Stage 2 has officially left the rocket factory for the last time. 😢🫡 Now in Moses Lake, WA, it will undergo cryo proof testing and then a hotfire campaign with its Andromeda engine before shipment to our launch site in Cape Canaveral, FL.

Autonomy-1 will take the next step. Flying on Stoke's Nova Pathfinder, Autonomy-1 will attempt to complete every mission objective without a command from Earth, while carrying a real NASA Goddard heliophysics payload. The future of deep space is autonomous. Introducing Solo + Autonomy-1: astroforge.com/updates-colle…

With our Nova Pathfinder launch vehicle well under way, it’s time to share more about Nova Block 2, the larger configuration our team has been developing in parallel. Get the details in our blog post, “Scaling Nova”: stokespace.com/news/scaling-…

Scaling Nova

Seamless mobility to, through, and from space. Nova is built for 100% reusability, from the start.

Got a lot of work cut out for us, but this is a nice start

Today, Stoke announced a $1 billion Series E, bringing our total capital raised to $2.3 billion. This funding will help us bring Nova Pathfinder to flight, accelerate development of our larger 15-ton-class Nova Block 2 vehicle, and build the production capacity required to fly at scale. This milestone reflects years of extraordinary work by the Stoke team and the conviction of customers and investors who share our belief that fully reusable space transportation is both possible and necessary. We are deeply grateful for their trust, and more energized than ever by the work ahead. Read the full announcement: stokespace.com/news/stoke-sp…

We recently mated the payload module, second stage, and Andromeda engine at our rocket factory in Kent, WA. Fit check, check. ✅

The first three of our flight one engines are designed, built, and ready for testing. ✅ Stage 1 Zenith engines ZE14, 15, and 16 are ready to ship from our shop floor in Kent, WA to Moses Lake for hot fire acceptance testing. Getting our Zenith engines through qualification testing is no small feat, and trusted vendors like Performance Sealing Inc. - who can iterate at industry-leading speeds - are key to keeping our work on time and on track.🙏🙌

Big tank. Big tests. Big milestone. Nova Stage 1 proto-qualification is complete. 46 structural objectives verified, plus key fluid systems, avionics, software, ground systems, and ops demos. (More detail in our linked blog post.) This is where new rockets often find the hard stuff; Nova (and the Stoke team) handled it. Our local partners at the @PORTOFMOSESLAKE , the Grant County Sheriff's Office and Public Works department, plus our vendor Norco made sure we had the support we needed every step of the way.

Sneak peek inside our Stage 1 tank, putting the finishing touches on our integration campaign.🤩 Next week, this flight article will ship to our test site in Moses Lake, WA for protoqualification testing. Enjoying the views at Kent while it lasts!

Testing update! Overall solid day with lots of good things and some not great things: - DAQ and test stand functioning well - pump hit speed record at 4000 rpm - hit 100 psi of head rise for 2 seconds before seizing (FOD) - pump is cleaned and ready for more testing this week!

First trim test of our Zenith ZE12 engine to assess the flight thrust chamber assembly's (TCA) design performance and to run the engine system through its range of power levels and mixture ratios–along with performance upgrades to our fuel turbopump 🧑‍🍳😙🤌 (Also shows performance upgrades to our fuel turbopump.)
