Chandrayaan 3 Arrival at the Satish Dhawan Space Centre

Chandrayaan 3 Arrival at the Satish Dhawan Space Centre: The Indian Space Research Organization (ISRO) is set to embark on an ambitious lunar mission with the spacecraft named Chandrayaan-3, marking India’s third attempt to land on the moon. In this mission, ISRO aims to achieve controlled soft-landing on the lunar surface and conduct in-situ analysis using a rover. Recently, the spacecraft was transported to the Satish Dhawan Space Centre, the country’s spaceport, after a meticulous journey from the UR Rao Satellite Centre in Bengaluru.

Chandrayaan 3

Space exploration has long been a frontier of human ambition, enabling us to push the boundaries of knowledge and technological advancement. The Indian Space Research Organization (ISRO) has been a key player in the global space community, making significant contributions to space science and technology. With its Chandrayaan-3 mission, ISRO is poised to further expand its achievements in lunar exploration.

Chandrayaan-3: India’s Third Lunar Mission

Chandrayaan-3 is an eagerly anticipated lunar mission that builds upon the successes and lessons learned from its predecessor, Chandrayaan-2. The primary objective of Chandrayaan-3 is to achieve a controlled soft-landing on the lunar surface and conduct in-situ analysis using a rover. By doing so, ISRO aims to gather valuable data and insights about the moon’s composition and its geological evolution.

Arrival at the Satish Dhawan Space Centre

The spacecraft’s journey began at the UR Rao Satellite Centre in Bengaluru, where it was meticulously prepared for transportation. Finally, in the evening hours on Friday, the spacecraft arrived at the Satish Dhawan Space Centre, nestled securely within a specialized truck and under a security blanket. This crucial phase ensures the safe arrival of the spacecraft at the spaceport, where final integration, testing, and fueling will take place before the launch.

The Role of UR Rao Satellite Centre

The UR Rao Satellite Centre plays a pivotal role in India’s space exploration endeavors. It is where the country’s satellites and interplanetary probes are designed, developed, and tested to meet the rigorous demands of space missions. Once the spacecraft is ready for transportation, it embarks on its journey to the Satish Dhawan Space Centre, where further preparations will be conducted before its final launch.

Clean Room Facilities for Safe Transportation

Transporting a spacecraft of such significance and complexity requires utmost care. Owing to the presence of sensitive electronics and space-grade components on-board, the spacecraft is always placed in a clean room, ensuring a controlled environment regardless of the weather outside. Clean rooms maintain constant pressure, temperature, humidity, and have negligible dust particles per cubic meter of air, providing the ideal conditions for safe transportation.

Assembling India’s Heaviest Rocket: LVM3

To accomplish the mission objectives of Chandrayaan-3, India’s heaviest rocket, LVM3, is being prepared at the Satish Dhawan Space Centre. LVM3, formerly known as Geosynchronous Satellite Launch Vehicle Mark 3, will be responsible for launching the Chandrayaan-3 spacecraft into an orbit around the Earth. This crucial step marks the beginning of the spacecraft’s weeks-long journey to the moon.

Tests and Challenges Faced by Chandrayaan-3

The successful launch and operation of a spacecraft require rigorous testing and overcoming various challenges. During the development of Chandrayaan-3, ISRO conducted tests to assess the spacecraft’s ability to handle excessive noise and vibration generated during the rocket’s launch and flight. The spacecraft, securely nestled within the payload fairing, is designed to withstand such harsh conditions and operate normally throughout the journey.

The tests carried out on the integrated spacecraft involved challenging scenarios, considering its composite structure comprising the propulsion module, lander module, and rover module. The vibration and acoustic tests provided valuable insights into the structural integrity and survivability of the spacecraft in the demanding launch environment.

Mission Goals and Objectives

The mission goals of Chandrayaan-3 align with those of its predecessor, Chandrayaan-2, which was launched in 2019. The primary objective remains a safe lunar landing, ensuring that the rover can exit the lander and traverse the lunar surface successfully. The lessons learned from Chandrayaan-2 have been carefully implemented, with various improvements and modifications made to address the challenges faced during the previous mission.

Lessons Learned from Chandrayaan-2

Chandrayaan-2 encountered an obstacle during its controlled lunar landing and crash-landed. This setback prompted ISRO to thoroughly analyze the mission’s shortcomings and take corrective measures. Software changes, improvements in the propulsion system, incorporation of new sensors, and ruggedization to handle unexpected situations and failures were among the key enhancements made to ensure the success of Chandrayaan-3.

The Difference in Payload: Chandrayaan-2 vs. Chandrayaan-3

Unlike Chandrayaan-2, which carried an orbiter, lander, and rover, Chandrayaan-3 will focus solely on a lunar lander, rover, and propulsion module. The Chandrayaan-2 orbiter continues to function effectively, performing imaging and remote sensing tasks from an altitude of 100 kilometers above the lunar surface. This streamlined payload composition allows Chandrayaan-3 to focus on achieving its primary objective of a safe lunar landing and subsequent rover operations.

India’s Chandrayaan-3 mission represents a significant step in the country’s space exploration journey. With careful planning, testing, and improvements based on past experiences, ISRO is poised to achieve a controlled soft-landing on the lunar surface and conduct valuable in-situ analysis. The successful execution of Chandrayaan-3 will not only contribute to our understanding of the moon but also strengthen India’s position as a prominent player in the realm of space exploration.
