You must be well aware of the "Incredible India" campaign - with tag "Athithi devo Bava" meaning Guest is equal to god. Treating guests with utmost obedience and respect is what all ancient Indian texts preach. Now some may have reservations whether Indians still cling to it - but this respect to Guests is what attracted many foreign travelers and behind them the invaders and behind them colonizers. Ofcourse thats all a big history. The point here ISRO may soon come up with "Incredible (or Astonishing) Space" campaign  I am not kidding - The Indian Space Research Organisation (ISRO) is known to be taking space tourism very seriously. With the new chief Dr K Radhakrishnan in position, the organization is exploring new strategies and technologies for low cost space tourism.
