Send In the Asteroids

Earth-crossing asteroids - objects with highly elliptical orbits that cross the plane of Earth’s more circular solar orbit - are whizzing by us in the dark reaches of space. According to a recent post in Salon.com, "At least three hundred of these potential killers are known, and in the next few decades some of them will pass uncomfortably close."

"A recent survey of how people are most likely to die rated asteroid impacts pretty low - something like 1 in 100,000 . . . . about the same probability as death by lightning or a tsunami . . . . Chances are excellent that you don’t have to worry, nor most likely will any of the next hundred generations. But we can be absolutely sure that another big impact of the dinosaur-killing variety is coming someday, somewhere. In the next fifty million years, Earth will suffer at least one big hit, maybe more. It’s all a matter of time and probability."

Cold comfort, says Miguel. You don't have to tell me twice. Probabilities be damned, if something bad is going to happen you can bet that someone will be around to worry me about it beforehand, over the 50 million years or so before it hits. This is something even the Transportation Safety Authority can't protect us against.


"Get your hands off my cupcakes!"


As the Final Day approaches, perhaps as early as 2029 when a 900-foot diameter rock is predicted to cross Earth's path well inside the Moon’s orbit, what remains of American capitalism will market asteroid survival in climate controlled asteroid shelters, home-brewers' survival kits, post-crash courses, late-night cable reality programs ("Asteroid Wars"), seminars and workshops, two-year associate degrees, certification classes and pre-loaded assault rifles at End Time prices. 

American Protestantism will feature endless Youtube clips of Pat Robertson explaining how this all comes of our forebears' pact with the Devil sometime before the American Revolution; boxed CD sets of Joel Osteen sermons ("This Wasn't Supposed to Happen to Us, Lord," "Why Is This Happening to Me, Lord?", "Leveraging the Asteroid to Realize Your God-given Prosperity Potential," "Thank You for New Marketing Opportunities, Lord"). Not to mention a spate of Final Days bumper stickers.

Astronomy Sucks!

Asteroidal impacts may not occur often, but when they do they take out really big things - every last dinosaur, entire NFL football seasons, white ethnic majorities, Republican prayer breakfasts, African countries and Chinese dams. On the other hand, there's no denying they have their upside: no more marriage equality initiatives to vote down, no more worries about the Violence Against Women Act (since, in the aftermath, violence will be pretty much equal opportunity), no more Equal Opportunity/Affirmative Action initiatives, no more EPA. Hell, no more E, come to think of it.

Admittedly there are "asteroid skeptics" among us, and they do raise some pretty tough questions for asteroid alarmists like Miguel - most notably, this humdinger: if, instead of God, it really was an asteroid that destroyed all the dinosaurs, then how did all the other "passengers" on the ark - mammals, white people, unicorns - manage to survive? A stumper, I'd be the first to admit.


 "Head for the big wooden thingy!"

But seriously, what can we expect should the planet suffer asteroidal impact? "If a ten-mile object hits the oceans—a 70 percent chance, given the distribution of land and sea—then all but Earth’s highest mountain peaks will be swept clean by immense globe-destroying waves. Nothing will survive up to a few thousand feet above sea level. Every coastal city will utterly disappear." For all of that, every other city will probably disappear as well - maybe Lhasa will be unscathed but who wants to live there? 


"I thought I just saw Fukushima go by."

Let's face it, if an asteroid does hit Earth there won't be much anyone can do to stop it. "When one of these projectiles is finally observed, it will likely be much too close for us to do much about it. If we’re the bull’s-eye, we may only have a few days’ warning to settle our affairs."

So let's say I have three days warning - probably a realistic estimate - what would I do? Well, for starters I'd probably get myself to Portland's 10th annual "Filmed by Bike," where I could get several items ticked off my bucket list all at once. First, I'd get to visit Portland, a city already renowned for a sort of precious idiocy, just before it's washed off the face of the earth; second, I'd finally get to attend a film festival featuring movies filmed entirely by people riding bicycles; third, I'd get to ride my bike - a ride to the opening night street party no less, led by cycling celebrity Gary Fisher; and finally, dream of dreams, I'd get to meet someone named Ayleen Crotty. After that you can send in the asteroids.

