Till when the treatment of AIDS will be possible? It is said that Science and Technology has developed too much then why we are for behind in the field of development? Why haven't we made any spaceships yet?

Research is going on in India and around the world for a cure for AIDS and I am hopeful that in the near future there will be succesful. India today is one of the leading countries in space technology, we are able to design, build and send rockets into space to place satellites into orbit not only for ourselves but also for other countries also.
