              is successive layers of Nextel, a material commonly used as insulation 
              under the hoods of many cars, spaced between several-inches-thick 
              layers of open cell foam, similar to foam used for chair cushions 
              on Earth. The Nextel and foam layers cause a particle to shatter 
              as it hits, losing more and more of its energy as it penetrates 
              deeper.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://spaceflight.nasa.gov/history/station/transhab/"><P><FONT size="-1" face="Arial, Helvetica">Many layers into the shell 
              is a layer of superstrong woven Kevlar that holds the module�s shape. 
              The air is held inside by three bladders of Combitherm, a material 
              commonly used in the food-packing industry. The innermost layer, 
              forming the inside wall of the module, is Nomex cloth, a fireproof 
              material that also protects the bladder from scuffs and scratches.</FONT></p> <P><IMG width="580" height="203" src="http://spaceflight.nasa.gov/history/station/transhab/images/transhab_iss_config.jpg" alt="Proposed TransHab configuration on ISS" /></P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/77B4D45A-37EA-429F-80FA-B31BC10C063D/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