Down Around Our Heads (update)

I was driving through the post-Rapture landscape of western Kansas yesterday along a two-lane blacktop, scarcely another truck passing me for mile upon mile beneath an unblemished sky, lost in the comforting miasma of my own profound thoughts, when off in the blue middle distance beyond my bug-soiled windscreen something brilliant incandesced into the far horizon like a P-51 into a grandstand, trailing an instantaneous silver wake. It flashed and was gone in an instant - an enormous meteor, the Second Coming, a manifestation of the Evil One - I had no clue what I'd just seen. I'd never heard of a meteor sighted in broad daylight but I couldn't think what else it could plausibly be. I like to think I might have been the only person in the world to have seen it. It was brilliant, hot and instantaneous.

No, not like that.

In fact, meteors in broad daylight are occasionally reported, although as this site chronicles daytime sightings in Texas and Kentucky, I would normally be inclined to remain skeptical since the cognoscenti all insist the Rapture will come to Texas first. Then Kentucky, probably.

Jesus: The Tortilla ("Jesus, the tortilla!")

But I saw something on the Kansas horizon yesterday and it seems that the only plausible explanation could be a meteorite. Well, it seemed yesterday the only plausible explanation - until I spotted this headline in the New York Times (my daily paper, as you may have surmised): "Falling Satellite Could Land in U.S."

Even Miguel can put dos y dos together.  Apparently, even after NASA lost most of its funding there are still six tons of malfunctioning NASA hardware loose inside the earth's orbit and on their way down - "Falling Satellite Could End Where It Began, NASA Says," reads the sub-head inside the Times site, proffering a textbook example of retributive justice if ever there were a fair exchange of eyeballs. "Where it began" would be presumably somewhere in Florida. I could probably live with the horrible consequences of that. NASA officials expect "re-entry" late today or early tomorrow. "Re-entry" is another way of saying that "At least 26 pieces, the largest 330 pounds, are expected to survive the plunge and land along a path 500 miles long."

Let's be honest - none of us has a clue as to what the hell is going on in outer space. We have no idea how many people are floating around up there "manning" some contraption or other.

(Has digital images of you in Under Armour.)

We have no idea how many Chinese or American or Pakistani or Iranian space launches have sailed off over our unsuspecting heads, manufactured to less than exacting standards by impoverished workers unprotected by OSHA labor standards under conditions the EPA could never sanction, a payload waiting only to plummet into your basement and destroy your crop of hydroponic medical marijuana ("No! - it's organic arugula.")

 Iranian space probe

Not to mention private companies sending their own junk into space. The Times report concludes that "About one satellite five metric tons or larger re-enters the atmosphere every year. For example, on a test flight of its Falcon 9 rocket (see photo) in June 2010, the Space Exploration Technologies Corporation placed the second stage and a prototype capsule into orbit. That object . . . came crashing back to Earth two and a half weeks later without causing a media ripple." 

Corporate returns

Public indifference to a rain of potentially lethal metal on our heads is disturbing. But what other response makes sense under the circumstances? The prospect invites the same sort of fatalism one might expect on learning that the stock exchange has just eaten your retirement fund or the FBI has been intercepting your cell phone calls or you got a computer virus from downloading porn or the Koch Brothers will be mining coal in your back yard. What can you do but shrug, turn up your collar, and mutter self-referentially, "Poor bastard." Not a long term solution, to be sure.


For my own part, I couldn't care less. I've been too busy watching the Republican candidates in foro, debating the finer policy points of the End Time. Some days, the Rapture just can't come soon enough. The Long Term Solution, I like to call it.

"Back from Outer Space"

Update 10/22/2011:  from The Daily Beast 

German Telescope Will Fall to Earth

Didn't we just do this? A two-ton German space telescope will crash back to earth today or tomorrow, but scientists can't determine where it will land. The satellite, launched in 1990, will likely break up into 30 or so pieces as it goes through the atmosphere. The largest single piece, the telescope's mirror, is heat resistant and weighs about 1.7 tons. It comes just weeks after NASA's six-ton UARS satellite crashed back to Earth, landing in the Pacific Ocean. NASA was unable to predict where UARS would land, but the odds of it hitting a populated area were infinitesimal.
