Chandrayaan-3 Mission: Vikram Lander's Unexpected Experiment
In August 2023, following the successful soft landing of the Chandrayaan-3 lander, Vikram, on the Moon, ISRO scientists encountered a unique challenge. The lander had some propellant left, posing a decision-making dilemma.
Dilemma Among Scientists
- Some scientists wanted to utilize the leftover propellant.
- Others preferred not to conduct further experiments as the mission's primary goal was already achieved.
Decision to Conduct a "Hop" Experiment
- ISRO decided to conduct an unplanned "hop" experiment.
- The Vikram lander rose 40 cm and landed 30-40 cm away from its original position.
Outcome and Future Implications
- The engines were reignited in September 2023, successfully executing the hop.
- This demonstrated ISRO's capability to lift the lander, a crucial step for future lunar missions with return journeys.
- The successful execution was unexpected as it was not part of the original mission objectives.
