Leaving Earth cover

In 2019 I obtained from my former publisher the last 30 copies of the now out-of-print hardback of Leaving Earth. I sold about half of these, and with only a handful left in stock I have raised the price. To get your own autographed copy of this rare collector's item please send a $75 check (includes $5 shipping) payable to Robert Zimmerman to

"Leaving Earth is one of the best and certainly the most comprehensive summary of our drive into space that I have ever read. It will be invaluable to future scholars because it will tell them how the next chapter of human history opened." -- Arthur C. Clarke

Pioneer cover

From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.

Unfortunately, that is exactly where that journey takes him.

The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.

He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

    Wonderful story. Just an objection that CBS news says the American soldiers risked their lives to help the Russians. No doubt the Germans were brutal toward the Russians. But were any American POWs killed for attempting to get food to their Russian counterparts? In general, I cannot think of any reports of American POWs being executed by German captors.

  • Yes, an amazing story! Thanks for sharing.

    I’m certain there are more.

    There was also the infamous Malmedy Massacre of American prisoners by the German SS during the early phases of the Battle of the Bulge. These were all freshly-taken prisoners who never survived long enough to be incarcerated in a camp.

    Hitler also issued a general order in the middle of the war to the effect that any enemy commandos/special operations troops captured were to be summarily executed. This order was carried out on numerous occasions thereafter.

    “Saints and Soldiers”

    “Saints and Soldiers is a 2003 war drama film directed by Ryan Little and produced by Little and Adam Abel. It is loosely based on events that took place after the Malmedy massacre during the Battle of the Bulge. The film stars Corbin Allred, Alexander Niver, Lawrence Bagby, and Peter Asle Holden as the four American soldiers trying to return Kirby Heyborne, a British soldier with vital intelligence, to the Allied lines.”

    You need to read T.D. Calnen‘s book ”Free as a running fox“. He tells all about tunnelling, escaping as well as helping Russians. Great read!
