re: A spacesuit for the Moon...
I finally got a copy of Vol. 47 No.12 December 2005 Spaceflight.
Read the article.
A really good one by D. Day
John Young is probably right. Over all the suits designed so far are heavier than the A7LB and with many more bearings and I'm willing to bet will fail sooner than the weeks they should last.
Maybe it's time to seriously look at MCP suits which wouldn't need bearings. Still they would have dust permeation problems.
