NASA Swift telescope to undergo uncontrolled re-entry

The Neil Gehrels Swift Observatory, a NASA space telescope that has been operational for nearly 22 years, is expected to undergo an uncontrolled re-entry into Earth's atmosphere within the coming weeks. The mission officially concluded on October 20, 2026, after the spacecraft's altitude dropped below 275 kilometers, where atmospheric drag prevented it from maintaining the stability required for scientific observations.

A high-risk rescue attempt by the private company Katalyst Space Technologies failed earlier this year. The company's LINK spacecraft was intended to capture the telescope and boost it to a higher orbit, but the mission was unsuccessful due to propulsion and attitude control failures on the LINK craft.

Launched in November 2004 with an initial two-year lifespan, Swift has far exceeded its design parameters. The observatory has detected over 2,000 gamma-ray bursts and more than 1,400 supernovae, contributing data to approximately 7,000 scientific papers. While most of the structure is expected to disintegrate upon re-entry, NASA notes that some dense fragments may survive. The potential debris path spans a corridor from central Mexico through much of South America and across large oceanic regions, though the agency considers the risk of injury or property damage to be statistically very low.
