tries to limit the duration of its spacewalks to about 6 1/2 hours on average because
astronauts become tired working in their bulky spacesuits. Future astronauts
may have <A href="http://www.space.com/missionlaunches/080613-spacesuits-constellation-contract.html">more
flexible spacesuits</A> to work with, but researchers still look to counteract
the muscle fatigue in the shoulders, arms, wrists and hands.</SPAN></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/6EC14372-016C-45F3-A906-9403CF1AD923/blog/" title="blog or email this clip"><img src="http://content6.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>
