Stoke Space Secures $860M in Extended Series D Funding for Reusable Nova Rockets

Big news from the space world: Stoke Space just pumped up its latest funding round to a whopping $860 million. This extension of their Series D comes right after they announced $510 million back in early February 2026, showing investors are all in on their dream of fully reusable rockets.

The cash will help them ramp up making the Nova rocket and get Launch Complex 14 ready at Cape Canaveral. It’s a huge step for a company that’s been pushing boundaries since day one.

Meet the Founders Behind the Magic

Stoke Space kicked off in late 2019, thanks to two sharp minds from Blue Origin: Andy Lapsa and Tom Feldman. Andy, now CEO, spent years leading engine projects like the BE-3 and BE-4. Tom, the CTO, tackled tough parts like the oxidizer pump on the BE-4.

These guys didn’t just dream big—they jumped in with both feet. Andy has a PhD from the University of Michigan, and Tom studied at Purdue. They saw a gap in space tech: rockets that could fly over and over, like planes, without breaking the bank. Their bet? Build from scratch with speed and smarts.

What sets them apart is their hands-on style. They hire top talent, give them real ownership, and celebrate quick wins. No wonder big names like Breakthrough Energy Ventures keep backing them.

What Makes Nova a Game-Changer

Nova is Stoke’s star: a two-stage rocket built for full reusability from top to bottom. The second stage packs an Altair engine running on liquid hydrogen and oxygen (LH2/LOX). It hits over 425 seconds of specific impulse—that’s a key measure of how efficiently it uses fuel—and pumps out 25,000+ pounds of thrust.

This engine isn’t just powerful; it’s tough. It doubles as an actively cooled metallic heat shield for reentry. Picture this: the rocket screams back from orbit, slows using air drag to under 100 meters per second, then fires up for a pinpoint vertical landing. No parachutes, no ocean dips—just ready for the next flight.

The first stage uses a full-flow staged combustion engine with LNG and LOX, delivering 100,000+ pounds of thrust at 345 seconds Isp. Payload? Up to 7,000 kg to low Earth orbit if expendable, or 3,000 kg fully reusable. It can even haul 2,500 kg to geostationary transfer orbit or 1,250 kg toward the Moon.

Stoke calls this “Reusability 2.0.” Low ballistic coefficient means gentler reentries, and cross-range steering gets it home precisely. They’re aiming for aircraft-like turnaround times.

The Funding Journey So Far

This $860 million isn’t starting from zero. Stoke first grabbed $65 million in Series A from Bill Gates’ Breakthrough Energy Ventures. Series C brought $260 million more in late 2024 or early 2025, with players like Glade Brook Capital and Y Combinator joining in.

Now, with Series D extended, total funding tops $1.34 billion. That’s serious muscle for scaling factories, testing, and hitting orbital flights. They’re eyeing a first Nova test in 2025, but this cash pushes them faster toward real launches.

Investors love it because space needs cheaper rides. Satellites, cargo, even crew—Nova could slash costs with rapid reuse.

Why This Matters for Space's Future

Reusable rockets aren’t new—SpaceX proved partial reuse works. But Stoke goes all-in: both stages land and refly, no exceptions. Their metallic heat shield survives high-energy reentries, landing on rough spots if needed.

Downmass capability means grabbing stuff from orbit and bringing it back—like space junk or experiments. That’s huge for science and logistics.

Stoke is building a 21,000-square-foot facility and test sites. They’ve nailed milestones, like second-stage prototypes, and keep iterating fast.

With $860 million in the bank, expect factory growth and more hot-fire tests. Launch Complex 14 at the Cape will host Nova’s debut, putting Florida on the map for reusable tech.

Co-founders Andy and Tom keep the pedal down. They’ve hit engine tests and prototypes ahead of schedule. Orbital flight? They’re gunning for it soon, maybe riding 2025 momentum into 2026.

Stoke isn’t alone, SpaceX, Blue Origin compete—but their full-reuse focus and ring of fire engine protection could carve a niche. Watch for partnerships with satellite firms hungry for cheap launches.
