Eight years after President John Kennedy declared his ambition to send people to the Moon, this desire finally materialized through Apollo 11.
But the bitter pill had to be swallowed up by the American population after Kennedy's tragic murder in 1963 and had no time to make his dream come true. Under the leadership of Richard Nixon, the US continues to strive to become the number one country in space. The US desperately avenged the defeat of the Soviet Union, which managed to send the first man into space, Yuri Gagarin.
After the mission of Apollo 11 was over, the superpower still survived human programs to transmit other moons, including Apollo 12, Apollo 14, Apollo 15, Apollo 16 and Apollo 17. Five of them successfully delivered the people on the moon. Everything examines the land of the moon.
But Apollo's mission can only survive to number 17. It then appears that NASA chooses a break from the long journey of the greatest achievement of mankind.
Since then, the astronaut has not returned to Earth, although many vehicles and robots are sent to the moon to explore or simply explore, hoping to find something new. But these machines are unmanned.
Indeed, NASA has built several pilot projects since Apollo ended, including the Constellation program, in the mid-2000s. Unfortunately, none of these programs is able to get the farthest distance into space.
So why did NASA quickly re-process Apollo's mission in the past, but now she does not? What does Apollo now distinguish from the mission?
While NASA's focus has also changed. This US government space agency seems to be changing its "goal": sending people to Mars.
Yes, NASA plans to send its best astronaut to Mars in the near future. According to official information on their site, NASA wants to bring people to the Red Planet in 2033.
Although there has never been a single person who can climb Mars, a number of explorers have managed to land there to explore the soil and other elements that could support living beings.
Although it is interesting to think about people who can live on Mars, the reality is that they will face many problems during their research.
From long-lasting dust storms, very high levels of solar radiation, food shortages and overall health support.
Can we send people to Mars in the next 10 years?
Astronauts have to travel very far to arrive on Mars. Before the flight takes place, they need to examine in detail the location of the planets in the solar system as the distance between the planets always changes as they travel around the sun.
While the average distance between Mars and the Earth is 140 million miles, the distance between them is closer to each other, depending on their position around the sun. Earth and Mars are in the closest position to each other when Mars is in the closest position to the sun – and the Earth is in the furthest position from the Sun.
At that time, the two planets would be 33.9 million miles apart. When the planets are located on the opposite side of the Sun, they are at a distance of 250 million miles from each other.
According to NASA, the ideal launch of Mars will take about nine months. Similarly travel time is returned to Earth. This is not added to the length of time they lived on Mars.
"This is pessimistic over the next ten years, which means that … The moon is only 384,400 kilometers, and Mars can vary, it can reach 210 million kilometers or more, depending on the orbital period at that time. for three days, while on Mars at least six months, a maximum of two years, "astrologer observer Marufin Sudibu explained Liputan6.com on Tuesday (23.7.2015).
Astronauts have to face many obstacles to go to Mars. It's hard, it's not easy and astronauts have to understand that. People who walk on the moon will experience conditions without gravity, but this happens only three days and is relatively easy to overcome.
While someone is on Mars, he will experience conditions without gravity for six consecutive days, that's the minimum, so he can significantly affect his body.
"The mass of our bodies is largely controlled by Earth's gravity, such as blood circulation, bone density, and the digestive system, and when there is no gravity, all this will be disturbed." There is one study that says astronauts are in space , he loses 1% bone mass per month, "Maine Rufin explained.
Besides being limited by gravity, there is another obstacle that scientists have to overcome, namely to find ways to deliver astronaut food. If the two vital things are overcome, according to Marufin, perhaps people can land safely on Mars.
"It means landing like a normal person, exploring Mars as a normal person, and then returning to Earth as a normal person. But if we do not pay attention to the important moments, just stay flying and think whatever happens will depend on you. " this is impossible, "said Marufin, an astronomer at the National Agency for Intelligence and Religious Affairs.
