Chandrayaan-1 was the first Indian lunar probe under the Chandrayaan program. It was launched by the Indian Space Research Organisation (ISRO) in October 2008, and operated until August 2009. The mission included a lunar orbiter and an impactor. The name Chandrayaan means "Moon-craft" in Sanskrit. Chandrayaan-2 is a follow-up mission which was launched on 22 July 2019. The mission includes a lunar orbiter, a lander named Vikram, and a robotic lunar rover named Pragyan. The rover was designed to move on six wheels on the lunar surface, do on-site chemical analysis, and send the data to the Earth via the Chandrayaan-2 orbiter, which will be orbiting the Moon. The third mission, called Chandrayaan-3, is tentatively scheduled for 2024.
