Chandrayaan-3: Revisiting the Moon with Improved Technology
India is once again making headlines in the world of space exploration with the launch of Chandrayaan-3, the third Lunar exploration mission of the Indian Space Research Organisation (ISRO). It will revisit the Moon with improved technology compared to its predecessors, Chandrayaan-1 and Chandrayaan-2. In this article, we will explore the advancements in technology and the specific improvements and upgrades in Chandrayaan-3.
Advancements in Technology Compared to Previous Chandrayaan Missions
Chandrayaan-3 is not the first lunar mission undertaken by ISRO. Chandrayaan-1, launched in 2008, discovered water on the Moon and mapped its surface in detail. Chandrayaan-2, which took off in 2019, aimed to make India the fourth country to carry out a soft landing on the lunar surface. While the mission was ultimately not successful due to technical difficulties, it still provided valuable information and insights.
Chandrayaan-3 builds on the achievements of its predecessors and is expected to be an improvement in several aspects. One of them is the instrumentation on board. Chandrayaan-3 will carry fewer payloads than its predecessor, giving more room for fuel and facilitating a safer landing. Additionally, the lander will also carry a seismometer, which will help study the Moon’s internal structure and geology. This is a significant upgrade compared to Chandrayaan-2, which only had a seismometer on its orbiter.
Another significant improvement is the use of Artificial Intelligence (AI) in the mission. ISRO is collaborating with the Indian Institute of Technology (IIT) and the Centre for Development of Advanced Computing (C-DAC) to introduce AI-based systems that will help reduce the risk of errors and ensure accurate landing. With the help of AI, the mission will be more efficient and robust.
Specific Improvements and Upgrades in Chandrayaan-3
Chandrayaan-3 will use several upgraded systems and technologies to ensure success. It will have a lunar terrain mapping camera that will help capture images of the landing site in detail. The camera will provide high-resolution images of the landing site and help identify potential hazards.
Another significant upgrade is the use of a new propulsion system. The spacecraft will use a propulsion system that is more efficient and allows greater control of its movement. This is particularly important during the descent phase, where the lander will have to avoid obstacles to make a safe landing.
The lander’s communication system has also been improved. Chandrayaan-3 will use an X-band radio frequency (RF) system, which is a more reliable and secure system compared to the S-band used in Chandrayaan-2. This will ensure better and more stable communication between the lander and the ground station.
Chandrayaan-3 marks yet another landmark achievement for Indian space exploration. The mission not only builds on the successes of its predecessors but also introduces new technology and upgrades. The use of AI and a seismometer on the lander demonstrates India’s commitment to innovation and scientific advancement. With its upgraded instrumentation, propulsion system, and communication system, Chandrayaan-3 is expected to be a more efficient, robust, and safer mission.
As we continue to make progress in space exploration, it is also important to acknowledge and appreciate the larger implications of these missions. Space exploration has the potential to inspire future generations, advance scientific research, and contribute to technological progress. With Chandrayaan-3, India is once again demonstrating its capability and commitment to space exploration, and inspiring a whole new generation of scientists and engineers.
