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 "The next logical step is to set up a permanent human research station on the moon," said Chris Hedfield, a former Business Intelligence astronaut. "The moon is three days away from us, we can handle mistakes without killing everyone, and we have a set of things we need to invent, then test them before we go deeper into the space world."
There have been more obstacles to lunar missions over the decades
The hurdle that any space program faces, especially that of sending people, is the most important. Cost barrier: In March 2017, President Donald Trump signed NASA's budget of about $ 19.5 billion, and could reach $ 19.9 billion in 2019.
But this budget not enough to cover all of the Agency's ambitious projects, including the James Webb Space Telescope, the Giant Rocket Project, the Space Launch System, Au soleil, Jupiter, Mars, etc.
According to a report released by NASA 2005, the return to the moon will cost about $ 104 billion (about $ 138 billion today, along with inflation) for nearly 13 years.
Apollo program costs about $ 120 billion in current dollars.
Cunningham said in his testimony "Human exploration is the most expensive space project, and therefore the most difficult to gain political support, and unless Congress decides to invest in it. more money ".
Referring to the March Missions, Cunningham adds: NASA is too weak to do all the things we've talked about here, "and it seems like presidents and Congress are not interested in 2004, for example , under the Bush administration, NASA spent $ 9 billion in the Constellation program
After designing, building and testing equipment for the manned space flight program, and after taking office of President Barack Obama, The government accountant reported 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 n & # 39, did not exceed the SLS program, but did not target
.So, repeated changes in NASA's costly priorities and cancellation after cancellation resulted in losses " was disappointed because they are p slow, "said Jim Lovell, Apollo 8 astronaut, at Business Insider in 2017:" I'm excited about anything. The real driver of 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 exploration lunar has always been lukewarm
. Only 53% of Americans believe that the program is worth the cost, and today 55% of Americans believe that NASA should make a comeback According to a June survey, the moon is a priority, even if only a quarter of Between them think that it should be a top priority, but 44% of those surveyed think that sending astronauts to the moon should not be at all.
NASA's budget is not the only reason people do not return to the moon: it's also a deadly trap for humans, 4.5 billion years old, and should not be underestimated. But the biggest concern is what the effects of meteorites, the so-called moon dust, have created.
Madhu Thanjavilu writes at p. M 2014: "The moon is covered with an upper layer of talc dust, electrically charged by interfering with the solar wind and other factors, and spoils the spacecraft very quickly." [19659002Thereisalsoaproblemofsolarlight[14]
Astronauts will undoubtedly return to the moon, then to Mars, it is only a matter of time.
Lovell said, "I think at the end things will come back, and will return to the moon, and will eventually go on Mars, t not in my life, but hope to succeed."
