India's space agency the Indian Space Research Organisation (ISRO) today successfully launched the nation's heaviest next-generation rocket named the Geosynchronous Satellite Launch Vehicle (GSLV-Mark III) into space. ISRO confirmed the successful launch on Twitter.

The launch began at 9 am from the Satish Dhawan Space Centre in Sriharikota. It is one of the most important space mission India has undertaken. Here are ten facts about ISRO's latest mission.

According to an IANS report, MYS Prasad, director of the Satish Dhawan Space Centre in Sriharikota said that that "During the countdown, the rocket's liquid fuel engine will be fuelled up and the passive cryogenic engine at the top will be filled with liquid nitrogen for mass simulation.

2) According to this article on NASASpace.com, the GSLV-Mark III and LVM3, is a completely new vehicle marking the third generation for India’s orbital launch systems.

3) The rocket has two active solid and liquid propulsion stages, according to the ISRO website. These are the S 200 and L110. In addition to its there is also the cryogenic engine C 25 X which in a passive state as it is still under development.
