# NASA restarts Swift observatory after failed rescue mission

The Neil Gehrels Swift Observatory satellite, now orbiting at 340 kilometers, was re-commanded to resume observations after a July rescue attempt by the unmanned Link spacecraft failed due to malfunctioning attitude control wheels.

NASA has reinstated commands to restart the observation instruments on the Neil Gehrels Swift Observatory satellite, following a failed rescue mission in July 2026.[^2] The unmanned spacecraft named Link was unable to complete its mission because two of its attitude control wheels malfunctioned.[^1]

The Swift satellite is currently orbiting at an altitude of 340 kilometers, having dropped from its initial 600 kilometers.[^3] NASA scientists estimate the satellite will drop below the 300-kilometer safety threshold within this month if observations resume.[^4] The read here is that the clock is tight: the margin between a working observatory and a decaying orbit is now measured in weeks.
