Despite the precautions taken, Chandrayaan-3 might still face unexpected obstacles that could lead to its failure.
While ISRO has taken a failure-based design approach, predicting all possible failure scenarios is an extremely complex task.
Despite efforts to rectify software issues, undetected glitches or errors could still occur- leading to loss of control during critical phases.
Although the landing area has been expanded, landing on a slope or in a rocky area might damage critical components.
If there are inaccuracies or malfunctions in the navigation systems, the spacecraft might not descend to the intended landing site correctly
If there are disruptions in communication between the spacecraft and ground control, it could hinder real-time decision-making and problem-solving.
Extended exposure to the harsh radiation and vacuum of space can have detrimental effects on spacecraft components.
If the spacecraft gets too close to the lunar surface or veers too far away due to gravitational interactions, could lead to unplanned trajectories.
Despite rigorous testing, failures in propulsion systems, landing gear, or other components could still occur due to extreme conditions.
