Outer space Mission

Apollo 11

The first step into Forever

July 1969, Neil Armstrong's probably an ex-test pilot with a Boy Scout badge for spitting in the face of death, and on that day he find himself at Kennedy Space Center, wearing a spacesuit and about to board a strange machine. The machine is called "the Saturn 5 rocket", and is about three blue whales high, weighs about as much as thirty-five 737s, and very shortly, a million liters of liquid oxygen are going to mix with 700,000 liters of kerosene, and the machine is gonna go, and quite possibly KILL HIM DEAD! abd he hop in with your two other mates, strap up, and try to ignore the fact that you're about to ride the explosive equivalent of 400 tons of TNT up into the sky on the back of seven and a half million pounds of thrust. And sure enough, a system of valves open below him, mixing the liquid oxygen and kerosene, and are ignited. The cabin rocks left to right with the guidance computer gimballing the five gigantic F-1 engines 300 feet below him, desperately trying to stop you smashing into the launch tower. He is squashed back into his seat four times your normal weight. By 9:35 AM you're 42 miles high, riding 5% for America's federal budget into the morning sky. 

By 9:44 AM, the first two stages of the rocket are jettisoned, and you're 118 miles high. By 12:22 PM you're in orbit, going at 24,000 miles an hour – or, if you prefer, speeding around the Earth at about 17 times faster than a bullet. By 12:49, you get the word he'll go for trans-lunar injection. A few minutes of engine burn later, and he's now headed out of Earth orbit. He blow the bolts connecting the two sections of your rocket ship, separating his module from the lunar module, spin them around and dock again. The Earth begins to recede behind him. By 2:45 PM, he is now riding 26 tons of food, instruments, and science at about 25,000 miles an hour. He is the commander of Apollo 11. And while two NASA missions have orbited the Moon already, his will now attempt to be the first to land and stand on that alien world. Fun fact: peeing in zero gravity is a nightmare. To counteract this, since all Apollo astronauts were men, engineers developed a system whereby one would urinate into a condom attached to a hose. The condom sizes came in "small", "medium", and "large". Legend has it that some astronauts were choosing the large size based on pride, and some were making a mess because it wasn't the right size. Allegedly, NASA opted to rename the sizes "extra-large", "immense", and "unbelievable".Space exploration!

 Anyway, what is this big white thing you're flying towards? Where did it come from? Well, no one knows for sure yet. The leading theory is that about four billion years ago something about the size of Mars – a planet we've called Theia – hit the Earth, and bits of the Earth came off, and eventually collected together into old Moonface McGee itself. Which is about 81 times lighter than the Earth, about ⅓ the diameter – bigger than Pluto, by the way, but most things are – and its gravity is around ⅙ ours. It takes the Moon 27 days to orbit us properly, but it also takes the Moon 27 days to turn once on its axis, which means we only ever see one side of the Moon. The reason the moon looks different to us through the month is its position relative to the Sun. As she swings around us, she's either between us and the Sun, called "new moon", waxes into the first quarter, then full, wanes into third quarter, and back to new. And moons in our solar system aren't unique at all: Mars has 2, Neptune has 14, Saturn has 82, but we are the only planet in our solar system with one moon, weirdly, and it is by far the largest, relative to its planet. No good explanation for any of that yet, but boy, are we glad its here! It kindly regulates the tides and stops us wobbling on our axis. All in all, very pretty, very mysterious.

 And would you look at that – he is almost there. Well, about 33,000 miles away, but you've entered the Moon's sphere of influence. That means the Moon has more gravitational power over you than the Earth does. He is  in its house now. Out the window and below is a barren expanse, a visual history of great violence: craters where comets hit, some as wide as 175 kilometers in diameter. one astronaut stays in the command module, while he and his colleague transfer to the lunar module. And before he know it, he's separated and descending to the surface.

 Ancient and dead volcanoes have covered the Moon in 23 of what our ancestors mistook for "maria" – Latin for "seas", as we still call them today. the Sea of Crises, the Eastern Sea, and there, our destination – the Sea of Tranquility. But he's traveling too fast for some reason, and overshooting the landing spot. Still, he'd come all this way, and you'll be damned if you quit here. 6,000 feet above now, alarms go off: 1201 and 1202. No one back on Earth is sure what that even means, but they advise him to carry on with the descent. Beside him, his co-pilot calls out the altitude. He's now coming down on the southwestern edge of the Sea of Tranquility, but there are boulders the size of trucks everywhere – no sign of flat. He can't land here. He take over manual control, desperately looking for a smooth area to set down, the biometric sensors reading your heart rate at 156 beats per minute.and  fuel is dribbling away. 

If he can't find a safe spot, he have to abort the entire mission. 150 feet, 75 dropping still, then a dust cloud kicks up beneath him – five feet, two, one and a half, one, and his co-pilot calls contact light, and with a jolt and only 15 seconds of fuel left... You're down. And he said... "Tranquility Base here, The Eagle has landed." The schedule calls for the two of them to sleep, but you're the first humans to visit the Moon, for God's sake. During this time, his co-pilot takes Holy Communion, though does it on the quiet: NASA is currently engaged in a lawsuit with an atheist who had objections to a previous mission orbiting the Moon, and reading from the Bible as it did so. Then, at 2:39 AM, you open the hatch and slowly descend the ladder. He pull a lever, activating the camera already on the outside of the lunar module to witness what is about to come next. 

He reach the bottom of the ladder, still standing on the leg now. He observe the surface of the Moon is granular, almost like powder. He uncover a plaque on the lunar module, saying: "Here men from the planet Earth first set foot upon the Moon. July 1969, A.D. We came in peace for all mankind." Tentatively, he step back with his left foot onto the first celestial body humankind has ever visited. And having been allowed to choose those first words on a new world, you say: "That's one small step for  a man, one giant leap for mankind." Which will later be misquoted repeatedly without the indefinite article, as "One small step for man", Which makes no sense, if you think about it, because that would mean "one small step for Humanity, one giant leap for Humanity", but whatever – he's on the Moon. His colleague exits the lunar module, pausing on the ladder a few moments to become the first human ever to urinate while outside on the Moon, then joins him on the surface. 

He erect a United States flag and accept a call directly from your then-president Richard Nixon. The two of you experiment with transport methods, including kangaroo hops, he set up scientific equipment, he take photos, collect ground samples... But this picnic runs on oxygen. So, two and a half hours later after setting foot down here, the two of you climb the ladder again, and return to the lunar module, and attempt to sleep. You sleep – not very well, but... a little. It's time now to go home. They're both relying on a single ascent engine that can only be fired once, meaning one chance to leave. His colleague has somehow damaged the circuit breaker for the engine in the course of moving about. He jam a felt-tip pen in there, hoping that to your third colleague will be flying overhead shortly, waiting to rendezvous if all goes well. The ascent engine is fired, everything goes fine.
