After separation from the carrier aircraft the pilots completed a controlled descent and precise landing at Edwards Air Force Base, confirming earlier aerodynamic predictions and providing engineers with valuable information for the construction and operation of the orbital shuttle fleet.

The astronauts visited geological features near the Apollo 15 landing site in the Hadley-Apennine region, collected samples, and deployed scientific experiments, while television images transmitted from the rover allowed audiences on Earth to observe the exploration.

At 11.39am Challenger lifted off, and seventy-three seconds later the Shuttle began to disintegrate following a huge fireball. All seven members of crew were killed, and the disaster led to NASA suspending all Space Shuttle missions for over two and a half years.
