Satish Dhawan was born on September 25, 1920, in Srinagar to Rai Bahadur Devi and Dayal Dhawan. Dhawan is a graduate of Punjab Engineering College, Chandigarh, India, Mughalpura College of Technology, Lahore, Pakistan with a Bachelor of Science in Physics and Mathematics and a Bachelor of Science in Mechanical Engineering. He also earned a Master of Arts degree in English Literature. In 1947, he earned a master's degree in aerospace engineering from the University of Minnesota, Minneapolis, and a degree in aeronautical engineering from the California Institute of Technology. He then pursued a dual doctorate in mathematics and aerospace engineering under the supervision of his advisor, Hans W.

In 1972, Dhawan became the Chairman of the Indian Space Research Organization (ISRO) and the Secretary to the Government of India for Space. He succeeded MGK Menon as the third president. APJ Abdul Kalam was the director of the satellite launch in 1979 when the satellite failed to launch into orbit and landed in the Bay of Bengal. Abdul Kalam's team knew that there was a leak in the system's fuel. However they believed the leakage was minimal. This negated the warning on the computer and they thought the fuel was fine. This miscalculation led to the failure of the mission.

Satish Dhawan, then president, called Abdul Kalam and told the media. "We lost! But I have strong faith in my team. I hope we will win next time". This surprised Abdul Kalam and the ISRO chief took responsibility for the failure. The next mission was prepared and successfully launched in 1980. When this succeeded, Satish Dhawan asked Abdul Kalam to attend the press conference alone. He shares the successes with his colleagues and bears the failures on his shoulders. When the team failed, he took the blame. But when the team won, he attributed the success to his team and portrayed the image of a great leader. Satish Dhawan was the Chairman of ISRO till 1984.
Dhawan joined the Indian Institute of Science (IISc) in Bengaluru in 1951 as a faculty member. He became its director in 1962. Although he headed the Indian Space Programme, he made considerable efforts in boundary layer research. His most important contributions are presented in the book Boundary Layer Theory by Hermann Schlichting. He set up the country's first supersonic wind tunnel at IISC. He also pioneered research on reorientating separated boundary layer flows, three-dimensional boundary layers, and transonic flows.
Dhawan conducted pioneering experiments in rural education, remote sensing and satellite communication. His efforts led to operational systems such as INSAT, a telecommunications satellite; IRS, Indian Remote Sensing Satellite; and the Polar Satellite Launch Vehicle (PSLV), which put India in the league of space-faring nations.
Former ISRO chief, and rocket scientist Satish Dhawan passed away on January 03, 2002, at the age of 81 in Bangalore. In honor of his contribution, the satellite launch pad at Sriharikota, Andhra Pradesh was posthumously renamed Satish Dhawan Space Centre. Satish Chander Dhawan Government College for Boys, Ludhiana is named after him. The Department of Mechanical Engineering building at the Indian Institute of Technology, Satish Dhawan Block, is named after him. In 2019, the Uttar Pradesh Institute of Textile Technology, Kanpur named its computer center as Prof. Satish Dhawan Computer Center. Padma Bhushan (1971) Padma Vibhushan (1981) India's highest awards. A.P.J. He is largely considered to be the man behind Abdul Kalam. Dhawan has been instrumental in the success of various satellite projects including INSAT, PSLV, and IRS. After his retirement, the government gave him various responsibilities but kept quiet. It is an expression of concern to give way to the talented.
