NASA Tests New Technologies for Refueling

Multiple NASA centers are currently conducting a remotely controlled test of new technologies that would empower future space robots to transfer satellite oxidizer into the propellant tanks of spacecraft in space today.

Building on the success of the International Space Station's landmark Robotic Refueling Mission (RRM) demonstration, the ground-based Remote Robotic Oxidizer Transfer Test (RROxiTT) is taking another step forward in NASA's ongoing campaign to develop satellite-servicing capabilities for space architectures and human exploration. 

On Earth, RROxiTT technologies could one day be applied to robotically replenish satellites before they launch, keeping humans at a safe distance during an extremely hazardous operation.
