Ex-ISRO Scientists Slam R Madhavan’s ‘Rocketry’ As ‘Fake’ & Say, ‘90% Of The Film Is False’


A group of former ISRO scientists have criticised R Madhavan’s Rocketry: The Nambi Effect, claiming that 90% of the material depicted in the film is false.


They’ve also claimed that the majority of Nambi Narayanan’s comments in the movie, including his correction of APJ Abdul Kalam, are untrue.

Dr. A. E. Muthunayagam, Director – LPSE, ISRO; Prof. E. V. S. Namboothiri, Project Director – Cryogenic Engine; D. Sasikumaran, Deputy Director – Cryogenic Engine; and other former ISRO scientists were in attendance at the news conference.

“We are obligated to inform the public about some issues,” they told the media, “since Nambi Narayanan has been disparaging ISRO and other scientists through the film Rocketry: The Nambi Effect, as well as through television networks. He is not the father of numerous projects, as he claims to be. Even in the movie, he claimed to have corrected APJ Abdul Kalam, who would later become the president of India. That is likewise untrue.

They further mentioned that Narayanan hardly ever collaborated with APJ Abdul Kalam.

remarked Dr Muthunayagam “90% of the information provided is false. Many former scientists have called me after seeing the movie to complain that Nambi has gotten all the credit.”

He went on to say,

“I have requested specific information from the current ISRO Chairman regarding the claims Nambi made in the movie regarding the cryogenic engine being shipped from Tashkent. This is likewise incorrect, and I will take the necessary action as soon as I receive the information I’ve requested “.

In 1968, Narayanan enlisted in the military and spent 26 years working under Dr Muthunayam.

The claim made in the movie by Nambi Narayanan that his imprisonment prevented India from acquiring cryogenic technology has also been debunked.

They stated, “EVS Nambuthiri was in charge of this when ISRO began the process of constructing its own cryogenic engine in the middle of the 1980s. 12 volumes were created by a team under the direction of EVS Namboothiri. Nambi Narayanan wasn’t involved in cryogenics at the time. Nambi Narayan was not a member of the team that later began the cryogenic engine’s development, which was headed by Gnana Gandhi.

When the Cryogenic Propulsion System project at LPSC began in 1990, “I appointed Nambi Narayanan as the project director,” Muthunayakam recalled.

He continued by stating that Narayanan wasn’t awarded the Padma Bhushan for his work at ISRO, but rather for another reason.

In the movie, Narayanan made another claim that has been debunked by scientists: he invented the Vikas engine. It was allegedly created by the French Viking engine.

“Vikas engine is the accomplishment of a large scientific team,”

D Sasikumaran, who was charged with espionage with Nambi Narayanan earlier this month, called the movie “sad and is practically comparable to treason.”


He further asserted that neither he nor Nambi had been mistreated while in police custody.

R. Madhavan and Nambi Narayanan have not yet responded to the allegations made by former scientists.

R Madhavan wrote, created, and oversaw the production of the movie.
