Light Sail-satellite communicating again after problem with solar panels – update 2




Scientists can communicate again with the Light Sail-satellite after it for the second time gave no more signs of life. This time there were problems after unfolding the solar panels, which should ensure supply.

The Planetary Society, responsible for the launch, said on his website know that there was no communication with Light Sail. The problems started shortly after the satellite solar panels deploy in. Wednesday was the last sign of life, after which there is no communication signals are sent back. Saturday was the team, however, again a sign of life of Light Sail, making the testing process can be continued.

The communication problem was probably mainly due to the batteries. That fact did not flow from the solar panels after they were raised. Probably the process of unfolding problems caused by the batteries to seek to convert some sort of safe mode. The exact cause is not yet entirely clear: research is still being done to the battery troubles.

Because of the problems could solar sail, with a diameter of 32 meters, can not be extended. The sail to be used for propulsion. It namely captures photons on of the sun: that provide a minimal pressure on the sail, will cause the movement. This Light Sail working on the same kind of way as a sailboat. The Planetary Society will open the sail as soon as possible after the batteries are at a stable level. This may still happen Sunday.

Update 12:05 pm: Light Sail communicate again, and the article is adjusted accordingly.

Update 23:34 pm: Meanwhile Light Sail has unfolded its solar sail, so says The Planetary Society CEO Bill Nye on Twitter.
