Photoshop FIle of the TL9 Crew Vacc Suit.

Photoshop file (gimp compatible) for TL9 Crew Vacc Suit

Traced with a lot of liberties from Albin Merle's 3d Rendering of the Advanced Crew Escape Suit (which should give you adequate inspiration). 

I realized Vacc Suits need to be High contrast as a safety precaution.

as I examine the EMU for my next work, I realize a lot of things as I tinker and trace over the EMU. 

1) no gravity (EVA usage) means legs and but serve to direct some 

2) legs are for stability in low g or when you need to magnetic walk to conserve on delta-v propulsion (walk instead of waste gas). 

3)  the backside can be a much larger area for (as some EVA suits are designed) both for entrance and life support. There is no "sitting" in this suit and expandable fabric space can be placed in the "trunk". 

Basically, the Spacer can pull out their legs from the pants and self-comfort and first aid. Cleaning up after "relief" is easier.  

It is pretty much a Vehicle than suit. 

4) the exoskeleton aids movement in a small pressurized vehicle of the EMU. At first the exo-skeleton will assist in comfort as you move the articulated parts of the suit. Its not like moving around 5-10kg strapped on your arms (the extra mass being a workout but also making fine manual work difficult) 

As the exoskeleton gets more sophisticated and advanced workers can now join, close, seal, etc... more and more with the strength of the suit. Again the right tools mean less force and accidents. When you overexert strength you sacrifice control, but when a machine is doing the heavy lift you focus on telling it to stop. 

as you expend more effort you focus on having more leverage and muscles for the job instead of having more control over the job. 

The best example is safety with sharp knives over dull knives. The more force you need (Blunt knives) the more accidents tend to happen. 

5) mechanical hands will be the norm. the Spacer's hands are protected with a layer of controls. grip strength and exoskeletons make a laborer able to do most straightening out and labors without expending Delta-V reaction mass (which is so hard to get to space in the early years). 

I realized so many things in the exercise.
