Explanation: The Indian Space Research Organisation (ISRO) has undertaken several significant missions to explore the Moon, with the Chandrayaan series being a notable part of these efforts. The Chandrayaan missions are designed to study the Moon's surface, composition, and environment, contributing to our understanding of the Moon's history and potential resources.
Chandrayaan-1, launched in 2008, was India's first lunar mission. It orbited the Moon and carried several scientific instruments to map the lunar surface and analyze its composition. One of the key components of Chandrayaan-1 was the Moon Impact Probe (MIP), which was designed to impact the lunar surface. Although the MIP did impact the Moon, it was not a soft landing, and the mission's primary focus was on orbital observations.
Chandrayaan-2, launched in 2019, was a more ambitious mission that aimed to achieve a soft landing on the Moon's south pole. The mission consisted of an orbiter, a lander named Vikram, and a rover named Pragyan. The orbiter successfully entered lunar orbit, but the Vikram lander lost contact with ISRO just before touchdown, resulting in a failed landing attempt. Despite this setback, the orbiter continued to operate and conduct scientific observations from lunar orbit.
Chandrayaan-3, launched in July 2023, was designed to achieve a successful soft landing on the Moon's south pole. The mission included a lander and a rover, both of which were equipped with scientific instruments to study the lunar surface. The lander, named Vikram, and the rover, named Pragyan, successfully landed on the Moon's south pole in August 2023. This mission marked a significant achievement for India, as it was the first successful soft landing on the Moon's south pole by any country.
The south pole of the Moon is of particular interest to scientists because it contains permanently shadowed craters that may harbor water ice. The presence of water ice could be crucial for future human exploration and habitation of the Moon. The Chandrayaan-3 mission aimed to study the lunar south pole's environment and composition, contributing valuable data to our understanding of the Moon's resources and potential for future exploration.
In summary, Chandrayaan-3 is the correct answer as it successfully landed on the Moon's south pole, marking a significant milestone in India's space exploration program. The mission's success highlights the advancements in India's space technology and the country's growing role in lunar exploration.
