The Earth's nearest neighbour, the Moon, was the most studied object in the night sky long before the first rocket was launched - a talisman for lovers, an emblem for dreamers, and a familiar friend to astronomers. To the Moon The United States got its first taste of moon dust in 1964 when its unmanned spacecraft crashed onto the lunar surface. On January 27, 1967, astronauts Virgil Grissom, Edward White and Roger Chafee entered the first Apollo capsule for a pre-flight test. All three were killed when a fire swept through the Apollo command module. The missions designated Apollo 4, 5, 6,7, 8, 9 and 10 were unmanned test flights flown in Earth orbit to test the techniques and technology that would go to the Moon. On July 20, 1969, Apollo 11 reached the Moon with two astronauts on board. Neil Armstrong took the first steps on the Moon proclaiming: "One small step for a man, one giant leap for mankind." Apollo 12, 14, 15, 16, 17 landed on the Moon between 1969 and 1972 with astronauts on board. The Apollo 13 landing was cut short because the service module suffered an explosion. The mission was designated a failure, having succeeded in only one of its objectives the safe return of the astronauts. When the Apollo 17 crew left the lunar surface, they knew that they were the last people to walk on the Moon - a cash-strapped U.S. government planned no more Apollo missions. More than a quarter of century later they are still the last. After Apollo, scientists reported stunning details about the Moon. It is 4.5 billion years old; about the same age as the Earth. It is made of ancient rocky stuff that has been melted, erupted and crushed by meteorites. The average surface temperature on the Moon is -10°F (-23,3°C). The percent of the Earth's gravity on the Moon is 16%. Flight time to the Moon is 4 days. There is no water on the Moon, no magnetic field, no atmosphere - the 3 indispensable conditions for the existence of life. But recently, water has been found on the reverse side of the Moon.rezumat la text va rog mult dau coroană. va roooooggg !!!!
