Well, imagine shuttles had a failor rate like MS windows. There wouldn't be any shuttle left...

They are describing how they -did- design the lunar lander.

Well, in language a 2 year old could understand at least. >_>

i found it funny xD

I love the Scrapbook-Like graphics^^!

would you like to dive with a car that was used in the 60´s? cO

showing shuttle at the end is a bit ironic. but I cant still belive how this folks got it right almost every time. I mean you send a rover to another planet and it still works after 5 years, damn.

good video

As I said elsewhere in comments, nearly everything NASA does is a "test" in the engineering sense, nearly everything NASA produces is a prototype in the engineering sense. What NASA does is a bunch of simulations to see if their tests will work.

With cell phones you can truly test a prototype, you don't have to simulate it; but you can't test a rocket without launching it, so you simulate a launch to try to make your tests go well. I find NASA's failure rate to be astonishingly low.

Actually, part of what's so impressive about NASA is that it, in many ways, does things right on the first try. All our tests are simulations, not full tests.

If you have a cell phone prototype you have a very real test, you turn it on and see if it works; if you have a space ship prototype you don't just shoot it to the moon and see if it works, you do simulations that approximate the real thing; in that manner, most of what nasa does is prototypes that work (even if some don't, still amazing)

@ibtrippen This video needs to be shown to adults around the country!LOL!

This video needs to be shown to elementary school students around the country!
