His most recent book is on the origins and evolution of ideas about space exploration in Russian and Soviet culture. The book, entitled The Red Rockets' Glare: Spaceflight and the Soviet Imagination, 1857-1957 (Cambridge University Press, 2010), is based on extensive archival research in Russia, and is the first academic work on the birth of Sputnik.
His first book was the two-volume Sputnik and the Soviet Space Challenge and The Soviet Space Race with Apollo both published simultaneously by the University Press of Florida in 2003. These volumes, dealing primarily with events during the Cold War, were the first histories of the Soviet space program based on Russian sources available after the collapse of the Soviet Union. Originally published as a single volume, Challenge to Apollo: The Soviet Union and the Space Race, 1945-1974 by the NASA History Office, the book has received numerous national awards. In their December 30, 2006 issue, the Wall Street Journal named it one of the five best books ever published on space exploration.
He is currently working simultaneously on two book projects. The first is a history of the Indian space program grounded in the broader context of postcolonial science, technology, and modernity. A second book project is on the relationship between science and technology and repression. Using the Soviet case as a starting point, he plans to explore the historical role of repression (coercion, arrest, incarceration, execution) in the practice of science and engineering in the twentieth century.
Dr. Siddiqi is also serving as Series Editor of the four-volume English language memoirs of a Russian rocket engineer, Boris Chertok. These volumes are being published under the general title Rockets and People. So far, three volumes of Rockets and People have been published, Vol. I (NASA History Division, 2005), Vol. II: Creating a Rocket Industry (NASA History Division, 2006), and Vol. III: Hot Days of the Cold War (NASA History Division, 2009)
He has published widely on the history of technology and modern Russian history in the following journals: Technology and Culture, Osiris, History and Technology, Europe-Asia Studies, Georgetown Journal of International Affairs, Acta Astronautica, and Voprosy istorii estestvoznaniia i tekhniki.
