Robotic Refueling Mission: The Main Event

The prospect of robots in space tantalizes NASA engineers with extraordinary possibility. Powerful and sophisticated, these tools may be able to extend the working lives of aging spacecraft, something that would profoundly change the way we manage expensive flight hardware. The Robotic Refueling Mission tests this proposition with a battery of demonstrations, culminating in the marquee event. This video takes a look at the progress made through proof-of-concept testing aboard the International Space Station in January 2013. Credit: NASA's Goddard Space Flight Center
