India has accomplished a remarkable feat in space exploration as the Chandrayaan-3 spacecraft successfully landed on the surface of the moon. The lander and rover landed at 12:34 UTC (8:34 EST) on Wednesday, August 23, making India the fourth country to make a soft landing on the Moon, following in the footsteps of the Soviet Union, the United States and China.
The significance of this achievement lies in the fact that Chandrayaan-3 is the first mission to land at the South Pole of the Moon, that is, almost 70 degrees south latitude. The area is of great interest to space agencies due to the presence of permanently shadowed craters where water ice has been found. This discovery opens up possibilities for future research and resource utilization.
The NASA-led Artemis 3 mission aims to land a man on the south pole of the moon in the coming years. However, India has now taken the lead in exploring this intriguing region. The moon’s slight tilt leads to the formation of cold traps at the poles where no sunlight reaches. About 60% of these cold traps are located beyond 80 degrees latitude at the South Pole.
A lunar landing remains an unusual achievement, despite several successful missions in the past. It is a risky endeavor, as the emergency landing of Russia’s Luna-25 spacecraft demonstrated. Israel, a partnership between the United Arab Emirates and Japan, and India’s Chandrayaan-2 spacecraft have also faced problems safely reaching the lunar surface. The Vikram rover, part of the Chandrayaan-2 rover, had software and speed problems during its descent, leading to an emergency landing.
Despite these obstacles, the Chandrayaan-2 orbiter continued to make valuable scientific observations around the Moon. It has taken some of the highest resolution images of the lunar surface to date and was instrumental in the success of the Chandrayaan-3 mission.
Although the landing itself was a milestone, there are still many challenges ahead. The Moon’s South Pole presents a harsher environment compared to other regions of the Moon. The terrain is rugged, access to sunlight is limited, and temperatures can drop to extremely low levels. Nevertheless, the expedition team aims to overcome these obstacles.
The next phase of the mission is planned to demonstrate the rover’s ability to travel on the lunar surface and conduct experiments with the soil. Among the main objectives are to analyze the composition of the lunar surface, determine the amount of ice in the soil, and better understand the Moon’s evolving atmosphere.
Experts are optimistic about the mission’s prospects and believe it will exceed its original goals. The lander and rover are expected to operate for at least 14 Earth days, equivalent to a full lunar day, and the orbiter is expected to continue scientific observations for at least six months.
This historic achievement by India not only demonstrates the country’s technological prowess, but also makes a significant contribution to our understanding of the Moon and paves the way for future lunar exploration.
