Area of Science:

  • Space settlement design
  • Occupational and environmental health
  • Closed ecosystem modeling

Background:

  • Analysis of fundamental design assumptions for lunar and Mars settlement concepts.
  • Evaluation against occupational and environmental health concerns.

Purpose of the Study:

  • To proactively integrate public health concerns into complex technological development for space settlements.
  • To identify critical challenges in closed ecosystem and resource utilization (mining, material processing, manufacturing) for long-term space habitation.

Main Methods:

  • Analysis of five technical areas: science projects, habitat/construction, closed ecosystems, mining/material processing/manufacturing (MMM), and human factors.
  • Comparison of design assumptions with a model list of health concerns.

Main Results:

  • Proactive integration of health concerns can lead to long-term cost savings.
  • Current approaches to closed ecosystems and MMM for lunar settlements require significant revision.
  • Space habitation health and technology issues are fundamentally similar to those for Earth's 21st-century habitation.

Conclusions:

  • A paradigm shift is necessary for developing sustainable lunar settlements.
  • Future space exploration health challenges are intrinsically linked to Earth's environmental sustainability.
  • Development of probabilistic ecosystem design models is recommended over traditional closed-circuit models.
