Watching TV, Satsuki learned that more than 40 years have passed since human beings landed on the moon. She was surprised that humana had gone into outer space so long ago. （２）（She did an Internet search so as to learn more about it）, and read some articles on the moon landings.
On July 20 1969, the first moon landing was achieved by U.S. astronauts Neil Aemstrong and Buzz Aldrin. The U.S. in the 60's was putting all its energies into the Apollo Program, a human moon-landing project, and the astronauts reached the moon aboard Apollo 11. Following this, five other Apollo spacecraft landed on the moon by 1972.
Among the articles about human efforts to land on the moon, Satsuki found one referring to the Apollo 13 accident. Apollo 13 was launched on April 11 1970, and on the way to the moon, one of its oxygen tanks exploded. There was not enough oxygen left to do research on the moon. For fear that they would run out of oxygen, the crew decided to abandon the landing. The space ship circled around the moon and then returned safely to Earth. If the crew had not judged the situation calmly, tha result would have been a terrible accident.
Satsuki was deeply moved by this story. From it she learned that even if something had happens we should stay calm and have the courage to give up something important instead of being reckless.
