As much as I would love to go back to the moon or Mars, my two cents
is the next manned expedition to an extraterrestrial body should be an
asteroid.


Dear Mr. Martin,

The Columbia tragedy snip

All very nobel and an impressive academic gang, but it won't come to
anything. Politicians live by differnt rules.


Yeah, likely so, boy a nice Arizona meteor crater impactor , say in
Kansas, (or just about anywehre) would sure cut through a lot apathy
about asteroid strike threat!

Yes, but I willing to bet you, me and everyone in this newsgroup will
be long dead before it happens.

We might all be dead before this happens!

For something like the Meteor Crater in Arizona that's a safe bet.
Smaller yet dangerous asteroids are more probable.

Are you aware of the Tunguska impact at the beginning of the 20th
century? (Not really an impact since it blew up above the earth, but
still very destructive)

Take a look at :
http://www.gsf.fi/paleo/files/fenno.html

there are two from last 10K years and Kaali is about the same distance
from Helsinki, Riga, Stockholm and Tallinn. It has a ~ 100 meter main
crater.


I don't know what the odds are that we'll see a Tunguska sized impact in
the 21st century.

Quite good I fear.

I'll try to find something else useful to do. Besides, in real life,
unmanned spaceflight isn't HAL. People still run the mission, only by
remote control.

Be kinda hard for a Saturn or Pluto mission with the time dely as some
kind of AI in the robots will be required, and that puts humans out of
the robots decision loop.

That would surprise the hell out of the Pioneer folks, or
the Voyager folks, or the Cassini folks.


Those probes although clever are not as smart as the ones the poster
is proposing.

Don't you belive it, you'll be twanging your harp before something big
gets a bulls-eye on Earth. Jupiter protects us from a lot of such
things.

Cuts both ways, Jupiter provides a route by was of resonances in the
Asteroid Belt and dynamical chaos of delivering asteroids into earth
crossing orbits.
Some times deflects long period comets , sometimes can deflect long
period comets and other comets into orbits we would not like.

Anybody remember the 1969 object that passed over Idaho but didn't
hit? Left a whacking great vapour trail, was estimated at that
time to be of the order of ten metres. It was recorded on video,
or I guess it would have been 8mm film back then. Now that is
as near a miss as you're likely to ever see. Like ten miles or
so. Not big enough for world shattering devastation, but if
it had skidded across Boise it would have attracted a bit of
attention...

(Greg Kuperberg) made the phosphor on
my monitor glow in such a way as to indicate that:

I would have to agree with Kuperberg that manned space flight in its
present form is a lot of P.R. with little real return.
Key words being "in its present form." There's no law of the universe
that requires that it remain in its present form.

Well, yes, and I'm not going to predict anything about the distant future.
But by the same token, there's no law of the universe that requires
manned spaceflight to be worthwhile either. It isn't worthwhile now
and it won't be worthwhile for the forseeable future.

We already know that it's worthwhile, because millions of people would
like to do it.

A computer can't visit space, and provide me with an experience,
better than I can, any more than it can visit Colorado.

If the rationale is that you enjoy watching it, you can wait until it's
sponsored by pay-per-view TV.

I'm a doer. I guess you're a voyeur.

Nit: Millions of people *say* they would like to do it. That may or
may not reflect the number of people who actually show up at the

If only a small fraction if them are telling the truth, the fact
remains that it is worthwhile. It's just not worthwhile to voyeurs
and monomaniacal science types like Greg Kuperberg.
