Video: Roll-Out Solar Array Experiment (ROSA) Deploys on ISS

Video Caption: The Roll-Out Solar Array (ROSA) was deployed from the end of the Canadarm2 robotic arm Sunday, June 18 outside the International Space Station. ROSA is an experiment to test a new type of solar array that rolls open in space like a party favor and is more compact than current rigid panel designs.

The ROSA investigation tests deployment and retraction,characterizes changes when the Earth blocks the sun, vibration and other physical challenges to determine the array’s strength and durability.

ROSA has the potential to replace solar arrays on future satellites, making them more compact and lighter weight. Satellite radio and television, weather forecasting, GPS and other services used on Earth would all benefit from high-performance solar arrays. The payload will remain deployed for seven days before retracting and will be stowed back inside the trunk of SpaceX’s Dragon cargo vehicle.

Note: footage of deploy is sped up 300%.

WASHINGTON (NASA PR) — NASA will host a media teleconference at 10 a.m. EDT Friday, May 26, to discuss select science investigations launching on the next SpaceX commercial resupply flight to the International Space Station.

SpaceX is targeting June 1 for the launch of its Dragon spacecraft on a Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
