India is counting down to its maiden voyage to Mars later today with its unmanned orbiter Mangalyaan, aka Mars Orbiter Mission.
It will take 11 months for the aircraft to reach the Red Planet, where it will conduct "meaningful scientific experiments" according to K Radhakrishnan, chair of the Indian Space Research Organisation.
Among the Mars Orbiter Mission's ambitious goals is a search for methane in the Martian atmosphere. On Earth, the chemical is strongly tied to life.
