4K video on Orion (Artemis II) using O2O <\/p>\n
For the Orion (Artemis II) Moon mission, 4K video is captured onboard by high\u2011resolution cameras (commercial off\u2011the\u2011shelf digital\u2011still\/video cameras adapted for space), then beamed back to Earth using O2O.<\/p>\n
4K video comes in two common formats: 3840\u00d72160 pixels (4K UHD) TV\/streaming, and 4096\u00d72160 pixels (DCI 4K) for digital cinema \u2014 the higher pixel count makes the picture much sharper and more detailed, especially on large screens.<\/p>\n
Instead of using traditional radio\u2011frequency links, it encodes the video data into infrared laser beams and shoots them toward ground\u2011based optical receivers in places like Las Cruces, New Mexico, and Table Mountain, California, which are chosen for low cloud cover. <\/p>\n
Data rate: O2O can transmit up to about 260 megabits per second, enough to send 4K high\u2011definition video from lunar distance in near\u2011real time.<\/p>\n
Why lasers help: Laser\u2011link wavelengths are much shorter than radio waves, so they can pack far more data into the same \u201cbeam width,\u201d allowing high\u2011resolution video without the multi\u2011day\u2011delay archives of older (Apollo) missions. <\/p>\n","protected":false},"excerpt":{"rendered":"4K video on Orion (Artemis II) using O2O For the Orion (Artemis II) Moon mission, 4K video is…\n","protected":false},"author":2,"featured_media":387486,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[61,60,172154,82,247],"class_list":{"0":"post-387485","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-ie","9":"tag-ireland","10":"tag-nasa-artemis-moon-flyby-astronauts","11":"tag-science","12":"tag-space"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/387485","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/comments?post=387485"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/387485\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/387486"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=387485"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=387485"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=387485"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
