00:00A NASA solar sail that you can spot from the ground,
00:03there's a new opportunity to observe a bright NASA spacecraft sailing across the night sky.
00:10NASA's Advanced Composite Solar Sail System, or ACS-3, is a small satellite that's testing
00:15new technologies in low Earth orbit. It recently deployed its 30-foot-wide solar sails. These are
00:22a means of propulsion that could allow small spacecraft to sail on sunlight. The ACS-3 solar
00:28sails are highly reflective and make the spacecraft appear nearly as bright as Sirius, the brightest
00:34star in the sky. You can find out when the solar sail spacecraft will pass over your location
00:40using the NASA app on your mobile device. Stay up to date on NASA's missions exploring the
00:46solar system and beyond at science.nasa.gov. I'm Preston Dyches from NASA's Jet Propulsion Laboratory,
00:52and that's what's up for this month!
00:59Here we go.
