Stoke Space raises $9.1 million for rocket reusability

Stoke Space Technologies, the Renton, Wash.-based company founded by veterans of Jeff Bezos’ Blue Origin space venture, has attracted $9.1 million in seed investments for extending rocket reusability to new frontiers.

The first goal will be to develop a new kind of reusable upper stage, Stoke co-founder and CEO Andy Lapsa said. “That’s the last domino to fall in the industry before reusability is commonplace,” Lapsa told GeekWire. “Even right now, I think space launch is in a production-limited paradigm.”

Rocket reusability is the watchword, to be sure — not only at Blue Origin, where Lapsa was an award-winning rocket engineer, but also at SpaceX and other leading launch companies.

Both Bezos and SpaceX CEO Elon Musk have said total reusability is the key to driving down the cost of access to space, and opening up new frontiers including regular runs to Mars and back. Until recently, however, the focus has been on reusing a rocket’s first-stage booster. The upper stage — which kicks in after the first stage is exhausted to push payloads the rest of the way to orbit — typically burns up during atmospheric re-entry at the end of its flight.

SpaceX is aiming to change that paradigm with its Starship super-rocket. The massive prototypes that are currently being tested at that company’s South Texas launch facility are part of a development effort for reusable second stages that would sit on top of an even more massive Super Heavy booster — and fly themselves back to a landing pad after they’ve done their job.

Lapsa said what SpaceX is doing with Starship is “incredible.”

“But I think that same type of mentality needs to be applied to the commercial satellite market, in order to really provide them with what they’re looking for,” he added. “So that’s where we’re starting.”
