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!

Winner of the 2003 Eugene M. Emme Award of the American Astronautical Society.

"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

The Starbugs – Mr Tambourine Man

An evening pause: Sung by Jessie Hillel, Sarah Whitaker, Roisin Anderson, Ben Anderson, Rebecca Jenkins. From the youtube page: “We have re-pitched this captivating selection of favourites to suit children’s voices.”

Truly one of Bob Dylan’s most beautiful and poetic songs.

Hat tip Tom Biggar.

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.

    IMO, Creepy Kids.

    Jerry Jeff Walker did not Mr. Tambourine Man. Bob Dylan did.

  • Tom Biggar


    Everything I have cites Dylan as the author of Mr Tambourine Man. Perhaps you are thinking of Mr. Bojangles, which Jerry Jeff wrote?

    I‘ve always liked the Byrds‘ version.

  • Tom

    You are correct. My mistake.

  • Col Beausabre

    IIRC, the Byrds cut their version before Dylan released his,

    (Yes, I was right. “The Byrds version is based on Bob Dylan’s demo of the song that he recorded during sessions for his 1964 album Another Side of Bob Dylan (Dylan’s version was not yet released when The Byrds recorded it))

    but had to hold up on their release due to technicalities in how licensing works.

    It’s called “Mechanical License” and it states that once you release a song, anyone is entitled to perform it as long as they pay the statutory licensing fee.

    “The song must have already been recorded and distributed by the copyright owner. Another way this is stated is that the copyright owner gets “first use” of their creation. Note that the copyright owner has to be the one who recorded it; if someone else steals their work and records it, that doesn’t qualify as “previously recorded.” Also, recording it is not enough. The copyright owner has to have made it available for public consumption.”
