When by 1:27 am on 20 oct 2014 the tail of comet Siding Spring would have flown past closest to Mars ( or to any planet in known history of mankind), only three countries on earth would have their orbiters or rovers on planet Mars directly study the impact of comet dust in such close quarters !! US, India and a conglomeration of countries from Europe !
Isin't it a great achievement giving a great sense of satisfaction to be counted as one of the topmost technologically advanced countries of the world ?
Neighbour's (china) envy, owner's pride !!
