According to the search results, the Indian Space Research Organisation (ISRO) launched the Chandrayaan-3 mission on July 14, 2023, which consisted of a lunar lander named Vikram and a lunar rover named Pragyan. The spacecraft entered lunar orbit on August 5, and the lander touched down near the lunar south pole on August 23, making India the fourth country to successfully land on the Moon, and the first to do so near the lunar south pole. The rover completed its assignments and was put into sleep mode on September 2, along with the lander, which successfully performed a short "hop" and exceeded its mission objectives. The two modules were put in sleep mode for the lunar night, which is equal to around 14 days on Earth. However, ISRO has so far failed to re-establish communication with both the Vikram lander and Pragyan rover, raising concerns about the missions further exploration of the lunar surface. The Indian space agency has said that "no signals have been received" from Vikram and Pragyan, and efforts to establish contact will continue. Former ISRO Chairman AS Kiran Kumar told BBC that chances of the rover and lander awakening are uncertain as the temperature on the Moon can plummet to as low as -200 to -250 degree Celsius during the night, and batteries are not designed to be stored or operate at such extreme temperatures.
