Fool-proof Chandrayaan-3 landing on moon? Check what ISRO has done to the spacecraft

The design of the Chandrayaan-3 spacecraft is focused on what all can fail and how to ensure it does not affect things in any way to ensure a successful landing.

Chandrayaan-3
Chandrayaan-3 is 10 days away from its final touchdown and the ISRO scientists are showing full confidence in the spacecraft's ability to ace the moon landing. Why? Because everything has been made fool-proof. According to ISRO, this time they have opted for a "failure-based design" to ensure the successful landing of the rover on the moon even if some things go wrong.   This time the the space agency ISRO opted for a failure-based design in Chandrayaan-3, focused on what all can fail and how to protect it and ensure a successful landing.

Failure based design: For Chandrayaan- 3 ISRO focused on things that can go wrong. So, instead of a success-based design in Chandrayaan-2, ISRO did a failure-based design in Chandrayaan-3. What all can fail, and how to protect it. This is the approach ISRO has taken. (PTI)

Landing area expansion:  The area of landing of the spacecraft has been expanded from 500m x 500m to four km by 2.5 km. According to  (ISRO) Chairman S Somanath "It can land anywhere, so it doesn't limit you to target a specific point. It will target a specific point only in nominal conditions. So, if the performance is poor, it can land anywhere within that area." (ISRO)

More fuel and Additional solar panels: Chandrayaan-3 also has more fuel so it has more capability to travel or handle dispersion or move to an alternate landing site, as revealed by the ISRO Chairman. The Vikram Lander now has additional solar panels on other surfaces to ensure that it generates power no matter how it lands. (ISRO)

Vibration testing and test bed stimulation: The spacecraft was also tested for the ability to withstand vibrations by flying it over different terrains using a helicopter. ISRO did new test beds for simulation, which was not there last time. This was done to look at all the failure scenarios. (ISRO)
