Mars?

[popeyespappy]

Trying to come up with the best ways to colonize Mars is sort of like sitting round discussing how to build a suspension bridge out of mercury - it isn't going to happen.

At -40C mercury is a solid with properties similar to tin. Since the average temperature on Mars is -60C building a bridge out of mercury on Mars isn't as far fetched as one might assume.

And yes, the daytime temperature on Mars can and does exceed the melting point of mercury so you better build your mercury bridge in the shade...

And there is still the unaddressed biological issue of 0.38g.

And it's a biggie too. 4 to 6 months on ISS averages 30% loss of strength and 15% loss of muscle mass. Exercise doesn't help much either. Mars wouldn't be nearly as bad but long term exposure to 38% gravity wouldn't be good for a human.

Genetic engineering?
