Redefining space mobility at the edge
Affordable, sovereign satellites in Very Low Earth Orbit owned outright, launched from almost anywhere, and operated by you!
Why STARS EDGE
Welcome to Stars Edge
Stars Edge is on a mission to make space affordable, sovereign and genuinely usable. We build the next generation of satellites for Very Low Earth Orbit (VLEO), flying at just 100-150 km, the lowest sustained orbit there is.
At that altitude, atmospheric drag stops any conventional satellite. Our proprietary AERIS engine turns that problem into the solution: it breathes the thin upper atmosphere and uses it as propellant, so our satellites stay in flight without carrying fuel to fight the drag.
Flying this low changes everything. Far lower radiation means we use commercial, off-the-shelf electronics and lighter, more sustainable materials instead of expensive rad-hardened parts, cutting build and operating costs dramatically. A shorter link to the ground means more data down, lower latency and true direct-to-device connectivity. And a closer view means spy-level image resolution from a fraction of the altitude of LEO.
The result is a satellite you can own and operate yourself; not rent, and not queue behind someone else's constellation. Why rent a satellite, or its data, when you can own the whole stack?
What is VLEO?
Very Low Earth Orbit (VLEO) is the band of space below roughly 450 km ...well beneath the 500- 1,500 km where today's constellations fly. Stars Edge operates at the extreme low end of it, 100–150 km, closer to Earth than any sustained satellite before it.
The closer you fly, the better the physics: smaller optics reach sub-metre ground resolution, launch mass and power drop, orbital periods shorten for more frequent revisits (up to 17 passes a day), and the radiation environment is mild enough for modern commercial electronics and on-board AI. The only catch is atmospheric drag and AERIS is built to use it, not fight it.
AirSAT. Space but Closer
AirSAT is the lowest-flying Earth observer ever built, so close it barely looks like space. It is a payload-agnostic platform, mass-manufacturable on a sovereign supply chain and priced to be bought, not rented.
Because it flies at 100-150 km, AirSAT captures sub-metre imagery with breakthrough clarity and speed, and revisits the areas you care about up to 17 times a day. Whether you are tracking wildfires, mapping urban heat, monitoring crops or watching a coastline, AirSAT brings precision data close to home and gets the answers to you faster.
You fly it with a laptop, not an ops centre.
AirSAT is built for genuine self-operation. Our proprietary direct-to-device (D2D) comms and on-board edge computing remove the entire ground segment between you and your satellite: task it from your own device, uplink on the next pass, let it process the raw data in orbit, and receive a finished answer on your screen, not terabytes to sift.
The result is near-zero operating effort and full sovereign control, extended time in VLEO, high-speed downlink, low latency, and D2D architectures that reach the most remote regions on Earth.
