NASA’s Swift Satellite Telescope Heads for Fiery Re-entry 22 Years After Launch
Why in the News?
NASA's premier $500 million multi-wavelength space telescope, the **Neil Gehrels Swift Observatory**, weighing approximately 3,200 lbs (1,452 kg), re-entered Earth's atmosphere, marking the end of its 22-year mission.
Key Features / Major Points:
- Orbital Decay & Re-entry:
- Lacking its own propulsion system, Swift tumbled out of low-Earth orbit at speeds around 17,000 mph (27,359 kph).
- US Space Force estimated the risk of fragments causing harm to anyone on Earth at less than 1 in 2,100.
- Unsuccessful Robotic Rescue Attempt:
- In July 2026, NASA and startup Katalyst Space Technologies launched the **LINK** servicing spacecraft to dock with Swift and boost it to a higher orbit.
- Attitude control failures rendered the LINK spacecraft uncontrollable, forcing mission managers to abandon the reboost attempt.
- Science Legacy of Swift Observatory:
- Launched in November 2004, Swift was built to study **Gamma-Ray Bursts (GRBs)**—the most energetic explosions in the universe.
- Equipped with three co-aligned telescopes (UV, Optical, and X-ray), it expanded our understanding of supermassive black holes, supernovae, stars, and comets.
