Why Nobody Has Gone To Moon Again in More Than 45 Years !

You might be not aware of the fact that nobody has gone to moon for more than 45 years and the reasons behind this are shocking and you must know what’s actually reality about this and “Why Nobody has gone to moon again in more than 45 years ?”

More than 45 years after the most recent crewed moon landing – Apollo 17 in December 1972 – there are plenty of reasons to return people to Earth’s giant, dusty satellite and stay there.

Researchers and entrepreneurs think a crewed base on the moon could evolve into a fuel depot for deep-space missions, lead to the creation of unprecedented space telescopes, make it easier to live on Mars, and solve longstanding scientific mysteries about Earth and the moon’s creation. A lunar base could even become a thriving off-world economy, perhaps one built around lunar space tourism.

Here Are the Reasons—

  1.  A tried-and-true hurdle for any spaceflight program, especially for missions that involve people, is the steep cost.

A law signed in March 2017 by President Donald Trump gives NASA an annual budget of about $19.5 billion, and it may rise to $19.9 billion in 2019.

Either amount sounds like a windfall – until you consider that the total gets split among all of the agency’s divisions and ambitious projects: the James Webb Space Telescope, the giant rocket project called Space Launch System, and far-flung missions to the sun, Jupiter, Mars, the Asteroid Belt, the Kuiper Belt, and the edge of the solar system. (By contrast, the US military gets a budget of about $600 billion per year. One project within that budget – the modernization and now expansion of America’s nuclear arsenal- may even cost as much as $1.7 trillion over 30 years.)

Plus, NASA’s budget is somewhat small relative to its past.

A 2005 report by NASA estimated that returning to the moon would cost about $104 billion (which is $133 billion today, with inflation) over about 13 years. The Apollo program cost about $120 billion in today’s dollars.

2.  The political tug-of-war over NASA’s mission and budget isn’t the only reason people haven’t returned to the moon. The moon is also a 4.5-billion-year-old death trap for humans, and must not be trifled with or underestimated.

Its surface is littered with craters and boulders that threaten safe landings. Leading up to the first moon landing in 1969, the US government spent what would be billions in today’s dollars to develop, launch, and deliver satellites to the moon to could map its surface and help mission planners scout for possible Apollo landing sites.

But a bigger worry is what eons of meteorite impacts has created: regolith, also called moon dust.

There’s also a problem with sunlight. For 14.75 days at a time, the lunar surface is a boiling hellscape that is exposed directly to the sun’s harsh rays – the moon has no protective atmosphere. The next 14.75 days are in total darkness, making the moon’s surface one of the coldest places in the universe.
