Born to Explore – John Casani’s Grand Tour of the Solar System by Jay Gallentine; Nebraska Press; 400 pages; Hardcover, $39.95.
This fascinating read centers on one of the most valued leaders that worked for the Jet Propulsion Laboratory and managed a slew of NASA projects, including Voyager, Galileo, and the Cassini mission to Saturn.
For those that had their own close-encounter with John Casani – as this reporter did several times – he was a tour-de-force of facts, enthusiasm, and stick-to-it management guidance.
Jay Gallentine, an award-winning space historian from Minnesota, has written an absorbing look at this legendary leader that rose through JPL’s ranks to a senior executive.
As the author skillfully notes, Casani battled politics, funding issues, the laws of physics, and also on occasion his JPL compatriots. “We didn’t know how to do what were supposed to do. We were too dumb to know that what they were askin’ us to do would really be hard,” said Casani on his early days at JPL as cited by Gallentine.
Casani harbored a persistent drive to undertake some of the most momentous – and nine-figure space missions — ever embarked upon.
Sadly, John Casani passed away on June 19, 2025 at 92 years of age – and did not see the publication of this masterfully written volume.
So often, we space cadets herald the hardware of space victories in far off corners of our solar system. These are legacy successes made possible by individuals that accept and confront challenges like no other.
But thanks to Gallentine’s account through the book’s 27 chapters, the reader can appreciate the expertise Casani brought to America’s adventurous, ambitious and audacious space exploration program. It is an outstanding story told and a significant entry in the Nebraska Press Outward Odyssey series.
