Nasa’s Swift Observatory Set for Return After 22 Years in Orbit

WHO:

CBS News - NASA’s Swift Observatory is an aging space telescope; NASA’s Brad Cenko is the mission’s chief scientist.

CBS News - John Nousek, an astronomer at Pennsylvania State University who led Swift’s control team, said the telescope’s eventual return was expected and that “what goes up must come down.”

CBS News - NASA hired Katalyst Space to attempt a rescue. Its three-armed robot, Link, failed to reach Swift and later returned to Earth.

CBS News - Shawn Domagal-Goldman, NASA Astrophysics Division director, said Swift uniquely identifies gamma-ray bursts.

WHAT:

CBS News - NASA predicted Swift would re-enter Earth’s atmosphere on Wednesday. Most of the roughly 1½-ton (3,200-pound) observatory is expected to burn up; some dense tungsten pieces and mirror parts could survive.

CBS News - NASA estimated the risk of harm to anyone on Earth at roughly 1 in 2,100. Any surviving wreckage is most likely to fall into the ocean.

CBS News - Swift completed 22 years in orbit and recorded more than 2,000 gamma-ray bursts and 1,400 exploding stars, along with comets, asteroids, and star-shredding black holes.

CBS News - Swift resumed observations after the rescue attempt was abandoned, but was shut down when it became too low to remain steady.

CNET - Most of Swift is expected to burn up during atmospheric re-entry, though some fragments may reach Earth.

WHERE:

CBS News - The re-entry zone includes parts of Africa, Australia, India, Southeast Asia, and Central and South America; the U.S. Space Force is tracking the spacecraft.

CBS News - Swift was launched to search the universe for gamma-ray bursts and supernovas.

WHEN:

CBS News - The U.S. Space Force forecast re-entry at approximately 3:30 a.m. EST on Nov. 4, with an uncertainty of 11 hours.

CBS News - Swift launched on Nov. 20, 2004. Link launched in July and plunged back to Earth in September; Swift was shut down by late October.

WHY:

CBS News - Intense solar activity over the past few years accelerated Swift’s orbital descent.

CBS News - The attempted rescue was intended to address Swift’s declining orbit; Link’s trouble left it no closer than 7 to 9 miles from the telescope.

HOW:

CBS News - NASA and the U.S. Space Force are monitoring Swift’s re-entry and updating predictions.

CBS News - Swift’s ability to swivel quickly toward erupting celestial events made it a first responder for Hubble, Webb, and other telescopes, which could follow its alerts with deeper observations.

CBS News - NASA and scientists are considering how to fill the gap left by Swift and apply lessons from its mission to future space missions.

NASA’s Swift telescope is expected to re-enter Earth’s atmosphere Wednesday, mostly burning up. For 22 years, it swiftly identified gamma-ray bursts and alerted other telescopes. NASA says any surviving fragments will most likely fall into the ocean.
