ISRO Sets Its Sights on the Moon Again with Chandrayaan-3: Aiming for Lunar Exploration and Soft Landing

First impressions

The Indian Space Research Organisation (ISRO) is gearing up for an ambitious lunar mission, Chandrayaan-3, as it aims to achieve a successful soft landing on the Moon. Building upon the lessons learned from the previous Chandrayaan-2 mission, which provided valuable data despite the landing setback, ISRO is venturing back to the Moon on July 14th in its pursuit of scientific exploration.

Chandrayaan-3: A Second Attempt at Lunar Landing

Chandrayaan-3 serves as a follow-up to the Chandrayaan-2 mission of 2019, which, while successful in gathering crucial insights about the Moon, fell short of its primary objective to achieve a soft landing. However, it's worth mentioning that the earlier Chandrayaan-1 mission in 2008 was a remarkable success and revealed evidence of water molecules on the lunar surface. With Chandrayaan-3, ISRO aims to accomplish what its predecessor couldn't—land on the Moon's surface.

“In the face of setbacks, ISRO's Chandrayaan-3 mission symbolizes the indomitable human spirit, the pursuit of knowledge, and the unwavering determination to explore the mysteries of the Moon, inspiring us all to reach for the stars.”

Mission Details and Objectives

Chandrayaan-3 comprises a lander and a rover, both equipped with payloads designed to facilitate experiments and research on the lunar terrain. These components will be housed within a spacecraft launched aboard the ISRO's three-stage medium-lift rocket, Launch Vehicle Mark-III (LVM3). The liftoff is scheduled from SDSC SHAR in Sriharikota, Andhra Pradesh.

The Path to Lunar Landing

Once the rocket lifts off and reaches a specified orbit above Earth, the Chandrayaan-3 spacecraft will separate from LVM3's C25 upper stage and commence its journey towards the Moon. The spacecraft is equipped with propulsion mechanisms that will enable it to enter a lunar orbit as close as 100 km from the Moon's surface. Subsequently, the lander and rover will detach from the propulsion system and attempt a soft landing on the lunar surface.

Lander and Rover Capabilities

The lander possesses advanced technologies, including altimeters, velocimeters, inertial measurement packages, propulsion systems, navigation and guidance control, hazard detection and avoidance mechanisms, as well as a landing leg mechanism. Once the lander has successfully touched down, the rover will be deployed to conduct chemical analysis of the lunar surface.

The Significance of Lunar Exploration

ISRO's interest in lunar exploration stems from the Moon's invaluable connection to Earth's early history. The Moon offers an undisturbed historical record of the inner Solar system environment, making it an intriguing destination for scientific investigation. Furthermore, the discovery of water molecules by Chandrayaan-1 necessitated further exploration to determine the extent of their distribution on the lunar surface, especially in the permanently shadowed regions near the Lunar South Pole.

Conclusion

With the upcoming Chandrayaan-3 mission, ISRO demonstrates its unwavering commitment to lunar exploration and technological advancement. By building upon previous missions and incorporating lessons learned, ISRO strives to achieve a successful soft landing on the Moon, unlocking new insights into our cosmic neighbourhood. As India sets its sights on the lunar surface once again, the anticipation grows for the groundbreaking discoveries and scientific achievements that lie ahead.
