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!

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

The Democrats in the Senate have passed their tax plan.

The Democrats in the Senate have passed their tax plan, extending the Bush tax rates for families making under $250,000 for one year while allowing the rates for families earning above $250,000 to expire.

The big Democratic claim has been that in order to balance the budget richer people have to pay more of their fair share. Okay, so now they’ve made their point by law. If I were the Republicans I’d accept it, since we all know that this tax increase on higher income taxpayers will do nothing to lower the deficit. We could raise the tax rate for anyone earning more than $250K to 100 percent and we would still have a gigantic yearly deficit.

What will the Democrats next claim when this tax increase fails? It won’t matter. The problem is spending, and the failure of this tax plan will further demonstrate that point. The federal government has to learn to live within its means.

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.

    “The federal government has to learn to live within its means.” (thats an understatement)

    This will never and can never happen until the people through their will shift the power in the government one way or the other.

    That, hopefully will happen this November.

    Thats when there will be Bi partisanship, one party gains power and a majority and through logic, need and persuation a percentage of the

    other side joins with them.

    Thats the real definition of Bi partisan in politics.

    I agree. This would go a long way to taking “pay their fair share” right off the table and yet $1t deficits would still be an issue during the election.
