Chandrayaan-3's failure-based design: An ISRO update on India's moon mission

S Somanath, the head of the Indian Space Research Organisation (ISRO), claimed on Monday that Chandrayaan-3 was designed using a failure-based methodology.

"...In a summary, it is easy to say that Chandrayaan-2 had a very restricted capacity for handling parameter variation or dispersion. So this time, all we did was simply make it bigger. Think about the potential pitfalls. With Chandrayaan-3, we are therefore using a failure-based design approach rather than the success-based approach used in Chandrayaan-2. This is the strategy we've used, he told ANI. "What all may go wrong and how to defend it.

At 2.35 p.m. on July 14, the Chandrayaan-3 mission will lift off, and on August 23 or 24, a soft landing is anticipated on the lunar surface. The purpose of Chandrayaan-3 is to demonstrate the capabilities 

On July 14 at 2.35 p.m., the Chandrayaan-3 mission will take off, and on August 23 or 24, it is planned to soft-land on the moon. The Chandrayaan-3 mission is a follow-up to Chandrayaan-2 and aims to demonstrate the possibility of safe moon landing and wandering.

Launch Vehicle Mark-III, a hybrid of a rocket, lander, and rover, will lift off with the Chandrayaan-3 mission.

The launch of the LVM3-M4/Chandrayaan-3 mission will now take place on July 14, 2023, at 2:35 p.m. IST from the SDSC in Sriharikota, according to an ISRO tweet.

The Chandrayaan-3 mission features scientific equipment to investigate the elemental composition, surface plasma environment, and lunar seismicity's thermo-physical characteristics.

The lander will be able to soft land at a chosen location on the moon and release the rover, which will do in-situ chemical analysis of the lunar surface as it is moving.

The public has been invited by ISRO to see the Chandrayaan-3 launch from the launch view gallery in Sriharikota.
