NASA Swift observatory expected to burn up in atmospheric reentry

The uncrewed Neil Gehrels Swift Observatory is expected to reenter Earth's atmosphere and burn up on or around Friday, Nov. 6, 2026. SatNews reported that the event follows the failure of a commercial mission to boost the orbital altitude of the NASA astrophysics satellite. SatNews and La Voce di New York both report that the spacecraft is projected to reenter by Friday. [1][7]

SatNews reported that elevated solar activity expanded the upper atmosphere of Earth, causing aerodynamic drag that destabilized the orbit of the satellite. The increased drag pulled the 1,500-kilogram observatory from its nominal 600-kilometer orbit to critical altitudes below 275 kilometers. As a result, the spacecraft has ceased scientific observations in low Earth orbit. [1]

The Neil Gehrels Swift Observatory carries three instruments to study gamma-ray bursts and monitor their afterglows in X-ray, ultraviolet, and visible light. The spacecraft launched on Nov. 20, 2004, aboard a Delta II rocket as a joint partnership between NASA Goddard Space Flight Center and an international consortium from the United States, the United Kingdom, and Italy.

Atmospheric entry involves the movement of an object from space through atmospheric gases. As FTMQ Space reported earlier, NASA concluded science operations for the satellite after drag dropped its altitude below 171 miles, preventing it from steadily targeting astronomical objects. [8][11]
