Swift telescope resumes science after failed orbital boost mission

NASA's Neil Gehrels Swift Observatory has resumed science observations with the XRT and UVOT after a private rescue mission failed to boost its orbit, leaving the Burst Alert Telescope offline. With no propulsion, Swift's orbit continues to decay, and NASA says boosting Swift is off the table; the agency now expects the observatory to reach a critical altitude in 1–2 months and likely reenter later this year, while it continues to scan the cosmos and issue alerts from its remaining capabilities.

LINK Battles Spin as NASA Tries to Save Swift Observatory

NASA's LINK spacecraft, built to dock with and tug the Swift Observatory into a higher orbit, is having attitude-control problems and is spinning, disrupting communications. Two of its three reaction wheels are nonfunctional and its cold-gas thrusters have degraded, but ground teams plan to use electric propulsion to stop the spin and reestablish guidance so a rendezvous with Swift can be reassessed; the mission remains active as Swift continues to decay due to increased atmospheric drag from solar activity.
