NASA’s Deep Space Optical Communications experiment beamed an ultra-high definition streaming video of a cat from a record-setting 31 million kilometres, or about 80 times the Earth-Moon distance.
The milestone, part of NASA technology demonstration aimed at streaming very high-bandwidth video and other data from deep space — enabling future human missions beyond Earth orbit — was achieved on December 11.
The the short ultra-high definition video, which was uploaded before launch on NASA’s Psyche mission on October 13, features an orange tabby cat named Taters, the pet of a JPL employee, chasing a laser pointer, with overlayed graphics.
The graphics illustrate several features from the tech demo, such as Psyche’s orbital path, Palomar’s telescope dome, and technical information about the laser and its data bit rate.
Tater’s heart rate, colour, and breed are also on display.
“This accomplishment underscores our commitment to advancing optical communications as a key element to meeting our future data transmission needs,” said NASA Deputy Administrator Pam Melroy.
“Increasing our bandwidth is essential to achieving our future exploration and science goals, and we look forward to the continued advancement of this technology and the transformation of how we communicate during future interplanetary missions,” Melroy added.
The demo transmitted the 15-second test video via a cutting-edge instrument called a flight laser transceiver.
The video signal took 101 seconds to reach Earth, sent at the system’s maximum bit rate of 267 megabits per second (Mbps).
Capable of sending and receiving near-infrared signals, the instrument beamed an encoded near-infrared laser to the Hale Telescope at Caltech’s Palomar Observatory in San Diego County, California, where it was downloaded.
