Science
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?

Questions raised over missile shield effectiveness
PM - Thursday, 27 February , 2003 00:00:00
MARK COLVIN: From a United States point of view, Australia
makes a prime partner in the so-called “Son of Star Wars”
program, not least because of our geographical position in the
southern hemisphere.
But there are big scientific question marks over whether
the system will ever repay the billions it's going to cost,
let alone provide a fail-safe defence against incoming
warheads.
Scientists compare it with the idea of trying to stop a
bullet with another bullet, and given the American test
results so far, it's hardly surprising that American
scientists are calling for a rethink.
Alison Caldwell reports.
ALISON CALDWELL: To the Bush Administration, it's the
solution to one of its greatest long term security problems; a
massive protective missile defence shield, stretching out
across the region. This is how it would work:
The enemy launches a nuclear attack on Washington, sending
an intercontinental ballistic missile into space. Within half
an hour it will have re-entered the atmosphere, and wiped out
the National Capital.
But instead, an early warning radar would locate the
missile and track it. A military base on a tiny pacific atoll
would be notified, and within minutes America would be sending
its own missile back up into space to destroy the incoming
enemy missile.
President Bush wants the defence shield to be operational
by 2004. A conservative estimate of the likely cost of a
layered missile defence system is just over 1 trillion
dollars. Demonstration test are underway, with less than
positive results. Many are asking, why bother?
TED POSTOL: There's no science here at all. This is just
made up by people in political positions.
ALISON CALDWELL: Professor of Science, Technology and
National Security Policy at MIT, Ted Postol is an ardent
critic of the proposed National Missile Defence System. He
says the idea is fundamentally flawed.
TED POSTOL: The United States has been unable to
demonstrate that it can tell even the simplest of decoys from
warheads. The testing has pretty much verified that they can't
tell the difference, which basically means that the missile
defence system that the United States is currently deploying
has no chance of working against any real adversary.
ALISON CALDWELL: When they say to us technologies are
developing at such a rate in the United States that this will
be a legitimate form of potential defence against any threat,
is that overoptimistic?
TED POSTOL: Well, I would say it's a scientifically
uninformed claim. What the missile defence system that the
United States is currently deploying tries to do is tell
decoys from warheads by basically looking at them through an
infrared telescope that is part of the kill vehicle that
actually tries to make an intercept.
So this is the equivalent of... since you're looking at it
through, essentially what one would call optics, even if it's
infrared optics, you're basically trying to see with eyes
what's inside a bunch of objects in front of you.
So this is the equivalent of looking at suitcases in an
airport, and based on your visual inspection alone,
determining whether or not there's a bomb inside the suitcase.
The shape of the suitcase and its colour and the material on
the surface have nothing to do whether or not there's a bomb
in the suitcase, so there's no hope of visually inspecting the
suitcase and learning about what's inside it.
Now, if you have better instruments, let's say you have
binoculars or telescopes or microscopes or blue-coloured
glasses or red-coloured glasses, I still have the same
fundamental limitation. I'm seeing the surface of the object,
and what I see has nothing to do with what's inside of it.
ALISON CALDWELL: So what were the reports, what were the
results, say, of the last test series that

DOH! | Murdoch's Fox News channel threatened to sue the
makers of The Simpsons because of program parodied the
channel's right-wing political stance.
.... The Murdoch group took particular offence to those
which lampooned the channel's anti-Democrat stance, with
headlines like "Do Democrats Cause Cancer?"
MARK GROENING: Fox fought against it and said that they
would sue. (laughs) They would sue the show and we just, we
called their bluff because we didn't think Rupert Murdoch
would pay for Fox to sue itself.
