US spacecraft's solar sail successfully deploys

A new spacecraft's solar sail successfully deployed Tuesday one month after launch, as it journeys around earth carrying a small satellite.
LightSail 2, as the spacecraft is called, will harness the momentum of packets of light energy known as photons.
Its developer, the Planetary Society, a US organization that promotes space exploration, marked the occasion on Twitter with: "DEPLOYMENT COMPLETE!"
"All indications are that LightSail2 has successfully deployed its solar sail!" it said, based on data sent back to Earth from the spacecraft. The organization added that forthcoming photographs would confirm the event later in the day.
