Ormakalude Bhramanapadham (Malayalam: ഓർമകളുടെ ഭ്രമണപഥം) is the autobiography of Nambi Narayanan, former Indian Space Research Organisation (ISRO) scientist and the Padma Bhushan awardee.

He came to India with expertise in liquid propulsion at a time when Indian rocketry was still solely dependent on solid propellants.

[2] Written by journalist turned filmmaker Prajesh Sen,[3] the book also presents the story of Nambi Narayanan’s life.

In his speech, Shashi Tharoor mentioned that the "Nation owes an apology to Nambi Narayanan" [8] “He chose to work for ISRO though he was invited by NASA after his education at Princeton University.

Maybe he would have risen to the post of ISRO chairman for his meritorious service, but he now survives to reveal a moving tale which is a warning to the dedicated few,” Tharoor said The preface for this book was written by T. N. Seshan.
