During the 62nd foundation day celebration of the Indian Institute of Tropical Meteorology in Pune, Nilesh Desai, Director of the Space Applications Centre (SAC/ISRO), revealed key details about the Chandrayaan-4 mission. The mission is set to involve the retrieval of soil samples from the lunar surface, marking a significant advancement in India’s lunar exploration program.
The decision to focus on sample return underscores the scientific objectives of Chandrayaan-4, aiming to bring back valuable lunar soil samples for detailed analysis. The samples will provide crucial data for researchers and scientists, offering insights into the composition and geological history of the Moon.
The announcement further solidifies India’s commitment to pushing the boundaries of space exploration and contributing to scientific knowledge on a global scale. Chandrayaan-4’s mission to collect and return lunar soil samples places India among the elite group of nations with the capability to execute complex and technologically demanding lunar exploration endeavors.
As ISRO progresses with Chandrayaan-4, the mission is poised to be a landmark achievement, showcasing India’s growing prowess in space science and reinforcing its position as a key player in the global space exploration arena. The ambitious nature of the mission reflects India’s dedication to advancing space research and making substantial contributions to humanity’s understanding of celestial bodies.
Nilesh Desai, Director of the Space Applications Centre (SAC/ISRO), provided further insights into the Chandrayaan-4 mission, detailing its ambitious approach. According to Desai, the landing strategy for Chandrayaan-4 will be similar to Chandrayaan-3, where the central module will return after docking with the orbiting module. However, a distinctive feature of Chandrayaan-4 involves the separation of the central module near the Earth’s atmosphere. The re-entry module, carrying soil and rock samples from the Moon’s surface, will then return with the collected lunar material.
Desai described the mission as highly ambitious, emphasizing the challenge of bringing back lunar soil samples. He expressed confidence in ISRO’s capabilities, stating that the organization hopes to meet this ambitious challenge within the next five to seven years.
The detailed landing and sample return strategy outlined by Desai highlights the technological complexity and precision required for Chandrayaan-4. The mission’s innovative approach and the intention to retrieve lunar material for scientific analysis underscore India’s commitment to advancing space exploration and contributing valuable data to the global scientific community.
As ISRO progresses towards Chandrayaan-4, the mission’s success would not only mark a significant milestone for India’s lunar exploration program but also reinforce the nation’s position as a capable and pioneering player in the field of space science and research. The ambitious timeframe outlined by Desai reflects ISRO’s determination to overcome challenges and make substantive contributions to our understanding of the Moon’s composition and geological history. 
Chandrayaan-4 is poised to be a more intricate and ambitious mission compared to its predecessor, Chandrayaan-3. Notably, the planned rover for Chandrayaan-4 is expected to weigh a substantial 350 kg, significantly larger than the 30 kg rover deployed in Chandrayaan-3. This increase in size poses a heightened technical challenge for the mission, requiring advanced engineering and precise execution.
The complexity of Chandrayaan-4 is further accentuated by its intended landing site on the Moon’s rim, an area that has not been explored before. Landing on the Moon’s rim demands a high degree of precision, and the mission aims to achieve this in order to conduct scientific exploration in a novel and uncharted region.
In addition to the increased rover size and challenging landing site, Chandrayaan-4 is designed to have a more expansive exploration area. The rover’s designated exploration zone is set to cover 1 km x 1 km, offering a substantially larger area for scientific investigation compared to Chandrayaan-3’s exploration zone of 500 meters x 500 meters.
The mission’s emphasis on exploring new lunar territories and conducting in-depth scientific analysis of the Moon’s surface underscores India’s commitment to pushing the boundaries of space exploration. Chandrayaan-4’s objectives go beyond the accomplishments of its predecessors, reflecting a strategic evolution in India’s lunar exploration program and its aspirations to contribute significantly to our understanding of the Moon’s composition and geological features.
As Chandrayaan-4 advances towards implementation, the mission’s complexities and technical challenges highlight the cutting-edge capabilities of the Indian Space Research Organisation (ISRO) and its role in driving innovation and exploration in the field of space science.
The success of Chandrayaan-4 hinges on its ability to execute the challenging task of returning lunar soil samples to Earth. This intricate process involves a series of precise maneuvers, including the lander module docking with the orbiting module in space. Subsequently, the central module, containing the collected lunar samples, will detach and return to Earth.
The operation’s complexity is underscored by the involvement of two launch vehicles, emphasizing the scale and technical intricacy of the mission. The use of multiple launch vehicles signifies the need for coordinated and synchronized efforts to ensure the successful execution of each phase of the mission.
The docking and return process is a critical component of Chandrayaan-4, requiring advanced technology and precise coordination to achieve a seamless transition between the lunar surface and Earth. The success of this phase will determine the mission’s ability to bring back valuable lunar soil samples for scientific analysis.
The inclusion of multiple launch vehicles in Chandrayaan-4 reflects the mission’s ambitious goals and the technological advancements employed by the Indian Space Research Organisation (ISRO) to undertake complex space exploration endeavors. As India aims to contribute significantly to lunar research, Chandrayaan-4 stands as a testament to the nation’s commitment to pushing the boundaries of space science and exploration.
While the challenges are formidable, the successful execution of the docking and return process will position Chandrayaan-4 as a milestone achievement, solidifying India’s standing in the global space exploration community and advancing our understanding of the Moon’s geological composition.
In addition to the Chandrayaan-4 mission, the Indian Space Research Organisation (ISRO) is engaging in collaboration with the Japanese space agency JAXA for another lunar mission named LuPEX. This joint mission aims to explore the Moon’s darker side, which has not been extensively studied.
LuPEX, which stands for Lunar Polar Exploration, will feature a rover with a weight of up to 350 kg, emphasizing the significant size and capabilities of the exploration vehicle. The rover is slated to explore areas on the lunar surface with a latitude of up to 90 degrees, covering regions that are crucial for scientific investigation.
The collaboration between ISRO and JAXA on the LuPEX mission showcases international cooperation in lunar exploration and reinforces the commitment to advancing our understanding of the Moon’s diverse and unexplored terrains. The joint effort leverages the expertise and resources of both space agencies to undertake a comprehensive exploration mission.
The exploration of the Moon’s darker side and the deployment of a robust rover with advanced capabilities underline the scientific objectives of LuPEX. As the mission progresses, it is poised to contribute valuable data that will enhance our knowledge of lunar geology, composition, and the unique features of the Moon’s less illuminated regions.
ISRO’s participation in collaborative lunar missions demonstrates India’s active role in international space exploration initiatives and the nation’s dedication to advancing scientific research beyond Earth.
