NASA’s 22-year-old Swift satellite telescope falls from orbit in fiery finale
WASHINGTON –
asserted
telescope → fall → finale
NASA’s Swift satellite telescope, which spent two decades studying the most powerful known blasts of energy in the cosmos, tumbled out of orbit as expected on Nov 4 and burnt up in Earth’s atmosphere over Indonesia, the space agency reported.
asserted
agency → spend → Indonesia
The fiery demise of the Neil Gehrels Swift Observatory, weighing roughly 1,452 kg, came less than three months after a rescue spacecraft failed its mission to boost the satellite to higher orbit and extend its life.
asserted
spacecraft → weigh → life
The US Space Force confirmed that Swift’s re-entry occurred at 7.39am EST (8.39pm Singapore time), as the satellite streaked into the upper atmosphere at about 22 times the speed of sound over Indonesia’s North Sumatra province, roughly 322 km north of the equator, according to NASA.
uncertain
satellite → confirm → NASA
NASA said it expected the frictional heat of re-entry would incinerate most of the satellite well above Earth’s surface, with some fragments surviving the plunge, though the US space agency reported no damage or injuries on the ground from falling debris.
asserted
agency → say → debris
The population of the province as a whole totals around 16 million.
asserted
population → total → million
The Space Force had earlier calculated the risk posed to populated areas as very low, putting the odds of harm coming to anyone on Earth at one chance in 2,100.
asserted
harm → calculate → 2,100
Dean Sladen, an aerospace engineer for Britain-based industrial parts supplier Accu Components, said prior to re-entry that only a “handful of small, scorched fragments are expected to make it down, nothing recognisable as a telescope”.
asserted
handful → base → telescope
“Satellites this size re-enter the atmosphere regularly, and in nearly 70 years of spaceflight no one has ever been killed by falling debris,” Sladen said in an e-mail.
asserted
Sladen → re → mail
The risk of a re-entry accident grows over the longer term, “which is why designing satellites to come down safely matters more and more”, he added.
asserted
he → grow → satellites
NASA’s prized US$500 million (S$640 million) Swift satellite was primarily designed to study gamma-ray bursts – the most intense blasts of energy in the universe – using its multi-wavelength array of three telescopes.
asserted
satellite → prize → telescopes
Since its launch in 2004, Swift had also studied hundreds of supernova explosions, star-shredding black holes, stellar X-ray flares, asteroids and comets, contributing to some 7,000 published scientific papers.
asserted
Swift → study → papers
It ceased operations on Oct 20.
asserted
It → cease → Oct
The observatory, which lacked its own propulsion system, had long outlasted its two-year design life and had been drifting towards orbital instability for months.
asserted
which → lack → months
In July, NASA and Arizona-based start-up Katalyst launched a specially built rescue vehicle called LINK on a mission to rendezvous with Swift, latch onto the satellite and tug it into a higher, more sustainable orbit.
asserted
NASA → base → orbit
But the LINK spacecraft itself began spinning uncontrollably soon after reaching space, and by mid-August, mission managers abandoned the effort, resigned to letting Swift fall back to Earth.
asserted
Swift → begin → Earth
