India has a pretty good track record on following through on space commitments, so this all seems achievable to me. It's already landed on the Moon with Chandrayaan-3. I wonder by 2040 will there be anyone in permanent habitation at the International Lunar Research Station? Who knows how many space stations there will be in ten year's time (2035). China will have one, the ISS will have de-orbited, but presumably there will be Western commercial ones too.
