What is the Columbia spaceship?

There have been several spacecraft named "Columbia". The Space Shuttle orbiter Columbia was destroyed on reentry. Columbia's debris was collected by NASA for reconstruction to determine the cause of the accident. That debris is now stored on an upper floor of the massive Vehicle Assembly Building at the Kennedy Space Center to allow for additional study at a later date if necessary.

The capsule that returned the Apollo 11 astronauts to Earth was also named Columbia. It is on display near the entrance of the National Air and Space Museum in Washington DC.
