Thin & Toxic Atmosphere
"Martian air is 100 times thinner than Earth's and composed of 95% carbon dioxide. Without a pressure suit, your blood would boil instantly at body temperature (Armstrong Limit), and you would asphyxiate within minutes."
Key Data
The Hostile Reality
Outside the protective cocoon of Earth's magnetosphere, crews are exposed to two sources of lethal ionizing radiation.
1. Armstrong Limit
Atmospheric pressure is so low (0.6% of Earth's) that bodily fluids boil at skin temperature. A full pressure suit is mandatory for any EVA.
Current Tech (TRL 9)
- MOXIE: Prover oxygen extraction from Martian CO2.
- Sabatier Reactor: Combining CO2 with Hydrogen to produce Methane and Water.
Future Engineering
Magnetic Shield: An artificial magnetosphere at L1 could allow the atmosphere to rebuild over centuries.
