Chandrayaan-3: second bet to land on the Moon in November 2020

BENGALURU: El (Isro), who failed to land a probe in Moon On his first attempt in September 2019 (), he began working at Chandrayaan-3 with a November 2020 deadline, sources said.

Isro has formed multiple committees, a general panel and three subcommittees, and has held at least four high-level meetings since October. The new mission will include only one landing module and one scout vehicle, as the Chandrayaan-2 orbiter works well. On Tuesday, the general committee met with the Chandrayaan-3 configuration review agenda. He also examined the recommendations of several subcommittees on propulsion, sensors, general engineering, navigation and guidance.

The work is in full flow, said a scientist. So far, Isro has analyzed 10 specific aspects of the mission, including landing site selection, absolute navigation and local navigation. The sources cited an office order issued on October 5 for having instructed: It is essential to carry out a detailed analysis of the changes to improve the landing system taking into account the recommendations of both the expert committee (formed to examine Chandrayaan-2 ) as of the recommendations that could not be implemented due to the advanced stage of preparation of the Chandrayaan-2 flight.

Another scientist said that for the new mission is to strengthen the legs of the landing module, so that it allows landing even at high speed. Sources said Isro will build a new landing module and a surface vehicle. No final decision has been made on the number of payloads in the landing module.

A source said Isro's teams are looking to have a detachable module that carries fuel. Tentatively called the propulsion module, it will help carry the landing module, which will have the rover sitting inside the landing module, at the mole, the source said. In Chandrayaan-2, the fuel transported in the orbiter was used for all maneuvers performed after launch and until the landing module was separated. Here, the propulsion module will help this process. Isro is also looking to reduce the amount of maneuvering around the Earth and also during transit to the lunar orbit. Instead of six maneuvers, we can have only three or four, a source said.
