according to the Chinese Xinhua press agency an Indian Mars probe may be launched in 2013 or 2015, after Chandrayaan-2

Emily Lakdawalla has another post up on this. Key grafs:
QUOTE Meanwhile, in India, the Deccan Herald reports that the integration of the Mars Orbiter Mission's Polar Satellite Launch Vehicle (PSLV) has begun. At the same time, payload integration is proceeding: all five science instruments are now with the spacecraft in Bangalore. The completed spacecraft will be delivered to India's launch facility in Sriharikota in mid-August for its November launch. That seems like a mighty short time for payload integration. On the other hand, the payload isn't really the point on this mission; India's first deep space operations is the point... The original plan had been to launch the Mars mission on India's next-generation heavy-lift launch vehicle, the Geosynchronous Satellite Launch Vehicle (GSLV), but delays and one launch disaster have meant that the GSLV has still not yet had a successful flight. India had to choose between delaying to 2016 or launching on the much smaller PSLV. The PSLV cannot send a spacecraft directly on an interplanetary trajectory; it will launch a downsized Mars Orbiter Mission, carrying a 15-kilogram science payload, into Earth orbit, and an upper stage will widen the spacecraft's orbit through multiple boosts into ever-larger ellipses until finally injecting it toward Mars a month later. Once at Mars, the same procedure will operate in reverse, but mass limitations will prevent the spacecraft from carrying enough fuel to bring it down into a low orbit. Instead, it will be in an elliptical orbit with a distant periapsis. |
