NASA’s Neil Gehrels Swift Observatory, a space telescope that studied gamma-ray bursts and other cosmic events, re-entered Earth’s atmosphere at 7:39 a.m. Eastern time on Nov. 4 over Indonesia’s North Sumatra province, ending a mission that lasted nearly 22 years [nasa.gov][reuters.com][dw.com]. The U.S. Space Force reported the re-entry location; NASA said most of the roughly 1,452-kilogram observatory was expected to burn up. The agency reported no damage or injuries on the ground after estimating the chance of debris harming anyone at about 1 in 2,100 [reuters.com][nasa.gov]. Swift launched in 2004 for a planned two-year mission. It detected more than 2,000 gamma-ray bursts, observed more than 1,400 supernovae and contributed data to about 7,000 scientific papers [science.org][reuters.com]. Its rapid alerts also let other observatories follow up on short-lived events [nasa.gov][scientificamerican.com]. Solar activity swelled Earth’s upper atmosphere, increasing drag on Swift, which had no propulsion system to raise its orbit [reuters.com][dw.com]. A NASA-backed rescue attempt failed after the robotic spacecraft LINK lost control and began spinning. Swift ended science operations on Oct. 20 [reuters.com][theconversation.com]. Researchers can continue working with the telescope’s archived observations [livescience.com]. Highlights: • Rapid response: Swift could turn across 50 degrees of sky in less than 75 seconds, allowing it to observe transient events while their afterglows were still visible [theconversation.com]. • Microlensing collaboration: In 2015, Swift teamed up with two other telescopes to observe a brown dwarf passing in front of a more distant star; the distortion of the star’s light helped researchers determine the brown dwarf’s size and mass [science.org]. • Early supernova signal: In 2008, Swift detected a rise in X-rays before a supernova explosion, capturing an early phase of supernova evolution [theconversation.com]. • Unexpected flare: Swift detected a 2014 gamma-ray flare from interacting binary stars that researchers considered a possible candidate for the brightest event seen from a red dwarf [science.org]. Perspectives: NASA: NASA Administrator Jared Isaacman said the agency should consider every reasonable option to keep the Hubble Space Telescope operating because it still has important science ahead [pbs.org]. (PBS NewsHour (Associated Press)) Katalyst Space Technologies: The company said LINK no longer had enough propellant to capture Swift and raise its orbit safely after engineers worked to slow the spacecraft’s uncontrolled spin [theconversation.com]. (The Conversation) Dean Sladen: The aerospace engineer argued that designing satellites for safe re-entry is increasingly important as the long-term risk of re-entry accidents grows [reuters.com].
