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

Today I am doing a two hour appearance, from 6:00 to 8:00 pm (Eastern), on the podcast Task Force Gryphon on Kgra Radio.

First time with this show. I expect it should be different because of this.

    Off topic: Wayne, Jordan Petersen, depression, drugs, goes to Russia to recover, comment?

    Yeah– I’ve been trying to keep up with those developments, and saw that video recently.
    Apparently— the good Doctor was stressed outa his mind with his wife’s cancer-scare last year, and he started taking Klonopin, which is the trade-name for clonazepam, a fairly potent and long-acting benzodiazepine derivative. When he started cutting down he experienced a nasty case of rebound anxiety and fell apart.
    –By and large, benzodiazepines are very safe, however one does not want to become dependent upon them (physically or psychologically)—detox is a hospital thing, cuz’ it can kill you dead. (worse than barbiturates and heroin) I do not know what dose he was taking but I’ve seen people on 15-20mg a day, for months at a time. (the thing is— these meds are only approved for short-term use and they stop working after 4-8 months, and which time you want a lengthy drug-holiday to reassess your need and monitor your physical dependence. Concurrently, they are physically addictive and that generally leads to dose escalation, at which point you’re getting in deeper than you want to be.
    (caveat– I’m not a medical Doctor and they don’t let me prescribe meds— that being said, I personally would have advocated for judiciously low doses of time-released Xanax, or Ativan — they induce relatively less euphoria than other benzo’s, which helps with psychological dependence.

  • wayne

    no clue on the Russia angle.
