In a momentous stride for the Chandrayaan-3 mission, a pivotal juncture was reached on Thursday, wherein the lander module named ‘Vikram’ and the accompanying propulsion module accomplished a seamless separation. This significant achievement advances the mission’s trajectory, propelling it closer to the Moon. The upcoming focal point now centers on the impending critical landing on the lunar expanse, a mere seven days away, precisely on August 23.
Culminating a series of meticulously orchestrated maneuvers, the propulsion module of the Chandrayaan-3 mission achieved a significant milestone on August 16 by successfully executing its fifth and ultimate maneuver within the lunar orbit. This accomplished feat follows a sequence of intricate orbital adjustments, with three consecutive orbit reduction maneuvers conducted on August 6, 9, and 14, all of which were strategically devised to progressively draw the spacecraft into closer proximity to the lunar terrain.
The lander module is slated to embark upon a series of designated tasks within the lunar orbit, a strategic trajectory it will follow until it culminates in a graceful and controlled descent, resulting in a soft landing upon the lunar surface. This carefully orchestrated sequence of operations underscores the meticulous planning and precision that characterize the Chandrayaan-3 mission, a testament to the advanced capabilities of the Indian Space Research Organisation (ISRO).
The propulsion module of Chandrayaan-3 has assumed a pivotal role, playing a multifaceted role in the mission’s trajectory. This integral component has not only propelled the lander and rover towards the Moon, bringing them into closer proximity, but it has also assumed the role of a communication relay satellite, facilitating seamless and crucial communication between the mission and its control center on Earth.
Upon its separation from the lander module, the propulsion module of Chandrayaan-3 will transition into a new and profound phase, leveraging its advanced capabilities for a pioneering mission beyond the confines of our lunar neighbor. Following its instrumental role in positioning the lander module in close proximity to the Moon, the propulsion module is primed for a remarkable task: the search for extraterrestrial life on exoplanets situated beyond the boundaries of our solar system. This endeavor will be achieved through the utilization of the Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload.
According to information provided by the Indian Space Research Organisation (ISRO), the propulsion module is anticipated to persist in its current orbit for an extended duration, potentially spanning months or even years. This extended journey serves as a testament to the propulsion module’s endurance and stability in the demanding environment of space.
The payload, known as the Spectro-polarimetry of Habitable Planet Earth (SHAPE), is poised to undertake a comprehensive spectroscopic examination of Earth’s atmosphere, focusing on the meticulous measurement of polarization fluctuations emanating from terrestrial clouds. The dataset procured through the SHAPE payload’s observations holds the dual promise of advancing the understanding of potentially habitable exoplanets while concurrently enhancing our comprehension of Earth’s atmospheric dynamics.
In a recent development, S Somanath, the esteemed Chairman of the Indian Space Research Organisation (ISRO), provided a notable affirmation regarding the advancement of the Chandrayaan-3 mission. With a sense of assurance, he conveyed that all systems integral to the mission’s success were meticulously operating according to plan. This declaration underscores the meticulous planning, technical proficiency, and coordinated efforts that characterize the Chandrayaan-3 mission.
