  "account": "Nearly 22 years after its launch, NASA's Swift satellite telescope is set to re-enter Earth's atmosphere and burn up in a fiery descent, according to the space agency. The aging Neil Gehrels Swift Observatory, weighing around 3,200 pounds, was intended to be retrieved in a failed rescue mission this summer. The US Space Force estimates a one-in-2,100 chance of harm to anyone on Earth due to the re-entry, with the event expected to occur around 3:30am EST (0830 GMT). Aerospace Corporation and a London-based astrophysicist project a slightly different re-entry window of 5:19am EST (0819 GMT) and 7:45am EST (1245 GMT) respectively. The satellite, which has been drifting in a circular orbit for months, was originally designed for a two-year mission studying gamma-ray bursts and other cosmic phenomena. Its mission has been extended since 2004, utilizing its three telescopes, but it lacks onboard propulsion. Efforts to prolong Swift's life through a rescue mission were ultimately abandoned in mid-August due to technical issues with the rescue spacecraft.",
  "summary": "An aging Nasa satellite telescope that a robotic spacecraft was sent to retrieve on a failed rescue mission this summer was headed for a fiery re-entry into Earth’s atmosphere on Wednesday, nearly 22 years after it was launched into orbit. The Neil Gehrels Swift Observatory , weighing roughly 3,200 pounds (1,452 kg), was set to tumble out of orbit and burn up in the atmosphere somewhere over the…",
