NASA\u2019s Swift satellite telescope, which spent two decades studying the most powerful known blasts \u200bof energy in the cosmos, tumbled out of orbit as expected<\/a> on Wednesday and burned up in Earth\u2019s \u200catmosphere over Indonesia, the space agency reported.<\/strong><\/p>\n

The fiery demise of the Neil Gehrels Swift Observatory, weighing roughly 3,200 pounds, came less than three months after a rescue spacecraft failed its mission<\/a> to boost the satellite to a higher orbit and extend its life.<\/p>\n

The US Space Force confirmed \u200bthat Swift\u2019s re-entry occurred at 7:39am, as the satellite streaked into the upper atmosphere at \u200babout 22 times the speed of sound over Indonesia\u2019s North Sumatra province, roughly 200 miles north of the equator, according to NASA.<\/p>\n

NASA said it expected the frictional heat of re-entry would incinerate most of \u200bthe satellite well above Earth\u2019s surface, with some fragments surviving the plunge, though the US space agency reported no damage or \u200binjuries on the ground from falling debris.<\/p>\n

It was not immediately clear how close the telescope\u2019s re-entry point was to North Sumatra\u2019s capital and largest city, Medan, home to about 2.5 million people. The population of the province as a whole totals around 16 million.<\/p>\n

The Space Force \u200bhad earlier calculated the risk posed to populated areas as very low, putting the odds of harm coming to anyone \u200bon Earth at one chance in 2,100.<\/p>\n

Dean Sladen, an aerospace engineer for Britain-based industrial parts supplier Accu Components, said before re-entry that \u200conly \u2060a \u201chandful of small, scorched fragments are expected to make it down, nothing recognisable as a telescope.\u201d<\/p>\n

\u201cSatellites this size re-enter the atmosphere regularly, and in nearly 70 years of spaceflight no one has ever been killed by falling debris,\u201d Sladen said in an email.<\/p>\n

The risk of a re-entry accident grows over the longer term, \u201cwhich is why designing satellites to come down safely matters \u200bmore and more,\u201d he added.<\/p>\n

NASA\u2019s \u200bprized $500 million Swift satellite \u2060was primarily designed to study gamma-ray bursts – the most intense blasts of energy in the universe – using its multi-wavelength array of three telescopes.<\/p>\n

Since its launch in 2004, Swift has also studied \u200bhundreds of supernova explosions, star-shredding black holes, stellar X-ray flares, asteroids and comets, contributing to \u200bsome 7,000 \u2060published scientific papers. It ceased operations on October 20.<\/p>\n

The observatory, which lacked its own propulsion system, had long outlasted its two-year design life and had been drifting toward orbital instability for months.<\/p>\n

In July, NASA and Arizona-based startup Katalyst launched a specially built rescue \u2060vehicle called \u200bLINK on a mission to rendezvous with Swift, latch onto the satellite \u200b, and tug it into a higher, more sustainable orbit.<\/p>\n

But the LINK spacecraft itself began spinning uncontrollably soon after reaching space, and by mid-August, mission managers \u200babandoned the effort, resigned to letting Swift fall back to Earth.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
