Orbital Matter and EnduroSat Partner for In-Space Solar Array Manufacturing

The expanse of space demands self-sufficiency. Building large structures off-world, rather than launching them fully formed, shifts the calculus of orbital development.

Orbital Matter, a company specializing in in-space manufacturing, has announced a partnership with satellite developer EnduroSat. Their joint mission, slated for 2028, will demonstrate the on-orbit assembly of a significant power source.

The core of the mission involves deploying a 5-kilowatt solar array. This will be achieved through Orbital Matter's proprietary 3D printing capabilities, fabricating components directly in the vacuum of space.

Orbital Matter will "deploy a 5 kW solar array with its 3D printing capabilities," the original report stated.

Current space infrastructure often relies on compact, deployable designs that fit within rocket fairings. In-space manufacturing bypasses these volumetric constraints, enabling the construction of structures far larger than any single launch vehicle could carry.

This approach promises to reduce the mass and complexity of components needing to survive launch forces. Instead of rigid, heavy panels, raw materials or simpler modules can be sent up, then assembled or printed on site, potentially lowering overall mission costs and increasing resilience.

For future inhabitants of orbital habitats or lunar outposts, this technology means greater autonomy. The ability to print a new solar panel, a structural beam, or even a replacement part for a life support system without waiting for an Earth-launched resupply fundamentally changes the logistics and economics of permanent off-world presence. It moves beyond mere maintenance to genuine self-extension.
