NASA's Swift Observatory, launched in 2004, is predicted to re-enter Earth's atmosphere on November 4, 2026, at 3:30 a.m. EST, with an uncertainty of 11 hours, according to NASA and the U.S. Space Force.

The Swift Observatory, a 3,200-pound spacecraft, has been monitoring sudden, powerful events in space for over two decades. Its re-entry is expected to occur after a failed rescue attempt left it in a lower orbit.

Most of the spacecraft is expected to burn up in the atmosphere, though some pieces, including denser-than-lead tungsten and mirror parts, could survive re-entry, according to NASA's Brad Cenko, the mission's chief scientist.

The risk of harm to anyone on Earth is considered unlikely, with a chance of about 1 in 2,100, according to the agency.

The Swift Observatory's re-entry zone includes swaths of Africa, Australia, India, Southeast Asia, and Central and South America.

The Swift Observatory was launched in 2004 to study gamma-ray bursts, flashes of high-energy light produced by some of the universe's most powerful explosions.

The Swift team is mourning the loss of the telescope but expresses gratitude for the observations it made during its 22 years in orbit.

NASA's James Webb Space Telescope recently released a new 223-megapixel composite featuring about 16.5 million stars that have been evolving over several million years.

Features of interest for the Nancy Grace Roman Space Telescope include the Large Magellanic Cloud dwarf galaxy and the star cluster NGC 6811 in the constellation Cygnus.

NASA has set a total mission cost of $4.3 billion for the Nancy Grace Roman Space Telescope, which is planned to operate for at least a decade.

NASA and the U.S. Space Force will continue to monitor the re-entry and update predictions.
