The bioethics of enhancing human performance for spaceflight

Area of Science:

• Aerospace Medicine
• Bioethics
• Human Performance Enhancement

Background:

• Military aviation and spaceflight necessitate human performance enhancement.
• Methods include selection, training, equipment, pharmacology, surgery, and future genetic manipulation.
• Ethical acceptability varies for each enhancement modality.

Purpose of the Study:

• To examine human performance enhancement methods in aeromedical contexts.
• To analyze the ethical acceptability of these methods.
• To guide aeromedical practitioners in developing ethical codes of practice.

Main Methods:

• Review of human performance enhancement tools (selection, training, equipment, pharmacology, surgery, genetic manipulation).
• Ethical analysis based on principles of autonomy, non-maleficence, beneficence, and justice.
• Consideration of societal and individual perspectives on risk and consent.

Main Results:

• Performance enhancement methods present a spectrum of ethical acceptability.
• Individual consent does not always equate to societal or ethical acceptability.
• Balancing societal needs with individual ambitions is complex.

Conclusions:

• Aeromedical practitioners face complex ethical dilemmas regarding human performance enhancement.
• A morally justifiable code of practice is needed.
• Ethical frameworks must integrate societal needs, individual goals, and corporate objectives.
