From there the spacecraft, safely stored in its protective casing, will be transported to launch preparation facilities at the European Spaceport in Kourou.<\/p>\n<p>This is the start of a launch campaign that will lead up to the launch date, still to be announced. The satellite will reach its orbit on board an Ariane 6.<\/p>\n<p>Meanwhile, the Sentinel-1 mission will continue to deliver a supply of radar images of Earth\u2019s surface, performing in all weathers, day-and-night. It makes a key contribution to Europe\u2019s Copernicus programme by supporting a broad range of applications that help manage our environment, understand and tackle the effects of climate change and safeguard everyday lives.<\/p>\n<p>\t\t\t\t\t\t\t<a href=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2025\/04\/Sentinel-1_radar_image_compared_to_interferogram\" rel=\"nofollow noopener\" target=\"_blank\">Sentinel-1 interferogram of Myanmar earthquake<\/a><\/p>\n<p>The Sentinel-1 mission has contributed data to scientific studies on a wide range of topics, including these recent examples:<\/p>\n<p>Sentinel-1D will continue this work and will now undergo a series of launch preparation activities to ensure it is ready for liftoff.<\/p>\n<p>Ram\u00f3n Torres, Sentinel-1 Satellite Mission Director at ESA, commented, \u201cThis time we are launching the fourth Sentinel-1 satellite, and last of the first generation, on an Ariane 6, which will be an important moment for the whole of our space community. To see this mission, the first of the Copernicus programme family and a cornerstone of the Earth observation component of Europe\u2019s space programme, be lifted into orbit on Europe\u2019s newest heavy lift rocket, feels quite momentous. I would like to thank and congratulate all Sentinel-1 team members and our partners who have worked so diligently to make this milestone a huge success.\u201d<\/p>\n<p>\t\t\t\t\t\t\t<a href=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2025\/09\/Copernicus_Sentinel-1D_arrives_in_French_Guiana\" rel=\"nofollow noopener\" target=\"_blank\">Copernicus Sentinel-1D arrives in French Guiana<\/a><\/p>\n<p>Simonetta Cheli, Director of Earth Observation Programmes at ESA, added, \u201cIt is really a credit to the strong partnership between ESA and the European Commission that we are now preparing to launch another satellite for the Copernicus programme. Sentinel-1 has provided vital radar data that has been used in emergency responses, in scientific studies and in climate observation \u2013 a range of use-cases that highlights just how invaluable Copernicus is to our society.\u201d<\/p>\n<p>The Copernicus Sentinel-1 mission is based on a constellation of two identical satellites flying in the same orbit but 180\u00b0 apart, to optimise global coverage and data delivery for Copernicus.<\/p>\n<p>Sentinel-1A was the first satellite in the series, launched in April 2014, followed by the launch of Sentinel-1B in 2016. The Sentinel-1B mission came to an end in August 2022 after experiencing a technical fault that rendered it unable to acquire data. The satellite has been successfully\u00a0<a href=\"https:\/\/www.esa.int\/Applications\/Observing_the_Earth\/Copernicus\/Sentinel-1\/Sentinel-1B_journeys_back_to_Earth\" rel=\"nofollow noopener\" target=\"_blank\">de-orbited<\/a>\u00a0and will re-enter Earth\u2019s atmosphere within 25 years.

This powerful radar system operates in several modes, including wide swath and high-resolution, providing detailed data on land subsidence, ice movements and ocean conditions.<\/p>\n<p>And like the Sentinel-1C satellite that was launched last year, Sentinel-1D will also carry an Automatic Identification System (AIS), which is a new instrument designed to augment the SAR payload data for maritime ship traffic monitoring applications.<\/p>\n<p>Like<\/p>\n<p id=\"ezsr_just_rated_26863853\" class=\"ezsr-just-rated hide\">Thank you for liking<\/p>\n<p id=\"ezsr_has_rated_26863853\" class=\"ezsr-has-rated hide\">You have already liked this page, you can only like it once!<\/p>\n","protected":false},"excerpt":{"rendered":"Applications 11\/09\/2025 4652 views 35 likes The fourth satellite for the Copernicus Sentinel-1 mission, Sentinel-1D, has arrived at&hellip;\n","protected":false},"author":2,"featured_media":438600,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[64,63,128,285],"class_list":["post-438599","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-au","tag-australia","tag-science","tag-space"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/438599","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=438599"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/438599\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/438600"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=438599"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=438599"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=438599"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
