In this story
A capability has returned
NASA says its Neil Gehrels Swift Observatory has resumed using the Burst Alert Telescope and automatically redirecting its other telescopes toward new high-energy flashes. The September 25 update reports that the gamma-ray instrument was calibrated and detecting on September 18; automatic pointing resumed September 21.
The operating tradeoff
The agency says the return to science follows a scaled-back commercial boost effort. Swift is approximately 200 miles above Earth, and its team estimates that operations will become more difficult below about 185 miles.
The update projects that threshold for early to mid-October. That is an estimate, not a confirmed shutdown date.
What to watch next
For readers following astronomy from home or a classroom, the story is both the observations and the engineering constraints that make them possible. Follow the mission’s next dated update before repeating a prediction as a completed event.
Restoring an instrument is a real milestone; it does not erase the orbital limit described in the same report.
Sources & verification
September 25, 2026 update; September 18 instrument verification, September 21 automatic pointing, approximate altitude and projected early/mid-October operational threshold.
