NASA Launches High Risk Mission to Rescue Swift Telescope Before It Falls Back to Earth

In a daring effort to save one of its longest serving space observatories, NASA has launched a rescue mission to prevent the Swift Observatory from falling back to Earth. The ambitious operation, being carried out with Katalyst Space Technologies and Northrop Grumman , aims to extend the life of the ageing telescope, allowing it to continue studying some of the universe's most powerful cosmic explosions.

The mission began on Friday when Katalyst's Link spacecraft was successfully launched aboard a Pegasus rocket from the Marshall Islands in the Pacific Ocean. Unlike conventional rockets, Pegasus was released from the belly of a specially modified aircraft before igniting its engines and heading into orbit. The spacecraft is expected to reach the Swift Observatory in about a month.

Launched in 2004 , Swift has spent more than two decades observing gamma ray bursts , exploding stars and other energetic events across the universe. However, recent solar storms have increased atmospheric drag, causing the telescope to lose altitude much faster than expected. It is currently orbiting around 360 kilometres above Earth , and scientists estimate that without intervention it could re enter Earth's atmosphere and burn up by October .

To prevent that outcome, NASA is investing USD 30 million in the rescue mission. Once Link reaches Swift, its three robotic arms will carefully capture the observatory before using onboard thrusters to gently raise its orbit by about 240 kilometres . The slow and controlled manoeuvre is designed to avoid damaging the telescope's sensitive scientific instruments.

Scientists have temporarily paused Swift's observations to preserve its remaining orbital altitude. If the mission succeeds, the telescope is expected to resume scientific operations by September .

The operation is also a major milestone for the growing commercial space servicing industry . Katalyst Space Technologies assembled the mission in just nine months after receiving NASA's urgent request. A successful rescue could also provide a blueprint for future missions, including a possible orbit boosting operation for the Hubble Space Telescope , which is facing similar altitude loss due to increased atmospheric drag. The mission could mark a new era in extending the lifespan of valuable scientific spacecraft.
