India's 1,350kg (2,976lb) robotic satellite which is undertaking the 10-month-long, over 200-million-kilometre journey to Mars is equipped with five instruments.
They include a sensor to track methane or marsh gas - a possible sign of life - on Mars, a colour camera for taking pictures, and a thermal imaging spectrometer to map the surface and mineral wealth of the planet. The mission will also analyse the thin Martian atmosphere.
