Chandrayaan-3 is the successful one. It is the third lunar exploration mission undertaken by the Indian Space Research Organisation (ISRO). The mission successfully soft-landed on the lunar surface on August 23, 2023, at 6:04 PM IST. It is the first country to land on the south pole of the Moon.
The previous Chandrayaan missions, Chandrayaan-1 and Chandrayaan-2, were also successful in their own way. Chandrayaan-1 orbited the Moon and made several important discoveries, including the presence of water ice on the lunar surface. Chandrayaan-2 was the first mission to attempt a soft landing on the Moon’s south pole, but it failed due to a technical glitch.
The success of Chandrayaan-3 is a major achievement for the ISRO and for India. It demonstrates the country’s growing capabilities in space exploration. The mission will help scientists to better understand the Moon’s geology and its potential for resources. It will also help to pave the way for future human missions to the Moon.
How many days Chandrayaan-3 will work?
Chandrayaan-3 is designed to work for 14 days, which is equivalent to one lunar day. This is because the Moon’s rotation period is 27.3 days, and the lander and rover will only be able to operate in the sunlight. After 14 days, the Moon will enter its night phase, and the lander and rover will become inactive.
However, the ISRO is hoping that the mission life of Chandrayaan-3 can be extended beyond 14 days. They are working on ways to improve the efficiency of the lander and rover, and they are also exploring the possibility of using solar panels to generate power during the night.
If the mission life of Chandrayaan-3 can be extended, it will be a major achievement for the ISRO. It will allow scientists to collect more data about the Moon, and it will also help to pave the way for future human missions to the Moon.
