They practiced powering up the spacecraft, simulated fueling operations for the SpaceX Falcon Heavy rocket, conducted mock weather briefings, and practiced troubleshooting a variety of scenarios.<\/p>\n<p class=\"wp-block-paragraph\">This rehearsal is a standard part of preparation and contributes to mission success, especially since NASA missions often involve unique requirements specific to a given spacecraft. During the simulation, the team was on console at NASA and SpaceX facilities at Cape Canaveral Space Force Station and at SpaceX facilities at the agency\u2019s Kennedy Space Center, where they tested and demonstrated proficiency on everything from communications to mission systems.<\/p>\n<p class=\"wp-block-paragraph\">Completing the rehearsal brings the team one step closer to sending Roman on its mission to address essential questions about dark energy, planets outside our solar system, and infrared astrophysics. By conducting wide-field surveys, the telescope will explore the universe\u2019s structure, evolution, and composition.<\/p>\n<p class=\"wp-block-paragraph\">NASA and SpaceX are targeting launch no earlier than 7:26 a.m. EDT on Sunday, Aug. 30, from Launch Complex 39A at Kennedy aboard a SpaceX Falcon Heavy.<\/p>\n<p class=\"wp-block-paragraph\">Follow the Roman mission at:<\/p>\n<p class=\"wp-block-paragraph\">X: <a href=\"https:\/\/x.com\/NASARoman\" rel=\"nofollow\">@NASARoman<\/a>, <a href=\"https:\/\/x.com\/NASAUniverse\" rel=\"nofollow\">@NASAUniverse<\/a>, <a href=\"https:\/\/x.com\/NASAKennedy\" rel=\"nofollow\">@NASAKennedy<\/a><br \/>FB: <a href=\"https:\/\/www.facebook.com\/NASARoman\" rel=\"noopener nofollow\" target=\"_blank\">@NASARoman<\/a>, <a href=\"https:\/\/www.facebook.com\/NASAGoddard\" rel=\"noopener nofollow\" target=\"_blank\">@NASAGoddard<\/a>, <a href=\"https:\/\/www.facebook.com\/NASAKennedy\/\" rel=\"noopener nofollow\" target=\"_blank\">@NASAKennedy<\/a><br \/>Instagram: <a href=\"https:\/\/www.instagram.com\/nasagoddard\/\" rel=\"noopener nofollow\" target=\"_blank\">@NASAGoddard<\/a>, <a href=\"https:\/\/www.instagram.com\/nasauniverse\/\" rel=\"noopener nofollow\" target=\"_blank\">@NASAUniverse<\/a>, <a href=\"https:\/\/www.instagram.com\/nasakennedy\/\" rel=\"noopener nofollow\" target=\"_blank\">@NASAKennedy<\/a><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2026\/08\/17c9ae8c3df1bfbae89a3f09f23caa1a4e9e7ccee32a478d2371dad23800d628.png\"\/><\/p>\n<p>August 20, 2026 5:22PM<\/p>\n<p>More from Nancy Grace Roman Space Telescope<script async src=\"\/\/www.instagram.com\/embed.js\"><\/script><\/p>\n","protected":false},"excerpt":{"rendered":"The team preparing to launch NASA\u2019s Nancy Grace Roman Space Telescope completed a mission dress rehearsal on Thursday&hellip;\n","protected":false},"author":2,"featured_media":599603,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[909,1748,130612,9411,1507,61,60,14738,10110,181736,108006,21991,82,247],"class_list":["post-599602","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-astrophysics","tag-dark-energy","tag-dark-matter-dark-energy","tag-exoplanets","tag-goddard-space-flight-center","tag-ie","tag-ireland","tag-jet-propulsion-laboratory","tag-kennedy-space-center","tag-launch-services-office","tag-launch-services-program","tag-nancy-grace-roman-space-telescope","tag-science","tag-space"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/599602","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=599602"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/599602\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/599603"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=599602"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=599602"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=599602"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
