Project Description:
Our team aims to create a solution which will allow for testing of water activity in low gravity environments, a key measure in determining evidence of extraterrestrial life. Water activity is defined as the amount of water in a material that is able to react with or attach itself to another material. Generally, the existing models of water activity meters are designed with a humidity sensor at the top of the water chamber. The evaporated water vapor rises and the humidity sensor provides a measurement of the water activity from the provided sample of brine. However, in a low gravity environment the evaporated water vapor does not stay separate from the liquid water and the humidity sensor is not able to take an accurate measurement.
