Separation of the upper stage occurred about nine minutes after liftoff, followed by the first firing of the upper stage. The upper stage \u2013 carrying four 715-kg Galileo satellites \u2013 flew in ballistic configuration for three hours and eight minutes, after which a second upper stage firing placed it into circular separation orbit. Once stabilised at 3h 35 min after liftoff, the Galileo dispenser released the first two satellites, followed by the second pair 20 minutes later.<\/p>\n<p>At orbital injection the launcher attained an altitude of 22 925 km, approximately 300 km below the Galileo satellites\u2019 operational altitude. The four satellites manoeuvred themselves up to this height, leaving the passivated upper stage safely in a \u2018graveyard orbit\u2019.<\/p>\n<p>Video credit: ESA<\/p>\n<p class=\"MsoNormal\" style=\"margin: 5px;\">&nbsp;<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Europe\u2019s Galileo satellite navigation system performed a giant leap nearer completion on Tuesday 12 December, as four more Galileo satellites have been launched into orbit by Ariane 5.<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[652,61,1,463],"tags":[67,144,268],"class_list":["post-2718","post","type-post","status-publish","format-standard","hentry","category-earth-science","category-launchers","category-space-exploration","category-videos","tag-ariane","tag-ariane-5","tag-galileo"],"_links":{"self":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts\/2718","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=2718"}],"version-history":[{"count":1,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts\/2718\/revisions"}],"predecessor-version":[{"id":2719,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts\/2718\/revisions\/2719"}],"wp:attachment":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=2718"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=2718"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=2718"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
