ChaSTE: Pioneering Lunar Thermophysics with Chandrayaan-3

Introduction to ChaSTE

ChaSTE (Chandra’s Surface Thermophysical Experiment) is a sophisticated instrument located on the Vikram lander of Chandrayaan-3. Its primary role is to measure temperature variations beneath the Moon’s surface, providing invaluable data for future lunar missions.

Function and Purpose

• Measures Lunar Soil Temperature:
  • Records temperature variations at different depths, reaching up to 10 cm below the lunar surface.
  • Contributes to our understanding of the Moon's thermal properties and the mechanisms of heat transfer through the regolith, which is the lunar soil.

Findings from Chandrayaan-3

• Extreme Temperature Variations:
  • The probe has recorded drastic temperature differences, ranging from 82°C on sunlit slopes to -170°C in shaded regions.
  • Results indicate that sloped surfaces and areas at higher latitudes might harbor ice beneath their surfaces.

Importance for Lunar Exploration

• Identifying Water-Ice Reservoirs:
  • ChaSTE plays a crucial role in pinpointing potential water-ice reservoirs, essential for sustaining future lunar missions.
• Data for Designing Habitats:
  • The data collected by ChaSTE is pivotal for designing habitats and instruments tailored for long-term lunar exploration.

“Every measurement we take on the Moon brings us closer to making space a new frontier for human civilization.” The insights gained from ChaSTE will undoubtedly enhance our understanding of the Moon and pave the way for future explorations and potential colonization efforts.
