SPACE CONQUEST

In a speech to the Congress in 1961, the US President Kennedy challenged the nation to put a man in the moon before the end of the decade. After the president’s speech, NASA’s Apollo program was developed to meet the challenge.

On July 16, 1969, the Apollo 11 was launched. The astronauts on board of the spacecraft were Neil Armstrong, Buzz Aldrin and Michael Collins.

On July 20, 1969, Neil Armstrong became the first man on the moon. He was followed by Aldrin 40 minutes later. TO walk on the moon surface, the astronauts need to wear a spacesuit with a portable life support system. This controlled the oxygen, temperature and pressure inside the spacesuit.

Armstrong and Aldrin spent a total of two and a half hours on the moon’s surface. They performed a variety of experiments and collected soil and rock samples to return to the Earth. An American flag was left on the moon’s surface as a reminder of the achievement.

The crew of Apollo 11 returned to the Earth on July 24, 1969. They successfully completed their historic mission. It is regarded as the greatest human efforts in the history of man kind.
