The spacecraft would be carrying 11 payloads (scientific instruments) and weigh about 1,380 kg at the time of its launch, according to reports. Chandrayaan-1 satellite would orbit the Moon at an altitude of 100 km mapping the topography and the mineralogical content of the lunar soil.
Chandrayaan-1 would also carry a Moon Impact Probe payload for demonstrating the technology needed towards landing on the Moon's surface. India believes the Rs 386-crore lunar mission is a step towards its quest for exploration of outer space and inter-planetary missions.
Chandrayaan-1 is the first spacecraft mission of ISRO beyond Earth's orbit. It would be followed by Chandrayaan-2 which features a lander and a rover. India and Russia would jointly participate in this project. However, there might be a provision to accommodate payloads from other space agencies as happened in Chandrayaan-1.
The objectives set with the Chandrayaan-1 are
--to expand scientific knowledge about the moon
--to upgrade India's technological capability
--to provide challenging opportunities for planetary research to the younger generation of Indian scientists.
