NEW DELHI: Indians were elated for becoming the first country in the world to enter the Martian orbit in its maiden attempt and many took to Facebook and Twitter saying "mission accomplished".

Happy and proud Indians, including many living abroad, took to the social networking sites to express their happiness and share the moment of pride.

Indians living abroad were all praise for the national broadcaster Doordarshan's live coverage of the event.

Suyash Chopra, a resident of the U.S., tweeted: "Excellent coverage. You have been always BEST. Hats off to you guys. I watched Mars Mission LIVE from USA, courtesy DD (Doordarshan)."

India's Mars Orbiter Mission (MOM) sped over 650 million km through deep space for over nine months to reach the Red Planet's orbit, making India join the elite club of the U.S., Europe and Russia, which reached Mars after initial failures.

The 450-crore ($70 million) ambitious mission was launched Nov 5, 2013, on board a polar rocket from spaceport Sriharikota off Bay of Bengal, about 80 km northeast of Chennai.
