NASA's robotic refueling demo set to jumpstart expanded capabilities in space
Date:1/10/2013

When we finally execute the namesake task of RRM, we anticipate that our work will culminate in proving that in-orbit satellite refueling is no longer future technology -- it's current technology."

Although the RRM module will never fix or refuel a satellite itself, its advanced tools and practice runs are laying the foundation for future in-orbit robotic servicing missions. Additional RRM demonstrations will continue into 2013, with a new round of servicing task boards, tools and activities slated to continue its investigations through 2015.

What's Next in Robotic Satellite Servicing?

The satellite-servicing concept that RRM is advancing is one that NASA has been developing for years. Beginning with the Solar Maximum repair mission in 1984, the servicing philosophy paved the way for five successful astronaut-based missions to upgrade and repair the Hubble Space Telescope and has been practiced more recently in spacewalks to assemble and maintain the space station.

With the RRM on the space station and a robust technology development campaign being conducted on the ground, NASA is testing capabilities for a new robotic servicing frontier. Since 2009, the Satellite Servicing Capabilities Office at NASA's Goddard Space Flight Center in Greenbelt, Md., has been aggressively advancing the robotic technologies for a free-flying servicer spacecraft that could access, repair and refuel satellites in GEO.

To this end, the SSCO team has been studying a conceptual servicing mission and building technologies to address uncharted territory such as autonomous rendezvous and docking, propellant transfer systems for zero gravity and specialized algorithms (computer commands) to orchestrate and synchronize satellite-servicing operations. A systems engineering review on this conceptual mission was recently conducted with positive responses from peer experts and external participants.
