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.
