NASA calls off mission to rescue Swift gamma-ray observatory
NASA and Katalyst Space Technologies announced Wednesday they are giving up on a robotic mission to rescue the Swift gamma-ray telescope before it falls out of orbit. The rescue satellite, named Link, launched July 3 on a journey to fly up to NASA's Neil Gehrels Swift Observatory, capture it with three robotic arms, and boost its orbit high enough to escape a looming reentry. Link is about the size of a refrigerator, with two power-generating solar arrays and three xenon-fueled electric thrusters to send Swift into a safer, higher orbit. Katalyst, the startup leading the Swift rescue effort, said Wednesday that "ongoing attitude control issues" will prevent the Link satellite from completing its rescue mission. The spacecraft is still alive, and Katalyst said it will make the most of Link's remaining capacity, which may still allow it to get near enough to Swift for a demonstration of the satellite's close-in navigation system.

Without a rescue, NASA’s Swift Observatory is expected to reenter the atmosphere later this year.
“While the mission will not have the ending we originally intended, NASA and Katalyst are assessing what milestones remain ahead,” Katalyst said in a statement. “We will continue working to extract technical and operational value from the spacecraft.”
The Swift rescue mission was always risky. NASA awarded Katalyst a $30 million contract less than a year ago to build and launch the Link satellite. NASA said Katalyst had to launch the rescue mission by this summer in order to reach Swift before it falls back into Earth’s atmosphere and burns up.
