Long-term survival of the species…

>>I wonder sometimes whether there may not be too many more generations
>>whose societies will be capable of sustaining space flight. Let’s not dawdle.

>IMHO, such shallow pessimism is often just a projection of one’s own

  I agree with teh origional sentiment. The world quality of life has been
going down steadily since the seventies. The funds availbale to government
space have been dropping steadily, and quickly.

  We are losing the capability to go into space. If we don’t act soon, we
will lose that capability forever.

  The government is already unable to mount a return to space. Private
enterprise is the last hope; if it fails, the species is doomed to
extinction.

  Civilisation will colapse and never return to previous heights. Our
species will go extinct and leave a planet depleted of resources, making
any other, later, intelligences unable to open space.

  That’s why I’m spending so much time trying to make the Artemis Project
happen. Artemis is essential for commercial development of space, and
commercial development of space is essential for the opening and
colonisation of space, on which rests nothing less then the long-term
survival of the species.

  Keep in mind that, to the best of our knowledge, we are the only
intelligence in the Universe. It is very important that we keep it from
passing into oblivion.

Big LEOs shakes down; global broadband heating up

1. Big LEO.

Well, it looks like we know pretty much what the current round
(1996-1999 or so) of Big LEO communication satellites will be:

a.  Iridium.  First launch in November according to the OCST manifest
dated August 2.

b.  Globalstar.  They are rapidly signing the deals with telcos which
they need, building hardware, etc.  First launch in July 1997
according to same manifest.

c.  One or both of ICO and Odyssey (MEO).  Odyssey is suing ICO over
TRW’s patent on certain orbits.  Neither due to launch until 1999.

If all four are built, this is the "high growth" scenario from the
1996 OCST report; if only three are built is the "modest growth"
scenario".  Apparently not making progress: Constellation, Ellipso.
Question marks: Signal and AMSC (listed in OCST report but I haven’t
seen much else on them).

2.  Little LEO.  Still a fluid situation, as far as I know it is hard
to see which systems will be built.  Frequently allocation is far from
resolved.

3.  Global broadband (Teledesic and competitors).  Lots of companies
are now proposing GEO systems with inter-satellite links aimed at this
market (according to a recent post by Wales these use spot beams to
re-use frequencies in different places on earth).  For example:
Spaceway, Astrolink, Cyberstar, KaStar.

Projections (4/05/96)") at the OCST web site,

"Secret Satellite" on Discovery Channel

For everybody’s information, the National Reconnaissance Office (NRO) has
issued the following media advisory:

"Secret Satellite" to Air on Discovery Channel

The NRO Public Affairs Staff would like to call your attention to a second
television documentary featuring the CORONA satellite program.  "Secret
Satellite" airs on Sunday, August 25 at 9 p.m. on the Discovery Channel.

The hour-long program details the efforts of CORONA’s space pioneers in
designing, launching, and operating the nation’s first photo
reconnaissance program.  During on-camera interviews, CORONA team members
share their insights into the program design, engineering problems and
solutions, and the personal challenges of developing leading-edge
technology in a covert environment.

The program also addresses the creation and development of the National
Reconnaissance Office from its USAF and CIA roots.  The telecast concludes
with scenes of the NRO Headquarters.

"Secret Satellite" is a follow-on to "Spies Above," which aired March 11,
1996 and focused on the impact of CORONA imagery on national security
during the Cold War.

NASA policy on non-US citizens

Hello out there,

do any of you know what is the outlook for Europeans (or others) to work
at NASA? What about work permits, eligibility, and such? And how does one
know about job openings in the first place? They do not seem to be in any
of the Web search engines.

Thanks for any help,
Max

NASA Spacecraft/Vehicle Level Cost Model

Spacecraft/Vehicle Level Cost Model (8 Mar 96)

http://www.jsc.nasa.gov/bu2/SVLCM.html

The Spacecraft/Vehicle Level Cost Model (SVLCM) is now available on the
World Wide Web.  This is a simple online cost model that provides a useful
method for quick turnaround cost estimates requiring only rough,
order-of-magnitude precision. The model can be used to estimate the
development and production cost for spacecraft, launch vehicle stages,
engines and scientific instruments. The SVLCM is a top-level implementation
of the NASA Cost Model (NASCOM).  This model is written in Netscape’s
JavaScript and requires Netscape Navigator 2.0 or another browser with
JavaScript capability.

