Hello, Mrs. Möller and Mrs. Voss

Apollo 11 was the eleventh mission that was successfully sent to the moon. The Apollo 11 space flight was sent to the moon with the Saturn V rocket. The mission was carried out by the United States of America. With this mission the world has seen the victory for the U.S.A. in the cold war Space Race against Soviet Union. This Mission was launched from Florida on July 16th 1969 that was the mission of NASA. In this mission were Commander Neil Alden Armstrong, Command Module Pilot Michael Collins and Lunar Module Pilot Edwin Eugene. On July 20th, they landed on the Moon and on July 21st the first humans to walked on the moon. The three astronauts returned to Earth and landed in the Pacific Ocean on July 24. Apollo 11 fulfilled President John F. Kennedy’s goal to reach the moon.


Start and landing


On 16 July 1969 began one of the greatest adventures of humankind: the landing of humans on the moon. About 1 million spectators have gathered in Brevard Country, at the launch of Apollo 11 with astronauts Niel Armstrong, Michael Collins and Edwin Aldrin directly witness. Right on time at 9.32 U.S. Eastern Time Clock lifted the Saturn V from the ramp 39 A. After the first and second stages were burned, the rocket worked the 3rd Level two and a half long minutes, until they reach the onboard computer to shut down by the orbit. In the next 2 hours and 20 minutes, the on-board systems checks and the preparations for the second firing of the third stage. By this firing, the spacecraft was nudged out of orbit.

The spacecraft entered lunar orbit at 1:28 p.m. EDT on July 19. During the second lunar orbit a live colour telecast of the lunar surface was made. A second service-propulsion-system burn placed the spacecraft in an orbit, after which astronaut Aldrin entered the LM (Lunar Module) for two hours of housekeeping. After they had entered the moon, Armstrong reported to the mission control center on the earth: "Houston, Tranquillity Base here - the Eagle has landed."

Man's first step on the moon was taken by Armstrong. As he stepped onto the surface of the moon, Armstrong described the feat as “one small step for a man - one giant leap for mankind.”



Bases of the rocket construction

The Saturn V rocket is one of the most powerful spacecraft built by mankind. With a height of 110 meters it weights almost 3,000 tons, 2,600 tons of which are highly explosive fuel. This miracle of technology, however, was designed and built for one purpose only - it should bring the 45-ton Apollo spacecraft with three American astronauts into orbit around the moon.


Due to the gravity of the earth, it is not easy to start a spacecraft into the space. If these other heavenly bodies are to reach, they must overcome the earth gravitation, because otherwise they would back-fall on earth. In addition spacecraft need a minimum speed. With a start of our planet, this is at least 11.2 kilometers per second, and in order a rocket on a so high speed to bring, are enormous quantities to fuel and gigantic engines are necessary.



Lunar Experiments


Directly after entering the moon Armstrong and Aldrin furnished the television cameras and set up the American flag. Afterwards they concerned the scientific work. In addition belonged above all collecting moon rock, which the astronauts would carry forward later to the earth.


They unrolled the so-called “Staniolstreifen”, which should catch particles of the sun. Such experiments are not possible on earth, since the atmosphere and the magnetic field let through hardly solar wind.


In addition the two Americans on the moon would install a laser beam reflector, with whose assistance one can measure the distance between earth and moon. To Armstrong’s and Aldrin’s tasks were also setting up the so-called “Seismometers”, which had to note moon quake. First it registered however only the vibrations caused by the astronauts. On 23 July the first moon quakes were based.
