Who is prof Manikandan Mathur, the IIT-Madras scientist who helped ISRO and NASA optimise NISAR satellite?
IIT-Madras
professor has played a pivotal role in shaping how NISAR, the Indo-US
Earth observation
satellite launched on Wednesday, will track and analyse coastal regions.
Prof Manikandan Mathur
, from the Geophysical Flows Lab at the Centre of Excellence in the Department of Aerospace Engineering, collaborated with
ISRO
and
NASA
to fine-tune the satellite's operational strategy. He provided key input on optimal imaging frequency, timing, and selection of coastal zones for monitoring.

Prof Mathur stressed the importance of closely observing the north Indian Ocean to better understand coastal processes and their links to weather systems and pollution dispersal.
His team plans to use NISAR's data to study interactions between river discharge and ocean waters in the Bay of Bengal, the dynamics of internal gravity waves along India's coasts, and how these phenomena influence regional weather patterns, including extreme rainfall and flooding.
Unlike earlier Earth observation satellites that struggled with coastal imaging and cloud interference, NISAR will offer high-resolution imagery—down to tens of metres—and revisit the same location every 12 days.

'NISAR addresses both major limitations of past missions and will also capture fine-scale Earth surface features never observed before,' Prof Mathur was quoted as saying by the Times of India.
He called the mission a "unique collaboration" that combines the strengths of two frequency bands contributed by ISRO and NASA.
Prof Mathur also highlighted the potential of open access to NISAR data to significantly advance Indian research, especially for young scientists. 'Awareness of what satellite imaging can achieve is set to grow within the Indian scientific community,' he noted.
He added that the data would also unlock new possibilities for experts in machine learning and data science to contribute to socially impactful research.

From tiny rocket to 6,500-kg satellite: ISRO chief highlights India's giant leap in space journey
ISRO Chairman and Department of Space Secretary V. Narayanan announced on Sunday that marking a remarkable turnaround in India's space journey, the Indian Space Research Organisation (ISRO) will launch a 6,500-kg communication satellite built by the US within the next couple of months. Speaking at the 21st convocation of SRM Institute of Science and Technology in Kattankulathur near Chennai, Narayanan reflected on the humble beginnings of the Indian space programme, which started in 1963 with the launch of a tiny rocket donated by the US. "It was on November 21, 1963, when the US provided us with a small rocket, marking the start of our journey. At that time, we were six to seven years behind advanced nations," he said. Narayanan, who was conferred the honorary degree of Doctor of Science by Maharashtra Governor C.P. Radhakrishnan during the event, recounted key milestones in ISRO's growth. In 1975, using satellite data provided by the US, India demonstrated the concept of mass communication by installing 2,400 television sets across 2,400 villages in six states. "From that kind of beginning, July 30, 2025, was a historic day for the Indian space programme," Narayanan noted, referring to the successful launch of the NASA-ISRO Synthetic Aperture Radar (NISAR) mission onboard the GSLV-F16. The mission, he said, carried the costliest satellite ever built in the world, featuring an L-band SAR payload from the US and an S-band payload from ISRO. "The satellite was placed in orbit with high precision, earning praise from NASA for our launcher's accuracy," he added. Narayanan said that the upcoming mission to launch the 6,500-kg American-built satellite from Indian soil using an indigenous launcher would be a symbolic moment. "A country that once received a tiny rocket from the US is now set to launch one of its largest communication satellites. This shows the phenomenal growth we have achieved," he remarked. Highlighting ISRO's achievements, Narayanan said that from having no satellite technology 50 years ago, India has now launched 433 satellites belonging to 34 countries using its own launch vehicles. "Our journey reflects not just technological progress but the determination and vision to stand shoulder to shoulder with the most advanced spacefaring nations," he added.

ISRO to launch 6,500 kg communication satellite built by U.S. in couple of months: Chairman
After marking a humble beginning in the Indian space programme with a tiny rocket supplied by the United States, ISRO would launch a 6,500 kg communication satellite built by the U.S. in the next couple of months, the Chairman of the space agency, V. Narayanan, said on Sunday (August 10, 2025). Following the historic launch of the NASA-ISRO Synthetic Aperture Radar (NISAR) mission onboard a GSLV-F16 rocket on July 30, ISRO would be launching another satellite for the United States, he said at an event near Chennai. Mr. Narayanan, who is also the Secretary, Department of Space, was presented with the honorary degree, Doctor of Science, by the Governor of Maharashtra, C.P. Radhakrishnan, during the 21st Convocation of SRM Institute of Science and Technology at Kattankulathur near Chennai. In his acceptance speech, Mr. Narayanan recalled that the ISRO was set up in 1963 and the country was 6-7 years behind advanced countries then. In the same year, a tiny rocket was donated by the United States marking the beginnings of the Indian Space Programme. 'It was on November 21, 1963,' he said. In 1975, through satellite data given by the U.S., ISRO demonstrated 'mass communication' by keeping 2,400 television sets across 2,400 villages of 6 Indian states, he said. 'From that (kind of humble beginnings), the 30th of July was a historical day for Indian space programme. We have launched the NISAR satellite. The costliest satellite ever built in the world. The L Band SAR payload from the U.S. and S Band payload provided by ISRO. The satellite was placed in orbit precisely by Indian launcher (GSLV). And today, we are shoulder to shoulder with advanced countries,' Mr. Narayanan remarked. He noted that the team from the National Aeronautics and Space Administration (NASA) appreciated their ISRO counterparts for the precision launch of the GSLV-F16/NISAR Mission. 'In another couple of months, a country which received a tiny rocket from the United States, is going to launch a 6,500 kg communication satellite built by the America using our own launcher from Indian soil. What a significant growth it is,' he noted. 'From a country which did not have satellite technology 50 years back, ISRO has, to date, launched 433 satellites of 34 countries using its own launch vehicles,' he said.
