Chandrayaan-3: First Information on Temperature Profile of Lunar Soil

The Indian Space Research Organisation (ISRO) has released the first data from the Chandrayaan-3 mission, which includes measurements of the temperature profile of the lunar soil. The data was collected by the ChaSTE (Chandra’s Surface Thermophysical Experiment) payload, which is mounted on the Vikram lander.

The ChaSTE payload is a probe that can penetrate the lunar soil to a depth of 10 centimeters. It is equipped with 10 temperature sensors that measure the temperature at different depths. The data collected by the ChaSTE payload provides scientists with new insights into the thermal behavior of the lunar soil.

Temperature Variations at Different Depths

The data from the ChaSTE payload shows that the temperature of the lunar soil varies significantly at different depths. At the surface, the temperature can range from -100 degrees Celsius to 100 degrees Celsius, depending on the time of day. At a depth of 10 centimeters, the temperature is much more stable, ranging from -20 degrees Celsius to 20 degrees Celsius.

The reason for the temperature difference between the surface and the subsurface is due to the insulating properties of the lunar soil. The lunar soil is made up of regolith, which is a mixture of dust, rocks, and pebbles. The regolith is very porous, which allows it to trap heat during the day and release it at night.

Implications for Future Exploration

The data from the ChaSTE payload has implications for future exploration of the moon. The stable temperature at depth could make it a good place to store equipment and supplies. The data could also help scientists to design better habitats for astronauts on the moon.

For example, the data could be used to determine the best location for a lunar base. The data could also be used to design a habitat that can effectively regulate the temperature inside.

Future Plans for ChaSTE

The ChaSTE payload is still collecting data, and scientists are eager to learn more about the thermal behavior of the lunar soil. The payload is expected to continue operating for at least one year.

During this time, scientists will continue to analyze the data and publish their findings in scientific journals. The data from the ChaSTE payload is expected to be a valuable resource for future lunar exploration missions.


The first data from the Chandrayaan-3 mission has provided scientists with new insights into the thermal behavior of the lunar soil. The data is helping scientists to better understand the moon’s environment and to plan for future exploration.

The Chandrayaan-3 mission is a major milestone in India’s space program, and it is expected to continue to yield significant scientific results for many years to come.
