Human space travel to Mars is feasible within decades. Developing advanced, regenerative life support systems is crucial for long-duration missions, integrating physical, chemical, and biological processes for reliability.

Area of Science:

  • Space exploration
  • Life support systems engineering
  • Human factors in spaceflight

Background:

  • Human space travel to celestial bodies like Mars is a long-term goal.
  • Preliminary analyses suggest Mars missions could launch between 2011 and 2016.
  • Key challenges include technical capabilities, physiological impacts, and reliable life support.

Purpose of the Study:

  • To explore structural elements for Mars mission life support systems.
  • To identify appropriate features for long-duration space travel life support.
  • To assess the evolution of life support from current to future systems.

Main Methods:

  • Review of current and projected technical capabilities for space travel.
  • Analysis of human physiological and psychological responses to the space environment.
