Subject: Commercial Space News #18 [Part 2]
Newsgroups: sci.space
Glavkosmos have claimed these sanctions are more driven by
commercial considerations by the US, with Kumaramangalam claiming
"U.S. objections to the sale of cryogenic engines for Indian rockets
by Russia was purely due to commercial considerations".
This imbroglio has caused some real mudslinging and trading of
accusations and insults, and it is my opinion this issue has been
handled badly by the US State Department and the Russian government.
Also in response, the Indian government has been searching for
alternative sources of supply for US-provided components which were
used by ISRO in the Indian space activities. Apparently, India has
approached several countries including China and France to provide
equivalent components. However, during a recent visit to France by
Indian Prime Minister Narasimha Rao, the government of France stated
they would not approve any export licenses for space technology for
India. Specifically, the French Government insisted India sign the
MTCR before any space technology could be legally exported.
Once these trade restrictions are lifted (and they are only for a
2 year period), Indian space technology will find a ready market for
some of their ingenious low-cost methods of applying space
technology. Capturing 1 percent of the worldwide space activities
budget (which my my estimate is about $45,000 M, not including
Chinese or Russian activities), would be about $450 M a year in
annual sales, which is substantially above the Indian national space
budget. Looking just at the commercial market however (which I
estimate at about $8,000 M), would represent about $80 M per year,
and is probably achievable by the Indian industry and would
substantially boost Indian space activities.]
FINAL NOTES - Commentary
As I stated in the preface, this column seems to be largely
influenced by changes occurring as ex-Soviet space systems are put
into the market. I've been seeing a lot of activities with ex-
Soviet space systems, but only now have the potential of significant
impacts on the commercial space marketplace started to surface.
These ex-Soviet systems can have a significant impact on the
commercial market place as ex-Soviet capabilities are being sold at
fire sale prices. Some near term offerings that are appearing seem
to just be selling off surplus government-developed assets at
minimal costs to obtain hard currency cash flow, offering of ex-
government systems at VERY low prices to keep "national assets" in
existence, and trying to find commercial sponsors for ex-government
operations. These are not necessarily positive influences on the
market.
While the use of some of ex-Soviet space systems may offer a
quick boost to some near-term space activities by allowing a quick
expansion of cheap capabilities, these same systems can have a long-
term negative impact on commercial space ventures. This is
particularly dangerous if government-subsidized CIS space ventures
are not tested in the furnaces of the financial and business market
places and they are used to drive commercially-funded Western
ventures out of the market.
Conversely, ex-Soviet space hardware and expertise can offer
substantial benefits to commercial space activities. The
application of new techniques, new capabilities, and a hoard of
expertise and technologies can substantially benefit commercial
activities by expanding markets and opening up new applications for
commerce.
Furthermore, in my opinion, the commercial space markets offer
the best means to transition programs from the crumbling base of CIS
state sponsorship to a sound financial and market base. This
transition will not go easily or without problems, but commercial
sponsorship of ex-Soviet systems can provide an expanded base of
sustainable expertise and techniques that can be used to grow the
industry.
What we have to guard against is the propping up of unprofitable
ventures for short-term political gain at the expensive of long-term
commercial opportunities. Yes, it is probably prudent to provide
Western government support to ease this transition -- but it must be
done always with the eventual goal of realistic market pricing and
self-sufficency, which is a far cry from carving out a new "quota"
for Russian launches and systems.
But that's enough flame on this topic.
This issue turned out to be rather longer than I expected. I
hope the net will indulge me on this, but the backlog of data and
other activities only seems to get worse each month. I'm trying to
decrease my cycle time in turning out issues by being more
systematic about turning data into column articles, so that's
helping a little bit with the data deluge. I'm also turning out a
small limited press run of hardcopy versions of these columns.
And as always, I hope you folks find this stuff useful and
interesting -- Any and all comments are welcome.

WF/PC and the fine guidance sensors are arranged around the light path --
with pickoff mirrors directing part of the image into them -- just ahead
of the four big instruments. Essentially, there's a ring of equipment
around the light path, divided into four quadrants, three for the FGSs
and one for the WF/PC.

To the best of my knowledge, the only statement in my posting which is
not a solidly-established fact -- verifiable by reference to the Allen
panel's report -- is my opinion that P-E management, having ignored two
indications of trouble (actually three, if you count the fact that the
reflective null corrector unexpectedly required extra spacing washers),
would have disregarded the results of other simple tests too, unless
they were absolutely unmistakable (i.e. an end-to-end imaging test).
If I am in error -- certainly possible -- I'd appreciate hearing about
it, preferably with enough detail so I can verify it.

