Title: TemperatureMoisture Acquisition System


1
Temperature/Moisture Acquisition System
  • Description
  • Miniature sensor that measures temperature and
    moisture levels in materials in which it is
    embedded
  • Application Benefits to Exploration
  • Determine moisture level and distribution in
    particulate or porous materials, including wicks,
    membranes, and fabrics
  • Flow indication with no moving parts
  • Determine composition of some simple solutions
  • Leak and contamination detection
  • Root zone moisture detection
  • Status
  • Currently being used to measure moisture levels
    in root modules and in fabrics

Condensing Heat Exchanger
Habitat air impinges on porous interface, water
vapor condenses in pores and is collected in
reservoir
Porous membrane condensing heat exchanger system
provides precise humidity control and direct
condensate recovery
Humidity control modules allow easy scaling and
distributed application
Plasma-enhanced Surfaces
  • Applications
  • Humidification
  • Dehumidification
  • Waste drying
  • Brine evaporation
  • Cloths drying

Prototype trash dryer
Hydrophilic and biocidal coatings
3
Miniature Mass Spectrometer
  • Description
  • Ruggedized, miniature mass spectrometer
    integrated into rack mount payload envelope to
    monitor trace concentrations of atmospheric
    contaminants of interest in closed environments.
    Integration with GC and other sensors would
    expand capabilities.
  • Application Benefits to Exploration
  • Identification of a broad range of volatile
    organic components in closed environments
  • Spacecraft Maximum Allowable Concentrations for
    Selected Airborne Contaminants (JSC 20584)
  • Plant contaminants (JSC Document 39349, Advanced
    Life Support Crop Growth Science and Technology
    Report)
  • -Monitoring volatile organic components
    detrimental to human health
  • -Analytical instrument for experimentation
  • -Monitoring contaminants harmful to plants at
    very low concentrations
  • Status
  • Conceptual development
