In a significant advancement for deep space communication, NASA has successfully transmitted a high-definition video over a distance of 19 million miles. This achievement represents a critical step forward in enhancing data transmission capabilities for space exploration. The pioneering effort involved streaming a video featuring a cat named Taters.
The Deep Space Optical Communications experiment, conducted by NASA, successfully transmitted an ultra-high-definition video on December 11 from a remarkable distance of 19 million miles (approximately 31 million kilometers, or nearly 80 times farther than the distance between Earth and the Moon). This experiment is part of NASA’s initiative to demonstrate the potential for streaming high-bandwidth video and other forms of data from deep space, a crucial component for future human missions beyond Earth’s orbit.
NASA Deputy Administrator Pam Melroy highlighted this achievement as a testament to NASA’s dedication to advancing optical communications, a vital technology for meeting future data transmission needs in space exploration. The increase in bandwidth is essential for accomplishing NASA’s objectives in exploration and scientific research.
The historic video, featuring Taters the cat, was transmitted by the DSOC (Deep Space Optical Communications) transceiver aboard the Psyche spacecraft, located nearly 19 million miles from Earth. The event, celebrated by the DSOC team at NASA’s Jet Propulsion Laboratory, was a first in high-definition video streaming via laser from deep space.
The transmission utilized a state-of-the-art flight laser transceiver, which took 101 seconds to send the video signal to Earth at a maximum bit rate of 267 Mbps. The near-infrared laser signal was received by the Hale Telescope at the Palomar Observatory in San Diego County, California, and then relayed live to NASA’s Jet Propulsion Laboratory.
Launched as part of NASA’s Psyche mission on October 13, this laser communications demo is engineered to transmit data from deep space at speeds far surpassing current radio frequency systems. The technology will enable high-data-rate communication, vital for transmitting complex scientific data, high-definition images, and videos, as humanity prepares for missions like manned exploration of Mars.
Bill Klipstein, the project manager at JPL, explained that the objective was to demonstrate the capability of transmitting broadband video across millions of miles. To mark this significant occasion, a special video was created, featuring Taters the cat, to symbolize the essence of the Psyche mission’s tech demonstration.
The 15-second ultra-high-definition video, streamed via laser, showcases an orange tabby cat named Taters. It was not only a demonstration of advanced communication technology but also included graphics illustrating various aspects of the mission, such as Psyche’s orbit and technical details of the laser system.
The video, preloaded before launch, portrays Taters chasing a laser pointer. The overlayed graphics provide insights into various technical elements of the demonstration, including the data bit rate of the laser. Remarkably, the video transmission from deep space was faster than most broadband internet connections, a feat highlighted by Ryan Rogalin, the project’s receiver electronics lead at JPL.
Historically, cats have been a part of broadcasting milestones, dating back to 1928 with Felix the Cat used in television test broadcasts. Today, cat videos continue to be immensely popular online.
Following the achievement of “first light” on November 14, the system has demonstrated improved data downlink speeds and pointing accuracy. Ken Andrews, the project flight operations lead at JPL, emphasized the team’s increasing proficiency with the system, resulting in enhanced communication capabilities during each testing phase.
The Deep Space Optical Communications demonstration is part of NASA’s ongoing efforts to advance optical communication technology, supported by the Technology Demonstration Missions program and the Space Communications and Navigation program. The Psyche mission, managed by JPL and led by Arizona State University, is a part of NASA’s Discovery Program and is supported by various other NASA departments and external partners.
