As part of the demonstration new possibilities of laser communication NASA transferred to Earth from its Psyche probe earlier this month ultra high definition videoand at an incredible distance over 19 million kilometers. This is the first time that UHD streaming video has been sent from deep space using a laser. That’s why this video will probably go down in history. What’s on it? It’s about ptwelve-second clipin which Taters cat indulges in a favorite cat pastime, viz chasing a laser point.
The signal from the video, which was sent on December 11, has reached Earth for 101 seconds from where Psyche was at the time, which is approx 80 times the distance between the Earth and the Moon. The clip was recorded before the launch of the mission and sent to Earth by the flight laser transmitter on board Psyche at a speed of 267 Mb/s. The probe, which set off on its journey in October, continues toward its goal of studying a metal-rich asteroid in the main asteroid belt between Mars and Jupiter.
“Even though it was broadcasting from millions of kilometers away, it was able to send video faster than most broadband internet connections,” said Ryan Rogalin, the project’s receiver electronics lead at NASA’s Jet Propulsion Laboratory. “Actually, after being received at Palomar, the video was sent to JPL over the Internet, and that connection was slower than the signal coming from deep space.”
