Main payload of this mission is India's Cartosat-2 series earth observation satellite. The launch will be carried out from the spaceport at Sriharikota and PSLV-C40 will be used for the launch. The mission consists of 28 nano satellites from other countries, one micro and one nano satellite, and one Cartosat satellite from India.
