       Apollo 11 and the Moon landings

      “The ‘a’ was intended. I thought I said it. I can’t hear it when I listen on the radio reception here on Earth, so I’ll be happy if you just put it in parenthesis.

       Neil Armstrong commenting on his own quote and the most famous space line ever spoken: ‘That’s one small step for [a] man, one giant leap for mankind’.

       WHEN

      July 1969

       ENDEAVOUR

      Putting a man on the Moon

       HARDSHIPS & DANGERS

      The crew risked death by accident, fire, solar radiation and even drowning on their return to Earth.

       LEGACY

      The crew achieved perhaps the single greatest ‘first’ in human history. The Apollo program transformed the fields of astronomy, aerospace and computing, and put space at the forefront of our collective imagination.

      The first step on the moon by a man was also the last of an eight-year odyssey by the largest expedition team in human history. On 20 July 1969, Neil Armstrong had travelled 384,000 km (240,000 miles) in four days – the equivalent of nine circumnavigations of the Earth – through the deadly vacuum of space. But the Apollo program that put him there had employed the skills of 400,000 people for nearly a decade. More than 20,000 companies and universities had supplied equipment and brainpower. The project cost $24 billion and was easily the largest and most technologically creative endeavour ever made in peacetime. It was nothing less than the longest, most dangerous and most audaciously conceived expedition the world had ever seen. The catalyst was the singular vision of one man.

      Race into space

      On 12 April 1961, the Russian cosmonaut Yuri Gagarin became the first man in space. Just eight days later, US President John F. Kennedy (who had only been in office for three months) wrote this in a memo to his Space Council:

      ‘Do we have a chance of beating the Soviets by putting a laboratory in space, or by a trip around the moon, or by a rocket to go to the moon and back with a man. Is there any other space program which promises dramatic results in which we could win?... Are we working 24 hours a day on existing programs? If not, why not?’

      His choice of words – ‘beating’ and ‘win’ – made it very clear that he was intent on winning the Space Race.

      Apollo takes to the skies

      At this point, the United States was lagging behind the Soviet Union. One American astronaut, Alan Shepard, had flown into space, but he had not achieved orbit. The first Russian Sputnik craft had orbited the Earth in 1957.

      NASA was given the funds to launch a completely new space program – Apollo – dedicated to achieving Kennedy’s stated goal ‘before this decade is out, of landing a man on the Moon and returning him safely to the Earth’. A new Manned Spacecraft Center (nicknamed ‘Space City’) for human space-flight training, research, and flight control was built in Houston, Texas. A vast launch complex (now known as The Kennedy Space Center) was built near Cape Canaveral in Florida.

      Hundreds of the planet’s greatest scientific brains would spend the coming years solving seemingly impossible problems at breakneck speed, to create a rocket and spacecraft that could get a crew into orbit, then onwards to the Moon, down to its surface, and then repeat all these steps in reverse.

      The program suffered a serious early setback. The Command Module of Apollo 1 caught fire on 27 January 1967, during a prelaunch test, killing astronauts Virgil Grissom, Edward White, and Roger Chaffee. But NASA learned from the disaster and went back to the drawing board to make their craft safer. In December 1968, the second manned Apollo mission, Apollo 8, was successfully launched. It became the first manned spacecraft to leave Earth orbit, reach the Moon, orbit it and return safely to Earth. After two more successful launches, Apollo 11 was cleared for launch on 16 July 1969.

      Sitting in their tin can

      On 16 July, 1969, Neil Armstrong, Edwin ‘Buzz’ Aldrin and Michael Collins strapped themselves into Columbia, the command module of Apollo 11. This tiny conical cabin would carry the three astronauts from launch to lunar orbit and back to an ocean splashdown eight days later. Connected to the bottom of the command module was the cylindrical service module, which would provide propulsion, electrical power and storage during the mission. Below that was Eagle, the lunar module that would make the actual descent to the Moon’s surface.

      Their tiny habitat was bolted on to the top of a colossal Saturn V rocket. At 111 m (363 ft) high, Saturn V stood 18 m (58 ft) taller than the Statue of Liberty. It is still the tallest, heaviest, and most powerful rocket ever built.

      ‘But why, some say, the Moon? Why choose this as our goal? And they may well ask, why climb the highest mountain? Why, 35 years ago, fly the Atlantic?

      .........

       We choose to go to the Moon. We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills; because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win…’

       President John F. Kennedy

      The journey between worlds

      The gargantuan engines roared for eleven minutes, burning 2 million kg (5 million lb) of liquid oxygen and kerosene at over 13 metric tonnes per second to hoist the three astronauts into the heavens.

      Two and a half hours after topping 40,000 km/h (25,000 mph) and reaching orbit, another rocket burn set them on course for the Moon. The astronauts spent the next three days coasting through the void. On the fourth day they passed out of sight behind the Moon and fired rockets to ease them into orbit 100 km (62 miles) above the dusty surface.

      Armstrong and Aldrin climbed into the Eagle and said farewell to Collins. He would remain alone in Columbia in orbit while his colleagues walked on the surface. The landing craft separated and for twelve minutes a computer guided Armstrong and Aldrin down. Fear flashed through СКАЧАТЬ
