NASA and CSA Robotic Operations Advance Satellite Servicing
WASHINGTON — NASA’s Robotic Refueling Mission (RRM) examination aboard a International Space Station has demonstrated remotely tranquil robots and specialized collection can perform accurate satellite-servicing tasks in space. The plan outlines a miracle in a use of a space hire as a record exam bed.
“We and a partners are creation critical technological breakthroughs,” NASA Administrator Charles Bolden said. “As we pierce forward toward reaching a scrutiny goals, we will comprehend even some-more advantages from humans and robots operative together in space.”
The Canadian Space Agency’s (CSA) robotic handyman, Dextre, successfully finished a tasks Mar 7-9 on a space station’s outmost RRM module, designed to denote a tools, technologies and techniques indispensable to robotically refuel and correct satellites.
“The Hubble servicing missions taught us a significance and value of stealing innovative, cutting-edge technologies to circuit fast to broach good results,” pronounced Frank Cepollina, a maestro personality of 5 Hubble Space Telescope servicing missions and associate executive of a Satellite Servicing Capabilities Office (SSCO) during NASA’s Goddard Space Flight Center in Greenbelt, Md. “The impact of a space hire as a useful record exam bed can't be overstated. Fresh satellite-servicing technologies will be demonstrated in a genuine space sourroundings within months instead of years. This is huge. It represents genuine swell in space record advancement.”
Before a satellite leaves a ground, technicians fill a fuel tank by a valve that is sealed, lonesome and designed never to be accessed again. The RRM examination demonstrates a remote-controlled drudge can mislay these barriers and refuel such satellites in space.
Dextre successfully retrieved and legalised RRM tools, expelled reserve launch thatch on apparatus adapters, and used an RRM apparatus to cut intensely skinny satellite close wire. These operations paint a initial use of RRM collection in circuit and Dextre’s initial appearance in a investigate and growth project.
RRM was grown by SSCO and is a corner bid between NASA and CSA. During a subsequent dual years, RRM and Dextre will control several servicing tasks regulating RRM collection on satellite tools and interfaces inside and covering a cube-shaped RRM module.
NASA expects a RRM formula to revoke a risks compared with satellite servicing. It will inspire destiny robotic servicing missions by laying a substructure for them. Such destiny missions could embody a repair, refueling and repositioning of orbiting satellites.
“We are generally beholden to CSA for their partnership on this venture,” Cepollina said. “CSA has played a pivotal purpose in a growth of space robotics, from a early days of a space convey to a work they are doing with Dextre on space station.”
During a three-day RRM Gas Fittings Removal task, a 12-foot (3.7-meter) Dextre achieved a many perplexing charge ever attempted by a space robot: slicing dual apart “lock wires” 20 thousandths of an in. (0.5 millimeters) in hole regulating a RRM Wire Cutter Tool (WCT). Deftly maneuvered by ground-based goal operators and Dextre, a WCT uniformly slid a offshoot underneath a particular wires and severed them with usually a few millimeters of clearance. This wire-cutting activity is a exigency to stealing and servicing several satellite tools during any destiny in-orbit missions.
RRM operations are scheduled to resume in May 2012 with a execution of a gas equipment dismissal task. The RRM Refueling charge is scheduled for after this summer. NASA and CSA will benefaction RRM formula during a Second International Workshop on on-Orbit Servicing, hosted by Goddard May 30-31, 2012.
Dextre and RRM are an instance of how robots are changing operations in space. Another is Robonaut 2, or R2, a plan of NASA and General Motors. R2, a initial human-like robot, was launched into space in 2011 and is a permanent proprietor of a International Space Station.
