NASA Deployment of the Space Station's Roll Out Solar Array Experiment

Over the weekend of June 17-18, engineers on the ground remotely operated the International Space Station's Canadarm2 to extract the Roll Out Solar Array experiment from the SpaceX Dragon resupply ship. The experiment will remain attached to the Canadarm2 over seven days to test this advanced, flexible array that rolls out like a tape measure. via NASA http://www.nasa.gov/image-feature/deployment-of-the-space-stations-roll-out-solar-array-experiment
