NASA beamed this video from the International Space Station back to Earth via laser on June 5, 2014.
It is the first official transmission from the Optical Payload for Lasercomm Science, or OPALS. An homage to the standard first output of a computer program, and a nod to the young team's enthusiasm, the message and title of the video is, "Hello, World."
This technology demonstration is an important step in changing the way NASA communicates with future spacecraft. The data rates for optical communication are much higher than radio frequencies.
