A duty to enhance? Genetic engineering for the human Mars settlement

Area of Science:

• Astrobiology
• Human Physiology
• Bioethics

Background:

• Off-world human habitation presents significant physiological and psychological challenges due to environmental differences.
• Lack of evolutionary adaptation to space environments can lead to adverse health effects for settlers.

Purpose of the Study:

• To explore the potential of genetic technologies to facilitate human adaptation to space environments.
• To examine the ethical implications of genetically modifying space settlers for enhanced well-being and survival.

Main Methods:

• Conceptual analysis of existing and emerging genetic technologies.
• Ethical framework evaluation for human genetic enhancement in space.

Main Results:

• Genetic technologies offer a pathway to mitigate health risks like radiation damage and bone/muscle loss in space.
• Potential for significant genetic modification of off-world communities exists.

Conclusions:

• Genetic enhancement may be crucial for the health of space settlers, especially children born in settlements.
• Ethical concerns include the risk of a eugenicist agenda and the rights of individuals to refuse genetic modifications.
