On July 10 at Cape Kennedy discovered a flaw in the pressure system of the Apollo XI. Initial reports that had was that the
problem was related to pressure system oxygen-based liquid helium in the first stage of the Saturn V rocket However, this has not delayed the opening of the account
regressive began that day to twenty hours. The astronauts continued preparations for the great adventure. On Friday 11, the astronauts of Apollo XI were subjected to the last "great physical examination" before starting the flight. The scientist German space and Marshall Center Director of Aeronautics, Werner von Braun said: "We are confident that it will be a total success as the Apollo X (...) It is about to complete the course of the young heroes of the space (…) We will have space stations inhabited by all sorts of people, who will fly to orbit as passengers but the crew will consist of properly trained pilots. While launching the staff filled the nave command "Colombia" with helium and oxygen in addition to submitting to pressure the fuel tanks of the module "Eagle". Descending control the vehicle landing of Apollo 11 was a difficult task. Armstrong and Aldrin tested thousands of times the most critical phases of flight in the lunar module. Michael Collins, who descend on the moon
, An airplane flew T-38 jet that honed his experience for the trip. The countdown or count dawn "was held as scheduled. The recess was twelve hours. In total, the countdown lasted ninety-three hours Experienced astronauts rose at dawn and after rigorous medical check, breakfasted and were assisted to get into the complex space suits. They were then taken to the launch pad, where they entered the capsule. The clocks in Argentina at 10:32 am on Wednesday 16 July 1969. The countdown had ended and the great power of man to set foot on the surface of the moon, just beginning. The Saturn V rocket and its three crew, Neil Armstrong, Michael Collins and Edwin Aldrin, left Earth accompanied by a deafening sound and a giant red flame. The five engines of the spacecraft achieved an overall
speed of forty thousand miles an hour, momentum necessary to overcome the force of gravity. The Saturn V boosted the spacecraft to a hundred feet high, placing it in the planet's orbit, and then discarding the three-stage rocket to the extent that each exhausted their hydrogen fuel and liquid oxygen. The launch of the Saturn V was not of any problem. At Cape Kennedy, a former Cape Canaveral, the sea withdrew tourists (reportedly was more than a million cars that created one of the largest blocks of history) and the media were working frantically to tell his story. The present day climatic conditions characteristic of the area: hot, humid and slightly overcast. The spacecraft went into orbit at a height of one hundred and eighty-five kilometers of land area where the mother cosmonave reached a speed of twenty-eight hundred miles per hour. The spacecraft spent flying around the Earth until 13:16 hrs (Argentina). The Apollo XI was operated the third stage rocket. At that instant the speed increased to almost double what it was, to begin the journey of four thousand miles, about the moon. The aim was to leave Earth's gravity. With impeccable precision direct the astronauts went to the moon. When twenty-one hours had elapsed since they left the launch pad they had gone one hundred and seventy thousand miles. The rate was seven thousand one hundred kilometers per ora. One day after launch, with a crew much more relaxed and joking, the mission crossed the midpoint of the trip. The average speed was nearly five thousand miles per hour. The main engine of the Apollo XI went on for three seconds and placed in a more precise way to the moon. On July 19 Space Center in Houston announced that Apollo came into the gravitational pull of the moon, is even faster.
