On 23 August, the India achieved a huge success, having managed to land a spacecraft on the surface of the moon, as part of the mission Chandrayaan-3. Thus, it became the fourth nation to reach the Moon and the first nation to land at the south pole of the moon. After this success, India wants to continue the research, to take samples from the lunar south polar region (Chandrayaan-4) and return them to Earth.
It is said that the Indian Space Research Organisation (ISRO) is planning the new mission to moon, Chandrayaan-4, for the collection of samples. Four modules will be sent to the moon in two launches.

Initially, they will be sent a lander and a "ascender" on the surface of the moon to collect samples. This will probably happen near the landing site of the Chandrayaan-3 spacecraft, near the lunar south pole. This area is of great interest to scientists because it is believed to be the site abundant Water in the form of ice.
The remaining two pieces of the Chandrayaan-4 mission, a a transfer unit and a re-entry unit, are said to be sent later via a second rocket, but will remain stationed in lunar orbit.
Although the specific mission plan is not yet clear, it appears that the lander and ascender will touch the rim of an undefined crater near the south pole. The ascender will then carry the samples in the re-entry unit. The transport and re-entry units will head back to Earth, bringing with them the samples from the moon.
“It's a very ambitious mission.", said the Nilesh Desai, director of the Space Application Center in Ahmedabad, which was part of the historic Mission Chandrayaan-3. "Hopefully, in the next five to seven years, we will be able to meet this challenge.“.

Importance of missions to the moon
Sample collection missions from the moon are very important. The study of samples can offer us new scientific knowledge. One of the areas that can be explored is geology of the moon. The samples can give us information about the composition of the moon, the age of the rocks and the geological processes that have taken place there.
In addition, the study of the samples can reveal information about the history of solar our system. Moon rocks may contain traces of the primitive birthplace of our solar system and help us understand the process of planet formation.

Also, the samples could help us understand if it exists, after all, Water on the moon. The detection Waterύ can indicate the presence of hydrological processes in the past and open up new perspectives for lunar exploration.
Finally, the study of moon samples can reveal interesting elements and for the creation of the Earth.
