BBC – Future – Apollo in 50 numbers: Time



15.28: A combined flight experience of the Apollo 14 crew, in minutes and seconds

On May 5, 1961, Allen Shepard became the first American in space. His 15-minute, 28-second sub-orbital flight was, according to Apollo 7 astronaut Walt Cunningham, "the most beautiful 15-minute walk ever known by any American."

In his "All-American Boys" autobiography, Canningham describes Shepard as "capable, stubborn and just good at whatever he has done."

Shepard is ready to become the first man on the moon. Then, a few months after his historic flight, the astronaut was diagnosed with a rare state of the inner ear and was grounded indefinitely.

But he's determined to get to the moon and in 1

969 is undergoing a risky operation to fix an ear problem. The operation was successful and by the summer of 1969, America's first and now oldest astronaut returned to flight status. Shepherd is also assigned to command Apollo 13 with astronauts Ed Mitchell and Stewart Roose.

He did not fly in space. Soon they became known as "recruits" and NASA made them go to Apollo 14 to give them more time to train. Finally, on February 5, 1971, Shepherd became the fifth man-and only Astronaut from Mercury-7 to walk on the Moon. The mission was the first to carry a Modular Equipment Conveyor (essentially a gifted cart) that allowed Shepherd and Mitchell to collect more lunar samples than previous missions.

Shepard also took the opportunity to become the first and only astronaut to play golf on the moon. Live on TV, he put six iron on a modified sampling handle and hit two balls "miles and miles".

38,000: Total time astronauts trained in simulators in hours

For astronauts everywhere in space, hundreds of training sessions have taken place. Each aspect of the mission was simulated as realistically as possible. Nassa has even built giant Moon models to show astronauts how the orbital surface and the simulated lunar landscape appear to be able to practice collecting soil and rock samples. the real thing, with the same keys, dials and displays. The simulators are linked to control consoles where trainers can work through missions and throw system failures on the crew to see how they deal with them. "It was funny," Flight Director Jerry Griffin said, "we're going to make a mistake, and we'll make it, give us another, then there will be two, and we'll fight a bit." "In the end, they can bring us to our knees," he says. "We'll be disappointed with them and say," It's unrealistic, "but they'll just smile – they've never tried to escape, but they had a way out if someone really lost it.

A simulator almost cost the first man on the moon, Neil Armstrong, his life

Despite the tension, initiation of training and simulation manifested itself again and again during Apollo missions – from the proper interpretation of alarms during the landing of Apollo 11 to the drama of the Apollo 12 launch or explosion during Apollo 13.

However, a simulator who almost cost the first man on the moon, Neil Armstrong, was his LLRV, known as "flying bed Armstrong was on his 22nd LLRV flight at Houston Airport when the machine suddenly got out of control, and the astronaut took off, landed on the parachute to the Earth, and left undamaged

80.32: Total Time Outside the Moon Surface in Hours and Minutes

About 25 billion dollars and 400,000 people allowed 12 men to travel 385,168 miles to land on the moon. But once outside their spaceship, the astronauts had enough oxygen and water for a few hours to work on the moon's surface.

Thanks to the precise planning of missions, checklists and routes, astronauts have received much science, they have gathered stones and soil and explored experiments for particle exploration, gravity and magnetism

During Apollo 11, Neil Armstrong and Buz Aldrin spent two hours and 31 minutes outside the cabin. Later missions allow two excursions, and in the final missions three. During Apollo 17, astronauts Jin Chernan and Harrison Schmidt spent a total of 22 hours exploring the moon's surface.

As the first scientist to walk on the Moon, Schmidt put into practice the training he had provided to the other Apollo teams.

"Wait a minute," he says to Cherban during their second excursion, "There is an orange soil!"

"Everything is done – orange!" He adds excitedly as they walk closer. for the lunar travelers of Apollo we know that the moon is ancient, lifeless and formed from the same general material as the Earth

"Is the same color as cheese?", calms Captain Robert Parker in mission control.

The orange soil is one of the most significant scientific discoveries of Apollo's missions. Later the analysis proved that these were melted drops of lava thrown away by an ancient volcano.

Thanks to Apollo's lunar travelers, we know that the Moon is ancient, lifeless and is formed by the same general Earth-like material, probably through a giant cosmic collision. We know about the moon waves, the weak moon atmosphere and the exact distance to the Earth.

If all the lunar science can be achieved in 80 hours, imagine what a permanent human presence on the Moon can achieve.

73: The Time of Astronaut "Apollo 15" Al Wardon, spent alone in space, in hours

"While Neither Armstrong, Buzz Aldrin and … they played with the moon, the third member of the Apollo crews could easily be forgotten. The command module pilot was the second one to command the mission, and he had to run the spacecraft alone if his satellites were stranded on the moon's surface.

During Apollo 11, Mike Collins traveled around the Moon, while Aldrin and Armstrong were making history on the surface. As a pilot of a command module for Apollo 15, Al Worden spent 73 hours alone in orbit around the moon in July 1971, after waving Dave Scott and Jim Irwin.

"I was alone, but I was not lonely," he says. "I did not have to talk to Dave and Jim anymore unless they came [when the orbiting command module was above the landing site] and said hello.

"On the back of the moon I did not even have to speak in Houston and that was the best part of the flight," he says.

Warden's work was to study the moon from orbit with cameras and sensors, but he must also look the opposite in space. there are billions of stars – the Milky Way galaxy in which we are located, contains billions of stars, not just a few – Al Worden

"I found the number of stars so huge. I could not take separate stars, it was like a sheet of light, "he says. "There are billions of stars there – the Milky Way galaxy we are in, contains billions of stars, not just a few. And there are billions of galaxies. "So what does the universe say to you? This tells us that we just do not think big enough. "

47: Time Since People Last Walked On December 14, 1972, the commander of Apollo 17 Gene Chernan came out of the moon's surface and climbed the stairs of the moon trigger. His last words were as moving and meaningful as the first words spoken by Armstrong.

"We are leaving when we come, and if God agrees, as we will come back," said Chernan, "with peace and hope for all mankind.

A few days later, the command module of Apollo 17 spilled into the Pacific Ocean. And that was it. Apollo Luna's story was over

When I interviewed Chenan in 2014, and again two years later, he was still angry that mankind did not come back to finish what America began. The astronaut died in 2017, so he never saw the starter pads at Kennedy Space Center in Florida, repaired for the giant new SpaceX missile and NASA SLS.

Probably several Apollo astronauts will still see the first. Woman Walking On The Moon

SLS is the first starter since Saturn V is able to bring people back to the moon. And 50 years after Neil Armstrong and Buzz Aldrin took their first small steps, we could finally see the next giant leap.

NASA has promised to bring people back to the Moon by 2024 and work with other international space agencies. Later, a lunar base was created. This is narrow, but (Nasa said) we are reaching a deadline and this time promise that one of the astronauts will be a woman. Walk on the moon.

But it's also possible that the next man on the moon is not an American. There is a chance for the Chinese to reach them [196590053] –
