NASA's doomed Swift space telescope restarts science work after rescue mission fails

NASA's Neil Gehrels Swift Observatory is back to studying the universe after spending months in a low-drag configuration while awaiting an orbital rescue mission that ultimately fell short.Mission controllers restarted two of Swift's three science instruments — its X-ray Telescope (XRT) and Ultraviolet/Optical Telescope (UVOT) — on Aug. 26. Both instruments had been shut down in February as part of an effort to minimize atmospheric drag and keep the aging spacecraft in orbit long eno
