A piece of the wrecked 1986 Challenger space shuttle was found off Florida’s coast

A documentary crew searching the bottom of the Atlantic Ocean off the coast of Florida for a World War II-era wreckage uncovered a very different historical artifact. 

While digging in the seabed, crew members from the History Channel discovered a piece of the 1986 space shuttle Challenger, the explosion of which resulted in the death of all seven astronauts on board mere seconds after liftoff. NASA confirmed the findings in an announcement shared Thursday.

The History Channel posted footage of the dive on Twitter. The short video shows two divers examining a large piece of debris covered with square tiles and embedded in sand. 

The proximity of the object to the Florida Space Coast, a region around the Kennedy Space Center and Cape Canaveral Space Force Station where NASA launches its spaceflights, as well as the item’s perceived modern construction, led the group to contact NASA. Space shuttle artifacts are property of the U.S. government, said Patti Bielling, news chief at NASA’s John F. Kennedy Space Center.

The Challenger exploded just 73 seconds after launch due to a malfunction blamed on the day’s cold temperatures. Its crew consisted of Francis R. “Dick” Scobee, Michael J. Smith, Ronald E. McNair, Ellison S. Onizuka, Judith A. Resnik, Gregory B. Jarvis, and S. Christa McAuliffe (who was a teacher participating in the launch).
