Earth-supported colony

The Earth-supported colony is a concept of starting the colonization of Mars. It can be either a manned one-way mission or a colony with regularly changed crew.

Comparison with other concepts

Compared with an autonomous colony this concept has the following advantages:

• Fewer new technology must be developed
• Smaller mass and volume of initial transportation
• Support can be adapted
• A smaller group of settlers is possible

and the following disadvantages:

• Long term costs
• The colonists have fewer opportunities for their own advancement. They are subject to leadership from Earth.

Types

Energy and food support

The colony receives regularly fuel and food from Earth. Greenhouses are not necessary. Energy generation is easier, perhaps with nuclear power.
