Chandrayaan, meaning "Moon vehicle" in Sanskrit, is the name of India's ambitious lunar exploration program. It consists of two successful missions to date: Chandrayaan-1 and Chandrayaan-3.

Chandrayaan-1 (2008): Launched in 2008, Chandrayaan-1 was India's first lunar mission. It carried a probe that successfully orbited the moon and made significant scientific discoveries, including the confirmation of water ice on the lunar surface. While the mission's orbiter exceeded its planned lifespan, contact was eventually lost in 2009.

Chandrayaan-3 (2023): This follow-up mission, launched in July 2023, aimed to build on the success of Chandrayaan-1 by attempting a soft landing on the lunar surface. Chandrayaan-3 consisted of a lander and a rover designed to analyze the lunar soil. It achieved a historic feat by becoming the first spacecraft to soft-land on the Moon's south pole in August 2023. This landing made India the fourth country to achieve a soft lunar landing, following the Soviet Union, the United States, and China. While the mission on the lunar surface was cut short due to the harsh lunar night temperatures, Chandrayaan-3 successfully demonstrated India's advanced space capabilities.

The Chandrayaan program is a significant achievement for India's space agency, ISRO (Indian Space Research Organisation). It has not only yielded valuable scientific data but also inspired future generations of scientists and engineers. With the success of Chandrayaan-3, India has positioned itself as a major player in lunar exploration, and we can surely expect more exciting missions from them in the future.
