CAPE CANAVERAL, Fla. — The spacecraft rushing to the rescue of an aging and sinking NASA telescope has run into its own problem. The trouble struck over the weekend, three weeks after the three-armed robotic spacecraft blasted into orbit, AP reported. The startup company said it’s working nonstop to get Link back in action so it can capture Swift and boost the telescope to a higher orbit. NASA is paying $30 million for the rescue effort, which was thrown together in under a year. “The mission remains active and we continue to believe that with these changes, Link has a viable path to rendezvous with Swift,” Katalyst said in a statement.
