Chandra's Surface Thermophysical Experiment (ChaSTE)

ChaSTE aims at in-situ measurements of thermal conductivity and temperature profile on the lunar surface to derive the vertical temperature gradient up to a depth of 100 mm at the site of landing. This is carried out by means of inserting a probe consisting of thermal sensors in to the lunar regolith using a motor based mechanism. ChaSTE provides thermophysical properties of a igh latitude region on the Moon for the first time. This instrument is being developed jointly by the Physical Research Laboratory(PRL), Ahmedabad and the Space Physics Laboratory(SPL), VSSC, Trivandrum. The flight model for chandrayaan-2 has been delivered in 2017.
