Chandrayaan-3 ChaSTE

  • Chandrayaan-3’s ChaSTE (Chandra’s Surface Thermophysical Experiment) is the first instrument to measure in-situ temperatures near the Moon’s south pole.
  • ChaSTE successfully penetrated lunar soil and deployed a thermal probe, unlike previous missions like ESA’s Philae and NASA’s InSight HP3.
  • It provides crucial data on lunar surface temperatures, supporting evidence of water ice deposits.
  • The thermal probe, integrated into the Vikram lander, has 10 temperature sensors spaced 1 cm apart.
  • It uses a rotation-based deployment mechanism, pushing the probe downwards.
  • ChaSTE reached a depth of 10 cm in the lunar regolith and monitored temperature variations.
  • Final temperature readings confirmed thermal properties essential for lunar exploration.
  • ESA’s Philae lander failed to deploy its temperature probe due to an awkward landing.
  • NASA’s InSight HP3 couldn’t penetrate deep enough due to low friction in Martian sand.
  • Chandrayaan-3 is India’s third lunar mission, aiming for a soft landing near the Moon’s south pole.
  • ChaSTE’s importance lies in providing data on temperature variations beneath the lunar surface, aiding future Moon exploration.
