  "account": "NASA's Neil Gehrels Swift Observatory has concluded its operations, bringing to an end a remarkable mission marked by innovation and an abundance of scientific discoveries. The spacecraft is anticipated to re-enter Earth's atmosphere within the coming weeks. As with most satellites in low Earth orbit, Swift faced the inevitable force of atmospheric drag. Recent solar activity amplified this effect on the observatory, causing it to begin its descent more swiftly than expected. Despite an attempt to boost Swift in August through a high-risk, rapid-response mission, the spacecraft was not successful in altering its re-entry trajectory.\n\nFollowing the unsuccessful boost mission, Swift resumed its scientific pursuits, having initially paused operations to reduce drag and extend its time in orbit to facilitate the intended boost. Over the subsequent period, the observatory has meticulously observed hundreds of celestial targets, spanning from the aftermath of stellar explosions to the heart of active supermassive black holes in distant galaxies and even comets within our own solar system. This renewed activity, however, further increased the drag on Swift, prompting its rapid descent once more.\n\nOn October 20, Swift reached an altitude of 171 miles (275 kilometers), a point at which the spacecraft's ability to counteract the intensified drag effects ceased. In response, the operations team at Penn State University, in University Park, issued a command to the spacecraft, effectively terminating all Swift operations to ensure a controlled and safe re-entry. For the latest updates on Swift's final journey, readers can follow the Swift blog at https://science.nasa.gov/blogs/swift. This marks the conclusion of the Swift Mission.",
