Observable Space raises $90M Series A to scale laser satellite communications
What's the deal? Observable Space, a startup based in Adrian, Michigan, has raised $90 million in its debut funding round to develop laser-based communications between satellites — and potentially orbiting data centres — and Earth.

Alongside the raise, the company announced a $94 million contract with the US Space Force to expand its fleet of ground-based optical telescopes that track satellites for the Pentagon.
Why now? The dual announcement — venture funding plus a major defence contract — signals growing urgency around space communications infrastructure. As satellite constellations multiply and the concept of orbital data centres gains traction, demand for high-bandwidth links between space and ground is accelerating. The US military's willingness to invest $94 million in Observable Space's telescope network reflects a broader push by the Pentagon and allied nations to bolster space domain awareness.
What could go wrong? Laser-based optical communications remain technically challenging. Weather, atmospheric interference, and the sheer precision required to aim a laser beam across hundreds of kilometres of space all pose engineering hurdles. The company is also early-stage — this was its first funding round — and heavy reliance on a single government contract introduces concentration risk.
The signal: A $90 million debut round is unusually large for an early-growth company, reflecting how quickly investor appetite for space-infrastructure plays has matured — particularly when a startup can pair venture backing with immediate government revenue. Lux Capital's lead role fits its established thesis of funding deep-tech at the frontier, while RTX Ventures' co-lead suggests incumbent defence primes see laser-optical comms as a capability they would rather back than build in-house.