How much would Mars Direct cost?

I’ve read some of the web pages about Zubrin’s Mars Direct proposal,
which seems pretty damn cool. But I didn’t see any cost estimates.
Has anybody got a ballpark figure for the first mission, and then
each subsequent mission?

   Thanks Rand.  And let me also add, that Rand is one of the _very_
few people I know who walks the walk, as well as talks the talk, about
new market commercial space ventures.  We have had occasion over the
past years to exchange a lot of views on these markets, and I may not
agree with him on all points — but I respect him and his opinion very
highly.  I always learn something from talking with Rand.

    Yep.  The art, and the science, of business analysis is in dealing
with uncertainties.  No piece of data is ever perfectly exact and
accurate — and the environment and future events and other
intangibles may dramatically affect the shape and outcome of a venture
mid-course.  
    I don’t have good enough data on the new markets for space
transportation to take them to investors for a major (billion dollar
range) new investment, and I’ve spent quite a few years studying them.
Rand also has done the same, and has done some very interesting and
useful work with his own investments — which is part of why I highly
value his perspectives.
    Where we differ in opinion is in "honest man" differences.  That
is, with two honest and rational people looking at the same set of
data — can there be more than one conclusion drawn from the data?  
Yes, in this case because of the high levels of variabilities and from
the level of precision and accuracy of the data — Rand and I can come
to differing opinions, based upon various assumptions.  But I think I
can understand his logical chain of thought, and compare it to mine to
see where the differences are.  And that is *very* useful to both of
us.

>Our biggest point of disagreement, as I’ve pointed out in another

    True.  I’ve been getting a force-fed indoctrination in industrial
and corporate decision making and venture structuring.  That’s more of
an traditionalist view — but is very important in understanding how
large commercial space ventures like satellite telecommunications
ventures and launch vehicles and the like are being done.  And I think
that’s going to be important to put together the deal which makes some
of these type ventures happen.  Rand on the other hand, is steeped in
the entrepreneurial/ small start-up venture culture.  A different way
of doing business — but no less valid as a way of getting into the
market in other circumstances than I am assuming.
    I don’t think we need new markets to make a RLV venture work —
that is, justifying the venture to investors to get the venture up and
running.  But we want to energize the new markets as that is where we
will become "sick rich".  
    On the other hand, I recognize Rand’s point, that breaking the
traditionalist paradigm (as seen in the entrants for the X-33
competition, for example), will also break my assumptions and chain of
logic.  If that happens, then all of my bets are off.  
    We disagree in some of the details of markets, and obviously
disagree on the details of some of the strategies which can be
pursued.  And over a few beers we can argue for hours as to which
strategy might work best against which market.

    Hmmm…  rather than saying the aerospace industry isn’t
entrepreneurial, I’d point out there are multiple methods of
entrepreurialism  (as was hammered into me in my MBA program).  And
different strategies can be used for different circumstances.  
Aerospace investments, at least up into the 1970′s or so, were rather
large bets against a company’s bottom line.  While the percentage bets
against net worth are not any larger than that found in small
electronics firms, for example — the sheer scale and magnitude of the
dollars and risks has forced certain risk-coping mechanisms in place
which are encountered when such ventures are developed, analyzed,
approved, and executed.   Other industries have similar mechanisms,
with variations dependent upon the scale and industry specifics.  

