[citation][nom]jimmysad[/nom]well if they did it 40 years ago, dont you think they would constantly go back and forth landing people on the moon with some LIVE footage? [/citation]
They
were doing that with the Apollo program. 11 wasn't the only one to land on the moon, 5 more Apollo missions did. But even by the time of Apollo 13 there was already waning interest by the public and television coverage was not what it had been just two missions prior. All of that changed, of course, once 13 blew up in space and there was a frantic scramble to help the astronauts pilot the remains of their ship back home safely.
The last mission to land men on the moon was Apollo 17. Immediately after that program ended, NASA began launches for the Skylab program. We kind of followed the Soviety lead: after moon mania subsided, it was all about space stations and, later, reusable shuttles. NASA hasn't used rockets for manned missions since the Shuttle program, which turned out to be unfortunately because for all their heavy-lift capability and technological awesomeness they turned out to be more expensive and complicated to use than manned rockets. That's why the shuttle's replacement design is the classic rocket+capsule combo that works so well.
[citation][nom]jimmysad[/nom]i mean why not, they did it 40 years ago, it should be a breeze to do it now.[/citation]
There have only been six successful manned moon missions, ever. That's hardly enough experience to make something like a lunar mission "a breeze," even if our computer technology is more advanced. Despite the relatively simple physics of rockets, a system like the Saturn V or any comparable moon rocket is enormously complex and expensive.
The Soviet version was so complex, in fact, that it didn't work.
One of the primary reasons for the Space Race was the drive between two world superpowers locked in a ridiculously absorbed state of one-upsmanship. Another, often unspoken, reason was the potential military applications that lunar launch and landing technology could yield. With the US beating the USSR as "First" to-and-from the Moon, the public drive flagged. With the collapse of the USSR, there was essentially no military application for the moon that seemed to be worth funding (besides which,
an existing treaty banned a lot of that military use for the moon).
So basically the two biggest motivators were already gone by the time Apollo wrapped up.
[citation][nom]jimmysad[/nom]i saw something on discovery channel that next moon landing is slated for 2020...i mean why so far away. NASA should have conquered moon landing by now, dug for gold and oil by now, and landed on Mars by now. They should have had the enthusiasm they had 40 years ago and raced to be first to dig the Moon and land on Mars.[/citation]
The Moon lacks most commercially important minerals (and obviously, without life it'd have no fossil fuels) because of the way it was formed, so there's no point in using it as a source of ore for Earth-bound projects. Mars is an incredibly more difficult undertaking than the Moon, on one level just because of the enormous distances involved (it would have to be a multi-year mission for a round trip). And public enthusiasm has, as I said, waned drastically since "winning" the space race. When Bush talked about landing men on Mars, people laughed it off. Today you have a lot of people griping that NASA gets way too much money as it is, which would have never happened back when we had to "beat" the Soviets. The enthusiasm has almost totally evaporated, and it's not really NASA's fault either.
