In order to improve our ability to map the surficial geology of Mars and aid in the search for habitable environments and signs of past or present life, the PSF has constructed a large-capacity (~0.8 m3) environment chamber that allows for exposure of samples or instrumentation to Mars-like surface conditions of atmospheric pressure and composition and UV irradiation for extended periods of time. The chamber can be interfaced with various spectrometers. In terms of geological mapping, this facility is being used to examine the stability and spectral behaviour of water-bearing minerals that may be present on Mars.
