The Indian Space Research Organization is working on the objectives after the Chandrayaan 3 successful landing. Measuring the Moon surface temperature is one of the major objectives of ISRO’s Moon mission. The lander module contains a rover that is equipped with advanced sensors and technologies including the ChaSTE payload (Chandra’s Surface Thermophysical Experiment). Moon Surface Temperature is measured through ChaSTE payload (Chandra’s Surface Thermophysical Experiment). It is the lander payload.
Chandrayaan-3 landed on 23rd August 2023 with a propulsion module and a lander module. The lander and the rover contain 5 payloads that are designed to measure the thermal conductivity and temperature, seismicity around the landing surface, plasma density, lunar laser ranging studies, elemental composition, as well as the vicinity of the landing surface of the moon.

What is the Moon Surface Temperature?
As per the recent update conveyed by the ISRO (Indian Space Research Organization), Chandrayaan-3 recorded a considerable temperature variation in the moon’s surface. The temperature recorded is as high as 70 degrees and as low as -10 degrees.
ISRO scientist BH Darukesha said the team estimated that the temperature of the landing site of the moon where Chandrayaan-3 is targeted should be at 20-30 degrees centigrade. However, after the activation of the ChaSTE payload and its experiments, the reading revealed that the moon surface temperature is 70 degrees centigrade, which is much higher than expected.
Moon Surface Temperature Variation
The surface of the earth doesn’t show notable variations, there is only a 2-3 degree Celsius difference in temperature of the earth’s surface and below the earth’s surface.
The first observation from the ChaSTE payload possessing the temperature probe with controlled penetration reveals that, at a depth of -80 mm beneath the moon’s surface, the temperature drops to minus 10 degrees Celsius.
The temperature on the ground is 50 degrees Celsius. However, the moon’s surface temperature increases over 60 degrees Celsius at 20 mm height. Thus, there is almost a 50-degree centigrade variation.
The average temperature on the surface of the moon is very hot during the day and extremely cold during the night at the equator. It ranges between 106 degrees Celsius during the day and minus 183 degrees Celsius during the night.
Astronauts wear special space suits that constitute reflective surfaces, a combination of insulation, and ice sublimation. All these equipment can regulate the temperature.
The temperature on the surface of the moon ranges between 110 degrees Celsius during the day to minus 173 degrees Celsius at night. Chandrayaan-3 has recorded a temperature of 50 degrees Celcius at the lunar surface.
