Watch On <\/a><\/p>\n Europe’s Ariane 6 heavy-lift rocket is scheduled to launch today (Nov. 4) for the fourth time ever, and you can watch the action live.<\/p>\n An Ariane 6<\/a> is scheduled to lift off from Europe’s Spaceport<\/a> in Kourou, French Guiana today at 4:03 p.m. EST (2103 GMT; 6:03 p.m. local time in Kourou), carrying the Sentinel-1D Earth-observation satellite to low Earth orbit<\/a> (LEO).<\/p>\n You can watch the action live here at Space.com courtesy of Arianespace, or directly<\/a> via the France-based company, which operates the Ariane 6 for the European Space Agency<\/a> (ESA). Coverage will begin about 30 minutes before launch.<\/p>\n You may like<\/p>\n \n Europe’s Ariane 6 heavy-lift rocket launches on its second-ever mission, sending the CSO-3 satellite aloft from French Guiana on March 6, 2025. (Image credit: Arianespace)<\/p>\n The Ariane 6 is the successor to the Ariane 5<\/a>, which retired in July 2023<\/a> after 27 years of service. The new rocket debuted with a checkered July 2024 test flight<\/a>, then followed that up with two fully successful operational launches, in March<\/a> and August<\/a> of this year.<\/p>\n <\/p>\n Ariane 6 will go for three in a row today with the launch of Sentinel-1D, which is part of the European Union’s Copernicus Earth-observation program.<\/p>\n The Sentinel-1 series of satellites capture detailed radar imagery of Earth, “performing in all weathers, day and night,” ESA officials wrote in a Sentinel-1D mission description<\/a>. “This service is vital for disaster response teams, environmental agencies, maritime authorities, climate scientists \u2014 and other users who depend on frequent updates of critical data.”<\/p>\n Three Sentinel-1 satellites have launched to date, and two of those remain operational (Sentinel-1A and Sentinel-1C). Sentinel-1D will replace Sentinel-1A, which has been eyeing Earth from orbit for 11 years \u2014 well beyond its planned operational lifetime, according to ESA.<\/p>\n “The Sentinel-1D satellite will work in tandem with Sentinel-1C to generate timely data,” agency officials wrote in the description. “Both satellites have a C-band synthetic aperture radar (SAR) instrument on board, which captures high-resolution imagery of Earth’s surface. They are also equipped with Automatic Identification System (AIS) instruments to improve detection and tracking of ships.”<\/p>\n ‘Today’s launch will be Europe’s fifth orbital mission of 2025. In addition to the two previous Ariane 6 flights, Arianespace’s Vega C<\/a> smallsat launcher has aced two missions so far this year, in April and July.<\/p>\n For context, SpaceX<\/a> has launched 140 missions of its workhorse Falcon 9<\/a> rocket in 2025. More than 70% of those flights have been devoted to building out the company’s Starlink<\/a> megaconstellation in LEO.<\/p>\n","protected":false},"excerpt":{"rendered":"Vol VA265 | Sentinel-1D | Ariane 6 I Arianespace – YouTube Watch On Europe’s Ariane 6 heavy-lift rocket…\n","protected":false},"author":2,"featured_media":243307,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[90,416,56,54,55],"class_list":{"0":"post-243306","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-science","9":"tag-space","10":"tag-uk","11":"tag-united-kingdom","12":"tag-unitedkingdom"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/243306","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=243306"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/243306\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/243307"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=243306"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=243306"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=243306"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"a](\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2025\/11\/gY5MvFLBrL5PQcTUUM8Qy4.jpg\")
