NASA ends Swift observatory science mission as orbit decays
NASA has concluded the science operations of the Neil Gehrels Swift Observatory after atmospheric drag dropped the uncrewed satellite below 171 miles in altitude.

NASA News and BGNES reported on Oct. 23 that NASA has ended the 20-year science mission of the Neil Gehrels Swift Observatory. The uncrewed satellite is currently orbiting at an altitude of less than 171 miles, or 275 kilometers, above Earth. Increased atmospheric drag at this low altitude prevents the spacecraft from steadily pointing its telescopes at astronomical targets. [1][2]
The observatory performed its final scientific observation on Oct. 20, according to NASA News. NASA expects the spacecraft to re-enter Earth's atmosphere within the next few weeks. [1]
An effort called the Swift boost mission attempted to extend the lifetime of the observatory. The LINK servicing spacecraft, built and operated by Katalyst Space Technologies, launched on July 3, 2026, to boost Swift's orbit, but the servicing spacecraft re-entered the atmosphere on Sept. 25, 2026. [7]
The spacecraft will now complete an uncontrolled re-entry as atmospheric drag causes its remaining orbit to decay completely over the coming weeks. [1][7]
In short
- NASA concluded science operations for the Neil Gehrels Swift Observatory after 20 years.
- Swift conducted its final astronomical observation on Oct. 20.
- Atmospheric drag below 171 miles prevented the satellite from steadily targeting astronomical objects.
- The spacecraft is expected to re-enter Earth's atmosphere within a few weeks.
