NASA uses lasers to transfer a video from space to Earth

The Department was able to us National Aeronautics and Space Administration NASA to send a video from space to Earth using "laser" new contacts, which provide much higher transfer speeds compared to conventional radio-wave technology.

Therefore, the NASA sends a laser beam a 418 km fast 28, 163.5 km/h, international space station and the ground station telescope optical communication laboratory "in the city of raitood, in the US State of California.

The agency used to transfer the video clip entitled "Hello World!" Hello, World! Not exceeding 37 seconds, a new communications tool laser "optical science payload communications laser" OPALS.

It took the video transfer from space to the Earth station is only 3.5 seconds, which is much faster than the methods used by scientists.

And Matt, said Abrahamson, the Director of the OPALS "Jet Propulsion Laboratory of NASA and object in Pasadena, Calif." we collect a massive amount of data in space, we need to move them all to the ground. " "This (telecommunications laser) alternative much faster than traditional alrdioih waves that we use to communicate with the Earth."
Abrahamson also said they're looking to experiment new laser communications tool OPALS in the coming months in the hope that their findings will lead to better capabilities for Visual communication can be used in space exploration missions.

In a similar context, the team of researchers from the Massachusetts Institute of technology in collaboration with NASA and rely on laser communications, review of the system for the delivery of broadband broadband Broadband "speeds 19.44 Mbps to the Moon during the event to be held during the month of June.
