The landing of 12 people on the moon is one of NASA's greatest successes, if not
Not the biggest at all. Astronauts gathered rock, took pictures, experimented,
They planted flags and then returned home, but this stay of a week
During the Apollo program has not established a permanent human existence on the moon.
More than 45 years after the last landing by "Apollo" 17
December 1972 on the moon, there are many reasons to bring people back to
The Earth
Researchers and contractors found that a base on the moon could turn into a fuel depot
For deeper spaceflights, and lead to the creation of unprecedented space telescopes, and facilitate
Live on Mars, through which we can solve the scientific mysteries on Earth and the creation of the moon,
Al Qaeda can become a thriving economy outside the world and perhaps a tourist building
Lunar space
Former Astronaut, Business Insider Chris Hardfield: "The logical step
The following is the establishment of a permanent human research station on the moon, the moon away from us three
Only a few days, we can bear the mistakes without killing everyone, and we have a variety of things
What we invented and then tested before going further into the space world. "
However
Many astronauts and other experts point out that there are more obstacles
Lunar missions over the past four decades, a bit frustrating.
The obstacle facing any space program, especially that of a scholarship
People, is a cost hurdle, where President Donald Trump signed in March 2017
NASA's budget, which stands at about 19.5 billion US dollars, could reach 19.9 billion
US $ in 2019.
But this budget is not enough to cover all sections of the agency and projects
Ambitious, including the James Webb Space Telescope and the Missile Project
Giant, called the space launch system, and remote missions
Sun, Jupiter, Mars, etc.
According to a report by NASA in 2005, the return to the moon will cost
About $ 104 billion (equivalent to $ 138 billion today, with inflation) over 13 years
Almost a year.
The Apollo program costs about $ 120 billion in current dollars.
Cunningham during his testimony, "Human exploration is the most expensive space project, so
Is the most difficult to obtain political support, unless Congress decides to put more
The money that is there is just talking. "
Referring to the Mars missions and returning to the moon, Cunningham added," NASA's budget
Too low to do all the things we talked about here, "seems to be the bosses
Congress does not care to stay on track, in 2004, for example, at the time of
The Bush administration, NASA spent $ 9 billion on the Constellation program.
Design, build and test devices for the manned space flight program, after
As President Barack Obama took office, the Government Accountability Office released a report on disability
NASA has estimated the cost of the Constellation program, urging Obama to cancel the program, and signed a rocket launch system
(SLS) Instead, Trump's management did not override the SLS program, but it did not target.
Thus, these frequent changes to NASA's costly priorities,
After the cancellation, to the loss of nearly $ 20 billion, and years of wasted time and momentum.
Jim Lovell, an Apollo 8 astronaut, told Business Insider in 2017: "I was disappointed because they were too slow. Enthusiastic for everything
Something in the near future. "
The real driving force of the government's commitment to return to the moon is
The will of the American people, who vote for politicians, helps shape political priorities, but the interest
The general lunar exploration was always lukewarm.
Up
At the top of the Apollo program, only 53% of Americans thought the program was worth the cost,
Today, 55% of Americans believe that NASA should make the return to the moon a priority, although
Only a quarter of those who believe it should be a top priority, according to a poll
Released in June, but 44% of those surveyed believe that sending
Astronauts at the moon should not be done at all.
NASA's budget is not the only reason people do not come back on the moon, the moon is also
A deadly trap for humans, aged 4.5 billion years, and should not be underestimated or underestimated
Its surface is full of craters and rocks that threaten a safe landing, but the biggest concern is knowing what
Created by the effects of meteorites, which is called moon dust.
Madhu Thangafilo wrote in 2014: "The moon is covered with a top layer of
Moon dust is talc, which is electrically charged by interaction with the wind
Solar and other factors, and mess up the spaceship very quickly. "
There is also a problem with the sunlight, they are for 14.75 days or
A fiery field of fire exposed to sunlight, and the next 14.75 days will be in
Which makes the moon's surface one of the coldest places in the universe.
There is no doubt that astronauts will return to the moon and then on Mars, it's just a question
Time
says
Lovell: "I think that in the end things will come back, they will return to the moon, and they will go to the end
It's going on Mars, maybe not in my life, but I hope they'll succeed. "
