A spacecraft about the size of a gas pump is being developed for the US Space Force program to refuel orbiting satellites. The goal is to extend the lifespan of craft that have run out of juice instead of simply decommissioning them.

According to tracking service Orbiting Now, there are currently 9,707 satellites orbiting the planet right now. When some of those satellites run out of fuel, their usefulness is over and they become space junk rather than space-based tools – even if they’re in otherwise good health. To help solve this issue, in January the United States Space Force (USSF) awarded US$25.5 million to orbit-service provider Astroscale U.S. to create a refueling solution, as part of a larger program focused on keeping government satellites operational after their tanks are empty.

“The advent of in-air refueling completely changed the equation for the duration and distance of aircraft missions,” said Astroscale’s, Ron Lopez at the time. “The space industry is on the cusp of a similar fuel-led technological revolution, and I am thrilled that SSC has selected Astroscale U.S. to develop APS-R to bring fuel to its client spacecraft.

“This innovation in on-orbit servicing will ultimately extend the range and mobility of satellites in orbit, allowing the USSF to do more with their operational assets. APS-R opens the door to rethinking the way satellites are designed and operated, marking a significant leap forward in the capabilities and sustainability of satellites in orbit.”
