NASA’s Psyche spacecraft achieved yet one more historic communications achievement lower than a month after efficiently firing its “first mild” laser information transmission. On December 11, the onboard Deep Area Optical Communications array’s flight laser transceiver despatched an “ultra-high definition” video clip roughly 19 million miles again to Earth—a brand new document not only for transmission, however for cat movies, as effectively.
Based on NASA’s December 18 announcement, Psyche despatched an encoded near-infrared laser beam to Earth final week at its most bandwidth pace of 267 megabits per second (Mbps) whereas en path to the area probe’s closing vacation spot, a metal-heavy asteroid positioned between Mars and Jupiter. Roughly 101 seconds later, researchers at Caltech’s Palomar Observatory obtained and downloaded the information package deal. The crew then despatched every particular person video body over to NASA’s Jet Propulsion Laboratory, the place the clip performed in actual time. After which, a cat named Taters made area exploration historical past.
As NASA explains, the 15-second video clip’s fundamental character is an ode to a few of the very first tv check broadcast transmissions. Starting in 1928, many of those earliest airings included a tiny statue of well-liked cartoon character, Felix the Cat. In honor of cats’ lengthy lineage in telecommunications, Psyche’s temporary scene showcases a large orange tabby named Taters chasing a pink laser pointer throughout a sofa whereas chilled out music performs within the background. Overlaid graphics additionally show details about the lovable cat similar to its coronary heart price, alongside extra pertinent venture information like Psyche’s orbital path, technical specs, and information bit price info.

Even throughout hundreds of thousands of miles of area, the demonstration reportedly holds as much as a few of the finest web obtain charges right here on Earth.
“Regardless of transmitting from hundreds of thousands of miles away, [Psyche] was in a position to ship the video quicker than most broadband web connections,” Ryan Rogalin, JPL’s receiver electronics lead for the venture, explained on Monday. “In actual fact, after receiving the video at Palomar, it was despatched to JPL over the web, and that connection was slower than the sign coming from deep area.”
Due to this and future Psyche laser system testing, NASA plans to prepared astronauts’ communications arrays for longterm voyages to the moon and Mars.
“Rising our bandwidth is important to reaching our future exploration and science targets, and we sit up for the continued development of this know-how and the transformation of how we talk throughout future interplanetary missions,” NASA Deputy Administrator Pam Melroy stated within the company’s December 18 announcement.
For now, nonetheless, Taters takes middle stage—though the video’s focus wasn’t solely a callback tv’s very first check broadcasts.
“Right this moment, cat movies and memes are a few of the hottest content material on-line,” reads NASA’s announcement, including in its accompanying material that, “Coincidentally, cats wish to chase lasers.”
