The Chandrayaan-1 mission was India's first lunar exploration mission. It was launched on October 22, 2008, and it successfully entered orbit around the Moon on November 8, 2008. The mission's primary goal was to study the lunar surface and to search for water ice.

The total budget for the Chandrayaan-1 mission was ₹386 crore, which is equivalent to US$48 million in 2008. This made it one of the most cost-effective lunar missions ever undertaken. The mission was a major success, and it made a number of important discoveries about the Moon.

For example, Chandrayaan-1 found evidence of water ice in the lunar polar regions. This was a major breakthrough, as it had previously been thought that the Moon was too dry to support water ice. The mission also provided valuable data about the lunar surface and its composition.

The Chandrayaan-1 mission was a major milestone in India's space program, and it helped to put India on the map as a leading spacefaring nation. The success of the mission also helped to inspire a new generation of Indian scientists and engineers.

The budget for the Chandrayaan-1 mission was relatively low compared to other lunar missions. This was due to a number of factors, including the use of indigenously developed technology and the use of a low-cost launch vehicle. The mission was also well-managed, which helped to keep costs down.

The success of the Chandrayaan-1 mission has paved the way for future lunar missions from India. In 2019, India launched the Chandrayaan-2 mission, which included a rover that successfully landed on the Moon. India is also planning to launch a third lunar mission in the near future.

The Chandrayaan-1 mission was a major success, and it has had a significant impact on India's space program. The mission has helped to put India on the map as a leading spacefaring nation, and it has inspired a new generation of Indian scientists and engineers. The success of the Chandrayaan-1 mission is a testament to the ingenuity and dedication of the Indian space community.
