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
