant can circulate via the fabric to maintain it cool throughout reentry via Earth’s ambiance.
Following Sunday’s take a look at flight, Stoke Area is now going to give attention to its reusable first stage. “With our revolutionary second stage design, our workforce at Stoke is trying to do one thing that has by no means been carried out earlier than: design and construct a rocket that’s 100% reusable with a 24-hour turnaround,” the corporate wrote. “To achieve that aim, we are going to now proceed transferring via our growth program by rising give attention to our reusable first stage.”
