He also talks about finding out why water disappeared from the planet and why India is sending a spacecraft to Mars in the first place

When India sent its first Moon mission in 2008-09, many in the developed world scoffed at Chandrayan-1 finding anything significant. But it did, confounding experts by detecting the presence of water on the Moon’s surface, something which the previous NASA missions had failed to detect. Days before the Mars Orbiter Mission (MOM) takes off (it is not called Mangalayan as reports in a section of the media would have us believe) from Andhra Pradesh on November 5, Dr Jitendra Goswami sounded quietly confident that the mission would be successful, even though he took pains to stress that this was also a mission to show the world that India was technologically capable of sending a spacecraft, which could orbit Mars successfully.
