It's in hibernation after its second comet encounter, and will probably
not be revived again -- it's too low on fuel to do much more, and its
next Earth gravity-assist opportunity isn't until the end of the decade.
Thanks. Launch/encounter dates, anyone?

Well, the Pioneer Venus orbiter should have rated mention unless the FAQ
was updated very recently, since it only just died.
It's in the FAQ, I deleted it from the list since it's dead.
Pioneer 6 is still alive, and I think one or two of its later siblings
are too, in near-Earth heliocentric orbits.
6, 7, and 8, according to the FAQ. I missed them.
Thanks for your other tips.

That is the case. I should have cooled of before writing the

You need to read this newsgroup more often. The news broke after the

First of all, the name is P/Swift-Tuttle. Second, both dates are wrong;
the year of the next perihelion passage in 2126. Third, the recovery was
not by Steel himself, but rather by a Japanese amateur astronomer by the
name of Kiuchi. Fourth, didn't your site receive the earlier postings
that would have clarified all of this? Check out IAU Circular 5636 for
details. This one was posted, though I don't encourage this practice.

The comet that you are referring to is Periodic Comet Swift-Tuttle,
which is responsible for the Perseid meteor shower each year. It was
recently recovered by a Japanese comet hunter. When experts started
analyzing its position, they discovered that its perihelion had been
delayed several days as the result of nongravitational forces---jets
of gas coming off the comet had essentially acted like braking rockets.
IF this continues at the same rate (and that's a mighty big if), the
next time the comet returns in 135 years it COULD hit us. But the
uncertainties at this point are very large. Astronomers are obviously
watching it very closely to try to refine the orbit and their
predictions.

There is a greater change of dying from a train wreck or a car accident than
getting plowed by the comet.
Another thing to consider: How big is this comet? It doesn't have to hit
us to do some major damage. YOOGE tidal waves, earthquakes, knocking
the earth out of it's orbit, etc. Y'know...minor worldwide disaters.

The person in question, an Hispanic woman who said the government ought not
to spend money on space because it only helps white people, already believes
that people should be taxed. She just thinks this money shouldn't be spent
on something she considers frivolous. My numbers were meant to help her see

I'm just trying to show people how to see the big picture. Also, I'm
assuming that spending on science increases the productivity of individuals
over time. Maybe you would dispute that assumption.

It won't be ten years since Clinton will be a one term president. At the
end of which (if we are successful lobbying Congress) we will have an

I'm a software designer, dammit, not an engineer :-) so I don't have
an answer on how much force would be required to deflect or destroy an
incoming comet. The force required would obviously depend on the objects
mass and velocity.
David Langford's WAR IN 2080 (an interesting speculation on the shape
of war in the future) deals with the use of asteroids (and other hunks
of rock floating around in space) as weopons. At high enough velocities
, an asteroid of sufficient size would be almost impossible to stop
without some form of mind boggling technology (such as a device that
soaks up inertia). Even if you blew the incoming object apart, many of
the remaining chunks would probably still hit the Earth.
The nastiest variant on this idea that he describes is the 'Relativistic
Missile'. This is an object (not necessarily of all that great mass)
which has been accelerated to near relativistic speeds (something on the
order of .7c) and aimed at whichever planet you don't like. Given the
enormous velocity of the object it would be hard to detect and difficult
to track, making it almost impossible to stop. When it hit the planet
the energy released would be enormous.

Newsgroups: sci.space,sci.bio
To sci.bio readers: this is from a discussion going on in sci.space,
about the current Search for Extraterrestrial Intelligence
(SETI) projects. A big question in that field is the
probability of (some form of) life evolving in conditions
similar to those on primordial earth (it's generally believed
that such conditions are reasonably common and that the
evolution of intelligence is reasonably likely given life).
I'd appreciate any comments from molecular biologists.

Well, I disagree, I'd put it at 0.1-1.0 (formally I'd actually
put it at 0.5 if really pressed) but then we have very poor
sampling on that.
Why so high? Can you get a molecular biologist to agree with you? The
old `amino-acid soup' theory has been largely discounted (on the
grounds of extreme improbability, funnily enough) and replaced by new
theories involving such things as self-reproducing systems based on
clay minerals. My claim is that this sort of system is still very
unlikely. The anthropic principle (in any form) says that our sample
(of one) tells us nothing without further analysis.
Maybe further discussion on that line should move out of sci.space
Agreed, hence the cross-post.

First of all, the comet's name is P/Swift-Tuttle, and it's the parent comet
of the Perseid meteor shower, recently recovered heading in toward its late
1992 perihelion passage, the first since the discovery apparition in 1862
(though the comet has now been linked with the comet observed by Kegler in
1737).
Second, replace the "will strike" by "might strike". Just like any Perseid
meteor, the parent comet also has the potential for running into the Earth.
The uncertainty in the time of perihelion passage at its next perihelion
passage in 2126 includes the date of the Perseids, namely August 14, so it
could theoretically hit the Earth, though the probability is something like
less than 1 in 10,000. Actually, considering the 10-year error in the
current perihelion passage, one could have claimed in 1862 that the comet
might hit the Earth in 1992, but it isn't going to happen this time around.
Then again, once the identification with Kegler's comet was made, that 10
year uncertainty shrank substantially, and August 14 was no longer within
the uncertainty.
Continued observation of the comet as it rounds perihelion and heads back
out should allow a better determination of its orbit and nongravitational
parameters, permitting a more definitive calculation of it 2126 perihelion
date. In the meantime, don't get too excited about "The Mother of all
Perseids".
