Water Damage

Water Damage

Water damage is a significant concern in space exploration. The presence of water in spacecraft or on planets can lead to various problems, including:

  • Corrosion of electronic systems
  • Microbial growth
  • Increased wear and tear on mechanical components

Detecting Water Damage

Early detection of water damage is crucial for preventing severe consequences. Various methods are employed to detect water damage:

  • Conductivity sensors: Measure changes in electrical conductivity caused by the presence of water.
  • Capacitance sensors: Detect changes in capacitance between two electrodes resulting from water’s dielectric properties.
  • Optical sensors: Utilize the absorption or reflection of light by water to detect its presence.

Measuring Moisture

Accurate measurement of moisture content is essential for assessing water damage and taking appropriate measures. The best measure of moisture is determined by the specific application and is typically one of the following:

  • Dew point: Measures the temperature at which water vapor in the air condenses into liquid.
  • Relative humidity: Indicates the amount of water vapor in the air compared to its maximum capacity.
  • Water content: Expresses the weight of water present in a material or substance.
