NASA's Swift Observatory set to plunge back to Earth this week

Key Points:

• NASA's Swift Observatory, launched in 2004 to study gamma-ray bursts, is expected to make an uncontrolled reentry into Earth's atmosphere in early November 2026 after more than two decades in space.
• A pioneering commercial mission in 2026 aimed at rescuing and boosting the telescope to a higher orbit failed when the LINK spacecraft could not successfully capture Swift.
• Most of the satellite will burn up during reentry, but some fragments may survive and fall into the ocean or sparsely populated regions within 21 degrees of the equator, including parts of Africa, South and Southeast Asia, and Latin America.
• The observatory's descent poses minimal risk to people, as satellites of this size frequently reenter Earth's atmosphere without causing harm, with no recorded fatalities from space debris in nearly 70 years of spaceflight.
• Prior to the end of the rescue mission, NASA resumed Swift's scientific observations, maximizing data collection before its impending fall from an orbit as low as 171 miles, significantly below the International Space Station's altitude.
