Q. With reference to the payload Chandra’s Surface Thermophysical Experiment (ChaSTE) of Chandrayaan-3, which of the following statement(s) is/are correct?
1.It aimed to study lunar seismic activity.
2.It used a rotation-based deployment mechanism, ensuring smooth penetration into the lunar soil.
Select the correct answer using the codes given below:
Answer: B
Notes:
Explanations –
Statement 1 is incorrect. The ChaSTE payload was designed to measure the temperature profile and thermophysical properties of the lunar regolith (soil), specifically in the top 10 cm of the surface.
Statement 2 is correct. ChaSTE used a rotation-based deployment mechanism to insert its thermal probe into the lunar soil for in-situ temperature measurements. The mechanism allowed the probe to penetrate smoothly to a depth of 10 cm.
