NASA engineers work on the Restore-L payload in the high bay inside the Space Station Processing Facility (SSPF) at NASA's Kennedy Space Center in Florida, on May 16, 2019. Restore-L, managed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland, is an in-flight robotic satellite servicer spacecraft. The center is celebrating the SSPF’s 25th anniversary. The SSPF was built to process elements for the International Space Station. Now it is providing support for current and future NASA and commercial provider programs, including Commercial Resupply Services, Artemis 1, sending the first woman and next man to the Moon, and deep space destinations including Mars.

The Restore-L hose management assembly (HMA) test unit undergoes electromagnetic interference testing in the Electromagnetic Lab at NASA's Kennedy Space Center in Florida on Feb. 19, 2020. The HMA is able to extend and retract the hose, somewhat similar to the function of a tape measure.

Sen. Barbara Mikulski participated in a ribbon cutting at NASA’s Goddard Space Flight Center on January 6th, 2016, to officially open the new Robotic Operations Center (ROC) developed by the Satellite Servicing Capabilities Office (SSCO). Within the ROC's black walls, NASA is testing technologies and operational procedures for science and exploration missions, including the Restore-L satellite servicing mission and also the Asteroid Redirect Mission. Here, she receives an overview of a robotic console station used to practice satellite servicing activities. During her tour of the ROC, Sen. Mikulski saw first-hand an early version of the NASA Servicing Arm, a 2-meter-class robot with the dexterity to grasp and refuel a satellite on orbit. She also heard a description of Raven, a payload launching to the International Space Station that will demonstrate real-time, relative space navigation technology. The robotic technologies that NASA is developing within the ROC also support the Journey to Mars.

RROxiTT lead roboticist Alex Janas stands with the Oxidizer Nozzle Tool as he examines the work site. Credit: NASA/Goddard/Chris Gunn NASA has successfully concluded a remotely controlled test of new technologies that would empower future space robots to transfer hazardous oxidizer – a type of propellant – into the tanks of satellites in space today. Concurrently on the ground, NASA is incorporating results from this test and the Robotic Refueling Mission on the International Space Station to prepare for an upcoming ground-based test of a full-sized robotic servicer system that will perform tasks on a mock satellite client. Collectively, these efforts are part of an ongoing and aggressive technology development campaign to equip robots and humans with the tools and capabilities needed for spacecraft maintenance and repair, the assembly of large space telescopes, and extended human exploration.
