India's space agency said it lost touch with its Vikram lunar lander on Saturday as it made its final approach to the moon's south pole to deploy a rover to search for signs of water. A successful landing would have made India just the fourth country to land a vessel on the lunar surface, and only the third to operate a robotic rover there. The space agency said the lander's descent was normal until 2 kilometers (1.2 miles) from the lunar surface.
