Implicit sub-parts
  • Identify 'Soft Landing' as the primary missed objective of Chandrayaan-2.
  • Categorize the propulsion module, lander module, and rover as distinct subsystems.
  • Differentiate the role of VSSC (Thiruvananthapuram) from SDSC (Sriharikota) regarding the 'Virtual' aspect of the launch.
  • Briefly link the technological leap from Chandrayaan-2 failures to Chandrayaan-3 success.
Common pitfalls
  • Spending too much space on the history of ISRO or Chandrayaan-1 instead of focusing on the specific 'task' missed (Soft Landing).
  • Confusing the Vikram lander and Pragyan rover as a single unit rather than distinct subsystems.
  • Failing to explain the 'Virtual' nature of the VLCC, mistakenly suggesting the physical launch happened at VSSC.
  • Providing an exhaustive list of all ISRO achievements instead of sticking to the four specific countries that achieved soft landing.

Marks allocation hint

Allocate 2-3 marks for identifying the soft landing and the 4-country list. Dedicate 6 marks to the detailed introduction of the Propulsion, Lander, and Rover subsystems. Reserve the final 6 marks for a technical explanation of the VLCC's remote monitoring and system-check capabilities, ensuring the 250-word limit is balanced between description and technical analysis.
