ISRO chairman announces completion of Chandrayaan 4 and 5 designs, seeking government approval for moon missions.
ISRO chairman S Somanath on Tuesday (August 20, 2024) said the space agency has completed the design for the next round of moon missions — Chandrayaan 4 and 5 — and is in the process of seeking government approval for the same.
The Chandrayaan-4 mission includes bringing back moon rocks and soil to earth after a soft landing on the lunar surface, launching a spacecraft from the moon, demonstrating a space docking experiment in lunar orbit and getting the samples back to earth.
“We have a series of missions to go to the moon. Chandrayaan-3 is over. Now, design for Chandrayaan 4 and 5 has been completed and we are seeking approval of the government,” Mr. Somanath told reporters here on the sidelines of an event organized by the All India Council for Technical Education and Indian Space Association.
Earlier, ISRO officials said that the targeted launch for Chandrayaan-4 mission was 2028.
Mr. Somanath also said that the space agency was planning to launch 70 satellites over the next five years, including a constellation of low earth orbit satellites to meet the requirements of different Ministries and departments of the government.
These 70 satellites include four for the NAVIC regional navigation system to provide positioning, navigation and time service, INSAT 4D weather satellites, the Resourcesat series of satellites, Cartosat satellites for remote sensing and high resolution imaging, he said.
Mr. Somanath said the space agency was also planning to develop the Oceansat series of satellites and technology demonstration satellites 01 and 02 to demonstrate electric propulsion systems, and quantum key distribution technologies.

Climate scientists and advocates long held an optimistic belief that once impacts became undeniable, people and governments would act. This overestimated our collective response capacity while underestimating our psychological tendency to normalise, says Rachit Dubey, assistant professor at the department of communication, University of California.
