Cool. 😎 We can actually resolve an astronaut trackway from orbit now.

I think that's the best way to describe in one sentance why America is so cool.
They fired up the secret movie studio again for some pictures? 😛
We leave trash everywhere we go.
I do not understand why we stopped going to the moon. Its like we stopped a program that could have taken mankind further then we have ever gone.
Cost,
and the near certainty that if we kept flying Apollo-type missions there would have eventually been a fatal accident that would cancel out the propaganda value of beating the Soviets to the moon.
Texashiker:
I'm as pro-space exploration as you can be, the reasons I gave were the ones that policymakers followed.
The death of Apollo began with the decision to shut down Saturn V production after the initial run of 15 rockets was complete. That choice meant that there was no way NASA could've gone beyond Apollo 20, or Apollo 19 once the decision was made to use a Saturn V to launch Skylab. When Apollo 18 and 19 were canceled it was supposedly to save money, however a big reason the politicians did it was because two more moon landings wouldn't have made the US look much better whereas if one of those flights had failed it would've been a huge PR black eye. The amount of money saved was fairly small because all of the hardware for those flights had already been built. After the spectacular success of Apollo 15 (in terms of scientific return it was probably NASA's most successful manned mission ever) there was even talk of canceling Apollo 16 and 17, but thank god that didn't happen.
What really slays me is that although Apollo was spectacularly expensive a huge part of that cost was R&D and infrastructure construction. Once the Saturn V was designed and the launch pads, VAB and other structures were built the cost of additional moon missions would've been much lower. It would have never been cheap, but IMO a great nation such as ours can and should devote a small part of its national budget to great endeavors such as the human exploration of space.
The money that was eventually spent on the shuttle could've been put to much better use building a second batch of Saturn Vs. Those rockets could've used the more powerful F-1A engines, which in turn would've meant carrying more weight to the moon and more ambitious mission possibilities. Former NASA administrator Mike Griffin did a paper a while back where he showed that if we hadn't bothered with the shuttle we could've spent the 1970s launching a couple of lunar missions per year AND maintaining a Skylab type program, while at the same time working on the technology that would've made interplanetary missions possible in the future.
Edit: While I think that the lunar program was worth the risk, Apollo was insanely dangerous for those involved. Of all the missions they did Apollo 8 still boggles my mind. It was only the third flight of the Saturn V (and the first time they'd put people on one!) and only the second manned flight of the Command & Service Module, and they took that think all the way to the moon! People talk about how NASA had an unsafe culture during the shuttle program, but the way they bent mission rules and took chances to get to the moon before 1970 makes the dangers of the shuttle pale in comparison. Then again they were honest with themselves about it being a high-risk, experimental program. There was never this nonsense of spaceflight being "routine" the way it was supposed to be with the shuttle.
Those images are photoshoped, everyone knows the lunar landing was faked.
I do not understand why we stopped going to the moon. Its like we stopped a program that could have taken mankind further then we have ever gone.
Not to mention the lunar astronauts were nearly irradiated to death several times because we didn't know much about solar flares. I think I also read that most of the lunar astronauts developed cataracts due to insufficient radiation shielding.
We would never subject people to that kind of danger with today's open media blowing the whistle on everything they get their hands on. This is why space exploration has become so prohibitively expensive. Hell, we weren't even sure if we could get their first people on the moon back - Nixon had a speech ready to go telling the men on the moon they would die heroes and a permanent monument to man's achievements.
Brave men like this aren't allowed to exist anymore.
NASA took big risks with the shuttle program as well. STS-1 was the first time the shuttle had EVER flown, and they put people on it! How's that for danger? That flight has gone down in history as a triumphant achievement but it came close to being a catastrophe at several points in the mission. It actually could've been flown unmanned, but interestingly enough two of the loudest voices speaking out against an unmanned test mission were John Young and Robert Crippen, the first flight's crew.
As for the Apollo 11 astronauts NASA certainly knew that they could get them back, they simply had to prepare for the possibility of something not working. It's not like they sent them to land and then figured "aw shucks, let's hope this rocket engine fires."
Sorry but that's nonsense. Most of the Apollo astronauts have lived to ripe old ages. 9 of the 12 men who walked on the moon are still alive, and 2 of the 3 who died passed away for reasons that couldn't have had anything to do with radiation (Pete Conrad was killed in a motorcycle accident and Jim Irwin died of a heart attack.) I suppose it's possible that Alan Shepard's leukemia was caused by radiation but 74 isn't an unnaturally young age to die.
At least 39 former astronauts have suffered some form of cataracts after flying in space, according to a 2001 study by Francis Cucinotta of NASA's Johnson Space Center (see journal references below). Of those 39 astronauts, 36 had flown on high-radiation missions such as the Apollo Moon landings. Some cataracts appeared as soon as 4 or 5 years after the mission, but others took 10 or more years to manifest.
