Audacious mission to rescue NASA's falling telescope has launched

NASA launched the LINK spacecraft, built by Katalyst Space Technologies, to rescue the Neil Gehrels Swift Observatory from orbital decay. The three-armed robot launched July 3 on a Pegasus XL rocket from Kwajalein Atoll. LINK will grab Swift and push it from 375 kilometers back to its original 600-kilometer altitude, extending its life by up to a decade.
