Sure of Chandrayaan-3's success: Ex-ISRO boss K Sivan who led Chandrayaan-2 mission; Why India's second Moon mission failed
Chandrayaan-2 encountered a high-velocity landing due to accumulated errors on its sensors. Chandrayaan-3's design focuses on mitigating this concern through improved control mechanisms. Chandrayaan-2 grappled with challenges during the landing process, where engine thrust exceeded expectations. Chandrayaan-3 emphasises precise engine thrust dispersion to prevent error accumulation.
