NASA plans to beam this video from the International Space Station back to Earth via laser.
It is set to be 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 used today.
Sent via the current the current ISS communication channel, TDRSS, it would take nearly 11 minutes to transmit this file. The OPALS laser will be able to downlink it in 3.5 seconds.
