Using NASA’s first two-way, end-to-end laser relay system, pictures and videos of cherished pets flew through space over laser communications links at a rate

“The pet imagery campaign has been rewarding on multiple fronts for the ILLUMA-T, LCRD, and HDTN teams,” said Kevin Coggins, deputy associate administrator and SCaN program manager at NASA Headquarters in Washington. “Not only have they demonstrated how these technologies can play an essential role in enabling NASA’s future science and exploration missions, it also provided a fun opportunity for the teams to “picture” their pets assisting with this innovative demonstration.

Laser communications, also known as optical communications, employ infrared light instead of radio waves to send and receive information.
The HDTN implementation aggregates data from a variety of different sources, like discoveries from the scientific instrumentation on the space station, and prepares the data for transmission back to Earth. For the pet photo and video experiment, the content was routed using DTN protocols as they traveled from Earth to LCRD, to ILLUMA-T on the space station. Once they arrived, an onboard HDTN payload demonstrated its ability to receive and reassemble the data into files.
