The footage wasn\u2019t of distant celestial bodies or spacecraft, but of a cat called Taters chasing a laser pointer.<\/p>\n<p>Abhijit Biswas at NASA\u2019s Jet Propulsion Laboratory (JPL) tells <em>New Scientist<\/em> that Taters was chosen for the first transmission over that distance because RCA\u2019s first television test broadcast also featured a cat, and that the inclusion of a laser pointer was a visual nod to the use of lasers in the transmission.<\/p>\n<p>\u201cApparently this cat is very fond of chasing laser pointers, so somehow that all came together in this video,\u201d says Biswas.<\/p>\n<p>The 15-second video was transmitted from NASA\u2019s Deep Space Optical Communications (DSOC) experiment, which is hitching a ride with the Psyche spacecraft that launched in October to intercept an asteroid of the same name.<\/p>\n<p>\n    <iframe loading=\"lazy\" title=\"NASA sends cat video 31,000,000 kilometres through space\" width=\"1110\" height=\"624\" src=\"https:\/\/www.youtube.com\/embed\/fp_3L7BtyRg?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><br \/>\n    <\/iframe>\n<\/p>\n<p>The video of Taters \u2013 a cat belonging to a JPL employee \u2013 was shot and uploaded to the craft before launch. The video also shows Psyche\u2019s orbital path, Palomar\u2019s telescope dome and technical information about the laser and its data bit rate.<\/p>\n<p><span class=\"js-content-prompt-opportunity\"\/><\/p>\n<p>The DSOC experiment will send high-bandwidth test data to Earth during a two-year run, and is part of NASA\u2019s long-term plan to use lasers rather than radios to transmit information. This will enable wider bandwidths and therefore faster data transfer rates that can carry complex scientific information, high-definition imagery and video for future missions.<\/p>\n<p>\u201cDSOC is really a proof of concept which hopefully will make believers out of everybody that this can be done,\u201d says Biswas. The technique has been used to send data between the moon and Earth, but that is a mere 384,400 kilometres. Biswas says longer distances should be possible in future.<\/p>\n<p>\u201cIt\u2019s a very narrow beam; at the distance that Psyche is right now, it covers only a few hundred kilometres,\u201d says Biswas. \u201cSo if you mispoint it ever so slightly you\u2019ll be in the Pacific Ocean or somewhere else. You\u2019ll completely miss. So that was something there was a lot of anxiety over.\u201d<\/p>\n<p>The video was transmitted at near infrared wavelength by a laser transceiver and took 101 seconds to travel the distance between the craft and Earth.<\/p>\n<p>The 267-megabits-per-second message was received by equipment at the Hale Telescope at Caltech\u2019s Palomar Observatory in San Diego County, California, before being transmitted over the internet to the JPL in Southern California, where the video was played in real time. That data rate makes DSOC faster than most domestic broadband connections.<\/p>\n<section class=\"ArticleTopics\">\n<p class=\"ArticleTopics__Heading\">Topics:<\/p>\n<\/section><\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/www.newscientist.com\/article\/2409483-nasa-sends-cat-video-31-million-kilometres-through-space\/?utm_campaign=RSS%7CNSNS&#038;utm_source=NSNS&#038;utm_medium=RSS&#038;utm_content=space&#038;rand=772163\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A video of Taters the cat chasing a laser light has been beamed back from space NASA NASA has broken its own record by transmitting ultra-high-definition video over a distance&hellip; <\/p>\n","protected":false},"author":1,"featured_media":775988,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[39],"tags":[],"class_list":["post-775987","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-new-scientist"],"_links":{"self":[{"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/posts\/775987","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=775987"}],"version-history":[{"count":0,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/posts\/775987\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/media\/775988"}],"wp:attachment":[{"href":"https:\/\/spaceweekly.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=775987"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=775987"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=775987"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
