The video, including a feline called Taters, was returned from almost 19 million miles away by NASA’s laser interactions presentation, marking a historical turning point.
NASA’s Deep Space Optical Communications experiment beamed an ultra-high meaning streaming video on Dec. 11 from a record-setting 19 million miles away (31 million kilometers, or about 80 times the Earth-Moon range). The turning point belongs to a NASA innovation presentation focused on streaming extremely high-bandwidth video and other information from deep area– allowing future human objectives beyond Earth orbit.
“This achievement highlights our dedication to advancing optical interactions as a crucial element to satisfying our future information transmission requires,” stated NASA Deputy Administrator Pam Melroy. “Increasing our bandwidth is necessary to accomplishing our future expedition and science objectives, and we eagerly anticipate the ongoing improvement of this innovation and the change of how we interact throughout future interplanetary objectives.”
The demonstration transferred the 15-second test video through an advanced instrument called a flight laser transceiverThe video signal took 101 seconds to reach Earth, sent out at the system’s optimum bit rate of 267 megabits per second (Mbps). Efficient in sending out and getting 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. Each frame from the looping video was then sent out “live” to NASA’s Jet Propulsion Laboratory in Southern California, where the video was played in genuine time.
