Madrid. (EP) -. NASA has sent the first video from the International Space Station to Earth via laser , this Thursday, June 5. This is the first official broadcast Optical Instrument Payload for Lasercomm Science (OPALS).
With a tribute to the first standard output of a computer program, and a nod to enthusiasm of the young team behind this new technology, the message and title of the video is. “Hello World”The message went through the space between the ISS and Earth in 3.5 minutes long faster compared to the 10 minutes required to send messages by radio, said the U.S. space agency said in a statement
This technology demonstration is an important step in changing the way NASA will contact spacecraft in the future. Data transmission for optical communication is much higher than for radio frequencies.
High Speed scientific instruments used in space missions increasingly require higher communication speeds to transmit the collected data to Earth or to support applications of high-speed data transmissions such as HD video. Optical laser ommunications (Lasercom) is an emerging technology that the data is sent through lasers. This offers the promise of much higher speeds than can be achieved with data radio frequency (RF) and has the advantage of operating in a frequency band that is currently unregulated. “Optical communications has great potential,” said mission manager Matt Abrahamson. “Right now, many of our missions in deep space are reported in 200 to 400 kilobits per second. OPALS show up to 50 megabits per second and future optical communication systems will provide deep space over gigabits per second from Mars.
