Technology has always found its greatest consumer in a nation's
war and defense efforts. Since the last attempts at a "Star Wars"
defense system, has technology changed considerably enough to make
the latest Missile Defense initiatives more successful? Can such an
application of science be successful? Is a militarized space
inevitable, necessary or impossible?

I'd written that
" The lasar weapons programs are fatally flawed
because reflective coatings are so effective (and can easily shed
999/1000ths of the energy that hits them http://www.phy.davidson.edu/jimn/Java/Coatings.htm
and gisterme corrected me from text on the link that said
"98% reflectivity may be achievable." However, http://www.phy.davidson.edu/jimn/Java/Coatings.htm
had two interactive displays, as well. I got my number from the
second display.
On the second display, punch "6 layer mirror" and then hit "add
layer pair." - - - 999/1000's is achieved with an 8-layer pair. More
layers would be easily arranged.
Gisterme goes on to make a point that direct
deposition of reflective coatings would be technically difficult or
impossible. I hadn't meant to suggest something that had to be
"built of unobtanium."
I was thinking of reflective decals, and almost (but not quite)
said so in rshowalter
9/29/01 6:44am . Pardon me, gisterme when I wrote
" The reflective coatings are easily enough made
and applied to surfaces. Anybody who has ever used contact paper,
or put a decal on a plastic model, knows how easy. "
I didn't explicitly say reflective decals. Or say that reflective
decals are easy to make. But I believe they are -- at least with
reflectivities well above 95% -- enough to defend well from lasar
weapons, even with the lasar weapons "perfect" in other respects. .
Would 99%+, or even 99.9%+ be feasable? My guess is that, at least
for the 99% level, such decals could be designed, set up, and tooled
for under $20,000. Enough to invalidate lasar weapons as major
"missile defense" devices. . And in a way that is SO obvious, that
it has to be anticipated.

For a sense of why lasar weapons issues matter about missile
defense, and other things, I think this is an interesting article.
The Next Battlefield May Be in Outer Space By JACK HITT http://www.nytimes.com/2001/08/05/magazine/05SPACEWARS.html
By reasonable (economically disinterested) professional
engineering standards, lasars for MD and for offense are ruled out
because it is so easy to defend against them (and for resolution
reasons, as well.)
That does nothing to invalidate the very important reconnaissance
capabilities of space. But it goes a long way to adress concerns
that the Russians REASONABLY have about our missile defense
prospects. Our best defense against rogue state missiles, by miles,
is to ally with Russia, and other countries, outlaw them, and
enforce the prohibition.

In gisterme
11/9/01 4:36am gisterme , referring to a statement that
still seems reasonable to me, says that I "never bothered to even
try to refute the calculations I presented that show that statement
is not true. Remember? From public sources, based on existing
technology?"
Gisterme , I dont know the calculations of yours that
you're referring to. Could you point them out? Thanks.

Showlater: I note the name 'Jack HITT', he's right, and on target
.. an advocate of 'ORDER' rather than the free-for-all militarised
space. It's logic versus greed - as in returns for a certain sector.
On the Afghanistan issue. The guy on TheNewsHour was thinking
that the Arab world should take from the West - only what it needs,
rather than become westernised ... because there's a fear of that.
Thinking this over. All the West has is knowledge and knowledge
of efficient process. So when the Arab world has concerns re the
West, re knowledge ... what's really going on?
Checking out ISLAM one notes that the originator was looking for
incremental improvements to make the lives of individuals better.
The Islamic movement split and splintered. The leaders of these
groups moved to looking inwards to 'self' with 'power' ... greed
steps in at this point.
I've never really met anyone from the Arab world who wants to
step back in time, it's usually .. oh we have to do this, dress this
way ... etc .. expressing the hope that they will have more freedom
and fewer controls a couple of decades hence. The people generally
are forward looking.
The problem with the Arab world therefore has to be that the
LEADERSHIP needs to move into the 'world', be visionary, set goals,
and look towards the real needs of the people - not their own.

Note that the US is in trouble once again re allowing Children to
fly planes. Take those suicidal odd-bod kids off the tarmac!
Intersting that this latest incident - illustrates my point above
re the minds of youth being polarised ... seeing the world from
opposite-end spectrums, rather with a holistic rounded view.
Noted that none of the six heads at the school he attended knew
the 15 year old. Indicative of the fact that promotion-power-rewards
are directly related to 'paper-pushing' .. and have little to do
with community:leadership. So the kid had good test scores - yet no
common sense!

Warlords ... indicates a competitive spirit - abroad. Were this
spirit to be channelled into competitive Nation BUILDING .. rather
than negative killing ... Afghanistan might become a fine place.
Wonder if lateral thinker de Bono has translated his
'thinking hats, shoes', and team-building approaches into the local
lingo?
