Space Force Initiative to Revolutionize Satellite Refueling

The task of refueling satellites in space has always been a challenge. However, a recent development by a Space Force-funded initiative is set to change that. Astroscale has been awarded a $25.5 million contract to design and construct an orbital transfer vehicle known as the Astroscale Prototype Servicer for Refueling (APS-R). The goal is to have the vehicle ready for launch by 2026.

The APS-R will operate in geostationary Earth orbit (GEO), approximately 22,000 miles above Earth. This region is home to numerous military, government, and commercial satellites that provide vital communication, weather, and national security services. Without the ability to check, fix, or update these satellites, their functionality and lifespan are limited. The APS-R aims to change that by specializing in refueling compatible satellites, providing fuel directly to them to enhance their longevity and functionality.

If successful, the APS-R has the potential to revolutionize the in-space refueling process. It will carry and deliver fuel, specifically hydrazine, to other spacecraft, allowing them to continue their missions without interruption. The APS-R is designed to be about the size of a gas pump and will be capable of performing multiple refueling tasks in GEO.

While there are other initiatives and concepts for similar orbital transfer vehicles, none of them directly refuel satellites in space like the APS-R. This innovation sets the APS-R apart from ventures such as Northrop Grumman’s Mission Extension Vehicle (MEV) and DARPA’s Robotic Servicing of Geosynchronous Satellites (RSGS) program.

The APS-R project demonstrates the Space Force’s commitment to securing and strengthening the U.S. Space Force’s position in the evolving space domain. By enhancing responsiveness and overall mission capabilities, this initiative ensures the sustainability of space assets. The concept of an orbital gas station aligns perfectly with the mission of the Space Force – to maintain a functional, flexible, and secure space environment.

As we look to the future, the APS-R project offers a glimpse of the innovative advancements that will shape the space industry. With new possibilities for satellite refueling, the potential for longer missions, improved functionality, and reduced waste becomes a reality. The Astroscale Prototype Servicer for Refueling represents a significant leap forward and paves the way for exciting developments in space technology.
