Project 006 Research on Mars Environment

I researched on Mars Environment in order to make a story of my final animation. I found that Mars environment is quite different from that of Earth.

http://en.wikipedia.org/wiki/Mars

  • Mars’ rotational period and seasonal cycle are similar to those of Earth.
  • The gravity is 40% of that on Earth.
  • No magnetic field
  • Fe2O3 or hematite or rust makes Mars look reddish orange.
  • The surface material is basalt.
  • The surface pressure is less than 1% of Earth. Since the atmosphere is thin, heat transfer is little and insulation is poor.
  • The temperature is lower than that of Earth, ranging from -140 C to 20 C.
  • Water exists as either gas or ice and can’t exist as liquid. Large portion of surface ice is two polar caps.
  • The composition of the atmosphere is 95% of CO2, 3% of N2, and 3% of Ar. This is quite different from that of Earth; 78% of N2, 20.9% of O2, 0.9% of Ar, and 0.04% of CO2.
  • Little amount of methane has been detected.
  • The dust storm both over a small area or the whole planet

My animation is going to depict the situation several decades after the beginning of terraforming. People have built inhabitable environment somewhat, but it has just begun, and far from a matured city. The features of the martian environment I mentioned above have following influence on the martian human life.

  • The existance of iron is good for making steel, thus good for various industries including architecture and civil engineering.
  • 42-52% of the weight of basalt is SiO2. Large amount of glass and brick can be made out of basalt, as described in Red Mars.
  • In order to stand the dust storm, the buildings should be short and thier windows should be small, like a pillbox. Since the outside is under low air pressure and cold, the wall shoud be thick for the sake of insulation.
  • Since the air is really thin, wing and propeller of airplane don’t work. Because of the lack of O2, jet engine doesn’t work, too. Rocket engine is the only option available.
  • Fossil fuel is not available on Mars. Available energy sources are solar electricity, atomic power, and possibly methane gas.
