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
This week there was a bit of a political kerfuffle during House hearings over a House report [pdf] that stated that the cost per pound for launching cargo to ISS was much cheaper using the shuttle versus the new commercial companies under the COTS program. This is shown in this table from page 5 of the report:
The problem is that these numbers are a complete lie, as they are based on a yearly cost of $3 billion to operate the shuttle (highlighted in yellow). I have been following NASA budget battles now for decades, and the shuttle operational budget has never, ever been that low. Routinely, NASA figures the cost to operate the shuttle per year, regardless of number of flights, to be about $4 billion per year.
Thus, the numbers announced by this House report are garbage. They have intentionally underestimated the launch cost for the shuttle by 25% in order to make the COTS program look overpriced. If you instead use the more reasonable $4 billion per year number for shuttle operations (which in itself is still a lowball estimate) you get a cost per pound for the shuttle of $28,357, which is actually larger than the estimated cost of $26,770 per pound for COTS.
Nor does any of this take into account the long term likelihood that companies like SpaceX will eventually be able to lower their costs further, once research and development is complete, the engineering becomes less experimental and more robust, and they start to take advantage of economies of scale by selling more launches to more customers. With these factors in place I have great confidence they will then be able to beat the Russians in price.
The per pound cost for the shuttle, however, will never go down, under any conditions.
I suspect this House report was fudged in this manner as a political move to bolster support for building the program-formerly-called-Constellation, a government-built rocket and capsule that helps bring jobs to Congressional districts. It is for this reason I haven’t paid much attention to it. However, one of my regular readers emailed me to complain about my lack of comment on this subject (Hi Kelly!). Also, I will be discussing this on the Space Show on Monday, Thus I decided this subject deserved comment.
The report does note some legitimate areas of concern in connection with NASA’s effort to transfer its launch capabilities from a government-run system (the shuttle) to private suppliers. At the top of those concerns is the unproven nature of these companies. Without question the Obama administration is taking a big gamble by taking this route.
Moreover, despite the fact that I have been a very big cheerleader for SpaceX over the past five years, I do wonder why SpaceX has not launched any of additional commercial satellites on its Falcon 1 rocket since its second launch (the first successful commercial launch) in July 2009. Back in October 2008 after Falcon 1’s first successful test flight, Elon Musk wrote that he expected to follow up this success with many more flights. “Flight 6 will probably be a Defense Department satellite in the summer [of 2009] and Flight 7 a commercial satellite mission in the fall [of 2009]. In 2010, I expect the launch cadence for Falcon 1 to step up to a mission every two to three months.”
None of these launches ever occurred. And the launch manifest on the SpaceX webpage only says that the multiple Falcon 1e launches of the Orbcomm constellation of 12 satellites will supposedly begin sometime this year. When, however, remains unclear.
It would be help ease the doubts of many people, including myself, if SpaceX started to fly these rockets, as promised, on a regular commercial basis.
