A cosmic chase: Taters and the red dot
The mesmerizing 15-second video showcases the playful antics of an orange tabby cat named Taters as it enthusiastically chases the elusive red dot from a laser pointer across a couch. What makes this feat even more remarkable is that the video was transmitted through the Deep Space Optical Communications experiment (DSOC), a cutting-edge technology that may revolutionize data transmission in the realm of space exploration.
The memorable video: Taters the cat
A fun twist to technical triumph
Uploaded before launch, the short ultra-high definition video stars Taters, an orange tabby cat belonging to a JPL employee. The video captures Taters chasing a laser pointer, overlaid with graphics illustrating various features of the tech demo, including Psyche’s orbital path, Palomar’s telescope dome, and technical details about the laser and its data bit rate.
Internet speed marvel
Despite transmitting from millions of miles away, the video reached Earth faster than typical broadband internet connections. The connection between Palomar and JPL over the internet was slower than the signal from deep space—a testament to the efficiency of NASA’s groundbreaking technology.
Historical allure
The use of a cat in this video brings to mind the historical connection between groundbreaking technology demonstrations and popular culture. In 1928, a small statue of Felix the Cat was featured in television test broadcast transmissions, foreshadowing the internet era’s fascination with cat videos and memes.
Milestone after milestone
Continuous advancements
This recent milestone follows the achievement of “first light” on November 14, where the system demonstrated faster data downlink speeds and increased pointing accuracy during weekly checkouts. The project showcased downlink bit rates of 62.5 Mbps, 100 Mbps, and 267 Mbps on December 4, comparable to broadband internet download speeds. A total of 1.3 terabits of data was downloaded during this period, surpassing the data downlinked by NASA’s Magellan mission to Venus over its entire mission from 1990 to 1994.
Learning curve
Ken Andrews, project flight operations lead at JPL, acknowledges the cautious approach initially taken with this new technology. However, the team, with the support of Psyche colleagues, has adapted to the system’s intricacies, achieving longer lock-ons to spacecraft and ground terminals during checkouts. Each step in this experimental journey provides valuable insights into the capabilities of the Deep Space Optical Communications system.
More about the mission
