Columbia’s First Launch back in 1981 - on that day, it became the first reusable manned spacecraft to travel into space

It was against this backdrop on the morning of Saturday, Feb. 1, 2003, that the Space Shuttle Columbia was lost just 15 minutes before it was scheduled to land at Cape Canaveral. It was the 28th mission for the reusable Columbia, which had inaugurated the shuttle program in 1981, and the 107th overall shuttle mission for NASA.

News broke just after 6 a.m. Pacific Time that NASA had “lost contact” with the Space Shuttle Columbia somewhere over Texas. The notion of “losing contact” with a spacecraft, especially one that lands like a glider, was difficult to reconcile and not like any NASA mission anyone could recall.

The shuttle had broken up somewhere over Texas. NASA explains the circumstantial reason behind the incident, foam from the shuttle’s external tank fell off, causing a hole in the left wing and while returning to Earth the shuttle broke up in the air.

The explosion occurred due to a damaged left wing of the space shuttle which had a hole in it, caused by a piece of polyurethane Foam (avoids any type of ice freezing on the tank).

  • Polyurethane foam was applied to an external fuel tank which had liquid hydrogen and oxygen in it. A six-to-ten-inch-diameter piece of this foam fell off the external tank and created a hole in the shuttle’s left wing.

  • Unaware of the damage, the astronauts headed back to Earth atmosphere. The wing hole came into action and penetrated with the heat shield, ending up destroying the wing’s internal structure. This damage induced the shuttle to become unstable and explode.
