It has been 30 years since the Space Shuttle Challenger exploded off the coast of Cape Canaveral. All seven crew members, including teacher Christa McAuliffe, were killed.

This week on Florida Matters (Tuesday, April 5 at 6:30 p.m. and Sunday, April 10 at 7:30 a.m.), we'll remember the disaster, and take a look at some of the lessons learned from Challenger.

Many Americans watched in shock as the Space Shuttle Challenger disintegrated over the Florida sky 30 years ago.

U.S. Senator Bill Nelson, D-FL, was one of the viewers who had tuned in to the national broadcast. Then a U.S. representative, Nelson arrived back to earth only 10 days earlier after a six-day mission in space. 

It would be the final successful mission to space before the Challenger disaster.

On an upcoming Florida Matters, we're taking a look back 30 years ago, when the Space Shuttle Challenger exploded off the coast of Cape Canaveral, killing the seven crew members aboard.

Twenty-five years ago, an event occurred that is seared into the memory of most Americans: About a minute after liftoff, the space shuttle Challenger blew apart, killing all aboard, including teacher-astronaut Christa McAuliffe.

The day started off innocently enough. It was unusually cold in Florida that day, but NASA managers decided to attempt a launch anyway. As a subsequent investigation made clear, the cold temperature made O-rings, which were intended to contain hot gases, fail on the solid rocket boosters.
