Besides aiding the GEO satellite community, a capability to fix and relocate "ailing" satellites also could help manage the growing orbital debris problem that threatens continued space operations, ultimately making space greener and more sustainable.
How RRM Is Making a Difference
Built by SSCO in the span of 18 months, the washing-machine-sized RRM module contains the components, activity boards and tools to practice several of the tasks that would be performed in orbit during a real servicing mission. Launched to the space station on July 8, 2011, aboard the final mission of the Space Shuttle Program, RRM was the last payload an astronaut ever removed from a shuttle.
In 2012, RRM demonstrated dexterous robotic operations in space. Dextre's 12-foot arm and accompanying RRM tool successfully snipped two twisted wires -- each the thickness of two sheets of paper -- with only a few millimeters of clearance: a task essential to the satellite refueling process.
The RRM refueling demonstration on Jan. 14-24 will employ the Canadian-built Dextre, NASA's RRM module and four unique RRM tools to show that space robots controlled from Earth -- hundreds or even thousands of miles below -- can transfer fuel to satellites with triple-sealed valves that were never designed to be accessed.
"The RRM operations team is very excited about the upcoming refueling demonstration," says Charlie Bacon, RRM operations manager. "Over the last two years, the team has put in more than 300 hours of preparation -- reviewing procedures, running simulations, and communicating with team members from other NASA centers and our international partners.
