Default Earth almost put on impact alert

"Astronomers have revealed how they came within minutes of alerting
the world to a potential asteroid strike last month.

"Some scientists believed on 13 January that a 30m object had a
one-in-four chance of hitting the planet within 36 hours."

http://news.bbc.co.uk/1/hi/sci/tech/3517319.stm

Scary.

Indeed. _Science_ reported "It was all over in 6 hours, but the
commotion triggered last month when a threatening asteroid popped up
still has astronomers buzzing. The incident demonstrated that
researchers have little idea how they should respond to the detection
of an object that may hit Earth within days. 'Nobody was in charge,'
says planetary scientist Clark Chapman of the Southwest Research
Institute in Boulder, Colorado. 'Things worked out right, but it was
more or less good luck.'"

The _Science_ article concluded "Late that night, a Colorado amateur
astronomer averted an embarrassing false alarm by failing to find
2004AS1 on its predicted collision course. A day later, European
professionals relocated it, and MPC put out a formal announcement
confirming it wouldn't be hitting anything. That hasn't resolved
matters of risk perception, but all agree on the need to figure out how
to respond to future alarms."

What gets me is that some astronomer contemplated calling the White House to
inform the President of the United States about an asteroid discovered by
LINEAR, a U.S. Air Force project. Surely in the post-9/11 world, the Air Force
has protocols to keep public officials informed about such things? Right?

The again, the down side is Earth suffers an impact, with no warning given,
because they could'nt make the analysis in time to say
"We are 100% certain of impact" I wonder were the % line of public
notification is?

To be honest does it matter? At such short notice it is unlikely that any
real effective evacuation could be done and you could argue that causing a
panic could simply make things worse.

Yes that is true, but I would like the people with fingers on 'the' button to
know before it happens.

The problem is that if the object is not guaranteed to hit us, but someone
(quite who would decide, the UN?) who decides to try and blow up something
coming in, or even nudge it away , could end up turning it into several
large lumps one or more of which may then definitely hit us.

We've argued this issue before on this group and I don't think we've ever
had any agreement. So god knows what chance there would be for the UN. In
the movies Deep Impact & Armageddon there was never any reference to the
United Nations. The USA appeared to act on it's own on behalf of the World.
I somehow doubt if that would be accepted in real life.

Does it matter? Hell yes it matters.
Even though I may not have time to escape, I'd like at least to know what /
where impact is so I can spend my last moments of life with my family
viewing the most spectacular astronomical event in our lifetime!

I sure you know best for your own situation.



But for me - I wonder if I might not want to be away from my family since I
am probably going to be seeing them very shortly for eternity. I'm thinking
of going ice skating or something I've never done in L.A. Maybe go into a
Pottery Barn - never been there. I also would like to really floor my car
over the Tehachapi pass. Really really floor it. But I am afraid that there
might be an exodus of people trying to somehow survive in the wild lands of
Central California and the Great basin areas.

Also, what if there were some kind of "sweet spot" where the forces exactly
canceled out like in a acoustically dead spot in a theater? Maybe even
though the titanic shock waves and land waves and disruptions in the
atmosphere bringing perhaps, it great rips, spacelike conditions to the
earth... maybe there is a spot where everything cancels out and you would be
ok?

That could just as easily be in a Pottery Barn as anywhere else. You might
be standing there looking at the four foot high Aztec vase for the front
entry and not notice anything, decide there was a reason you never went to a
Pottery Barn, vow not to come back, open the store door and there is the
darkness of oblivion maybe with a few mountain ranges floating far away over
the void and the edge of space rushing toward you as the micro atmosphere
surrounding the store floats away.

Jump in the vase and seal yourself up with handfuls of linen products and
you'd be ok. It is hard to be truly brutal but if you had your family they'd
all want in and there wouldn't be room.

Heavy Sigh. Yes, I miss Douglas Adams too.
