LightSail deploys, then falls silent again

For many reasons, mostly political but partly ethical, I do not use Google, Facebook, Twitter. They practice corrupt business policies, while targeting conservative websites for censoring, facts repeatedly confirmed by news stories and by my sense that Facebook has taken action to prevent my readers from recommending Behind the Black to their friends.
Thus, I must have your direct support to keep this webpage alive. Not only does the money pay the bills, it gives me the freedom to speak honestly about science and culture, instead of being forced to write it as others demand.

Though it appears that LightSail has successfully deployed its solar sail — the main objective of this engineering flight, the Planetary Society cubesat ceased communications shortly thereafter.

To confirm the success of the mission they need to re-establish communications, which they hope will happen when the spacecraft’s orbit exposes it to more sunlight and the battery gets charged.

    Successfully deployed the solar panels, not the sail. Sail apparently can’t deploy until solar panels adequately charge up the on-board battery.
