NASA laser-based data transmission demonstrates serviceable internet 290 million miles from Earth | Scrolling Instagram should be a piece of cake for future Mars colonists
In late July, the Deep Space Optical Communications (DSOC) transmitted laser data across 290 million miles from the Psyche spacecraft back to Earth. That's roughly the maximum...
Project Operations Lead Meera Srinivasan at NASA's Jet Propulsion Laboratory said the milestone confirmed laser communications could be a "robust and transformative way" to explore the solar system at extreme distances. It then beams the information between a flight transponder on Psyche and two ground stations – one for uplink at JPL's Table Mountain facility and one for downlink at Caltech's giant 200-inch Hale Telescope in San Diego County. For example, when Psyche was 19 million miles from home in December, DSOC made history by sending the first ultra-high-def video footage from deep space starring a cat named Taters.
