Also, ISRO achieved this at very low cost.
Remember that cost of space operations is one of the major hindrances in
exploring more.

Also, the Impact Probe worked. The Impact probe was an all or nothing
attempt and we got all.

The Chandrayaan-2 mission is even more ambitious. I am proud to be
living in this era and
 dreaming of contributing to this great endeavor one day.
