Mars lacks only three things to make it a wonderful place to live.
Heat.
Carbon Dioxide.
Water.
The heat can be supplied by placing mirrors in a stationary orbit, to reflect sunlight onto the night side of Mars. This would be made of very thin sheets of aluminum.
The Carbon Dioxide could be supplied from the planet Venus, which has much more than it needs. Moving stuff around in the inner system requires nuclear rockets, and propulsion gases. (Carbon Dioxide is a very effective gas for propulsion.)
The water could be supplied from Earth. It is my answer to the shrill screams about global warming. (You've heard them: Global warming will melt the ice caps and flood the worlds port cities! -- Okay, say I, we'll send the ice caps to Mars. Next problem?)
Others, of course, will say, "Why bother?" --
1) Because we establish a presense in space, which will bring us resources, and possibly save our lives.
2) Because we will make two planets more hospitable to life (I'm not even counting Venus.)
3) Because it will create employment, and hope, and a better environment, right here on Earth.
Super Bump!
Well said!
That is actually a good idea.
