India's space agency is the first to walk on the moon's south pole. Chandrayaan-3's rover walk means that India has joined America, the former Soviet Union and China’s elite club. The rover is roaming the rocks and craters at 1 cm per second, gathering data and images to send to earth for analysis. It landed on the start of a lunar day, which equals a little over four earth weeks. The lander and rover will use these days of sunlight to charge their batteries. A major goal is to hunt for water. The craters, permanently in shadow, hold ice which could support human habitation on the Moon in future. It could also be used for supplying propellant for spacecraft headed to Mars and other distant destinations. Narendra Modi said India wants to open its space sector to foreign investment as it targets a five-fold increase in its share of the global launch market within the next decade.
