NASA telescope is on the verge of plunging back to Earth after failed rescue mission

CAPE CANAVERAL, Fla. — Ailing NASA Swift Observatory, a telescope launched in 2004 to observe cosmic phenomena, is set to return to Earth after a rescue mission failed. The U.S. Space Force anticipates the 1.5-ton spacecraft to re-enter the atmosphere on or around Friday. Most of the telescope is expected to disintegrate upon re-entry, yet a few dense tungsten and mirror components may survive, potentially landing in the ocean.

However, regions including parts of Africa, Australia, India, Southeast Asia, and Central and South America lie within the reentry zone.

Swift's demise has been anticipated since before its launch. NASA's Brad Cenko, the mission's chief scientist, revealed that intense solar activity has accelerated its descent. Originally tasked with detecting gamma ray bursts and supernovas, Swift has observed over 2,000 gamma ray bursts and 1,400 exploding stars during its 22-year mission.

Despite a rescue attempt launched a year ago by Katalyst Space, their three-armed robot, named Link, failed to approach the telescope within required proximity. Consequently, a year later, Swift resumed its observations, detecting even more cosmic events. Nonetheless, its low Earth orbit was no longer stable, prompting NASA to shut down its systems.

Swift's unique feature was its rapid swiveling, enabling it to swiftly focus on celestial bursts. NASA recognized Swift as a critical early warning system for other space telescopes, such as Hubble and Webb. Scientists are now grappling with the challenge of replacing Swift's role. John Nousek, an astronomer who led the control team, expressed hope that the lessons learned from Swift's operations can benefit future missions and expedite cosmic discoveries.
