The Indian Space Research Organisation (ISRO) successfully launched Chandrayaan-3, a follow-up mission to its earlier lunar landing attempt, marking India's renewed effort to achieve a safe and soft landing on the moon. The spacecraft, consisting of an orbiter, a lander, and a rover, took off from Sriharikota in Odisha on a GSLV Mark 3 (LVM 3) heavy-lift launch vehicle.
If the landing is successful, India will become the fourth country, after the United States, the Soviet Union, and China, to accomplish this extraordinary feat. The mission, named Chandrayaan-3, will embark on a month-long journey, with the anticipated landing scheduled for August 23.
Following a trajectory similar to its predecessor, Chandrayaan-2, the mission will undergo three stages: Earth orbit maneuvers, Trans-lunar injection, and Lunar orbit maneuvers. After these stages are completed, the lander will separate from the propulsion module and approach the moon for a soft landing.
Accurate calculations and synchronization with the moon's orbit around Earth are crucial to ensure the module's precise positioning. Chandrayaan-3 will perform five orbit maneuvers around the Earth, gradually increasing its distance from our planet before setting course for the moon.
Once in lunar orbit, Chandrayaan-3 will conduct four orbits, progressively approaching the moon's surface. It will settle into a circular orbit at an altitude of 100 km x 100 km. Subsequently, the lander will detach from the propulsion module and maneuver to within 30 km of the lunar surface to initiate the soft-landing procedure.
ISRO's Chandrayaan-3 mission aims to demonstrate safe and soft landing capabilities, enable rover mobility on the lunar surface, and conduct in-situ scientific experiments. It will gather data on Earth's polarized light reflection, measure ion and electron density near the moon's surface, monitor temperature near the polar region, search for moonquakes, and explore the lunar crust and mantle structure. Additionally, the mission seeks to enhance our understanding of the Moon's dynamic system.
India's Chandrayaan-3 mission is a significant step towards advancing lunar exploration and scientific knowledge. The nation eagerly awaits the successful outcome of this ambitious endeavor.
