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

Behind The Black, c/o Robert Zimmerman
P.O.Box 1262

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

Also available as an inexpensive ebook!

Leaving Earth: Space Stations, Rival Superpowers, and the Quest for Interplanetary Travel, can be purchased as an ebook everywhere for only $3.99 (before discount) at amazon, Barnes & Noble, all ebook vendors, or direct from my ebook publisher, ebookit.

"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.

    I’m from around Chicago.

    … this does not surprize. Remember ni the 60’s when they draged the leed NBC news anchor off the floor of the dem national convention and arrested him, WHILE HE WAS ON THE AIR because he said some things the mayor didn’t like?

  • Chris Kirkendall

    Yep – that was old Mayor Daley, Rich Daley’s Dad. Not much has changed – I live in the Chicago area & the corruption is just staggering. In one of the recent primaries for a Congressional seat, a Dem who was just CONVICTED of bribery got 77% of the votes in his district ! ! It’s been incredibly warm here for over a week, low & mid 80s & there’s been a rash of violence, 49 shootings & several deaths just in the last few days – I’m ashamed & embarrassed – we’re becoming Detroit (no offense to any Detroiters who are equally appalled at what their city has become). This is what you get when you have a Democrat Machine-controlled city, and Cook County is totally controlled by the Dems, as well as the State of IL – all drowning in massive debt, taxes going thru the roof, crime, and corruption. I warned people about Obama – told them this is what you’re gonna get, because he’s right out of this culture of corruption. Not enough listened…

    I could have just seen it in a history class — yeah thats it!!


  • Kelly Starks

    Fear not. Detroit is much worse….They’ve lost almost a third of the metro population, adn large areas of the city are being taken over by wildlife (Dear hunting in the abandoned nieghborhoods?!!

    Of course humans are the favority prey there.

    Yeah, I do get tired of voters voting in such corrupt destructive fools.

    Me too! And my grandfather told me all about it!!!!
