How to raise the temperature on Mars?
To find out more information on this look up Terraforming. By the way, on the equator, the temperature usually ranges from +10 C to -50 C. The poles are much colder. To warm Mars, you need to: — Have more heat hit the planet, or — Have the heat that hits it stay longer, or both. Moving Mars closer to Earth is basically impossible but you can use giant mirrors 100 or 200 kilometers in diameter to reflect sun light that would have missed Mars back on to the surface. Using the ‘Statites’ Proposed by Dr. Robert Forward, you can have a mirror over the north pole and south pole reflecting light there all year long. Assuming that they are 125 km in diameter (massing the same as a super tanker) these by themselves should be enough to knock Mars into a warmer climate regime. (See below.) To have the heat stay longer we need to increase Mars’ green house effect by thickening its atmosphere. Fortunately, this now looks to be very easy. A huge amount of carbon dioxide (CO2) is locked up in Mars’
