re: What kind of Pressure suit or Spacesuit for the CEV?
Currently they plan to use a version of the Mark III on the Moon's surface. I'm not sure if it will be the ZPS* Mark III (210 pounds and 10 psi) or a lower pressure lighter redesign. This suit is a hybrid with the better parts of soft and hard suits. Still it has many bearings and a high CG which will cause the same kind of falls the Apollo era astronauts experienced with the A7L and A7LB suits. If they don't get serious and solve the problems that plagued the Apollo suits. I don't see how they can fulfill the mission requirements they have set themselves.
