On 5 June 2017, India performed a full launch test of their GSLV-MK3, putting a test-satellite into geosynchronous transfer orbit. This is a huge step forward for the India Space Research Organisation (ISRO), which could eventually use this rocket for human space travel. For the details on the rocket itself, as well as a rundown of ISRO's history check out this article from the Planetary Society.
