Colonizing Mercury Is a Better Prospect Than Colonizing Mars

Mercury is a better option for colonization than Mars because of the abundance of solar and thermal energy and availability of water.

Mars has less available water and would require more reliance on nuclear energy because there is significantly less solar energy and heat. This would eventually require mining although Mars is believed to have less uranium than Earth. If energy is costly and natural resources are scarce, prospects of building a sustainable colony for a large group would be very challenging.
