NASA has made a significant advancement in deep space communications by successfully transmitting high-definition video from 19 million miles away. This breakthrough paves the way for advanced data transmission in space exploration. The video was transmitted from a cat named Taters and marked a historic milestone for NASA’s laser communications demonstration.
The Deep Space Optical Communications Experiment on December 11 transmitted ultra-high-resolution streaming video from a record-setting distance of 19 million miles. This milestone is part of a NASA technology demonstration aimed at streaming extremely high-bandwidth video and other data from deep space to enable future crewed missions beyond Earth orbit.
NASA Deputy Administrator Pam Melroy stated, “This achievement confirms our commitment to advancing optical communications as a key element in meeting future data transmission needs. Increasing bandwidth is essential to achieving future exploration and science goals, and we look forward to continued advances in this technology and the transformation of how we communicate during future interplanetary missions.”
The 15-second test video was transmitted using a Flight Laser Transceiver at a maximum bit rate of 267 Mbps and took 101 seconds to reach Earth. The instrument transmitted a coded near-infrared laser to the Hale Telescope at the Palomar Observatory, where it was downloaded. Each frame of the video was transmitted “live” to NASA’s Jet Propulsion Laboratory in real time.
The video was sent via a Deep Space Optical Communications (DSOC) technology demonstration flight laser transceiver that was installed at NASA’s Jet Propulsion Center in April 2021 and later integrated with NASA’s Psyche spacecraft. The technology aims to transmit data from deep space 10 to 100 times faster than the most advanced radio frequency systems used in today’s deep space missions.
The ultra-high-definition video features a cat named Taters and was transmitted from deep space on December 11, 2023. The video was part of a technology demonstration known as Deep Space Optical Communications (DSOC) as the Psyche spacecraft heads towards the asteroid belt between Mars and Jupiter.
The system has demonstrated faster data downlink speeds and increased pointing accuracy during weekly checkouts. The project demonstrated downlink bit rates of 62.5 Mbps, 100 Mbps, and 267 Mbps, comparable to broadband Internet download speeds. The team was able to download a total of 1.3 terabits of data during that time, marking a significant technological achievement.
