REPUBLIKA.CO.ID, JAKARTA – In a successful demonstration of new laser communications capabilities, NASA this month beamed ultra-high-definition (UHD) video over 19 million miles, or about 30.5 million kilometers, from the Psyche spacecraft to the early Earth Space.
Reported Engadget, Tuesday (December 26th, 2023), this is the first video Streaming UHD is sent from space via laser. The video is a 15-second clip in which an orange cat named Taters chases a laser dot.
The signal from the video sent on December 11 reached Earth within 101 seconds of Psyche’s current location. That’s about 80 times the distance between the Earth and the Moon.
The video was uploaded before the mission began and sent home Transceivers Laser flight on board the Psyche with 267 Mbit/s. The spacecraft, which began its journey in October, is on its way to study metal-rich asteroids in the main asteroid belt between the planets Mars and Jupiter.
“Despite transmitting from millions of miles away, it is capable of transmitting video faster than most Internet connections broadband”, said Ryan Rogalin, receiver electronics lead for the project at NASA’s Jet Propulsion Lab. In fact, after being received at Palomar, the video was sent to JPL over the Internet, and the connection was slower than signals from space.
