Overview
- NASA confirmed on Tuesday that Swift will reenter Earth uncontrolled in the coming weeks and that mission operations were formally stopped after the telescope’s last observation on October 20.
- Efforts to capture and reboost Swift using Katalyst Space’s robotic vehicle LINK were abandoned in August, a decision that made an uncontrolled descent unavoidable.
- Swift’s tilted low-Earth orbit creates a wide potential reentry band that runs roughly from central Mexico through much of South America, which places Argentina inside the area of possible debris fall but does not mean impact there is likely.
- NASA says most of the spacecraft is expected to burn up during reentry though some dense fragments could survive; the agency assesses the chance of injury or damage to people as low and will refine timing and impact probabilities as tracking continues.
- Launched in November 2004 for a two-year mission, Swift operated for nearly 22 years, produced a public archive used in about 7,000 papers, and leaves a capability gap for rapid detection and follow-up of short-lived cosmic explosions.
