Swift Observatory Rescue Mission Fails
NASA has officially ended its mission to rescue the Neil Gehrels Swift Observatory after the commercial spacecraft tasked with the job experienced thruster failures. The telescope, which has monitored high-energy astrophysical phenomena for over two decades, is now expected to burn up in Earth's atmosphere by 2026.
Why it matters
The failure highlights the challenges of commercializing satellite servicing and the potential loss of a critical tool for multiwavelength astronomy.
Earlier this year, NASA announced that one of its powerhouse telescopes, the Neil Gehrels Swift Observatory , was falling from orbit much faster than anticipated. Although Swift’s low-Earth orbit had remained relatively steady for more than 2 decades, unusually strong solar activity in 2024 destabilized it. The agency predicted that the telescope would burn up in Earth’s atmosphere by the end of 2026.
NASA soon after announced a commercial effort by U.S. company Katalyst Space Technologies to rescue the telescope by using another spacecraft to boost Swift’s orbit. The mission launched successfully on 3 July. However, after a month of technological issues with the rescuing craft’s maneuvering thrusters, NASA and Katalyst have pulled the plug on the mission, leaving Swift to its fiery fate.
