Why did the USA stop going to the moon in the 70s?
user
There were political, economic, and scientific reasons. The USSR sent an unmanned mission to the moon in the 1970s, which prompted the US government to invest in the Space Shuttle program. But when the Shuttle program was deemed a failure, there was less of a need to invest in space programs, and so the US government stopped sending people to the moon.

Well, it’s complicated. In the beginning, the Space Shuttle was expected to be a fantastic success, but it ended up getting so much extra time and money that it wasn’t as useful as expected.  It also had a lot of bugs, especially with the engines.

It had some technical problems, which were difficult to overcome. But some people think the design was inherently flawed, because of problems in software architecture.
