Question

What caused the space shuttle to blow up? ​

Answer 1

Explanation: The disintegration of the vehicle began after a joint in its right solid rocket booster (SRB) failed at liftoff. The failure was caused by the failure of O-ring seals used in the joint that were not designed to handle the unusually cold conditions that existed at this launch.

Answer 2

The space shuttle broke apart because gasses in the external fuel tank mixed, exploded and tore the space shuttle apart.
