The landing of 12 people on the moon is one of NASA's greatest successes, if not the greatest. The astronauts gathered rocks, took pictures, experimented, planted flags, and then returned home, but this week-long stay during the Apollo program did not establish a permanent human presence on the moon. .
More than 45 years after the last landing "Apollo" December 17, 1972 On the moon, there are many reasons to bring people back to earth.
Researchers and businessmen believe that a base on the moon could become a fuel depot for a deeper space flight. Create Unprecedented Space Telescopes and Make Life Easier on Mars [1969003] Former Astronaut, Business Insider Chris Hardfield, said: "The next logical step is to establish a permanent human research station on the Earth , The moon, the moon is only three days away, we can stand the errors without killing everyone, and we invented a set of things that we tested before going any further in the space world. "
What are the biggest obstacles to lunar missions around the world?
The hurdle facing any space program, especially that of people, is the cost barrier: President Donald Trump signed in March 2017 a NASA budget of about 19.5 billion US dollars 19.9 billion in 2019.
But this budget does not not enough to cover all the ambitious projects of the agency, including the telescope James Webb Space, the project of launching giant rockets, the space launch system, Distant to the Sun, Jupiter, Mars, etc.
According to a report from the NAS agency In 2005, the return to the moon would cost about $ 104 billion (about $ 138 billion today, with inflation) for nearly 13 years.
The Apollo program costs about $ 120 billion in current dollars.
Cunningham During his testimony, "human exploration is the most expensive space project, and therefore the most difficult to obtain political support, and unless Congress decides to invest in it more money. "
"NASA's budget is too low to do all the things we've talked about here," and Presidents and Congress seem to be out In 2004, for example, under the Bush administration, NASA has spent $ 9 billion in the Constellation program
after designing, building and testing the equipment for the manned space flight program, and after the inauguration of President Barack Obama, the Government Accountability Office reported the NASA's inability to estimate the cost of the Constellation program, prompting Obama to cancel the program, and signed the SLS rocket instead. Trump's leadership did not override the SLS program, but n & # 39; 39 not covered
. ] Therefore, these frequent changes to NASA's costly priorities, cancellation after cancellation, Jim Lovell, an Apollo 8 astronaut, told Business Insider in 2017: "I've been disappointed because they were too slow. "" I'm not excited about anything. The real driving force behind the government's commitment to return to the moon is the will of the American people, who vote for politicians and helps shape political priorities, but the public interest in lunar exploration has always been lukewarm
. Only 53% of Americans thought the program was worth the cost, and today 55% of Americans think that NASA should According to the June poll, the return to the moon is a priority, even if only a quarter of 39 believe that this should be a top priority, but 44% believe that astronauts should not be sent to the moon. 19659003] But NASA's budget is not the only reason people do not return to the moon, the moon is also a deadly trap for humans, 4.5 billion years old and not should not be underestimated. Sure, but the biggest concern is created by the effects of meteorites, what is called moon dust.
Mado W. wrote "The moon is covered with an upper layer of lunar dust in the form of talc, which is electrically charged by interfering with the solar wind and other factors, and spoils the vessel space very quickly. "
There is also a problem of 14.75 A day is a fiery field exposed to sunlight and the next 14.75 days are in total darkness, making the surface of the moon l & # 39; 39, one of the coldest places in the universe.
Astronauts are likely to return to the moon. Time
Lovell said, "I think at the end things will come back, and go back to the moon, and go to the end of the millennium