Subject: Lunar "colony" reality check, part 2
Newsgroups: sci.space,alt.sci.planetary
Lunar "colony" reality check, part 2:
* The claim that solar energy will be so cheap on the moon as
to be an advantage, is absurd. A lunar site spends a
half-month long stretch every month out of sunlight.
Solar cells are not economical for most uses on earth
and would cost far more to transport on the moon. Making
them on the moon is even more absurd, see following comments
on industrial capabilities.
* Lower launch costs benefit all large space operations, from
DBS to comet mining. Lunar bases do require a much larger and
more improbable fall in launch costs than dozens of other
space development activities which would actually make money.
* In addition to hydrocarbons or polymers, urea is a good
bulk way to supply lunar operations with essential volatiles
from earth. However, these schemes require huge ongoing launches
from earth. They require large-scale, messy, difficult to maintain
chemical plants designed for 1/6 g, as does the cracking of oxygen
from lunar regolith.
* The industrial environment on the moon is vastly inferior to that
on earth, and to that in space where there is microgravity,
high-grade metal regolith and abundant volatiles. The energy
and thermal environment of the moon, as well as the lack of cheap
volatiles, makes it an extremely poor place for chemical
and industrial operations.
* Just as with Shuttle, astronauts will not be able to fix most
broken equipment. Most disabling breaks, no matter to how
small a part, will require an entire replacement unit to be
shipped from earth. Since the astronaut's very lives will
depend on recycling equipment, large numbers of spares will
have to be shipped on the first trip.
* Redesigning equipment for 1/6 g will cost _more_ than
redesigning it for 0 g, because the latter has been
done for a much wider array of equipment on satellites
& stations.
* Unlike the intrepid Biosphereans, lunar astronauts will
not be able to cheat and come back to civilization to
find good medical care. In a lunabago will be found
little more than a part-time doctor and a first-aid kit.
* There are no "resources" on the moon that could not be
provided at lower cost from asteroids or comets, and the
most important materials like volatiles and high-grade
metal regolith are available only from the planetesimals.
* Transport costs to the moon are six orders of magnitude
greater than transport costs to the North Slope. Not only
Ed's toilet paper but also the recycling equipment, spares,
and volatiles (if brought from earth) will make the cost of
supporting astronauts at least six orders of magnitude more
expensive than the cost of hosting a worker at the North Slope.
It should be noted that no families have permanently relocated
to the North Slope; even the industrial workers themselves
commute by airplane rather than live without their families for
years on end.
* Submarines get to surface every month or more, and can come back to
port for food & sex. Nobody has a "submarine colony", even though
it would be far less expensive and more functional than a lunar
"colony".
* If scientific knowledge is an "economic resource", then what
happened to NASA's planetary science budget? Why can't they
even find money for a lunar polar orbiter, which costs many
orders of magnitude less than even a minimal lunar base?
Why not let scientists decide where to spend the science budget?
(Hint: lunar base isn't even _on_ their long list of priorities).
* Microgravity manufacturing, large platforms and other space
industries could export $10's of billions per year to earth
by using a large supply of cheap volatiles and high-grade metal
regolith, available in abundance from planetesimals but absent
on the moon. With low thrust in microgravity, the power needed
to move this material to earth orbit is orders of magnitude less
than needed to get useless lunar material out of the moon's gravity
well.
Our obsession with the Death Valley in front of us continues
to blind our eyes to the fertile valleys beyond, and the space
colonization movement remains mired in failure.

NO. AMBLER and DANTES have entirely different missions. AMbler was a test bed

Subject: New engines for NLS/ possible for shuttle?
Newsgroups: sci.space
saw something that for the NLS proposal, they want to use something
called the Space transportation Main Engine, which will have 1/10th
the parts count and three times the thrust of SSME's.
has anyone looked to see if these could replace the SSMEs???
i imagine they would drastically reduce the service costs of
the shuttle and improve reliability. Are they compatible
or are the design frames way different?

What about the SSTO DC-Y? It's my understanding that the DC-1 should be
able to do just about everything that the shuttle can do (with the possible
exeption of carry the SpaceLab). And a lot cheapter to boot.

