    CAREERS IN THE SPACE INDUSTRY

    In 1990 the Princeton Planetary Society published the first edition of
    "Space Jobs: The Guide to Careers in Space-Related Fields." The
    publication was enormously successful: we distributed 2000 copies to
    space enthusiasts across the country and even sent a few to people in
    Great Britain, Australia, and Ecuador. Due to the tremendous response to
    the first edition, PPS has published an expanded, up-to-date second
    edition of the guide.

    The 40-page publication boasts 69 listings for summer and full-time job
    opportunities as well as graduate school programs. The second edition of
    "Space Jobs" features strategies for entering the space field and
    describes positions at consulting and engineering firms, NASA, and
    non-profit organizations. The expanded special section on graduate
    schools highlights a myriad of programs ranging from space manufacturing
    to space policy. Additional sections include tips on becoming an
    astronaut and listings of NASA Space Grant Fellowships and Consortia, as
    well as NASA Centers for the Commercial Development of Space.

    SPACECRAFT MODELS

    "Space in Miniature #2: Gemini" by
	Michael J. Mackowski
	1621 Waterwood Lane, St. Louis, MO 63146
	$7.50

    Only 34pp but enough pictures & diagrams to interest more than just the
    modelling community, I feel.

    Marco's Miniatures of Dracut, Mass. have produced a 1/144 Skylab in an
    edition of 500 & a 1/48 Lunar Rover (same scale as Monogram and Revell
    Lunar Modules) in a similar edition. Prices are $45 for Skylab, $24 for
    LRV. Check with them for postage etc. I have no connection with them,
    but have found their service to be good and their stock of rare/old kits
    *is* impressive. Prices range from reasonable ($35 for Monogram 1/32
    scale Apollo CSM with cutaway details) to spectacular ($145 for Airfix
    Vostok).

    As reviewed by Bob Kaplow:

	Peter Alway's book "Scale Model Rocketry" is now available. Mine
	arrived in the mail earlier this week. To get your own copy, send
	$19.95 + $2.50 s/h ($22.45 total) to:

			Peter Alway

	V-2 (BT60), and a 1/9.16 Aerobee 150A (BT55/60).

	I've only begun to study the book, but it certainly will be a
	valuable data source for many modellers. Most vehicles include
	several paragraphs of text describing the missions flown by the
	rocket, various specs including "NAR" engine classification, along
	with a dimensioned drawing, color layouts & paint pattern, and a

    ROCKET PROPULSION

	George P. Sutton, "Rocket Propulsion Elements", 5th edn,
	Wiley-Interscience 1986, ISBN 0-471-80027-9. Pricey textbook. The
	best (nearly the only) modern introduction to the technical side of
	rocketry. A good place to start if you want to know the details. Not
	for the math-shy. Straight chemical rockets, essentially nothing on
	more advanced propulsion (although earlier editions reportedly had
	some coverage).

	Rocket Engines", NASA SP-125.
	NTIS N71-29405		PC A20/MF A01	1971  461p
	Out of print; reproductions may be obtained through the NTIS
	(expensive). The complete and authoritative guide to designing
	liquid-fuel engines. Reference #1 in most chapters of Sutton. Heavy
	emphasis on practical issues, what works and what doesn't, what the
	typical values of the fudge factors are. Stiff reading, massive
	detail; written for rocket engineers by rocket engineers.

	0-7923-0970-7 (hardback).

	    This looks at system-level design of a spacecraft, rather than
	    detailed design. 23 chapters, 4 appendices, about 430 pages. It
	    leads the reader through the mission design and system-level
	    design of a fictitious earth-observation satellite, to
	    illustrate the principles that it tries to convey. Warning:
	    although the book is chock-full of many useful reference tables,
	    some of the numbers in at least one of those tables (launch
	    costs for various launchers) appear to be quite wrong. Can be

	"Fusion as Electric Propulsion", Robert W. Bussard, Journal of
	Propulsion and Power, Vol. 6, No. 5, Sept.-Oct. 1990

	    Fusion rocket engines are analyzed as electric propulsion
	    systems, with propulsion thrust-power-input-power ratio (the
	    thrust-power "gain" G(t)) much greater than unity. Gain values
	    of conventional (solar, fission) electric propulsion systems are
	    always quite small (e.g., G(t)<0.8). With these, "high-thrust"
	    interplanetary flight is not possible, because system
	    acceleration (a(t)) capabilities are always less than the local
	    gravitational acceleration. In contrast, gain values 50-100
	    times higher are found for some fusion concepts, which offer
	    "high-thrust" flight capability. One performance example shows a
	    53.3 day (34.4 powered; 18.9 coast), one-way transit time with
	    19% payload for a single-stage Earth/Mars vehicle. Another shows
	    the potential for high acceleration (a(t)=0.55g(o)) flight in
	    Earth/moon space.

	"The QED Engine System: Direct Electric Fusion-Powered Systems for
	Aerospace Flight Propulsion" by Robert W. Bussard, EMC2-1190-03,
	available from Energy/Matter Conversion Corp., 9100 A. Center
	Street, Manassas, VA 22110.

	    [This is an introduction to the application of Bussard's version
	    of the Farnsworth/Hirsch electrostatic confinement fusion
	    technology to propulsion. 1500<Isp<5000 sec. Farnsworth/Hirsch
	    demonstrated a 10**10 neutron flux with their device back in
	    1969 but it was dropped when panic ensued over the surprising
	    stability of the Soviet Tokamak. Hirsch, responsible for the
	    panic, has recently recanted and is back working on QED. -- Jim
	    Bowery]

	"PLASMAKtm Star Power for Energy Intensive Space Applications", by
	Paul M. Koloc, Eight ANS Topical Meeting on Technology of Fusion
	Energy, special issue FUSION TECHNOLOGY, March 1989.

	    Aneutronic energy (fusion with little or negligible neutron
	    flux) requires plasma pressures and stable confinement times
	    larger than can be delivered by current approaches. If plasma
	    pressures appropriate to burn times on the order of milliseconds
	    could be achieved in aneutronic fuels, then high power densities
	    and very compact, realtively clean burning engines for space and
	    other special applications would be at hand. The PLASMAKtm
	    innovation will make this possible; its unique pressure
	    efficient structure, exceptional stability, fluid-mechanically
	    compressible Mantle and direct inductive MHD electric power
	    conversion advantages are described. Peak burn densities of tens
	    of megawats per cc give it compactness even in the
	    multi-gigawatt electric output size. Engineering advantages
	    indicate a rapid development schedule at very modest cost. [I
	    strongly recommend that people take this guy seriously. Bob
	    Hirsch, the primary proponent of the Tokamak, has recently
	    declared Koloc's PLASMAKtm precursor, the spheromak, to be one
	    of 3 promising fusion technologies that should be pursued rather
	    than Tokamak. Aside from the preceeding appeal to authority, the
	    PLASMAKtm looks like it finally models ball-lightning with solid
	    MHD physics. -- Jim Bowery]

    ION DRIVES:

	Retrieve files pub/SPACE/SPACELINK/6.5.2.* from the Ames SPACE
	archive; these deal with many aspects of ion drives and describe the
