Stoke Space Technologies is an American space launch company based in the Seattle suburb of Kent, Washington.

History

The company was founded by a group of former Blue Origin and SpaceX employees.[1]

In May 2020, the company won a $225,000 SBIR Phase I grant from the National Science Foundation to work on an integrated propulsion solution for reusable rocket upper stages.[2]

In February 2021, the company raised $9.1 million in seed funding in a round led by venture funds NFX and MaC Venture Capital.[1]

In December 2021, the company raised $65 million in a Series A round led by Breakthrough Energy Ventures,[3] funding development and testing of the upper stage of a reusable launch vehicle.[4]

In 2021, not much was publicly known about the testing and development of Stoke Space's technologies.[citation needed] In 2022, the company created a prototype of their second stage engine ring. Their prototype had at least 22 static fires in total. In 2023, Stoke Space had an interview with Tim Dodd (also known as The Everyday Astronaut), wherein the CEO Andy Lapsa revealed their plan to create a fully and rapidly reusable orbital rocket.[5]

In the first months of 2023, Stoke Space finished the construction of Hopper1, a full-scale second stage prototype, intended perform "hop" tests similar to SpaceX's Starhopper Prototype.[citation needed]

On March 8, 2023, the company was given LC-14 in Florida as a future launch pad for their vehicles.[6] On March 18, Stoke Space's second stage conducted a Wet Dress Rehearsal, where the company loaded both Liquid Oxygen (LOX) and Liquid Hydrogen into the stage's tanks, preparing it for launch without igniting the engines.[citation needed]

On September 17, 2023, Stoke Space conducted a 10 meter "hop" test of "Hopper2", testing their unique differential steering method. In 15 seconds, the vehicle ignited its 15 thrust chambers (half of the amount used on the operational vehicle), lifted 30 feet off the ground, showed its ability to steer without gimballing the engine like traditional rockets, and tested the actively cooled heatshield before successfully landing under three landing struts.[7]

In October 2023, Stoke Space announced a $100 million Series B funding round led by Industrious Ventures.[8]

Facilities

The company operates a rocket test facility on a 75-acre (30 ha) site near Moses Lake's airport.[9]

Technology

Stoke Space is developing a fully and rapidly reusable space launch vehicle called Nova,[10] and is focusing on its second stage.

Stoke Space's reusable second-stage uses a single engine with 30 thrust chambers around the circumference of the vehicle, along with a center passive bleed to create an aerospike engine-like effect. Additionally, the center bleed acts as a heat shield during re-entry, eliminating the need for brittle ceramic tiles that have required detailed inspections and lengthy refurbishments on other space vehicles,[11][12] like the Space Shuttle orbiter.

For its reusable first stage, the company is considering 7 conventional full-flow-staged combustion rocket engines, burning methalox. This configuration is very similar to SpaceX's Raptor Engine.[13][14]
