Exploring the Lunar Frontier: India's Endeavor with Chandrayaan Missions
Introduction
India's space exploration journey has been marked by remarkable achievements and ambitious projects. Among these, the Chandrayaan missions stand out as pioneering endeavors to uncover the mysteries of the Moon. With a focus on the Chandrayaan 3 mission and a retrospective look at Chandrayaan 1, India's space agency, the Indian Space Research Organisation (ISRO), continues to make strides in expanding our understanding of lunar landscapes and beyond.

Chandrayaan 3: A Historic Soft Landing
The Persistence of the Orbiter
As the orbiter of Chandrayaan 2 continues its journey around the Moon, it maintains a polar orbit at an altitude of 100 km. With a planned mission lifetime of seven and a half years, the orbiter plays a vital role in relaying data and observations back to Earth.
The Vikram Lander's Aspirations
The Chandrayaan 2 mission, which included the Vikram lander, aimed for a groundbreaking soft landing on the Moon's south polar region on 7th September 2019. This region was of particular interest due to the potential presence of water ice beneath the surface. Regrettably, the mission faced a setback as contact with the Vikram lander was lost at an altitude of 2 km before its intended touchdown.
Lessons from Chandrayaan 2
The Chandrayaan 2 mission, although not achieving its desired landing, provided invaluable insights and learning opportunities. Both the Vikram lander and the Pragyan rover were designed for a lunar day's operation (equivalent to 14 Earth days). The mission's challenges reinforced the complexities of soft landings and the critical importance of robust communication systems.
Chandrayaan 1: Pioneering Deep Space Exploration
Inaugurating the Lunar Journey
Chandrayaan 1 marked ISRO's maiden deep space mission. Launched on 22 October 2008, the spacecraft weighed 590 kg and was propelled into space by a PSLV-C11 launch vehicle from the Satish Dhawan Space Center. The mission was conducted with a budget of Rs. 386 crores, reflecting India's commitment to space exploration.
Moon Impact Probe and Lunar Atmosphere Study
A significant component of Chandrayaan 1 was the Moon Impact Probe (MIP), designed to test landing systems and study the lunar atmosphere. In a calculated move, ISRO directed MIP to crash near the Shackleton crater at the Moon's south pole on 14 November 2008. Prior to its impact, MIP made a groundbreaking discovery, detecting traces of water in the Moon's atmosphere.
Unexpected Discoveries and Longevity
The Chandrayaan 1 mission was designed for a two-year operational span. However, ISRO encountered radio communication loss with the spacecraft on 28 August 2009. In an astonishing turn of events, NASA located Chandrayaan 1 orbiting the Moon in 2017, showcasing ISRO's technical prowess and the resilience of the spacecraft.
ISRO: A Trailblazing Force in Space Exploration
Inception and Evolution
The Indian Space Research Organisation (ISRO) was founded on 15 August 1969, with its headquarters situated in Bengaluru. Guided by the visionary leadership of Vikram Sarabhai, who also served as its first chairman, ISRO swiftly established itself as a global player in space research and technology.
A National Endeavor
ISRO holds the distinction of being India's national space agency, dedicated to harnessing space technology for diverse applications. Its endeavors span satellite communication, Earth observation, navigation, and interplanetary exploration.
Conclusion
In the relentless pursuit of knowledge and exploration, India's ISRO has etched its name among the pioneers of space research. The Chandrayaan missions epitomize this spirit, with Chandrayaan 3 poised to achieve a historic soft landing and Chandrayaan 1 leaving an indelible mark on lunar exploration. As ISRO continues its journey into the cosmos, the agency's commitment to innovation, discovery, and technological advancement remains unwavering.
