After more than eighteen years of groundbreaking service observing the high-energy universe, NASA’s Swift spacecraft has officially completed its mission. Throughout its operational life, Swift provided astronomers with crucial real-time data on gamma-ray bursts and other cosmic phenomena, fundamentally transforming our understanding of the dynamic cosmos. As it prepares for controlled re-entry, mission teams have transitioned Swift into a safe descent trajectory to ensure that it will burn up harmlessly in Earth’s atmosphere.

Key achievements of the Swift mission include:

  • Rapid Localization: Pinpointing over 1,300 gamma-ray bursts within seconds to minutes.
  • Multi-wavelength Observations: Capturing data across gamma-ray, X-ray, and ultraviolet/optical wavelengths.
  • Collaborative Science: Enabling hundreds of follow-up observations by space- and…
