Chandrayaan 2, the ambitious lunar mission by the Indian Space Research Organisation (ISRO), marked a significant milestone in India’s space exploration history. Launched on July 22, 2019, Chandrayaan 2 aimed to build on the success of its predecessor, Chandrayaan 1, by exploring the moon’s surface in greater detail and attempting a soft landing on the lunar south pole. This mission was not just a testament to India’s growing capabilities in space technology but also a leap forward in our understanding of the moon.
The Objectives of Chandrayaan 2
Chandrayaan 2 was designed with several bold objectives:
- To map the lunar surface: The mission sought to create a detailed 3D map of the moon’s surface, focusing particularly on the south polar region. This mapping would help in understanding the topographical features and mineral distribution of the moon.
- To study the moon’s exosphere: The thin atmosphere of the moon, known as the exosphere, was one of the key areas of interest for Chandrayaan 2. Understanding the exosphere could provide insights into the moon’s evolution and its interaction with solar radiation.
- To search for water ice: One of the most exciting objectives was to search for water ice in the permanently shadowed regions of the lunar south pole. The presence of water on the moon could have profound implications for future lunar exploration and even colonization.
- To study the surface composition: The mission aimed to analyze the chemical composition of the lunar surface, which could shed light on the moon’s origin and its geological evolution.
The Components of Chandrayaan 2
Chandrayaan 2 consisted of three main components: the Orbiter, the Lander (Vikram), and the Rover (Pragyan).
1. The Orbiter
The Orbiter was designed to revolve around the moon and conduct remote sensing operations. It carried eight scientific instruments, including high-resolution cameras and spectrometers. These instruments were intended to gather data on the lunar surface, map its mineral composition, and study the lunar exosphere.
2. The Lander (Vikram)
Vikram, named after Dr. Vikram Sarabhai, the father of the Indian space program, was the Lander designed to execute a soft landing on the lunar surface. It was equipped with instruments to study the moon’s seismic activity, surface temperature, and plasma density. Unfortunately, during its descent on September 6, 2019, communication was lost with Vikram just moments before its scheduled landing, and the Lander crash-landed on the lunar surface.
3. The Rover (Pragyan)
Pragyan, meaning “wisdom” in Sanskrit, was a six-wheeled Rover housed within Vikram. If Vikram had successfully landed, Pragyan would have rolled out to explore the lunar surface, analyzing soil samples and sending valuable data back to Earth. Despite Vikram’s crash-landing, the Orbiter continues to relay critical information to ISRO.
Challenges Faced by Chandrayaan 2
The mission was fraught with challenges, from technical difficulties to the inherent risks of space exploration. One of the most significant challenges was executing a soft landing on the lunar south pole, a region that had never been explored before. The rugged terrain and extreme temperatures made the task even more daunting. The loss of communication with Vikram was a setback, but it underscored the complexity of space missions and the thin line between success and failure.
Scientific Discoveries from Chandrayaan 2
Despite the loss of Vikram, Chandrayaan 2 has been a treasure trove of scientific data. The Orbiter, which continues to operate, has provided crucial insights into the lunar surface. Some of the key discoveries include:-
- Water Molecules on the Moon: The Orbiter’s imaging and spectrometer instruments confirmed the presence of water molecules on the moon’s surface, particularly in the polar regions. This finding is consistent with the data from Chandrayaan 1 and other lunar missions, but it has provided more detailed evidence.
- Topographical Mapping: High-resolution images from the Orbiter have allowed scientists to create detailed topographical maps of the moon, revealing previously unknown craters and surface features. This data is vital for future missions, particularly those planning to explore the lunar poles.
- Solar Radiation Analysis: The Orbiter’s instruments have also been studying the interaction between solar radiation and the lunar surface. This research is critical for understanding the moon’s environment and preparing for human exploration.
Chandrayaan 2’s Impact on India’s Space Program
Chandrayaan 2 was more than just a scientific mission; it was a symbol of India’s growing prowess in space exploration. The mission demonstrated India’s ability to develop and launch complex space missions on a relatively modest budget. It also showcased ISRO’s commitment to pushing the boundaries of space research and exploration.
The mission has inspired a new generation of scientists and engineers in India, sparking interest in space technology and exploration. It has also positioned India as a key player in the global space community, capable of undertaking ambitious missions and contributing valuable scientific knowledge.
The Legacy of Chandrayaan 2
While Chandrayaan 2 did not achieve all its objectives, it has left a lasting legacy. The mission’s successes and challenges have provided valuable lessons for future lunar missions, including Chandrayaan 3, which aims to achieve a successful soft landing on the moon. The data gathered by the Orbiter continues to enrich our understanding of the moon, and the mission remains a significant achievement in the annals of space exploration.
Conclusion
Chandrayaan 2 stands as a monumental achievement for India and the global space community. It has expanded our knowledge of the moon, pushed the boundaries of space technology, and inspired countless individuals to look up at the night sky with wonder. The mission is a reminder that even in the face of setbacks, the pursuit of knowledge and exploration is a journey worth undertaking.
