Indian Space Research Organization (ISRO) chief Dr. S. Somnath said that if the government approves, Chandrayaan-4 mission can be launched soon. Because ISRO has prepared the design of Chandrayaan-4 and 5. We are just waiting for the green signal from the government.
Chandrayaan-4 mission will bring samples of rocks and soil from the surface of the moon. It will have a soft landing. More important than this will be the mission of Space Docking. That is, Chandrayaan-4 will be sent into space in pieces. After this, it will be assembled in space itself. ISRO is going to do this work for the first time.

Dr. Somnath was talking to the media on the sidelines of a program of the All India Council for Technical Education of the Indian Space Association. He said that after Chandrayaan-3, we have many missions to the Moon. Earlier, ISRO officials had said that Chandrayaan-4 would be launched in the year 2028.
Preparations to launch 70 satellites in five years
Apart from this, Dr. Somnath told that ISRO is planning to launch 70 satellites in the next five years. This will also include satellites to be installed in lower orbit. Demands of many ministries are being fulfilled in this. Four satellites in this will be of NAVIC regional navigation system.
Many satellites including navigation, spying, mapping will be missed
INSAT 4D weather satellites, Resourcesat, Cartosat satellites are also included in these 70 satellites. Apart from this, some satellites will be used in remote sensing and high resolution imaging. ISRO is preparing to further develop the satellites of the Oceansat series. Demonstration 1 and 2 satellites will be launched.

Relay satellites will be launched to keep an eye on Gaganyaan
ISRO Chief Dr. Somnath said that for the Gaganyaan mission, ISRO will first launch relay satellites. So that Gaganyaan can be contacted from all around the earth. It can be monitored. Apart from this, it will also remain in contact through GSAT satellites. These satellites will be launched from America by SpaceX’s Falcon rocket. Apart from this, there will also be missions to Mercury and Venus.
What is the preparation for connecting Chandrayaan-4 in space
ISRO Chief said that Chandrayaan-4 will not be launched in one go. The parts of Chandrayaan-4 will be launched in space in two times. After this, while going towards the moon, the parts of Chandrayaan-4 will be joined in space itself. That is, it will be assembled. The advantage of this will be that in future our space station will be built by joining it in this way.

By assembling Chandrayaan-4 and its parts in space, ISRO will also acquire the technology and capability to build a space station in the future. Therefore, Chandrayaan-4 mission is extremely important. Dr. S. Somnath said that we have done all the planning for Chandrayaan-4. How will we launch it? Which part will be launched when?
After this, how will it be assembled in space. Then how will it be landed on the moon. Which part will remain there. Which part will return to India with the sample. Many launches will have to be done because we do not have a rocket powerful enough to launch Chandrayaan-4 in one go.

This year we will show the technology to connect spacecraft in space
ISRO Chief said that we have the technology of docking i.e. joining the parts of spacecraft. This work can be done both in the space of the Earth and the space of the Moon. That is, above the Earth as well as above the Moon. We are developing this technology of ours. ISRO will send SPADEX mission by the end of this year to demonstrate the docking technology.
The two parts of Chandrayaan-4 will be joined in space above the earth
Docking maneuvers are a routine process while returning to Earth after completing the mission on the Moon. We have done this work before. The world has seen this in different missions of Chandrayaan. We landed some parts of a spacecraft on the Moon while another part kept revolving around the Moon. This time we will demonstrate the work of joining them. But this time we will do the work of joining the two modules of Chandrayaan-4 in the Earth’s orbit.
