K. Sivan: Former ISRO Chairman

A mango farmer’s son, taught in a Tamil-medium government school, went on to lead India’s space programme. K. Sivan spent decades building rocket engines before the world watched him, as ISRO Chairman, react live as Chandrayaan-2’s lander went silent just short of the Moon.

K. Sivan: ISRO‘s Rocket Man

From a Tamil-medium village school to chairing India’s space programme through its most-watched Moon mission.

1982

Joins ISRO

Starts on the PSLV project, straight after his master’s degree from IISc.

2014

Director, Liquid Propulsion Systems Centre

Takes charge of ISRO’s cryogenic-engine work, earning the nickname ‘Rocket Man.’

2018

Becomes ISRO Chairman

The 9th Chairman of ISRO, also Secretary, Department of Space.

Jul 2019

Chandrayaan-2 launches

The Vikram lander loses contact just before touchdown; the orbiter keeps working.

The pattern: Sivan’s path ran entirely through hands-on engineering, from PSLV trajectories to cryogenic engines, before he ever held an administrative title. By the time he was Chairman, he’d built the rockets himself.

Must Know

Kailasavadivu Sivan was born on 14 April 1957, in Sarakkalvilai, Kanyakumari district, Tamil Nadu. He was the first graduate in his family.
He earned a B.Tech in Aeronautical Engineering from Madras Institute of Technology in 1980, and a Master’s in Aerospace Engineering from IISc Bangalore in 1982.
Sivan joined ISRO in 1982, working on the Polar Satellite Launch Vehicle (PSLV) project. He earned a PhD in Aerospace Engineering from IIT Bombay in 2006.
He was appointed Director of ISRO’s Liquid Propulsion Systems Centre in July 2014, and Director of the Vikram Sarabhai Space Centre (VSSC) in June 2015.
Sivan became the 9th Chairman of ISRO, taking office on 15 January 2018. He also served as Secretary, Department of Space, and Chairman of the Space Commission.
Under his chairmanship, ISRO launched Chandrayaan-2 on 22 July 2019. The Vikram lander and Pragyan rover lost contact during descent, though the orbiter continued functioning.
His term was extended by a year in December 2020, and he served as ISRO Chairman until 14 January 2022, when S. Somanath succeeded him.

Good to Know

Sivan grew up as the son of a mango farmer, and studied in a Tamil-medium government school in his village before going on to engineering college.
He played a major role in reviving ISRO’s GSLV programme, and led development of SITARA, a 6D trajectory simulation software still used at ISRO.
His work on cryogenic engine technology, essential for launching heavier payloads, earned him the nickname “Rocket Man.”
In February 2017, while Sivan was VSSC Director, ISRO set a world record by launching 104 satellites on a single PSLV rocket.
He received the Dr. A.P.J. Abdul Kalam Award in 2019, and the IEEE Simon Ramo Medal (shared with B.N. Suresh) in 2020.
Sathyabama University, Chennai, conferred an honorary Doctor of Science on him in 2014.
He is a Fellow of the Indian National Academy of Engineering, the Aeronautical Society of India, and the Systems Society of India.
After leaving ISRO, Sivan was appointed Chairman of the Board of Governors at IIT Indore, in August 2023.

Great to Know

Sivan’s entire path to the top ran through hands-on engineering roles, not administration. By the time he became Chairman, he had personally worked on trajectory design, propulsion systems, and cryogenic engines.
Chandrayaan-2’s partial setback didn’t end India’s lunar ambitions. The lessons from Vikram’s loss of contact directly shaped Chandrayaan-3, which achieved a successful soft landing under his successor, S. Somanath, in 2023.
Sivan’s rise, from a Tamil-medium village school to leading India’s space agency, mirrors a broader pattern among India’s scientist-administrators. See SciTech0076 — U.R. Rao: Father of India’s Satellite Programme, another ISRO leader who rose through hands-on research rather than administrative rank alone.
His move to chair IIT Indore’s Board of Governors after ISRO reflects a common pattern for retired Indian scientist-administrators: continuing to shape institutions, just in a different sector.
