Chandrayaan-4 mission is a step towards a manned lunar mission scheduled for 2040
In a series of ambitious approvals, the Indian Cabinet, chaired by Prime Minister Narendra Modi, has set the stage for a significant leap in space exploration and technology development. The new initiatives, announced after a meeting on Wednesday (September 18, 2024), include the Chandrayaan-4 mission to the Moon, a scientific mission to Venus, and the development of a next-generation reusable launch vehicle.

India's Chandrayaan-4 Mission 
Building on the success of Chandrayaan-3, the Indian government has sanctioned the Chandrayaan-4 mission, a continuation of India's lunar exploration program. The mission, costing Rs. 2104.06 crore aims to develop and demonstrate technologies essential for landing on the Moon and safely returning to Earth. These technologies include docking/undocking, landing, lunar sample collection, and safe return maneuvers.

Expected to be completed within 36 months, Chandrayaan-4 will engage various Indian industries and academia, significantly boosting employment and leading to technological spillovers into other sectors. This mission is not only a step towards a manned lunar mission scheduled for 2040 but also towards establishing a permanent Indian presence in space as envisioned with the proposed Indian Space Station by 2035.

Venus Orbiter Mission in 2028
Following lunar and Martian explorations, India is now setting its sights on Venus with the approval of the Venus Orbiter Mission (VOM). With a budget of Rs. 1236 crore, the VOM is designed to orbit Venus and delve into its atmospheric conditions and geological features. The mission, slated for launch in March 2028, aims to enhance our understanding of how planetary environments evolve, offering insights into Earth's own environmental trajectory.

The data from VOM will be shared with the global scientific community, facilitating a deeper understanding of Venus, often referred to as Earth's "sister planet" due to its similar size and proximity. This mission is expected to pave the way for future planetary missions and foster significant involvement from the Indian industrial and academic sectors.

New Reusable Low-cost Launch Vehicle
The Cabinet has also green-lighted the development of a Next Generation Launch Vehicle (NGLV), a project that marks a significant milestone in India's space ambitions. This new launch vehicle will be capable of carrying payloads up to 30 tonnes to Low Earth Orbit (LEO), tripling the current capacity and incorporating reusability to reduce costs.

With a total fund allocation of Rs. 8240.00 crore, the NGLV project includes three development flights and is expected to take 96 months to complete. The development of this vehicle is integral to India's plans for future crewed lunar missions and the operation of the proposed Bharatiya Antariksh Station.

These new initiatives by the Indian government highlight a strategic and forward-looking approach to space exploration and technology. By investing in advanced missions to the Moon and Venus and developing cutting-edge launch vehicles, India is poised to significantly enhance its stature in the global space community while driving technological innovation and economic growth at home. These missions will not only deepen our understanding of the universe but also ensure India's continued prominence in the rapidly evolving space sector.
