A rescue mission to salvage NASA’s Neil Gehrels Swift Observatory from an impending atmospheric re-entry successfully launched on Friday, marking a critical step in extending the telescope’s operational lifespan.
NASA is racing to reposition the 1.6-ton spacecraft before orbital decay due to atmospheric drag leads to its destruction in the coming months.
The refrigerator-sized rescue vehicle, Link, developed by Katalyst Space Technologies of Flagstaff, Arizona, aims to grapple Swift and elevate it to a higher orbit, enabling continued observations of gamma-ray bursts—high-energy phenomena linked to cosmic events like stellar collisions.
After three prior launch delays—two due to adverse weather and one from technical issues—Link was deployed via Northrop Grumman’s Pegasus XL rocket, carried under a modified Lockheed L-1011 aircraft from Kwajalein Atoll in the Marshall Islands.
The rocket was released at 40,000 feet altitude at 4:36 a.m. Eastern time, with its engines igniting shortly after to propel Link into space. Ground control has since verified communication with the spacecraft and initiated system checks.
Link is expected to reach Swift in approximately six weeks, then gradually maneuver it to a 100-mile-high orbit over two months—a adjustment sufficient to prolong its mission for roughly another decade.
Originally launched in 2004 with a two-year design life, Swift has exceeded expectations but faces accelerated orbital decay due to increased atmospheric drag from heightened solar activity during the Sun’s 11-year sunspot cycle peak.
Under a $30 million contract, NASA deemed the risky endeavor viable as Swift remains functional, while constructing a replacement would require significantly more time and resources.
