Will I be Writing a Book About JWST?

With Dr. Robert W. Smith (l) in 2011.

Since the successful launch of the James Webb Space Telescope (JWST) on December 25, a few people have asked if I will be a writing a book about JWST to follow my recently published book, Not Yet Imagined: A Study of Hubble Space Telescope Operations (NASA, 2021).

The answer is no, and there is a story behind that ‘no.’

There is an excellent book on JWST being written by Dr. Robert W. Smith, who also wrote the classic study of how Hubble was conceived and built, a process that also took decades. His book on Hubble, The Space Telescope, A study of NASA, science, technology and politics, was first published in 1989, before Hubble was launched, and an updated paperback version was published in 1993.

His book contains many insights on how astronomers overcame divisions within their ranks to win government approval for Hubble, and then it outlines the work that went into building this space observatory.

Since it explained one of the most prominent space programs of its time, I purchased Dr. Smith’s book for my library when it came out and read it with great interest. Dr. Smith was based at the National Air and Space Museum and Johns Hopkins University when he wrote that book, and he later moved to Edmonton, Alberta, where he became chair of the Department of History and Classics at the University of Alberta.

As the new century began, I had written my first book of space history, Arrows to the Moon: Avro’s Engineers and the Space Race (Apogee Books, 2001), and I decided to earn a master’s degree in space studies at the University of North Dakota. When I completed that degree I decided to pursue further studies, and a promising avenue appeared at the University of Alberta.

I visited Dr. Smith in 2003 to inquire about studying the history of technology with him as my faculty advisor. I remember that he encouraged me to pursue studies for a Ph.D. That day we also discussed plans for a gigantic new space telescope that had just been named after the late NASA administrator, James Webb.

I spent the next few years on my Ph.D. studies, benefitting from Dr. Smith’s guidance and the many insights he had gained about Big Science projects such as the Hubble Space Telescope. By then, Dr. Smith had begun closely following the development of JWST, and I occasionally helped him with that work as graduate students often do.

My own Ph.D. studies focused on the years between World War II and the beginnings of the space race between the United States and the Soviet Union in the late 1950s. That resulted in my dissertation, which became a book, The Bomb and America’s Missile Age (Johns Hopkins, 2018).

After I completed my dissertation, NASA was looking for someone to write a history of Hubble operations. Since Dr. Smith was working on his JWST book, he was unavailable for that project. Although I had not previously thought of writing a book about Hubble, I was available. With Dr. Smith's encouragement, I competed for that job and was selected in 2014 to write the book that covers the first three decades of HST operations. While writing that book, I received a great deal of helpful advice from Dr. Smith.

While at NASA's Goddard Space Flight Center as I conducted research for my Hubble book, I regularly looked in on JWST, which was being assembled in a gigantic cleanroom there. JWST appears in my book, and scientists hope to coordinate obervations between the two space telescopes once JWST begins operations.

Both the Hubble and Webb telescopes are highly expensive and complicated, and both underwent challenging development processes before they got to their launch pads. The pre-launch history of JWST goes back more than two decades, so Dr. Smith’s upcoming book will be a substantial one. I don’t know the title yet, but I am looking forward to reading it when it is published.

I hope to write at least one more book to add to the six I have already written. I haven’t settled on a topic, but I have been keeping busy during the pandemic writing papers on the history of space astronomy in Canada.

Not Yet Imagined: A Study of Hubble Space Telescope Operations

The Hubble Space Telescope (HST) is the most famous astronomical instrument of its time and one of the best-known robotic vehicles ever put into space. Its launch and deployment into low-Earth orbit from the Space Shuttle Discovery in April 1990 appeared to fulfill the plans and dreams of astronomers since the beginnings of space exploration to place a telescope beyond the distorting effects of Earth’s atmosphere.

The first images from Hubble contained a stunning surprise: the space telescope’s main mirror had been precisely ground to the wrong shape. With the future of NASA on the line, scientists and engineers devised fixes for the spherical aberration afflicting Hubble, and astronauts flying on the first of five shuttle servicing missions to HST installed new instruments that restored the space telescope’s capabilities. Within weeks HST produced the breathtaking images and other data that astronomers and the public had long anticipated, and Hubble went on to become a symbol of American technological and scientific prowess.

My latest book, Not Yet Imagined: A Study of Hubble Space Telescope Operations, has been published by the NASA History Division. Its e-book versions are available for free download at https://www.nasa.gov/connect/ebooks/not-yet-imagined.html. Free hard copies of this book are available from the NASA Information Center, info-center@hq.nasa.gov, 202-358-0000, Suite 1U72, NASA Headquarters, Washington, DC 20546. One per customer please.

This book documents the history of HST from its launch through its first 30 years of operation in space. It focuses on the interactions among the general public, astronomers, engineers, government officials, and members of Congress during that time. The decision-making behind the changes in Hubble’s instrument packages on servicing missions that made HST a model of supranational cooperation amongst scientists is chronicled, along with HST’s contributions to our knowledge about our solar system, our galaxy, and our universe. Not Yet Imagined also covers the impact of HST and the images it produces on the public’s appreciation for the universe, and how HST has changed the ways astronomy is done.
