So far, it's been smooth sailing for the LightSail 2. The solar spacecraft is orbiting on its own after being delivered to space last week aboard Space X's Falcon Heavy. The mission team of the Planetary Society confirmed on Wednesday that it has established two-way communications with LightSail 2 and is running various tests. According to the spacecraft's telemetry, all of its major systems appear to be operating normally. Over the next few days, a time will be set for LightSail 2 to deploy its signature solar sails which will propel it forward. Unlike traditional spacecraft which rely on rocket engines, LightSail 2's design is powered by photons from the sun. If successful, it will be the first controlled light sail ever to enter and maintain Earth orbit.