I agree wholeheartedly with that last statement, but I still believe that
removing commercial and non-Shuttle-unique payloads from the Shuttle was a
good idea. As I explained in my previous post, the Shuttle is a very unique
and versatile vehicle. It has tremendous capabilities no other vehicle can
touch, but it can only fly eight times a year. In that situation, using it
to do things that can easily be done on other vehicles (e.g. launching spy
or commercial satellites) is a waste of a valuable resource. The Shuttle
should be used exclusively for missions like the Hubble revisit, the Intelsat
satellite rescue, Tethered Satellite System, International Microgravity Lab,
Wake Shield Facility, etc. There are no shortage of payloads to fly. NASA
has no flight opportunities and less than a half dozen payload opportunities
between now and the start of Space Station operations.
According to the mission control status briefings, the astronauts were working
12 to 16 hour days. Payload volume may not have been the active constraint
for STS-52.

The cooling issue is a serious one. Apollo didn't have that concern --
since doing an EVA required depressurizing the entire cabin, air-cooled
equipment could not be used at all. This was okay, more or less, for
Apollo, but simply isn't appropriate for a laboratory environment:
air cooling is by *far* the easiest way to cool electronics, and the
cost of the hardware goes way up without it.
And yes, there is some concern about possible long-term biological
effects, although there is little firm knowledge.

*Rate for a three-day conference.
**There is no separate registration rate for the SETI conference.
Attendees for the SETI conference will have to pay for two days. If
you can spare the time, attendees are recommended to take in the
Wednesday morning and afternoon, and Thursday morning sessions of the
Free-Space Laser Communication Technologies V conference, as this
technology is very relevant to Optical SETI. The cost for the full
conference period (three days) is little more than for the two day OSETI
conference alone.
SPIE Proceedings Volume 1867 $ 35
These proceedings will also include a copy of Dr. Lesh's large
review paper on NASA's optical communications activities, which is to be
presented at the Free-Space Laser Communication Technologies V
conference.

Subject: Weekly reminder for Frequently Asked Questions list
Newsgroups: sci.space,sci.astro,sci.space.shuttle
This notice will be posted weekly in sci.space, sci.astro, and
sci.space.shuttle.
The Frequently Asked Questions (FAQ) list for sci.space and sci.astro is
posted approximately monthly. It also covers many questions that come up on
sci.space.shuttle (for shuttle launch dates, see below).
The FAQ is posted with a long expiration date, so a copy may be in your
news spool directory (look at old articles in sci.space). If not, here are
two ways to get a copy without waiting for the next posting:
(1) If your machine is on the Internet, it can be obtained by anonymous
FTP from the SPACE archive at ames.arc.nasa.gov (128.102.18.3) in directory
pub/SPACE/FAQ.
(2) Otherwise, send email to 'archive-server@ames.arc.nasa.gov'
containing the single line:
help
The archive server will return directions on how to use it. To get an
index of files in the FAQ directory, send email containing the lines:
send space FAQ/Index
send space FAQ/faq1
Use these files as a guide to which other files to retrieve to answer
your questions.
Shuttle launch dates are posted by Ken Hollis periodically in
sci.space.shuttle. A copy of his manifest is now available in the Ames
archive in pub/SPACE/FAQ/manifest and may be requested from the email
archive-server with 'send space FAQ/manifest'. Please get this document
instead of posting requests for information on launches and landings.
Do not post followups to this article; respond to the author.

Subject: Where are shuttle research publications?
Newsgroups: sci.space
I do not know any specific journal that publishes only Shuttle
Research but I do remember of having seen an issue of Science
describing the research done during the Spacelab-1 mission (do not
remember the issue number but, for sure, it was published after the
mission). It was a very comprehensive article and I recall that some of
the authors were Bob Parker and Owen Garriott (crewmembers of the
Spacelab mission).
May be another way of finding out research articles of experiments
performed during a Shuttle mission, would be to try to get one of
these NASA booklets that are published just before a mission or even
the NASA Press Kit of the mission itself. These publications include
the name of the PI's and the experiments that are going to fly. By
knowing at least the name of the PI you can later on make a literature
search using the name of the PI and then get the article about the
experiment that flew in the Shuttle.
Another way to find out about that would be to contact anyone at
University of Alabama in Huntsville. They have a lot of people there
that fly experiments in the Shuttle and, for sure, they must have
articles published in scientific, archival journals.
