ISRO’s S Somanath assures Chandrayaan-3’s Vikram lander can achieve a successful Moon landing on August 23, even with sensor and engine issues. Resilient design and precautions address challenges for the mission.

Lunar Landing Confidence Despite Failures

ISRO chairman, S Somanath, shared that the lander of India’s Chandrayaan-3 mission, Vikram, is designed to perform a soft landing on the Moon’s surface on August 23, even if certain sensors and two engines malfunction.

Design Resilience for Unforeseen Situations

Speaking during a talk hosted by Disha Bharat, Somanath emphasized the meticulous design of the lander to accommodate potential failures. He stated that even in a scenario where all sensors fail, Vikram will still aim for landing, given the propulsion system functions as intended.

Chandrayaan-3 Mission Progress

Chandrayaan-3 embarked on its journey on July 14 and entered lunar orbit on August 5. The upcoming de-orbiting maneuvers are scheduled for August 9, August 14, and August 16, gradually reducing the orbit to 100 km x 100 km.

Crucial Vertical Landing Process

Somanath discussed the challenge of transitioning the horizontal movement of Vikram to a vertical landing on the lunar surface. The need to shift from horizontal to vertical orientation is key, as shown by past challenges.

Learning from Past Setbacks

Referring to the previous mission’s landing setback, Somanath explained the complexity of converting horizontal to vertical movement. The current efforts are focused on proper fuel consumption, accurate distance calculations, and precise algorithm functioning.

Mitigating Variations in Calculations

The ISRO team has taken steps to ensure a successful landing even in the face of calculation variations. Their preparations encompass scenarios where calculations may not align perfectly.

Confidence Amid Challenges

Somanath’s assurance of Vikram’s landing success reflects ISRO’s commitment to overcome past obstacles and achieve a secure lunar touchdown.
