Explanation:

Recently, Minister of State for Space has said that the launch of Chandrayaan-3 may now take place somewhere in early 2021.

• Chandrayan-3 will be the third moon mission by ISRO.
• Chandrayaan-3 will be a mission repeat of Chandrayaan-2 and will include a Lander and Rover similar to that of Chandrayaan-2, but will not have an orbiter.
• He also said that Images sent by Chandrayaan-1 show that Moon may be rusting along the poles. The sign of this finding is that even though the surface of the Moon is known to have iron – rich rocks, it is not known for the presence of water and oxygen, which are the two elements needed to interact with iron to create rust.

Hence only statement 1st is correct.
