Space suit question

Here's my current wallpaper:

There's some controvercy about weather or not Armstrong and co. went to the moon or if they just orbited the earth
and faked the photos in a studio. There are certainly a few NASA mistakes regarding the photos if nothing else.
There are some videos on Youtube if You're interested, just search fake + moon + landing etc.

I have a question that's allways puzzled me: why is the spacesuit not looking inflated? If You have pressure inside the suit and no outside
then the suit will inflate like a balloon making moving around impossible. I don't get it.

I made a poll also - I think they went there (because Armstrong does not look like a guy who would pull a stunt - could be wrong though)

Someone give me a good explanation on the question, pls :shock:
Cheers.

hi! the spacesute is not filled with air.. it has just the air he needs to breath with a "rebreather". moreover the suit is quite thick.

the mythbusters made a special episode on this 3 weeks ago where they explain why they think that they were there.. the explanations are all quite logic. so i agree on the yes.

Lol. Sharky. I was just about to put in mythbusters too. And indeed i also say yes. :D

I didn't see that Mythbusters episode. It hasn't been screened in Australia yet.
But I do know that the moon landings are factual.
Landing people on the moon isn't an especially hard technical obstacle. It just costs a lot of money, and some lives in initial tests. And the USA is prepared to pay those kinds of prices, and they have the technical expertise.
All the other countries can confirm that the USA put people on the moon, it is not just the USA saying that.
They even have rocks brought back from the moon.

It is true...

Anyone who thinks otherwise will get punched in the face by Buzz Aldrin

See this: http://www.youtube.com/watch?v=ZOo6aHSY8hU

But, my Grandpa worked for NASA for 25 years, and all he did was do moon research...

Of course they went to the bloody moon ffs. What a load of toss these 'consiracy theorists' crap on about!? Its not rocket science to get there (er, well, actually...)..

Anyone who claims this was a conspiracy needs a checkup from the neck up - I bet they are all members of the 'Flat Earth Society' as well.

BAM!! http://www.badastronomy.com/bad/misc/apollohoax.html

Stupid Fox network, airing crap. http://www.badastronomy.com/bad/tv/foxapollo.html

I haven't seen the Mythbusters on it, don't have cable or satellite, and their DVD releases are stupid. (I am unwilling to watch it on youtube like my brother does. youtube sucks for real shows, especially technical ones where you might like to SEE what is happening.)

I always thought that if they could fake the moon landing so realistically, how come movies still look like crap?

FFS someone answer my question!!!
Don't You ppl know what vacuum will do:

BTW there's so much we don't know:
http://www.youtube.com/watch?v=07JUHqow ... id=2293267

I'll ask again:
How can the soft fabric of the space suit keep the astronaut from exploding. I don't get it. Never have.

If a submarine dive too deep it gets crushed. If a astronaut fly to high he'll explode. Only he doesn't apparently. Help me dammit.
This is the biggest unanswered question in my life. I know 'bout the UFO's :D

And thanks for voting!

@ Sharky: thanks but there's 1 atm. pressure in the suit or the gas in his intestines would expand dramaticly.

From my books here the suit is probably an evolution of the high altitude pilot suit (some of these suits also compensate for high G forces too.), the suit will hold in the body to keep the right pressure on it.

If I recall correctly air pressure is 14 psi, but the suit is probably only ~3 or 4 psi, there is a regulator at the neck. If it was inflated like a ballon you couldn't move without very troublesome mechanical joints. The undersuit keeps in your body I think, but 3 or 4 psi should help.


Edit: From this site it seems that you "explode" because your fluid boils at reduced pressure (thus high-altitude pressure boilers), so prevent the fluid from boiling and you shouldn't explode :)

Pressurized Atmosphere
The space suit provides air pressure to keep the fluids in your body in a liquid state -- in other words, to prevent your bodily fluids from boiling. Like a tire, a space suit is essentially an inflated balloon that is restricted by some rubberized fabric, in this case, Neoprene-coated fibers. The restriction placed on the "balloon" portion of the suit supplies air pressure on the astronaut inside, like blowing up a balloon inside a cardboard tube.

Most space suits operate at pressures below normal atmospheric pressure (14.7 lb/in2, or 1 atm); the space shuttle cabin also operates at normal atmospheric pressure. The space suit used by shuttle astronauts operates at 4.3 lb/in2, or 0.29 atm. Therefore, the cabin pressure of either the shuttle itself or an airlock must be reduced before an astronaut gets suited up for a spacewalk. A spacewalking astronaut runs the risk of getting the bends because of the changes in pressure between the space suit and the shuttle cabin.
