LightSail 2 successfully demonstrates solar sailing

It shows that satellites can use the Sun to propel themselves.

LightSail 2 is faring much better than its ill-fated predecessor. The Planetary Society has verified that LightSail 2 successfully raised its orbit using solar sailing, making it the first small spacecraft to demonstrate the concept (though Japan's IKAROS was the first of any kind to fly). The team is now focused on raising the solar sailer's orbit for about a month's time as it continues to improve sail control through software updates and new techniques.

After the month has passed, the craft will spend another year gradually deorbiting.

It's a rare achievement in spaceflight, and notable when LightSail relied partly on crowdfunding to make their project a reality.

I'm unimpressed. But sadly so.
