NASA has announced the conclusion of the scientific mission of the Neil Gehrels Swift Observatory. The satellite has descended to an orbit below 171 miles (275 kilometers) above Earth's surface, where enhanced atmospheric drag prevents the spacecraft's telescopes from stably maintaining astronomical targets in their field of view. Swift conducted its final scientific observation on October 20. During its operational period, the observatory made significant contributions to space exploration, helping scientists track gamma-ray bursts, supernova explosions, and other transient astronomical phenomena. Data collected by the spacecraft formed the basis for numerous scientific publications and discoveries in astrophysics. NASA specialists note that despite the conclusion of the active observation phase, the mission's data archive will continue to be used by the scientific community for further research. The orbital decay is a natural process for satellites in low Earth orbits due to the gradual effects of the atmosphere. Agency engineers will continue to monitor the spacecraft's trajectory as it continues to descend.
