ISRO Mars Orbiter Mission: Spacecraft successfully enters Martian Orbit
I remember when in 2012, the then PM of India had declared this project.  The entire internet community came together to deride this, saying it's not possible in a couple of years and that India had better feed its hungry etc.I am a very proud Indian today.  This achievement, like other by humanity (LHC in particular), will encourage me to push myself towards greatness.
