Suggestions for Chandrayaan-3
Along with Chandrayaan-3 there should be a humanoid robot sent.
The advantage of doing this is that we can carry out human like activities without actually sending any human. It would not require any expensive space suit and would not be affected by harsh conditions on moon.
The disadvantage of such idea is that we (Indians) have not yet developed any such humanoid yet and starting to design one now doesn't promise its completion within Chandrayaan-3's time frame. On the other hand sending one such machine would be far less expensive as compared to sending humans and would be done for the first time.
