19. The 2013 rocket launch that made Mangalyaan a reality as India entered Mars’ orbit on the 1st attempt.

The Mangalyaan mission cost India only 11% of what it cost NASA to enter Mars. And what’s more, we did it on the first attempt.

20. A little girl offers Anna Hazare some lemon water to break his fast-unto-death after 97 hours as the government agreed to pass the Jan Lokpal Bill in April, 2011.

There have been many more instances in the history of this great nation of ours. But capturing them all on camera or film was perhaps not possible. I’m sure more such events are still to happen and more pictures are yet to be clicked. But these images certainly bring into perspective the power of a photograph and the story it can narrate.
