Two WEEKS in a suit?! Why????? Pardon my outburst. . .I meant no disrespect. I have been working on this issue for awhile and am currently pursuing this approach: It's called the 50/50 design. The spacesuit begins with a pressure/thermal protection garment with an oxygen breathing system, small heat rejection module and CO2 scrub unit. Very basic. This unit is worn during launch from Earth, all maneuvers in space and the lunar landing. Maximum capability for each O2 fill is only two to four hours, depending on level of activity.

On the Moon - before doing anything else - the astronaut must access a pre-landed logistics module and add several elements to the basic suit. These include larger life-support module able to sustain ten hours of activity per charge, a hard, one-piece upper 'carapace' that has computer, with head-up display, communications and even external lights. This unit is bulky, relatively heavy and completely out of the question for use during lunar flight; it stays on the Moon and is used over several missions.

A second unit attached to the right hip section is a thermal management system about the size of a loaf of bread but conforms to the shape of the hip. It cycles a 60/40 water/glycol mix through a series of bladders capturing the astronaut's excess body heat.

A third unit on the left hip is the waste management system. You can probably guess how that works. In the front, between the two sections just described, is a tool box.

When this unit is attached, the astronaut switches to an oxygen/ntrogen mix that is lower than terrestrial pressure with a higher O2 percentage.

During flights, if there is a problem with the cabin pressurization, the astronaut simply umbilicals dirctly to the spacecraft O2 supply, bypassing the cabin distribution system.
