NASA launches robotic mission from the Marshall Islands to rescue falling Swift telescope

NASA has launched a robotic spacecraft from the Marshall Islands in an attempt to prevent the ageing Swift Observatory from burning up in the atmosphere. The mission, described as unprecedented, is designed to rendezvous with the telescope in orbit and raise it to a higher altitude. If successful, it could also demonstrate a new way to extend the life of other satellites.

The Link spacecraft was launched on Friday at 0836 GMT from an atoll in the Pacific Ocean aboard a Pegasus rocket released from the belly of a modified aircraft. Northrop Grumman carried out the launch, while the spacecraft itself was built by United States-based Katalyst Space Technologies for NASA. The launch had originally been planned for Tuesday but was delayed by weather and then technical issues.

NASA says the operation is expected to take several months and will involve a series of complex steps. Link is due to reach Swift in about a month, after which it will deploy its solar panels, run checks, locate the telescope, circle it and dock using three robotic arms. The final stage would be to push Swift about 300 kilometres higher, roughly back toward its original orbital position.

The agency has put the cost of the effort at about $30 million. Swift, launched in 2004, studies gamma-ray bursts, which are among the most powerful explosions in the universe. According to NASA, the telescope is descending faster than before because of recent solar storms.

That makes the mission both time-sensitive and technically significant, since the spacecraft is trying to reach an ageing satellite that is already losing altitude. The attempt is being watched closely because it could shape future approaches to satellite servicing and rescue. The mission also reflects a broader shift in space operations, where robotic servicing is increasingly seen as a way to protect expensive assets in orbit.

Swift is a $250 million telescope, and the effort to save it comes after more than two decades in space. NASA officials have described the operation as a series of firsts, underlining the difficulty of docking with and moving a satellite that was not designed for this kind of intervention. What remains unclear is whether Link will complete each stage of the rendezvous and docking sequence without incident.

The next major milestone is expected to come when the spacecraft reaches Swift in about a month, followed by the attempt to attach and raise the telescope's orbit. The outcome will determine whether the mission becomes a model for future satellite rescue work or a one-off experiment in orbital repair.
