NASA is a step closer to making robotic refueling of in satellites in space after a successful nine-day test on Earth.
In the test, operators in Maryland controlled an industrial robot more than 800 miles (1,287 kilometers) away in Florida, successfully transfering propellant into a mock tank. The February trial, known as the Remote Robotic Oxidizer Transfer Test (RROxiTT), tested a suite of new technologies and procedures that could potentially allow satellites to keep operating long after their original warranties expire.
