Guest: Robert Zimmerman was the guest for this program to discuss his new book about the Hubble Space Telescope (HST), "The Universe In A Mirror: The Saga of the Hubble Space Telescope and the Visionaries Who Built It." This is an excellent book, a must read for those of you who want to know more about the HST. Having read the book and after talking to Bob, it's easy to realise that there is still much to learn about HST's history, from CCD cameras to mirrors and NASA contracting. The information in the book about the mirror error and how it got so far through the system is fascinating.
