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

I will likely raise the price again when only ten books are left, so buy them now at this price while you still can!

"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.

    Not really. It just this week posted $1.5B in profits for the third quarter, or $0.89 return on a share. Analyst expectations were 60 cents a share. By the way, its the 11th straight QUARTER that it has posted profits. Any weakness in its financial report, which is hard to find, is due to Europe sales, which is down for all firms including Ford. Hardly a company looking to go bankrupt.

    The same thing that brought GM down in the first place was NOT corrected by the Obama buyout.
    Union healthcare coverage and retirements.
    Obama just stuffed cash into the union coffers.
    Inside 10 years they will have the very same problem they had before the buyout.

    Ford fixed this problem by paying (3 billion) the union itself to take over the retirements and healthcare coverage or its members.
    Now the union is crying that they will have to cut back on those very same retirements and healthcare coverages or raise rates on the members.

    GM could have made the same deal but the union did not agree and before they would have been forced into it Obama stepped in to “save” them.

    I bet Obama in this term will either dump more cash into their system or will offer to take over the retirements and force all the members into Obama care.
