A NASA space telescope that was designed to explore cosmic explosions in deep space has crashed back to Earth, after a failed rescue attempt.<\/p>\n

The US space agency says its Neil Gehrels Swift Observatory re-entered Earth\u2019s atmosphere on Wednesday 4 November 2026, nearly 22 years after launch.<\/p>\n

The spacecraft re-entered Earth\u2019s atmosphere at 07:39 EST (12:39 UTC), breaking up over the North Sumatra region of Indonesia.<\/p>\n

NASA says most of the space observatory will have burned up as it slammed into our planet’s thick atmosphere, but some parts may have survived re-entry.<\/p>\n

The mission to explore explosions in space<\/p>\n

Launched on November 20, 2004, Swift was placed into orbit around Earth and was originally designed as a short-term, two-year mission.<\/p>\n

Its primary purpose was to solve one of astronomy\u2019s greatest mysteries: gamma-ray bursts<\/a> (GRBs). <\/p>\n

These strong flashes are among the most powerful explosions in the Universe and produce heavy bursts of the most energetic form of light, known as gamma rays.<\/p>\n

They’re thought to be caused by either the deaths of giant stars or the collisions of neutron stars<\/a>, but they vanish almost as quickly as they appear, often lasting only a few seconds.<\/p>\n

However, scientists have discovered much longer bursts, including an incredible seven-hour gamma ray burst<\/a>.<\/p>\n

The Neil Gehrels Swift Observatory was equipped with three telescopes spanning different wavelengths of light.<\/p>\n

It could automatically detect a gamma-ray burst and turn to observe it, alerting scientists and ground-based telescopes around the globe to follow up with more observations.<\/p>\n

The space telescope’s two-year mission turned into a nearly 22-year marathon.<\/p>\n

Over two decades, Swift tracked gamma ray bursts but also observed comets and asteroids in our own Solar System, supermassive black holes in distant galaxies and X-ray flares from active stars.<\/p>\n

\nThe mission to rescue the Swift telescope<\/p>\n

Satellites in low earth orbit travel through the outer layers of Earth\u2019s atmosphere.<\/p>\n

As a result, the constant drag of our planet’s thick atmosphere slowly pulls their orbit lower and lower. This is known as ‘orbital decay’.<\/p>\n

Swift\u2019s orbit eventually decayed past the point of recovery, prompting NASA to conclude its science operations.<\/p>\n

Earlier in 2026, NASA attempted a rescue mission whereby a spacecraft was sent to rendezvous with Swift and boost it to a safer, higher orbit.<\/p>\n

Technical issues prevented the spacecraft from executing the manoeuvre, leaving gravity to take its course.<\/p>\n

\nA lasting legacy<\/p>\n

“Swift delivered an incredible, lasting return on investment for the nation, designed for a two-year primary mission but productive for more than 10 times as long,” says Shawn Domagal-Goldman, director, Astrophysics Division at NASA Headquarters in Washington.<\/p>\n

“In that time, Swift played a major role in advancing our understanding of the changing universe and was part of a revolution in astrophysics that showed how critical rapid-response observations are to the entire community.<\/p>\n

“To support rapid response to cosmic events in a post-Swift world, we\u2019re exploring our ability to use and augment NASA\u2019s fleet of existing space telescopes, from fast-to-orbit commercial capabilities to efficient, innovative new missions.<\/p>\n

“And Swift leaves us with an extraordinary archive of multiwavelength observations that will fuel new discoveries for decades more.”<\/p>\n","protected":false},"excerpt":{"rendered":"A NASA space telescope that was designed to explore cosmic explosions in deep space has crashed back to…\n","protected":false},"author":2,"featured_media":675591,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[61,60,82,247],"class_list":["post-675590","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-ie","tag-ireland","tag-science","tag-space"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/675590","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=675590"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/675590\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/675591"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=675590"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=675590"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=675590"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
