Q. With reference to Chandrayan-2 Orbiter, consider the following statements:
1. It has detected presence of potential water ice at the lunar poles.
2. Minor elements like Chromium and Manganese have been detected.
Which of the statements given above is/are incorrect?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: D

Both statements are correct. 

  • Statement 1 is correct: The Dual Frequency Synthetic Aperture Radar has reported detection of potential water ice at the poles as it has been able to distinguish properties of surface roughness from that of water ice. 
  • Statement 2 is correct: The Large Area Soft X-Ray Spectrometer (CLASS) measures the Moon’s X-ray spectrum. This instrument has detected the minor elements chromium and manganese for the first time through remote sensing. Sodium was detected without any ambiguity for the first time.
