What is the primary objective of the Chandra's Surface Thermophysical Experiment (ChaSTE), 2025, payload?

Correct option is A

S. Ans. (a)

Sol.

The primary objective of the Chandra's Surface Thermophysical Experiment (ChaSTE) payload is to measure the vertical temperature profile of the lunar regolith. This experiment will provide detailed data on the thermal behavior of the lunar surface, focusing on how temperature varies with depth. This information is critical for understanding the thermal environment of the Moon and plays a significant role in future lunar exploration, including the planning of human missions. ChaSTE will specifically study the temperature changes within the first few centimeters of the Moon's surface and how these fluctuations vary based on the Moon's day-night cycle.

Information Booster:

•                    ChaSTE will help scientists understand the Moon's thermal inertia, which affects the surface and subsurface temperatures.

•                    The data from ChaSTE will be instrumental for designing lunar habitat systems for astronauts, ensuring proper temperature regulation.

•                    The Moon’s regolith undergoes significant temperature shifts between the lunar day and night, which can affect future lunar activities.

•                    Understanding temperature variations on the Moon is also crucial for locating potential water ice deposits at the lunar poles.

•                    This experiment is part of India's Chandrayaan-3 mission, demonstrating the capability to conduct advanced science experiments on the lunar surface.

•                    It will also aid in better understanding the behavior of the regolith in extreme conditions, such as prolonged sunlight and darkness.
