Introduction:
Chandrayaan-3 embarks on a pioneering mission – one that aims to achieve what no other mission has accomplished since the Soviet Union’s Luna 24 mission in 1976.
It made a soft landing on the Moon’s enigmatic south pole, an endeavor that comes with groundbreaking implications.
This region, shrouded in mystery, holds the promise of significant discoveries. The potential presence of water ice in this area could revolutionize our understanding of the Moon’s composition and its role in shaping the solar system.
The fact that Chandrayaan-3 is not only India’s third lunar mission but also the first to land in the Moon’s south pole is a testament to India’s unwavering commitment to pushing boundaries.
This mission represents a confluence of technical prowess, scientific curiosity, and visionary ambition.
The Chandrayaan-3 mission is historical for a number of reasons. It is:
- India’s third lunar mission, and the first to attempt a soft landing on the Moon’s south pole.
- The first mission to land on the Moon’s south pole since the Soviet Union’s Luna 24 mission in 1976.
- The first mission to land on the Moon’s south pole since the advent of commercial spaceflight.
- A major step forward for India’s space program, which has made significant progress in recent years.
- A testament to the hard work and dedication of the scientists and engineers at the Indian Space Research Organisation (ISRO).

Chandrayaan Series: India’s Lunar Exploration Endeavor
The Chandrayaan series stands as a testament to India’s growing prowess in space exploration, particularly its lunar missions. The series encompasses Chandrayaan-1, Chandrayaan-2, and the latest addition, Chandrayaan-3, each representing significant milestones in India’s journey to unravel the mysteries of the Moon.
The Chandrayaan programme is a series of Indian lunar space probes. The name Chandrayaan means “mooncraft” in Sanskrit and most other Indian languages.
The first mission in the Chandrayaan programme, Chandrayaan-1, was launched on October 22, 2008. It was a lunar orbiter that carried 11 scientific instruments.
The mission was a major success for ISRO, as it discovered water on the Moon. It also mapped the Moon in infrared, visible, and X-ray light, and used reflected radiation to prospect for various elements, minerals, and ice. The mission ended in August 2009.
The second mission in the Chandrayaan programme, Chandrayaan-2, was launched on July 22, 2019. It was a more ambitious mission that included a lunar orbiter, a lander, and a rover.
The lander, Vikram, was supposed to land on the Moon’s south pole, but it crashed due to a technical problem. The orbiter and the rover, Pragyan, are still in orbit around the Moon and are continuing to collect data.
The third mission in the Chandrayaan programme, Chandrayaan-3, was launched on July 14, 2023. It is a re-attempt to land a lander on the Moon’s south pole. The mission is expected to last for one year.
The father of the Chandrayaan programme is Vikram Sarabhai, the founding father of the Indian Space Research Organisation (ISRO). He was a visionary scientist who believed that space exploration could be used to improve the lives of people on Earth.
He played a key role in the development of the Chandrayaan programme and other Indian space missions.
The Chandrayaan programme is a major milestone in India’s space program. It has made significant contributions to our understanding of the Moon and has helped to put India in the forefront of lunar exploration.
The future missions in the Chandrayaan programme are expected to make even greater discoveries and help us to learn more about our lunar neighbor.
Chandrayaan-1: Crash onto the lunar surface.
On October 22, 2008, the Chandrayaan-1 spacecraft, weighing 590 kg (1,300 pounds), embarked on its mission. A Polar Satellite Launch Vehicle lifted off from the Satish Dhawan Space Centre on Sriharikota Island in Andhra Pradesh state to carry Chandrayaan-1 into space.
The spacecraft deftly maneuvered itself into an elliptical polar orbit around the Moon, capturing detailed data in infrared, visible, and X-ray light.
Once in orbit, the spacecraft was carefully maneuvered into an elliptical polar orbit around the Moon. Its orbit ranged from 504 km (312 miles) at its closest approach to the lunar surface to 7,502 km (4,651 miles) at its farthest point.
After undergoing initial checks, the spacecraft descended to a lower orbit at an altitude of 100 km (60 miles). On November 14, 2008, Chandrayaan-1 deployed a small auxiliary craft named the Moon Impact Probe (MIP).
The primary purpose of the MIP was to assess systems for potential future lunar landings and to gather information about the Moon’s thin atmosphere before its controlled crash onto the lunar surface.
Chandrayaan-2: A Bold Leap Towards Lunar Landing
Building on the success of Chandrayaan-1, India embarked on the Chandrayaan-2 mission, launched on July 22, 2019. This mission comprised an orbiter, a lander named Vikram, and a rover called Pragyan. The orbiter, cruising in a polar orbit around the Moon, promised seven and a half years of fruitful exploration.
Vikram was designed to execute India’s first lunar landing, carrying with it the Pragyan rover.
However, a setback occurred when contact was lost with Vikram at a critical juncture, just moments before it was scheduled to touch down on the lunar surface. Despite this unforeseen obstacle, Chandrayaan-2’s orbiter continued to deliver valuable data, proving that India’s lunar aspirations were undeterred.
Chandrayaan-3: A Historic South Polar Landing
Fast forward to July 14, 2023, when Chandrayaan-3 was launched with renewed determination. This mission featured a lander and the Pragyan rover, both aimed at succeeding in the endeavor that Chandrayaan-2’s Vikram had been unable to accomplish – landing on the Moon’s surface.
The milestone arrived on August 23, 2023, when Chandrayaan-3’s lander successfully touched down in the Moon’s south polar region, an area believed to harbor water ice beneath its surface. This achievement marked India’s entry into an exclusive club of countries capable of lunar landings, joining the ranks of the United States, Russia, and China. The significance of this accomplishment cannot be overstated, as it further solidifies India’s standing in the realm of space exploration.
The purpose of Chandrayaan-3 is to soft land a lander on the Moon’s south pole and conduct scientific experiments to study the lunar environment, including its history, geology, and potential for resources.
The specific objectives of Chandrayaan-3 are:
- To demonstrate a safe and soft landing on the lunar surface.
- To deploy a rover to explore the lunar surface.
- To conduct in-situ scientific experiments to study the lunar environment.
- To assess the potential of the Moon for future human exploration.
The lander of Chandrayaan-3 is named Vikram, after the father of India’s space program, Vikram Sarabhai. The rover is named Pragyaan, which means “wisdom” in Sanskrit.
Chandrayaan-3 is a critical mission for India’s space program. It will help to build on the success of Chandrayaan-1 and Chandrayaan-2, and it will pave the way for future missions to the Moon.
The landing of Chandrayaan-3 on the Moon’s south pole is a particularly important goal, as this region is thought to be rich in water ice. Water ice could be used as a resource for future human exploration of the Moon, and it could also provide clues about the history of the Moon and the solar system.
The scientific experiments that will be conducted by Chandrayaan-3 will focus on a variety of topics, including the lunar surface composition, the lunar exosphere, and the lunar seismicity.
The data collected by these experiments will help us to better understand the Moon and its potential for future human exploration.
The success of Chandrayaan-3 will be a major achievement for India’s space program and for the global community.
It will demonstrate India’s capabilities in lunar exploration and it will help to advance our understanding of the Moon.
Conclusion
Chandrayaan series epitomizes India’s aspirations, innovation, and relentless pursuit of knowledge in the field of space exploration. From the groundbreaking discoveries of Chandrayaan-1 to the determined efforts of Chandrayaan-2 and the historic lunar landing of Chandrayaan-3, India’s journey to the Moon has been a remarkable odyssey that continues to inspire and contribute to our understanding of the cosmos.
