The exploration of Mars is just getting started. I have no doubt that terraforming will be a big part of any colonization attempts.

Outside of Earth it is the most promising piece of real estate in the Solar System. It has all these things we need:

• A 24.65 hour day (we need the circadian rhythm for health).
• Water (H₂O) in relative abundance (absolute necessity).
• Decent gravity (1/3 Earth normal).
• Axial tilt for seasonal changes - would come in handy when terraforming is advanced.
• Some atmosphere (though thin and unbreathable) to start with.
• Building materials such as rock and forgeable metals.
• Geologic stability (no active volcanoes).
• Close enough to the Sun for terraforming to have a chance of success.

  Of course, Mars has a lot of things that are a disadvantage to us:

• No magnetic field to trap charged solar particles.
• No ozone layer to reflect UV and gamma rays.
• Water though abundant as permafrost must be accessed.
• Average temps of -67 Fahrenheit are like winter in Antarctica.
• Mars' atmosphere is deficient in oxygen and nitrogen.

  The jury's out on how long terraforming would take. It's dependent on so very many factors, such as how much effort we can put into the project, effectiveness of greenhouse gases, how well genetically tailored bacterial colonies survive, etc.

Thank you!

I'll have to think about going there and taking you up on the offer. I just recently got a job doing yard work, and I know I can go for a few days if I give the boss enough notice. If it snows I can't work anyway as he refuses to shovel snow.
