NASA has awarded a $142 million contract to Maxar Technologies of Westminster, Colorado, to robotically assemble a communications antenna and manufacture a spacecraft beam in orbit. The technology demonstration is slated to take place on NASA’s Restore-L spacecraft, designed to service and refuel a satellite in low-Earth orbit.

The Restore-L spacecraft will be modified to accommodate a payload called Space Infrastructure Dexterous Robot (SPIDER). The payload includes a lightweight 16-foot (5-meter) robotic arm. Previously known as Dragonfly during the ground demonstration phase of the NASA Tipping Point partnership, SPIDER will assemble seven elements to form a functional 9-foot (3-meter) communications antenna. The robotically assembled antenna will demonstrate Ka-band transmission with a ground station.

The payload also will manufacture a 32-foot (10-meter) lightweight composite beam using technology developed by Tethers Unlimited of Bothell, Washington. The manufacturing element of the demonstration will verify the capability to construct large spacecraft structures in orbit.

“We are continuing America’s global leadership in space technology by proving we can assemble spacecraft with larger and more powerful components, after launch,” said Jim Reuter, associate administrator of NASA’s Space Technology Mission Directorate. “This technology demonstration will open up a new world of in-space robotic capabilities.”

The second phase of the public-private partnership combines NASA resources with an industry contribution to reduce the overall cost to American taxpayers and the agency. The demonstration will mature technologies with cross-cutting applications for government and commercial missions, including human exploration of the Moon and Mars and in-space construction of large telescopes.

“In-space assembly and manufacturing will allow for greater mission flexibility, adaptability, and resilience, which will be key to NASA’s Moon to Mars exploration approach,” said Brent Robertson, project manager of Restore-L at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The Restore-L project is developing a suite of technologies capable of refueling and servicing satellites in space. The spacecraft is currently targeted for launch in the mid-2020s.

The SPIDER payload team includes Maxar, Tethers Unlimited, West Virginia Robotic Technology Center in Morgantown, and NASA’s Langley Research Center in Hampton, Virginia.

Restore-L and SPIDER are administered by the Technology Demonstration Missionsprogram based at NASA’s Marshall Space Flight Center in Huntsville, Alabama, on behalf of the agency’s Space Technology Mission Directorate. The SPIDER payload is managed by the Restore-L project within the Exploration and In-Space Services (ExIS) projects division (formerly known as the Satellite Servicing Projects Division), located at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
