Soaring through space at 25,000 per hour, Apollo 13 was on course for the Moon. Suddenly, the three astronauts aboard the spacecraft heard a loud bang. A strong vibration rumbled through the crew cabin. There had been an explosion in the oxygen tank. More than 200,000 miles from Earth, Apollo 13 was in grave danger. The astronauts had planned to land on the Moon, but now they had a new mission: survival. Author Henry M. Holden delivers the gripping details of how three astronauts, with the help of NASA scientists on Earth, turned a story of disaster into one of triumph.
