AAE450 Senior Spacecraft Design Kate Mitchell - 6 Totals Breakdown *Volume of the Human Factors Systems is encompassed by the structures volume **Total values for the propulsion systems can be found in the files for the dE, aM, dM, aE and EP data-sharing pages ***Calculations for the total mass of each transfer vehicle for each mission are attached Example of TV Total Mass Calculation – TV 1***

7. AAE450 Senior Spacecraft Design Kate Mitchell - 7 Spacesuit Comparison Full Gas Pressure Suits Advantages –Proven technology –Various designs/sizes Disadvantages –Heavy and bulky –Difficult to donn/doff –Pre-breathe necessary –Full suit pressurization –Lack of mobility, flexibility, dexterity –Loss of oxygen if suit is damaged –High metabolic requirement MCP Suits (“Bio-Suit”) [3] Advantages –Lightweight –Minimal metabolic cost –Improved mobility, flexibility, dexterity Disadvantages –Untested technology –Difficult to donn/doff –Areas of concavity

8. AAE450 Senior Spacecraft Design Kate Mitchell - 8 Spacesuit Design Chosen Mechanical Counter Pressure Suits (“Bio-Suit”) –Overall, the Bio-Suit was found to be a better suit for exploration *Photos taken from “EVA Research at MVL” website [3]
