Testing Continues for Satellite Servicing Capabilities

12.02.2013 — Engineers at NASA's Kennedy Space Center in Florida are partnering with counterparts at the agency's Goddard Space Flight Center in Maryland to develop systems to bring potential future robotic “service tow trucks” to orbiting spacecraft in need of aid. Operating under Goddard's Satellite Servicing Projects Division's (SSPD) technology development effort, the project is now moving into the next phase with a team at Kennedy developing a reliable and accurate prototype high-pressure propellant transfer assembly using lessons learned from recent testing.

11.20.2013 — To commemorate ISS's incredible achievements as a test bed for technology research and development, we present this 2011 image of the spacewalk that transferred NASA's Robotic Refueling Mission (RRM) module to ISS during STS-135, the final flight of the Shuttle Program. Since its arrival, RRM has been demonstrating the robotic tools, technologies and techniques needed to refuel and repair satellites in orbit — particularly "legacy" satellites, spacecraft that weren't designed to be serviced. #ISS15

07.18.2013 — The award was presented on July 17, 2013, at the second annual ISS Research and Development Conference in Denver, Colorado. SSPD's Jill McGuire, project manager of RRM, accepted on behalf of the team. “Receiving this award is a great honor as we are among so many deserving and valuable technology and scientific payloads on ISS,” said Mcguire. “We are proud to demonstrate the endless possibilities of satellite servicing technologies through the use of innovative robotic tools and techniques. We look forward to continued collaboration with our partners at the Canadian Space Agency in showing the world the maturity and breadth of robotic technology, as well as providing a sneak peek into the future on-orbit satellite refueling, repair and repositioning.

Team Completes Zero-Gravity Testing on Flexible Fuel Hose

06.18.2013 — After four days of tests on a zero-gravity airplane, the NASA satellite servicing team alighted with a wealth of data on the design of an innovative flexible fuel hose for robotic satellite refueling. Tests conducted June 4-6, 2013 placed the three-member team and the unique device through 120 twenty-second sessions of weightlessness, giving the team multiple opportunities to observe and measure the static and dynamic behavior of the hose in a microgravity environment.

06.04.2013 — Two assistants help during the flexible host conducted June 4-6, 2013 on a zero-gravity airplane. Data collected during the series of 20-second tests in microgravity will help the Satellite Servicing Projects Division in designing a host that is maneuverable yet strong enough to transfer corrosive satellite fuel on orbit.

05.24.2013 — On June 3, 2013, three satellite servicing team members will board a zero-gravity airplane to test the design of innovative flexible hose for satellite refueling. Here engineers Matt Sammons (SSCO, Goddard Space Flight Center) and Syrus Jeanes (Kennedy Space Center) hold up a fixture that will hold the hose. A mechanism at one end will "push" the flexible hose once the team has entered into microgravity. A series of cameras and sensors will then document how the hose acts.