   Part of these mechanisms have to do with the size of the venture
and consequences of failure back upon the stakeholders in the venture.
For a small company (say 50 employees), betting $10 M equity against a
$100 M payoff — that’s a huge $2M/employee payoff, against a $200 K
per employee risk with a pretty short time scale (typically less than
5 years).  Stakeholders, such as VCs and start-up principals accept
that risk and usually have risk coping mechanisms (ie, VCs spread
their investments over many startups, start-up participants share
costs, etc.)  And given an up-front buy-in by the participants —
people will gamble big against that.  
    However for a 100,000 employee company, that same equivalent amount
of reward would have to be around $2e11, or around $200 Billion.  And
there are very few ventures which can generate this level of return in
the same time scale.  And the same equivalent level of risk would be
for $2e10, or $20 B — which would not only be more than most companies
net worth (Boeing for example has a net worth of around $8B, MDC around
$4B), but if that venture failed would probably take downs several
major banks and financial institutions as well as a major Fortune 100
level company.  Moreover, with 100,000 employees, you will get a
smaller percentage willing to risk their incomes for 5 years, and you
also have stockholder and financial backers not willing to gamble large
chunks of their equity on such a risky venture.  
    This, through corporate boards of directors and shareholder
meetings and from major institutional investors starts to limit the
amount of risk a major company can take on.  Yes, companies will still
gamble big time — investments in the Billions of dollars are made
every day — but the pure risky "swing for the fences" ventures are
_very_ hard to justify.  The number of dimensions of risk start to get
limited — and ventures with multi-dimension risks including technology
_and_ market _and_ cost _and_ regulatory risks have a hard time.  
    This starts to shrink the pools of money available for "swing for
the fence" gamblers.  For example, the largest first/second round
venture capital investment last year was a pooled investment in the
$25-30 M dollar range — for a health care startup in managed care
(not with huge amount of market, or technology or cost risks).  As you
increase the dimensions and magnitude of risk from technology, market,
regulatory environment, etc.  the amount of "swing for the fence"
gambling money decreases.  
    At the other extreme, there were hundreds of billions of dollars
available in the industrial capital markets used for such things as
expanding production lines, and financing additional products for
existing markets.  Lots more money available for a venture to tap
into, but you have to show lower risk to attract the funds.

   Scale and nimbleness becomes an issue — and is one which is
wrestled with on every major venture.  It’s not the companies don’t
want to become "sick rich", its rather that they can’t find the funds
to go out and gamble on "swing for the fences" without having huge
consequences from internal and external stakeholders if they fail.  So
they will attempt to risk limit the consequences.
   But if you risk limit too much, you not only never get anything
done, you become very vulnerable to more nimble competitors.  
Therefore you want to gamble more, but you are limited to the scale
you can employ without limiting your nimbleness in the venture.  This
becomes a very interesting and dynamic issue in multi-dimensional
optimization — and one in which there is a lot of art, as well as
science, in structuring the executing the venture.
    I disagree with Rand’s implication that a good investment will be
overlooked — with the caveat, the investment must be structured within
a reasonable risk consequence portfolio.  (As an aside, I know first
hand that several of

Visibility of Progress-M32 & Mir

Last night my SO and I had a go at spotting Mir (this was
about 2100 UTC on the 19th of August). We picked up
Mir fairly easily, but then she spotted a slightly dimmer
object, travelling at the same speed in the same
track as Mir, several (4-5) degrees behind the space station.

How likely is it to have been the Progress M-32 freighter
I’ve read about on the Net? Is it likely to have been
visible?

Artemis Project on TV…

  The Artemis Project will be featured on "Future Fantastic," a documentary
on space and the future.

  "Future Fantastic" is a multi-part documentary hosted by Gillian
Andersan, the actress who plays Agent Scully on the X-Files. It is a
much-publicised, prime-time production being led by the BBC. It is the only
documentary being hosted this season by Gillian Andersan, despite her
bombardment with requests.

  The Artemis Project will be one of the features of the half-hour show on
which it appears, including the results of the lengthy interviews of
Gregory Bennett and Simon Rowland, which took place at Artemis ’96 in
Houston.

  The UK broadcast may have a viewership as high as 10 million. It will be
later shown by an American network, the Learning Channel.

  At Artemis ’95 in Huntsville, there was a camera crew from the local
television news. This time, the conference was unannounced; despite this,
both working conferences had coverage from the local newspaper (last year
the article was syndicated and appeared in hundreds of newspapers across
the US).

  The series is currently airing on BBC-1 in the United Kingdom, and the
program featuring the Artemis Project will air in a few days. For those of
us in North America, The Learning Channel will show the series sometime in
the Autumn.
