On July 20, 1969 men from the Earth stood for the first time on the surface of the Moon. The successful landing of Apollo 11 on the

surface of the Moon signalled the beginning of the study of the Moon's rocks and minerals, the new science of lunar geology.

About 150 scientists from laboratories throughout the world con- ducted a wide range of geological, chemical, physical and biological tests on the rocks returned to Earth. These scientific studies have led to new discoveries about the Moon. Most dramatic of all was that the Moon was born at the same time as the Earth, about 4600 million years ago.

It should be noted that the early astronomers, starting with Galileo who in 1610 first used a telescope, observed lunar surface.

The first astronauts to land on the Moon, Armstrong and Aldrin collected 22 kg (481 Ib) of rocks. Since then, another 5 Apollo lunar missions have taken place. Apollo 17 landed on the Moon on December 11, 1972. The total rock collected amounts to 382 kg (845 Ib) plus 0.13 kg (4.6 oz) from the two unmanned Russian Luna missions. At the Lunar Receiving Laboratories in Houston, the USA, are catalogued 35,600 small pieces of the Moon.

Our satellite is about '/₄ of the Earth's size and'/, of its mass. Hence its gravity is only '/₆ of Earth's.

The temperature changes between lunar day and night. Temperature ranges from 110° С (230° F) at the height of the lunar day to -170° С (-275° F) in the lunar night.
