Chandrayaan-1 Mission: Laying the Lunar Foundation

India’s enthralling lunar exploration voyage commenced with the historic launch of Chandrayaan-1 on October 22, 2008. This mission, which marked the Indian Space Research Organisation’s (ISRO) inaugural venture into lunar exploration, set the stage for India’s celestial aspirations. Let’s unravel the key facets of Chandrayaan-1:

Mission Objectives:

  1. Orbiting the Moon: Chandrayaan-1 aimed to insert an orbiter into lunar orbit to conduct extensive observations and studies from above.
  2. Characterizing the Moon: The mission sought to unravel the lunar surface’s mysteries, including its mineral composition, geological history, and presence of water molecules.


  • Water Discovery: Chandrayaan-1 achieved a monumental breakthrough by detecting water molecules on the Moon’s surface, particularly near the lunar poles. This groundbreaking revelation transformed our understanding of the lunar environment and opened doors to future lunar exploration endeavors.
  • Cartographic Marvel: The mission’s instruments meticulously mapped the Moon’s surface, offering high-resolution images and invaluable data for upcoming lunar missions.
  • The Moon Impact Probe (MIP): As part of Chandrayaan-1, the Moon Impact Probe (MIP) executed a controlled crash landing on the lunar surface, providing close-up observations that enriched our lunar knowledge.
  • International Collaboration: Chandrayaan-1 also spotlighted India’s capacity for international collaboration, exemplified by partnerships with esteemed space agencies like NASA, which contributed instruments to the mission.

Chandrayaan-2 Mission: India’s Monumental Leap

Building upon the success of Chandrayaan-1, India undertook an even more audacious lunar mission, Chandrayaan-2. Launched on July 22, 2019, this mission embodied India’s commitment to comprehensive lunar exploration, featuring an orbiter, a lander, and a rover. Let’s delve into the intricate details of Chandrayaan-2:

Mission Components:

  1. Orbiter: The orbiter, a cornerstone of Chandrayaan-2, embarked on an overarching mission to scrutinize the lunar surface from orbit. It brimmed with advanced instruments poised to capture high-resolution images and collect critical scientific data.
  2. Lander (Vikram): At the heart of Chandrayaan-2 lay the lander, christened Vikram. This indomitable component was entrusted with the arduous task of executing a soft landing near the lunar south pole.
  3. Rover (Pragyan): The rover Pragyan, ferried by the lander, was designed to be the moon’s intrepid explorer. It was equipped to traverse the lunar terrain, analyze soil samples, and conduct experiments.

Mission Objectives:

  • South Pole Exploration: Chandrayaan-2 was specifically engineered to explore the enigmatic lunar south pole, a region of profound scientific interest owing to its potential water ice reserves.
  • Scientific Investigations: Armed with an array of scientific instruments, the orbiter and lander embarked on a quest to fathom the lunar surface’s nuances, mineral composition, and topographical intricacies.
  • Technology Demonstrations: Beyond scientific endeavors, Chandrayaan-2 showcased India’s technological acumen, with a particular focus on achieving a soft lunar landing.

Accomplishments and Challenges:

  • Orbiter Triumph: While the lander faced a setback, the orbiter emerged victorious, successfully entering lunar orbit and continuing to relay invaluable data to Earth. Its instruments have played a pivotal role in decoding the lunar surface and pinpointing water ice deposits.
  • Lander Setback: Regrettably, the lander Vikram encountered adversity during its descent, leading to a hard landing and the subsequent loss of the rover Pragyan. Nevertheless, the indomitable spirit of Chandrayaan-2 persists through the orbiter, which continues to fulfill its mission objectives.
  • Global Attention: Chandrayaan-2 captivated international attention, affirming India’s burgeoning significance in the realm of space exploration and lunar research.

Chandrayaan-3 Mission: A Successful Landing and Exploration

India’s Chandrayaan-3 mission successfully landed on the moon’s south pole on August 23, 2023. The lander, Vikram, deployed the Pragyan rover to explore the cratered surface. The rover sent back videos of its environment and started working on its research objectives.

The Chandrayaan-3 mission was launched on July 14, 2023, and entered lunar orbit on August 5, 2023. The Vikram lander then separated from the propulsion module and began its descent to the lunar surface. The lander touched down successfully at 12:33 UTC.


After landing, the Vikram lander deployed the Pragyan rover. The rover is about the size of a golf cart and is equipped with a variety of scientific instruments to study the lunar surface. The rover sent back videos of its environment and started working on its research objectives, which include studying the composition of the lunar soil, searching for water ice, and investigating the moon’s magnetic field.

The Chandrayaan-3 mission was a major success for India and a significant step forward in our understanding of the moon. The mission is expected to last for one year, during which time the lander and rover will conduct a variety of scientific experiments to study the moon’s surface and composition.

The success of the Chandrayaan-3 mission is a testament to the hard work and dedication of the scientists and engineers at the Indian Space Research Organisation (ISRO). It is also a major boost for India’s space program and helps to put the country in the forefront of lunar exploration.

Future of the Lander and Rover

On September 3, 2023, the rover was put into sleep mode after it had completed all of its assignments. Its batteries were charged and receiver left on, in preparation for the impending lunar night. The lander and rover were expected to operate only for one lunar daylight period, or 14 Earth days, and the on-board electronics were not designed to withstand the −120 °C (−184 °F) nighttime temperatures on the Moon. If the rover and lander were to survive the lunar night, the mission is planned to be extended for further science operations.

The Chandrayaan-3 mission is a significant step forward in our understanding of the moon. The data collected by the lander and rover will help scientists to better understand the moon’s formation, evolution, and potential for future human exploration. The success of the mission is a major achievement for India and a boost for the country’s space program.
