On April 23, NASA launched a solar sail protype to orbit around our planet — a piece of technology that could very well revolutionize the way we think about spacecraft propulsion. Then, on Aug. 29, the agency confirmed this sail successfully unfurled itself in outer space. Yet, we still didn't have official photographic evidence of this for some time.
Now, as of Sept. 5, we indeed do. NASA has released the first image of the open solar sail, formally called the Advanced Composite Solar Sail System, and stated that the spacecraft from which the sail was released will continue to send back more footage and data as time goes on.
