US-based space agency NASA has managed to beam a HD video from the International Space Station to Earth using a new laser communications device. The ‘Hello World’ video was the first ever to “travel” via this technology.

The technology used was the Optical Payload for Lasercomm Science (OPALS). It took OPALS 3.5 seconds to transmit the “Hello World!” video – the process would have taken more than 10 minutes to complete using the more traditional downlink process.


“It's incredible to see this magnificent beam of light arriving from our tiny payload on the space station,” said Matt Abrahamson, OPALS mission manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, reported a statement published on the NASA website.

The 175-megabit video transmission happened for the first time on Thursday and has been likened to the upgrade from dial-up to DSL.

Because of the speed at which the space station moves through the sky - 17,500 mph - the precision of the laser needs to be immaculate.

NASA likens the task to “aiming a laser pointer at the end of a human hair 30 feet away and keeping it there while walking.”

The method could change the future of communication in deep-space missions.

“The International Space Station is a test bed for a host of technologies that are helping us increase our knowledge of how we operate in space and enable us to explore even farther into the solar system,” Sam Scimemi, International Space Station division director at NASA Headquarters in Washington stated.

“Using the space station to investigate ways we can improve communication rates with spacecraft beyond low-Earth orbit is another example of how the orbital complex serves as a stepping stone to human deep space exploration,” he added.

Couldn't they have transmitted something a bit more interesting than this US eulogy advertisement from WW2?

I could show you an email where I had that idea of sending signals on a laser beam, a year or so ago. Does that make me prescient, a genius, or is the NSA just reading my emails? Well, they took many of my ideas and never gave me credit or remuneration, the Pentagon that is, and who would believe it? Well, I'm sure I'm not the only one whose ideas were taken for free.

  


Beamshot or it didn't happen.

Ok, well communication via laser been around for a very long time even before your emails last year or even before emails were thought of in snail mail.
