Imagineering on Mars

Renewed Interest in Mars  - Why Go to Mars? - Living off the Land - Making Air to Breath 
Making Water Drink  - Making Food to Eat - Making Shelters to Live In - Heating Shelters 
Making ElectricityMars Scientific Data  - Martian Satellites

If a permanent colony of humans are to survive on Mars, they will need to live off the air, sand and rock resources on the surface of Mars. 

Imagineering on Mars discusses how engineers and scientists on earth could help the Martian settlers by developing the machines and factories to transform the stuff of Mars into life sustaining materials.

Mars Scientific Data

Mars/Earth Comparison

Surface gravity relative to earth = 0.377 (A 200 lb man on earth would weigh 75.4 pounds on Mars)

Mars Mass = 6.4 X 10^23Kg = 1.4^24 pounds

Earth Mass = 5.97 x 10^24Kg = 1.3 x 10^25 pounds

Mars Diameter = 6,794Km = 4,222 miles

Earth Diameter = 12,756Km = 7,927 miles

Mars Volume = 1.63 X 10^11 cubic Km
   = 3.9 x 10^10 cubic miles

Earth Volume = 1.08 x 10^12 cubic Km
   = 2.6 x 10^11 cubic miles

Mars average density = 3,933Kg/cubic meter
   = 245 pounds per cubic foot

Earth average density = 5,520Kg/cubic meter
   = 345 pounds per cubic foot

Mars escape velocity = 5.03 Km/sec
   = 3.12 miles/sec = 11,250 miles/hr

Earth escape velocity = 11.19 Km/sec
    = 6.95 miles/sec = 25,000 miles/hr

Mars average distance from sun = 2.28 x 10^8 Km
    =1.42 x 10^8 miles

Earth average distance from sun = 1.496 x 10^8 Km
   = 9.3 x 10^8 miles

Mars available solar power = 595 watts/ square meter
    = 55.3 watts/ square foot

Earth available solar power = 1,380 watt/ square meter
   = 128 watts/ square foot

Mars orbit time around sun = 687 days

Earth orbit time around sun = 365.25 days

Mars day = 24.62 hrs

Earth day = 24 hrs

Mars Average atmospheric temperature = 210K
   = -63C = -81F

Earth average atmospheric temperature = 288K
   = 15C = +59F

Mars Atmospheric Pressure = 6.7 mb
   = 0.097 pounds/sq in

Earth atmospheric pressure = 1014 mb
   = 14.7 pounds/sq in

Mars atmospheric Density = 0.020 kg/m3
   = 0.0012 pounds/cubic ft

Earth atmospheric density = 1.23 kg/m3
   = 0.0768 pounds/cubic ft

Mars atmosphere components by volume =

  • 95.32% Carbon Dioxide

  • 2.7% Nitrogen

  • 1.6% Argon

  • 0.13% Oxygen

  • 0.021% Water

  • 0.0003% Neon

  • 0.08% Carbon Monoxide

  • 0.01% Nitrogen oxide

Earth atmosphere components by volume =

  • 0.035% Carbon Dioxide

  • 78.1% Nitrogen

  • 0.93% Argon

  • 21% Oxygen

  • 1% Water, Typically

  • 0.0018% Neon

Mars distance from Earth = Minimum 5.4 X10^7Km Maximum 4.01 X10^ 8Km

Wind speed = 2 -7 m/s summer, 5 -10 m/s fall, 17 - 30 m/s storm

Mars nighttime low temperature = 184K  = -89C  = -128F

Mars daytime high temperature = 242K = -31C = -24F
