An unmanned spacecraft India launched last month began orbiting the moon Tuesday as it approaches the far side to study previously discovered water deposits.
The Indian Space Research Organization said it successfully maneuvered Chandrayaan, the Sanskrit word for "moon craft," into lunar orbit, nearly a month after it left Earth. The mission is led by two female scientists.
Chandrayaan will continue circling the moon in a tighter orbit until reaching a distance of about 100 kilometers (62 miles) from the moon's surface.
The lander will then separate from the orbiter and use rocket fuel to brake as it attempts India's first moon landing on a relatively flat surface between two craters in the south polar region on Sept. 7.
The success rate of landing on the moon is only 37%, ISRO chairman Dr. K. Sivan said in a news conference. When the semi-autonomous lander decides to land on its own, "it'll be a mix of feeling, of happiness and tension and more anxiety," Sivan said.
A rover will study permanently shadowed craters that are thought to contain 100 million tons of water, deposits that were confirmed by a previous Indian moon mission.
Scientists say water and mineral deposits could make the moon a good pit stop for further space travel.
