Q. With reference to the Chandrayaan-3 Mission, consider the following statements:
1.Chandrayaan-3 incorporates additional navigational and guidance instruments to continuously monitor the speed of the lander and making any required corrections.
2.The landing area of Chandrayaan-3 has been expanded.
3.A success-based design model was adopted by ISRO for Chandrayaan-3.
Which of the statements given above are correct?
Explanation –
Statements 1 and 2 are correct. Chandrayaan-3 incorporates additional navigational and guidance instruments to continuously monitor the speed of the lander and making any required corrections. The landing area has been expanded. Instead of trying to reach a specific 500m x 500m patch for landing as targeted by Chandrayaan-2, the current mission has been given instructions to land safely anywhere in a 4km x 2.4km area.
Statement 3 is incorrect. ISRO adopted a “failure-based design” for Chandrayaan-3 instead of a “success-based design” used in Chandrayaan-2. It means that ISRO’s focus during the Chandrayaan-3 mission was on identifying potential failure points and implementing safeguards to ensure a successful landing.
