Hi,

Could someone help be to find the correct version ?

I read at http://en.wikipedia.org/wiki/Extrave..._Mobility_Unit
that the apollo EVA suit was made of 21 layers. It is the first time I read
this.
Most websites tell that the A7L suit used for EVA during the moon missions
had only 7 layers
Question : what suit used Apollo crew during EVA ? An A7L made of 7-layers
or something else ?

Do you also confirm that it was only for ISS that NASA used a 14-layer suit
to made the EMU.
Some speak of a 15 layer suit ? Was the original EMU made of 14 layers, and
the lastest one, a bit lighter named ISS EMU made of 15 layers ?

Thanks for your light

Thierry


First of all, man, stay the hell away from Wikipedia, unless you're
looking for info on pressure suits used by Star Trek characters, or
information on pressure suit technology in Klingonese. Large numbers of
junior-high and high-school kids (at least in the USA) are being
summarily flunked for citing Wikipedia on their research papers due to
its editing methods and perverse refusal to publish articles written by
actual experts in their subjects.

That said, peep:http://www.astronautix.com/craft/a7l.htm
There were several mods to the A7L for intra- and extra-vehicular use;
there was the standard one that you always see them in in all those old
pictures, there were at least two mods for use in lunar EVA involving
micrometeoroid-protective coverings, cleated overshoes and helmet
sheild/visor assemblies, and there were mods further down the line for
use in SkyLab's different EVA requirements.

'Fraid I don't recall much about the Shuttle/ISS EVA suits other than
their being far more advanced despite their outward resemblance to the
old Apollo EVA gear.





Wishing they'd been able to put a camera on Armstrong's helmet,
