Health Care
Health care is required for the well being of the Mars settlers. Health care facilities may include dispensaries, nursing homes and hospitals.
The Autodoc is a concept that may find application on Mars. Health care represents an important social cost. As the population of the Mars settlement ages, health care problems and costs will increase. Children born on Mars may have special health care requirements.
Mental health is also an important issue in a Martian settlement.
As a service, health care consumes a large part of the budget of modern societies. This would also be the case on Mars.
