A NASA space observatory is at risk of reentering Earth's atmosphere after a rescue effort fell short. The Neil Gehrels Swift Observatory, which is decades old, has been steadily losing altitude. A satellite called LINK was launched to boost the observatory's orbit, but it encountered difficulties, including spinning out of control, just weeks after its July 3 launch.

The issue was resolved, but the delay has pushed back the LINK satellite's rendezvous with the observatory. This postponement has ultimately hindered the rescue mission.

Further details on the mission and the observatory's status are available from the source.
