Chronological Encyclopedia of Discoveries in Space cover

After being in print for twenty years, the Chronological Encyclopedia of Discoveries in Space, covering everything that was learned on every single space mission in the 20th century, has finally gone out of print.

 
I presently have my last four hardback copies available for sale. The book sold new for about $90. To get your own autographed copy of this now rare collector's item, please send a $120 check (which includes shipping) payable to Robert Zimmerman to

"Useful to space buffs and generalists, comprehensive but readable, Bob Zimmerman's Encyclopedia belongs front and center on everyone's bookshelf." -- Mike Collins, Apollo 11 astronaut

 

"The Chronological Encylopedia of Discoveries in Space is no passionless compendium of information. Robert Zimmerman's fact-filled reports, which cover virtually every spacecraft or probe to have ventured into the heavens, relate the scientific and technical adventure of space exploration enthusiastically and with authority." -- American Scientist

An evening pause: More proof that modern engineering can make almost anything seem easy.

Hat tip Phill Oltmann.

    Thats an awful big and complex machine, way up high, and a lot of guys all depending that nothing fails, like the grade of concrete being poured in those columns by some Chinese contractor. Its cool, but it makes me nervous.

    Look on the bright side: if it doesn’t collapse during the erection, you’d feel safe driving a car over it when it’s done.

    It would be even cooler if they could do this on a curved section.

    Not a safety harness in sight. Here in BC the authorities would poop nukes. Send in the grief counsellors.

  • I agree about the safety measures. One thing I’ve noticed about Chinese construction practices is that little attention is paid to worker safety. But when you’ve got 2 billion people to choose from, and the State protects you from liability, why worry? On the other hand, I was looking at the process from a continuous feed standpoint, sort of like a TBM.
