R Madhavan's film Rocketry: The Nambi Effect released in the theaters on July 1.

R Madhavan brought alive the story of Nambi Narayan, a former scientist and aerospace engineer of the Indian Space Research Organisation 

The film earned rave reviews from fans and critics alike. 

The story spans across Narayanan's days as a graduate student at Princeton University, before exploring his work as a scientist and the false espionage charges placed upon him. 

Ronak Kotecha of The Times of India rated the film 3.5 out of 5 stars and wrote "‘Rocketry takes off well, hits some turbulence on the way, but eventually soars high with real characters and moving moments that make it worth your while". 

Nandini Ramnath of Scroll.in rated the film 2.5 out of 5 stars and wrote "Before it launches into its main argument, Rocketry lurches from one amateurish eureka moment to the next" 

A critic for Pinkvilla rated the film 3 out of 5 stars and wrote "Rocketry: The Nambi Effect is a well made biopic that documents the life of Nambi Narayanan in the best possible manner". 

– R. Madhavan as Nambi Narayanan

Rocketry: The Nambi Effect opened to mixed reviews at the theatres on July 1. However, it recorded a rather low start at the box office.  

Rocketry managed to earn around Rs 75 lakh. Given Madhavan's strenuous promotional activities, it is expected that the business of Rocketry might increase in the coming days.
