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

Spacesuit Design Chosen

Mechanical Counter Pressure Suits (“Bio-Suit”)– Overall, the Bio-Suit was found to be a better suit for

exploration
