How the moon kicked Chandrayaan-3 propulsion module into a new orbit

In a remarkable display of advanced orbital mechanics and strategic ingenuity, the Chandrayaan-3 Propulsion Module (PM), following its successful deployment of the Vikram lander and Pragyan rover on the Moon's south pole in August 2023, embarked on an extended mission. Initially positioned in a wide Earth-bound orbit that merely grazed the Moon's gravitational sphere of influence, the Indian Space Research Organisation (ISRO) executed a precise maneuver. Between October and November 2023, the PM, leveraging the Moon's gravitational pull, was nudged into a new, wider orbit around Earth, significantly extending its operational life and data collection capabilities.

This unplanned yet highly significant maneuver underscores India's burgeoning capabilities in space exploration and orbital dynamics. It not only showcases ISRO's deep understanding of celestial mechanics but also offers invaluable insights for future deep-space missions, potential strategies for space debris management by repurposing operational satellites, and optimizing fuel consumption. For India, it solidifies its position as a responsible and innovative space power, enhancing its global standing in space diplomacy and technology.

For competitive exams such as UPSC, SSC, Banking, and State PSCs, this event is a crucial current affairs topic. It directly connects to Science & Technology (space exploration, orbital mechanics, indigenous capabilities), International Relations (space diplomacy, global partnerships), and Economy (space sector growth, private participation). Aspirants must understand the technical aspects, the broader implications for India's strategic autonomy, and the economic opportunities in the burgeoning space sector.

India's journey in space exploration, spearheaded by the Indian Space Research Organisation (ISRO), is a testament to perseverance and indigenous innovation. Established in 1969, succeeding the Indian National Committee for Space Research (INCOSPAR) formed in 1962, ISRO’s mandate has been to develop space technology and its application to national development. From the launch of its first satellite, Aryabhata, in 1975, to the recent Chandrayaan-3 success, India has consistently pushed the boundaries of space science.

The Chandrayaan program, specifically, marks India's ambitious foray into lunar exploration. Chandrayaan-1, launched in 2008, was a pathfinder mission that successfully orbited the Moon and confirmed the presence of water molecules on its surface. This was followed by Chandrayaan-2 in 2019, which aimed for a soft landing but unfortunately saw its Vikram lander crash due to a software glitch, though its orbiter continued to provide valuable data. Learning from this experience, Chandrayaan-3 was conceived as a follow-up mission, meticulously designed for a successful soft landing and lunar surface exploration. It was launched on July 14, 2023, using the Launch Vehicle Mark-3 (LVM3-M4) from Satish Dhawan Space Centre, Sriharikota. The Vikram lander successfully touched down on the lunar South Pole on August 23, 2023, making India the fourth nation to achieve a soft landing and the first to reach the lunar South Pole.

The specific maneuver by the Chandrayaan-3 Propulsion Module (PM) is not unprecedented in space history, though its execution for an extended Earth orbit is noteworthy. Gravitational slingshot or gravity assist maneuvers have been utilized by various deep-space missions, such as NASA's Voyager probes and ESA's Rosetta, to gain speed or alter trajectory using the gravitational pull of planets. ISRO itself employed similar principles for its Mars Orbiter Mission (Mangalyaan) in 2013-14, using Earth's gravity to build velocity before heading towards Mars. However, the Chandrayaan-3 PM's maneuver, initiated after its primary mission, demonstrates a sophisticated understanding of orbital mechanics for mission extension and optimization rather than just initial trajectory setting.

The legal and policy framework governing India's space activities has also seen significant evolution. While a dedicated Space Activities Bill has been under consideration for several years, the Government of India promulgated the Indian Space Policy 2023 on April 19, 2023. This policy aims to foster private sector participation across the entire spectrum of space activities, from manufacturing to satellite services, while clearly defining the roles of ISRO, NewSpace India Limited (NSIL), and the Indian National Space Promotion and Authorisation Centre (IN-SPACe). The policy emphasizes strategic autonomy, enabling India to develop and maintain independent capabilities in space. Constitutionally, India's space program aligns with the Directive Principles of State Policy, particularly Article 51, which promotes international peace and security and respect for international law, relevant for adherence to principles of outer space treaty and responsible space behavior.
