What was the Challenger mission?
Why did the Challenger explode?
A failure of the shuttle's right solid rocket booster (SRB) caused by record-low temperatures of the launch, and allowed hot pressurized gas from within the SRB to leak and burn the surrounding machinery. The failure of the internal system through the shuttle at incredible speed with aerodynamic forces that tore the ship apart.
