NASA transformed the International Space Station into a command center for a robot on Earth this month for a first-of-its-kind test drive of the technology and skills needed to remotely operate robots on the moon, Mars or an asteroid.
During the June 17 space technology test, NASA astronaut Chris Cassidy, a space station flight engineer, remotely controlled a K10 rover at the agency's Ames Research Center in Moffett Field, Calif. The robot was commanded to simulate deploying a polyimide-film antenna in a specially built "Roverscape" at the NASA center.

"We successfully conducted the first 'surface telerobotics' test session with the International Space Station," said Terry Fong, director of the Intelligent Robotics Group at Ames. "Cassidy used K10 to perform a surface site survey and to begin deploying a simulated Kapton film-based radio antenna."
When astronauts and robots team up
Fong said follow-up test sessions between rover and the space station will be conducted in late July and early August. Those sessions will focus on completing antenna deployment, inspecting the deployment and studying human-robot interaction.
"We're still finalizing the date of the next test session but anticipate that it will be sometime during the week of July 22," Fong told SPACE.com.
The technology demonstrations will also investigate how communication delays over large distances could influence an astronaut's aptitude to take supervisory control of a robot in the event the machinery finds itself in trouble or unable to move.
Fong was bullish on the rover/space station linkup. The test session, he said, was notable for achieving a number of firsts, including the following:
Proving ground for future missions
The test is the first high-fidelity simulation of a human-robot "waypoint" mission — an Earth-moon L2 lunar far side telescope deployment concept proposed by experts at the University of Colorado, Boulder and Lockheed Martin, builder of the NASA Orion spacecraft.
"It was a great success … and the team was thrilled with how smoothly everything went," said Jack Burns, director of the NASA Lunar Science Institute's Lunar University Network for Astrophysics Research, a NASA-funded center at the University of Colorado, Boulder.
The K10 rover deployed two 'arms' of Kapton film under the command of astronaut Cassidy, Burns said.
Burns is a leading advocate of a proposed piloted mission to the Earth-moon L2 position, from which astronauts within an Orion spacecraft would remotely unfurl a low-radio-frequency antenna on the moon's farside.
In the future, we plan such a deployment on the far side of the moon, where the Kapton film will be the backbone for a low-frequency radio telescope,” Burns told SPACE.com.
Once deployed on the lunar landscape, Burns said, an array of unfurled polyimide film could track down the "cosmic dawn" of the universe that occurred shortly after the Big Bang. The moon's farside is a radio-quiet locale in the inner solar system, allowing for sensitive observations of the first stars and galaxies that formed only 100 million years after the Big Bang, he said.
