After Russia's Luna-25 crash, all eyes are on successful landing of Chandrayaan-3 which is in the final process of landing. Notably, there are some major challenges for the Indian spacecraft ahead of its landing on the moon.

Speed And Direction

According to ISRO, the most important thing in the landing of Vikram Lander is to get the spacecraft from a horizontal to a vertical position. Currently, it is travelling around 1.68 km per second, which should be reduced to at least 2 meters per second. If the speed is high, then it may cause harm to Chandrayaan-3.

Identifying The Right Landing Site

It is very important to identify the right landing site for Chandrayaan-3. Last time the landing site for Chandrayaan 2 was kept at 500 m x 500 m, but this time it has been increased to 2.5 km x 4 km so that Vikram Lander does not face any problem.

Maintain Communication

Another major challenge before Chandrayaan's Vikram Lander and Pragyan Rover is to maintain contact with ISRO's control center. Luna-25 lost contact at the last moment. According to ISRO, the propulsion module of Chandrayaan is working well. Apart from this, the orbiter of Chandrayaan-2 is also active. It will also decode Vikram's message and send it to the command center.

What Was The Reason For Luna's Crash?

According to the Russian Space Agency, Luna-25 had gone into an unexpected orbit. It released the thrust to send it into orbit for pre-landing, but then an emergency situation arose at the automatic station due to which the spacecraft crashed.

Will Land Even If The Engine Fails

According to ISRO Chief Somnath, this time Chandrayaan has been designed in such a way that even if everything fails, it will land. Even if the sensors fail or the engine fails, Vikram will land on the lunar surface, just its propulsion system should work well.
