Summary

Space Shuttle air quality remained safe for astronauts, with contaminant control procedures effectively managing volatile organic compounds and particulate matter. Minor exceptions noted, but overall, containment measures for Spacelab experiments were successful.

Area of Science:

  • Space environmental science
  • Astrobiology
  • Aerospace medicine

Background:

  • Space Shuttle cabin air quality is crucial for crew health and performance.
  • Chemical contaminants and particulate matter can degrade the Shuttle environment.
  • Previous studies highlighted potential risks from airborne substances.

Purpose of the Study:

  • To assess the effectiveness of contaminant control procedures on Space Shuttle missions.
  • To measure volatile organic compounds (VOCs) and analyze particulate matter in the Shuttle atmosphere.
  • To evaluate the impact of Spacelab experiments on air quality.

Main Methods:

  • Atmospheric sampling during STS-40 and STS-42 missions.
  • Gas chromatography-mass spectrometry for volatile organic compound analysis.

  • Filtration and chemical analysis of airborne particulate matter.

    • Main Results:

    • Air was generally toxicologically safe, with one exception due to a malfunctioning refrigerator.
    • Trace amounts of biological material (rat hair, food particles) and growth media were identified.
    • Low levels of particles from Spacelab experiments confirmed effective containment.

    Conclusions:

    • Space Shuttle air quality management systems are effective in maintaining a safe environment.
    • Spacelab experiments had minimal impact on overall air quality.
    • Contaminant control procedures successfully mitigated risks to crew health and performance.
