Exclusive: DoD Taps Orbital Operations for Cryogenic Spacecraft Demo

For decades, the Lockheed C-130 Hercules aircraft and variants have hauled cargo, flown as gunships, and refueled military jets midair. Now, Orbital Operations wants to do the same in space.

The Long Beach, CA, startup has won up to $35M from the DoD under a prototype Other Transaction Agreement to fly a full-scale, in-orbit demo of Astraeus—its cryogenic-maneuvering vehicle.

The company also closed a $7M seed extension led by DTX Ventures, bringing its total raised to ~$16M. GoAhead Ventures and Solaris Ventures also participated alongside follow-on investment from Initialized Capital, Harpoon Ventures, TRAC VC, and others. 

“Space is now a contested environment,” Orbital Operations CEO and cofounder Ben Schleuniger told Payload. “We’re going into this new space age where there’s all these new orbits and all of these new ideas coming around…we just need more dynamic assets out there to transport things around.” 

Meet Astraeus: The vehicle is designed to bring launch-vehicle-class propulsion to on-orbit operations. 

  • An onboard refrigeration system is designed to keep Astraeus’ liquid hydrogen and oxygen from boiling off, with the goal of keeping the vehicle on-orbit for years—much longer than the week or so that a disposable stage lasts.
  • The company is aiming to be able to carry out maneuvers within single-digit hours of giving a command, well inside the 48-hour window Schleuniger said military operators want.
  • After ferrying payloads to higher orbits, Astraeus is built to return to LEO to refuel.
  • The same base vehicle can be fitted for logistics, tactical, or refueling missions, mirroring the C-130’s mission-dependent variants.

“In a sense, we’re looking to be that reusable third stage,” Schleuniger said, adding, “It’s very dual use, but it also unlocks just all dynamic operations out in orbit—not just range, but speed.”

Cosmic timing: Schleuniger didn’t have to look far for an example of why the Pentagon wants these capabilities. Over the past week, Russia’s Cosmos 2612 shadowed ICEYE-X36, a US-flagged radar sat widely believed to supply imagery to Ukraine. LeoLabs tracked the Russian spacecraft closing to ~500 m between Oct. 15 and 19, before it drifted away. 

Still, Schleuniger said demand was already high “even before we had the incident this last week.” He pointed to SPACECOM’s list of tech priorities for 2029 to 2033, which names sustained space maneuver as one of its top needs. 

Later stage: The ~13-person team went from closing its seed round to a full-pressure hot-fire in under six months. Next up are more engine hot-fires, refrigeration-cycle work, and qualification before flight.

More fundraising is likely, but the government award “is really to get us to that first flight,” Schleuniger said.
