Astroscale Unveils Innovative Approach to Satellite Refueling in Space

Astroscale, a leading orbital operations company, has recently disclosed groundbreaking details about its pioneering approach to refueling satellites in space. Collaborating with the Space Force on a $25.5 million project, Astroscale aims to revolutionize the on-orbit servicing and repair industry, ensuring that valuable satellite investments do not go to waste.

One of the primary challenges faced by satellites in space is the depletion of fuel, leaving them unable to maintain their designated altitude and trajectory. Traditionally, this has resulted in satellites being allowed to deorbit, rendering them useless. However, Astroscale, along with other companies like OrbitFab, proposes a far more cost-effective solution.

Rather than investing another $100 million in launching a new satellite, Astroscale’s approach involves refueling existing satellites at a fraction of the cost. By pursuing a gas run from the Earth’s surface to geosynchronous orbit, companies can extend the operational lifespan of satellites that are still fully functional but lack the necessary fuel.

Astroscale’s breakthrough solution lies in its Astroscale Prototype Servicer for Refueling (APS-R). This compact satellite will ascend to around 300 kilometers above the Earth’s surface and rendezvous with a “prepared client” featuring a compatible refueling port. After successfully refueling the client satellite, the APS-R will conduct a thorough inspection to identify any fuel leaks or other potential issues.

Following the inspection, the APS-R will return to GEO+ and dock with a Defense Innovation Unit RAPIDS fuel depot—an orbital gas station. This fuel depot approach, chosen by Astroscale, prioritizes safety and efficiency, aligning with the military’s preference for geostationary pressure vessels containing hydrazine. Future iterations of this concept may include self-contained versions more suitable for non-military purposes.

While the project is still in its early stages, Astroscale anticipates delivering the APS-R by 2026. This joint endeavor, equally divided in terms of costs, emphasizes the importance of space sustainability and highlights the increasing significance of on-orbit servicing in the space industry. As the project progresses, further updates on this and other groundbreaking initiatives are expected to be unveiled.
