Leak shroud testing – the six-sided metal enclosure around the nozzle is designed to simulate the engine bay of the integrated rocket to identify any fuel or oxidizer leaks during a full mission duty cycle burn. This is a key test to help retire risk for stage static fire and
@ScottRheeder @stoke_space @Rkt_Da When it’s ready :) We’re working hard and want it as much as anyone!
Super proud of the team for this one. BIG step!
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
Engines racking up time on both test cells. Vehicle turned on and about to start testing...things are happening!
Testing is LIVE in Moses Lake, for both our Stage 1 structure and Zenith engines. Proud of the teams who are working relentlessly to drive us forward on the road to launch.🛣️🚀
From factory floor to installed on stand in less than 18 hours - not bad for SN1!
Our Stage 1 structure is now shipped, delivered, and ready for testing in Moses Lake, WA. Standing in its full vertical orientation, this flight hardware will be thoroughly vetted before returning to Kent for some final touches before the journey to Cape Canaveral, FL begins.
Incredible work by our small but mighty team of structures engineers and fabricators. Can’t wait to see this thing go vertical!
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!
Checkin off objectives
Another day, another Zenith engine hot fire... Here we conduct a chirp test of our thrust vector control system - gimbaling the engine at increasing frequency to demonstrate control bandwidth (how fast we can respond to commands in flight). 📈
It’s great to see our nation’s space program returning to a culture of pragmatism and results under @rookisaacman. Under that context, congrats to @SenateCommerce and @commercedems for advancing the NASA Reauthorization Act of 2026. This bill puts NASA on a path to unlock the LEO economy with scalable transportation to, through, and from space, advancing America’s leadership in the developing space economy.
it's an honor and a privilege to carry this historic pad into the future. lfg! 🇺🇸🇺🇸🇺🇸
Today, on the anniversary of John Glenn's historic space flight in 1962, we raised the flag over SLC-14 for the first time since breaking ground. It's an honor to be part of America's space history – and its future. 🇺🇸🚀 Special thanks to @SLDelta45 installation commander

Happy to announce an extension of our Series D financing round to $860M, adding $350M to the initial $510M raised in October 2025. This brings our total funds raised to $1.34B. We're grateful to our investors and excited to bring our fully and rapidly reusable Nova rocket to
5 yrs since YC but feels like 20 (and also feels like yesterday). Fun retelling those earliest days but it's still day 1 for us and for space, and there's a LOT more to do!
Stoke Space is racing to build the world's first fully reusable rockets that can launch, survive reentry, and fly again almost right away. In this episode of Hard Tech, @aaron_epstein sits down with @stoke_space co-founders @AndyLapsa and @Rkt_Da to find out why they chose to
@MattGialich @SciGuySpace @stoke_space I'm partial to BiggererNova_v3_final_final_DONE
@SciGuySpace’s work is always no BS and heavily researched. In fact we give a copy of his book Liftoff to every new hire so it was an honor to spend some time with him at SLC-14 and share the progress.
I recently visited Stoke Space's launch site in Florida to understand what they're up to, and whether they can realize their grand ambitions. arstechnica.com/space/2025/11/…
Congrats to everyone at Blue for an incredible flight. Those engines...all the feels 🥰
It was less than 10 years ago when the idea of recovering a 1st stage was extremely controversial. Now it's absurd to even consider anything else. Today, the same skepticism surrounds 2nd stage reuse, but it won't be long until that, too, is archaic.
