CAPE CANAVERAL, Fla. (AP) — A NASA telescope barely holding on to space after a failed rescue efforts left him totter lower and lower.
THE US Space Force predicts that the Swift Observatory will collapse on or around Friday.
Most of the one and a half ton telescope is expected to burn up in the atmosphere. But a handful of parts made of tungsten denser than lead and some mirror parts could survive reentry, according to NASA’s Brad Cenko, the mission’s chief scientist.
Any surviving wreckage will most likely sink into the ocean. But swaths of Africa, Australia, India, Southeast Asia, and Central and South America are in the re-entry zone. The Space Force follows the telescope’s decreasing trajectory.
His cosmic cremation mourns the Swift team but is full of gratitude for the observations made by the telescope during its 22 years in orbit. Swift took off on November 20, 2004, in search of some of the biggest explosions in the universe: gamma-ray bursts and supernovas.
“We knew this day would come before Swift launched. At least in low Earth orbit, what goes up must come down. And this ending is catastrophic,” said John Nousek of Pennsylvania State University, an astronomer who led the monitoring team.
Intense solar activity over the past few years, has dragged Swift down faster than usual. NASA hired Katalyst Space a year ago to build urgent rescue. But the company’s three-armed robot, Link, ran into problems after launch in July and did not come closer than 7 miles to 9 miles (12 kilometers to 15 kilometers) from the telescope. Link returned to Earth in September.
Swift resumed her observations after the rescue attempt was called off, discovering even more gamma-ray bursts and other very high-energy events. But by the end of October, the telescope was too low to remain stable for observations and its systems were shut down.
Its final tally: more than 2,000 gamma-ray bursts and 1,400 exploding stars, not to mention a slew of comets, asteroids and star-shredding black holes. The telescope’s superpower was its ability to quickly pivot – hence its name – towards erupting celestial events.
NASA viewed Swift as a first responder to the Hubble and Webb space telescopes and others who would follow up on its alerts and provide further investigations. Scientists are still working out how to fill this gap.
“Our fervent hope is that the lessons learned from Swift’s successes can be applied to new generations of space missions to accelerate our discoveries about the universe,” Nousek said in an email.
