Using Thermochromic Materials for Mobile Space Suit Heating Applications

Salt Lake Community College

In past research we investigated and proposed the use of an intermediate environment [2]. It is termed an intermediate environment because it has the pressure of the living quarters but uses plentiful Martian air as the ambient. The use of an intermediate environment can solve the pressure requirement effectively. An intermediate environment pressurized with Martian air would provide sufficient external pressure, allowing the use of a thinner, light-weight suit. The astronauts would need oxygen or mixed gas masks, but would not need their bulky outside suits to provide counter pressure. This will allow improved mobility, dexterity, visibility and astronaut energy efficiency. An intermediate environment also has additional benefits in minimizing flammability concerns, minimizing decompression sickness, and saving cost on resources.
