Touted to be the first biography of astronaut Shubhanshu Shukla, the new book, "Sky Was Never the Limit", delves into the remarkable journey of India's decorated fighter pilot, test pilot, and space mission commander, offering thrilling glimpses into life behind the cockpit and within India's elite aviation community.

Written by documentary filmmaker Narayan R and published by Rupa, the book offers an emotional narrative behind a "seemingly stoic spacefarer".

Shukla, a Group Captain in the Indian Air Force (IAF), who was part of the Axiom-4 private space mission that lifted off from Florida on June 25 and docked at the International Space Station (ISS) on June 26, made history as the second Indian astronaut to travel to space after Rakesh Sharma's 1984 mission.
