Chandra’s Surface Thermophysical Experiment (ChaSTE)

NSSDCA ID: 2023-098A-02

Mission Name: Chandrayaan 3


Chandra’s Surface Thermophysical Experiment (ChaSTE), part of the Chandrayaan 3 lander payload, has the primary objectives of measuring lunar surface temperatures, thermal conductivity, and the temperature gradient t a depth of 10 cm. The instrument consists of a 10 cm long probe which is inserted into the lunar regolith. A harness connects the probe to the electronics inside the lander. The probe contains thermal sensors, and is mounted on the side of the lander and inserted into the regolith by a motorized device. The instrument was designed by the Physical Research Lab and the Space Physics Lab.
