Chandrayaan-3 is on a quest to the Moon, embarking on a 42-day journey filled with critical phases. The mission has been garnering attention worldwide by focusing on mapping the uncharted frontiers at the much-coveted lunar South Pole and carrying forward the legacy of Chandrayaan-1.
Chandrayaan-1, the inaugural Indian lunar probe under the Chandrayaan program, marked a significant milestone for India’s space exploration efforts. Launched by the Indian Space Research Organisation (ISRO) in October 2008, the mission advanced India’s space capabilities by showcasing indigenous technology for lunar exploration in the southern region.
Lunar South Pole: A Complex and Ambitious Endeavour
But what makes this particular landing near the Lunar South Pole so fascinating when the first landing on the Moon occurred almost 5 decades ago?
This is because the lunar South Pole is characterized by a rougher terrain, with more craters and mountainous regions. This area also undergoes variations in lighting conditions due to the Moon’s tilt and rotation around the Sun. Launching a project to this polar end, instead of much simpler places like the equator or the northern side of the Moon, translates to a journey that demands more fuel and is full of challenges.
Further, establishing a continuous communication link with the spacecraft on the farther side of the Moon with extreme temperature fluctuations at the lunar South Pole poses a severe challenge. In the permanently shadowed region, temperatures drop to extremely low levels, as low as -238 degrees Celsius (-396 degrees Fahrenheit). These extreme temperatures endanger the spacecraft and its equipment, making it vital to design the lander to withstand such conditions.
Despite such obstacles, landing at the Southern Pole is of great scientific interest, a fact that was realized in the findings of Chandrayaan-1 itself. The permanently shadowed areas contain water ice and other volatile compounds, which are potentially critical resources for future lunar exploration and even for supporting human settlements.
Significantly, the Chandrayaan-3 mission holds excellent potential to place ISRO on top of space agencies worldwide. With the ultimate goal of a soft landing near the South Pole of the Moon, the anticipation of this will keep everyone hooked until August 23, 2023.
Chandrayaan-3 – A Strategy-driven Masterpiece
Chandrayaan-3 sets itself apart with its groundbreaking objectives and advanced technology.
Firstly, Chandrayaan-3 aims to demonstrate a safe and gentle landing on the Moon, a pivotal step in paving the way for future manned missions and deep space exploration. The indigenous Lander module (LM) is designed to touch down at a predetermined lunar site expertly. In fact, the mission’s success would make India the fourth country to accomplish a safe landing on Moon after the US, China and Russia.
Secondly, the mission introduces a Rover to roam the lunar landscape, performing in-situ scientific experiments. Equipped with five advanced instruments, the Rover will extensively analyze the physical characteristics of the Moon’s surface, study the atmosphere near the surface and delve into the mysterious tectonic activity occurring beneath the lunar crust. The prospects of discovering lunar secrets have the scientific community and enthusiasts eagerly awaiting the mission’s outcomes.
Lastly, Chandrayaan-3 is a stepping stone for interplanetary missions by developing new technologies required for deep-space exploration. The Propulsion Module (PM) will carry the Lander module to its final lunar orbit and then separate from it.
Potential International Scientific Collaborations
According to Union Science and Technology Minister Dr. Jitendra Singh, Chandrayaan-3 will significantly enhance India’s international collaborations, particularly in the fields of science, technology, innovation and startups.
Both USA’s NASA and India’s ISRO are actively working on a strategic framework for cooperation in human spaceflight, and NASA is currently seeking Indian astronauts. During Prime Minister Narendra Modi’s recent US visit, India signed the Artemis Accords, outlining a shared vision for space exploration. Following this, India and the United States launched a call for collaborative proposals focused on “Critical and Emerging Technology: Quantum Technologies and Artificial Intelligence for Transforming Lives,” further strengthening the partnership between the two nations in these cutting-edge domains.
As the flight continues on its trajectory, the entire nation and the global space community hold their breath in anticipation of the scientific revelations and achievements that await. With ISRO’s determination, Chandrayaan-3 stands as a beacon of innovation, pushing the boundaries of human exploration and fetching the secrets of the Moon like never before.
