NASA successfully conducted an experiment to send high-resolution video from deep space to Earth, and 'cat video' arrived at Earth from 31 million km away
NASA will conduct a test of ``Deep Space Optical Communications (DSOC),'' which transmits data from deep space to Earth, and will transmit a video of a staff cat playing from space to Earth. announced that it was a success.

NASA streams first video from deep space, featuring Taters the cat - The Washington Post

The spacecraft `` Psyche '' participating in the exploration mission to the asteroid ``Psyche'' was used for the data communication test conducted by NASA this time. On December 11, 2023, Saiki transmitted 15 seconds of high-resolution video from DSOC's flight laser transceiver, which can transmit and receive near-infrared signals, to the Hale Telescope at Caltech's Palomar Observatory.
The transfer speed of Saiki's laser communication device was a maximum of 267 Mbps, which is 10 to 100 times faster than the most advanced wireless communication systems used in conventional deep space missions, and it took only 101 seconds.
The actual footage used for the DSOC exam can be viewed below.
The main character of the historic video is Taters, a 3-year-old tabby cat owned by Joby Harris, who works at NASA's Jet Propulsion Laboratory (JPL). Taters is an American slang term for potatoes. When Mr. Harris adopted Taters, he thought it would be good to name them after ``potatoes,'' and a friend suggested Taters, so they decided on the name.
The movie shows Taters being obsessed with a laser pointer. Mr. Harris said it took him an hour to take a short video of the capricious Taters playing. Also, the text 'This is a test.' at the top of the screen is a point that Mr. Harris was particular about in order to imagine old NASA technology.
The video also includes technical information such as Psyche's orbit, Palomar Observatory's telescope dome, and the bit rate of the transmitting laser, as well as joke elements such as the Taters' breed, heart rate, and coat color. ____ is inside.
Test videos featuring cats have a history, and the popular cartoon character ``Felix the Cat'' was used in America's first television test broadcast in 1928. Even today, cat photos and videos are some of the most popular content online.
'We were able to transmit the video faster than most broadband Internet, even though it was transmitted from a far away location,' said Ryan Rogalin, head of receive electronics for the project at JPL. In fact, after receiving the video at Palomar Observatory, we sent it to JPL via the Internet, but the Internet connection was slower than the signal from deep space.JPL's Design Lab is able to introduce this technology. They've done a great job and Taters is already everyone's favorite.'

Psyche's favorite mission to transfer data this time is to explore the asteroid Psyche, the 14th mission of NASA's Discovery Program .
Psyche was launched on October 13, 2023, and will arrive in Psyche's orbit approximately six years later, in 2029. On the way to the asteroid belt between Mars and Jupiter, where Psyche is located, Psyche will spend at least two years conducting data transfer tests, the knowledge of which will be used for future Mars exploration missions.
