Vaelon Space
Vaelon keeps autonomous spacecraft operating within mission intent, so operators can trust what they do without watching every decision.
Why it matters
More spacecraft are making more decisions on their own, with less time for anyone to check them.

How it works
Between the plan and the spacecraft, Vaelon lets safe actions through and turns unsafe ones aside.
Who it’s for
Inspecting, repairing or refuelling another spacecraft means flying very close to it, often with software making the final calls. A wrong move is costly and cannot be undone.
Vaelon checks every proposed move against fixed safety rules first. Anything that would take the spacecraft too close is held back and replaced with a safer move.
As fleets grow, no team can review every decision by hand. Operators want the satellites to act on their own, but need to know the limits will hold.
Vaelon sits on each satellite as a quiet second opinion. Routine actions pass straight through. The rare unsafe one is stopped, and the reason is recorded for the team.
Teams building autonomous spacecraft, and the agencies and insurers behind them, are asked the same question: how do you know it will stay within its limits?
Vaelon gives them an independent layer with a permanent record of every decision. Something concrete to point to, kept separate from the autonomy it watches.
The journey
Each step is earned before the next begins. We mark honestly where we are.
The check that sits between a spacecraft's decisions and its hardware exists, works, and has been proven on the ground.
We ran it against real, public information about objects passing close to each other in orbit, and kept an honest record of what it did.
We are working with an early partner so Vaelon can be tried on their own mission data. Nothing on their spacecraft is touched.
Moving from software on a desk to the kind of computer that actually flies, and showing it behaves the same way.
Independent specialists check our work against space industry safety standards, so trust does not rest on our word alone.

Partners and investors
Vaelon is early and honest about it. The most useful thing right now is people who will test it against the real world.
You share a record of a mission, real or simulated. We show you what Vaelon would have caught. It runs alongside, nothing on your spacecraft changes, and it can take as little as an afternoon.
