ISRO chief sets new dates: 2026 for Gaganyaan, Chandrayaan-4 likely in 2028

ISRO Chairman S. Somanath emphasized the importance of increasing the indigenisation of India’s space technologies, stating that the country aims to expand its share of the global space economy to at least 10 percent within the next decade, up from the current 2 percent.

During the Sardar Patel Memorial Lecture at Akashvani (All India Radio), Somanath also shared updated timelines for key missions: the manned Gaganyaan mission is targeted for 2026; the Chandrayaan-4 sample return mission is set for 2028; and the long-delayed India-US collaborative NISAR mission is scheduled for next year.

He further announced a planned joint moon-landing mission with Japan’s space agency, JAXA, now designated as Chandrayaan-5. Previously known as LUPEX (Lunar Polar Exploration), this mission was originally slated for around 2025 but is now expected to follow Chandrayaan-4, placing its likely launch post-2028.

ISRO Chief’s statement

“It would be a very heavy mission in which India would provide the lander, while the rover would come from Japan. The rover on Chandrayaan-3 was only about 27 kg in weight. But this mission would carry a 350-kg rover. It is a science-heavy mission which would take us one step closer to landing human beings on the moon,” Somanath said. India has unveiled plans of having a manned mission to the moon by 2040.

Somanath said the opening of the space sector to private enterprise, new enabling policies, and the enthusiasm shown by young entrepreneurs had created a vibrant space ecosystem in India.

“But our contribution to the global space economy is still about 2 per cent. We aspire to increase it to about 10 per cent in the coming 10-12 years. But ISRO cannot achieve this alone. We need the participation of other stakeholders. Start-ups to big companies, all need to come and participate in India’s space sector. We have been working hard to create those enabling mechanisms that will make it easy for companies to work with ISRO,” he said.

“Several industries, big and small, have expressed interest in investing in the space sector. And ISRO is doing its best to help them come and participate. Lots of activities that could traditionally be done only by ISRO are now being done by private industry. Rockets are a good example. These kinds of things were already happening in some other countries. These have begun to take shape in India as well. We are helping, empowering, guiding these companies,” Somanath said.

The ISRO chairman said India’s dependence on imports of space technologies had decreased significantly in the last one decade, but there was much more that needed to be done, including manufacturing and research and development.

“A lot of critical items used in the space sector still come from outside. We will have to create the capability to build a lot of these within our country. There has to be greater indigenisation of advanced research and development as well,” he said.

Somanath said while India had a very old and rich tradition of observing and studying stars and galaxies, it was after a long time that the country was producing new knowledge in the field of astronomy and contributing to global efforts in space exploration.

“Chandrayaan-3 was not just about making a soft landing on the Moon. It was of course important, but the mission also produced very interesting scientific outcomes. Even Chandrayaan-1 produced excellent science outcomes, it confirmed the presence of water on the moon. The same is the case with Aditya-L1 and XPoSat missions. All of them are generating new science and data that progress global knowledge. Astrosat (which has been operational since 2015), for example, has resulted in more than 400 scientific papers and over 30 PhDs,” Somanath said.
