NASA probe transmitted video via laser beam from a distance of 31 million kilometers (2 photos + 1 video)
The video with the cat covered a huge distance in just 101 seconds.
NASA experts reported that for the first time in record time, they were able to transmit high-resolution video to Earth from deep space. The Psyche space probe, which is heading towards the asteroid of the same name, using the Deep Space Optical system, sent from a distance of 31 million km a 15-second video of a cat playing with a laser beam. The video was also sent to Earth using a laser beam, and the cat, by the way, belongs to one of the NASA engineers.
It is noted that the data transfer test took place on December 11. During the test session, the team managed to download 1.3 Tbits of data. As for the video with the cat, it was transmitted in 101 seconds. NASA said the maximum downlink speed was 267 Mbps and the minimum was 62.5 Mbps.

NASA noted that the Deep Space Optical system should transmit data 10-100 times faster than radio frequency space communications systems. However, the system will be tested more than once. But scientists do not plan to use it to transmit scientific data; they are only interested in testing the technology. The system will be turned on for the last time when the zone is close to Mars, approximately 330 million km from Earth.
The signal encoded in the laser beam was received by an installation mounted on the telescope of the Palomar Observatory of the California Institute of Technology
