NASA launches rescue mission for space telescope facing Earth crash

NASA is preparing a daring rescue mission to prevent one of its vital space telescopes, the Neil Gehrels Swift Observatory, from plummeting to Earth. The observatory, launched in 2004 to study powerful cosmic events like gamma-ray bursts, has been descending faster than anticipated due to solar storms in 2024.

Scheduled for June 27, the mission involves an uncrewed spacecraft named LINK. This vehicle will attempt to rendezvous with Swift, dock using its three robotic arms, and then propel the telescope into a higher, safer orbit. This maneuver is unprecedented for a space telescope not originally equipped for such an operation, making the undertaking particularly challenging.

Swift is critically important for astrophysics. It can pinpoint gamma-ray bursts within minutes, a capability that allows scientists to conduct rapid follow-up observations. Losing Swift would mean a significant loss of research capacity, as other telescopes require much longer to locate these fleeting cosmic phenomena. The telescope is expected to reach a critical altitude of 300 kilometers by October, after which atmospheric drag could accelerate its descent, leading to a crash before the year's end.

To expedite the development of the rescue vehicle, NASA contracted the American space company Katalyst Space in September 2025, providing them with $30 million. Katalyst Space successfully developed the LINK spacecraft within the ambitious timeframe. The mission's success is not guaranteed, with spaceflight engineer Angadh Nanjangud of Queen Mary University in London acknowledging the numerous potential failure points. However, the rapid development itself is being hailed as a remarkable achievement, demonstrating swift technological response to an urgent need.
