India has recently sent a small spacecraft to Mars, as a technology demonstration mission. It has also subsequently successfully demonstrated its much-delayed cryogenic upper stage engine with the launch of its GSLV D5.
Cryogenic propulsion is a prerequisite for India's next generation of rocket, the GSLV-Mark-III. The planned payload capacity of the Mk-3 is much higher than the PSLV rocket which launched India's Mars Orbiter Mission, giving rise to calls to send a more substantive mission to Mars; this in the form of a lander mission.
Based on the projected launch capacity of the Mk-3 -
- How massive a lander could India send to Mars?
- Would there be adequate margin to accommodate a rover?
