UPDATE: NASA’s Neil Gehrels Swift Observatory re-entered Earth’s atmosphere on Wednesday, nearly 22 years after its launch.
The U.S. Space Force confirmed the telescope re-entered at 7:39 a.m. EST over Indonesia’s North Sumatra region, near 3.4 degrees north latitude and 98.6 degrees east longitude. Most of the spacecraft was expected to burn up in the atmosphere, though NASA said some components may have survived.
NASA’s Neil Gehrels Swift Observatory, a 3,200-pound space telescope, was expected to re-enter Earth’s atmosphere on Wednesday, November 4. The satellite was launched on November 20, 2004, for what NASA originally planned as a two-year mission. However, it spent nearly 22 years observing more than 2,000 gamma-ray bursts, studying black holes, and observing more than 1,400 supernova explosions.
Failed Rescue Attempt
In an attempt to rescue the satellite, NASA launched a $30 million commercial rescue mission in July 2026. The mission used a robotic spacecraft called LINK, which Katalyst Space Technologies developed. The plan was for the spacecraft to capture Swift and raise it to a higher orbit. However, LINK experienced a control system malfunction in August, ending the rescue attempt before LINK could reach Swift.
Swift made its final science observation and entered safe mode on October 20. This “kill-switch” command shut off the satellite’s transmitter. This aims to prevent the pressurized batteries from exploding upon atmospheric impact. If onboard batteries were not switched off, a cloud of dangerous micro-space debris could form for other low-Earth orbit satellites.
Re-entry Timing and Potential Impact Zones
The satellite lost altitude more quickly because of intense solar storms over the past couple of years. These storms heated the upper atmosphere and increased drag on the satellite, pulling the satellite closer to Earth. A major chunk of the minibus-sized observatory is likely to vaporize and burn up in the atmosphere. Scientists note that approximately 10% of its mass could survive rentry. This mass will include dense tungsten pieces, reaction wheels, and mirror components.
Forecasters expected re-entry on Wednesday, November 4, 2026, though estimates varied and the exact time remained uncertain. To estimate where debris could land, forecasters take into account Swift’s orbit, which is tilted 20.6 degrees to the equator. The satellite’s potential debris path lies entirely within a belt ranging from 20.6 degrees north to 20.6 degrees south of the equator. This path includes parts of South and Central America, central Africa, southern India, Southeast Asia, northern Australia.
NASA notes that the risk to people on the ground is low. According to NASA, the U.S. Space Force estimated the odds of a piece of debris injuring anyone on Earth at 1 in 2,100. Moreover, regions farther north or south of this belt, including the continental United States and the UK, lie outside the projected debris zone.
