Armstrong and Buzz Aldrin spent 2 ½ hours on the lunar surface, but Armstrong was the first one to set his foot on the Moon’s surface. -
The Apollo 13 Accident
The Apollo 13 malfunction was caused by an explosion and rupture of oxygen tank no. 2 in the service module. The explosion ruptured a line or damaged a valve in the no. 1 oxygen tank, causing it to lose oxygen rapidly. The service module bay no.4 cover was blown off. All oxygen stores were lost within about 3 hours, along with loss of water, electrical power, and use of the propulsion system.In order to save the lives of the men the original mission had to be aborted . -
