LightSail successfully deploys solar sail

Engineers have confirmed that the cubesat prototype LightSail has successfully deployed its solar sails.

This is I think only the second time a solar sail has successfully deployed in space. More significant to me is the fact that it is the first time this kind of complex engineering test has been tried using a cubesat. If cubesats can begin to handle these kinds of tasks, unmanned satellite technology is going to take a gigantic leap forward.

LightSail back in business?

The Planetary Society’s solar sail engineering test called LightSail has re-established communications with the ground, allowing for the possibility that it can finally achieve its solar sail deployment, the main purpose of the mission.

I had previously reported that the sails had deployed, but a commenter correctly noted that only the panels have deployed, not the sails themselves, which need full battery power. The communications problem has been related to a battery charging problem. They are hoping that the batteries will get charged by mid-day today when they will try to deploy the sails.

Amateur astronomers can help a commercial space start-up by taking pictures of its cubesat SkyCube.

The cubesate was launched from ISS last week, but has not operated as expected and they want to know why. Images would help.
