The Indian Space Research Organisation (Isro) is gearing up to land the Chandrayaan-3 mission on the Moon, and former Isro chief K Sivan is confident Vikram Lander will touch the lunar surface.

In an exclusive interview with India Today TV, Sivan expressed unwavering confidence that Chandrayaan-3 will successfully land on the lunar surface despite the setbacks encountered during the previous mission, Chandrayaan-2.

The scientist who led Chandrayaan-2 mission in 2019 said that the failures of that mission should not deter expectations for Chandrayaan-3. He pointed out that the two missions are entirely distinct, each equipped with its own systems and sensors. Sivan reassured that the Chandrayaan-3 systems have been operating smoothly without any issues, and he expects a successful landing on the Moon’s surface.


Sivan shed light on the complexity of the lunar landing process, describing the challenges of reducing the spacecraft’s velocity from approximately two kilometres per second to zero within a precise 15-minute window. He emphasised that this controlled reduction in velocity is critical to avoiding a hard landing, and the Chandrayaan-3 mission has been meticulously designed to tackle these challenges.

Talking about the technical difficulties encountered during Chandrayaan-2, Sivan stated that the errors have been rectified in Chandrayaan-3. “Design margins have been improved, and redundancies have been incorporated into the system to ensure mission success,” Sivan said.

The former Isro chief also commended the resilience of Isro scientists, highlighting their ability to quickly bounce back from disappointments. He stated that Isro’s robustness is reflected in its ability to swiftly analyse mission data, identify issues, and implement corrective measures.

Regarding the challenging terrain near the lunar south pole, Sivan asserted that the Chandrayaan-3 rover is well-equipped to handle adverse conditions, including rough terrain and rocky surfaces.

While acknowledging the complexity and unknown variables of space missions, he emphasised that Isro was doing everything humanly possible to ensure Chandrayaan-3’s success. However, he also acknowledged that there are always “unknown unknowns” in space exploration, and hence, they approach the mission with a sense of anticipation and anxiety.

India’s Chandrayaan-3 mission is set to prove the country’s capabilities in lunar exploration once again.

The mission’s success will not only boost India’s reputation in space science but also contribute valuable data to the global understanding of our celestial neighbour, the Moon.

Chandrayaan-3 will begin its landing approach on August 23 at 5:45 pm and the landing is expected at 6:08 pm.
