Asteroid 2004 MN4 May Hit Earth After All 857

ControlFreal writes "Asteroid 2004 MN4 was introduced earlier on Slashdot, and although scientists are now fairly certain that is will miss earth on April 13th, 2029, the modification to its orbit caused by Earth's gravity may still cause an impact one or a couple of orbits further down the road, the Times reports; the impact probabilities in 2035, 2036 of 2037 will not be known until the exact modification to its orbit is known; in 2029, that is. By then it may be too late for effective counter-measures. An impact would cause an energy release equivalent to about 1 Gigaton of TNT (~4e+18 Joule), and while that won't cause a massive extinction event, it causes widespread devastation. More info on 2004 MN4 can be found here and here."

        There will be no eulogy. Humanity will die quickly.

        Denial will reign, as no preparations are done to evacuate the planet. Some will say there is no way to evacuate everyone. Others will say there's nowhere else to go. The real thinkers will know, if we had started years ago, we would have had a chance.

        Most will die from the intial impact.

        The impact will crack the planet's crust, resulting in volcanos, earthquakes, and tsunamis, which continue for years.

        Many will die due to the dependance on transportation systems, or more specifically the failure of them.

        A very few will survive in the cold dust and ash filled atmosphere, through the shaking ground, and giant destroying the costal areas. They will survive for many months on their preserved food reserves, and filtered air. Alone, they will consider themselves the lucky ones.

        In the end, none will survive.

        Many millennia later, other civilizations will have grown in far outlying areas of the universe. They will look at the dry and barren planet, covered by rocks and dirt, and say "nothing could have ever lived here. It's always been a dead planet"

        Eventually, despite taunts, archeologists will find disputed traces of life on the planet. Some artifacts will be found. They will be found frozen in the ice of the polar ice caps, or burried in the sands of the vast deserts. Still others will be below hundreds of feet of dirt, on the iced tops of frozen oceans.

        The artifacts will be carefully examined for many years. There will be many theories to what they are, and what the markings may mean. Could there have been life on this far distant planet? Could a civilization have thrived in this desolate place? Maybe these creatures could be a clue to our ancestory?

        In the end, their markings will be considered random discolorations. The artifacts will be labeled as "common rocks", and thoughtfully put into storage well away from public sight.

        No, as egotistical as we are, there will ne eulogy. There will be no memory of anything we've accomplished. We will be part of the dust on a barren planet, spinning slowly around a dying star.

      If the sole reason you want a space program is paranoid fear that we might be hit by a rock, that's a pretty sad reason.

      I'd like to visit the moons of Jupiter and Saturn. I'd like to see other star systems. I'd like to advance our knowledge of the galaxy and universe and try to find other life forms.

      I mean, if people were dying left and right by micrometeorites hitting the earth and blowing out people's skulls but no one in power cared, I'd be concerned. That's not the case here.

      Let's keep the fearmongering to a dull roar here. How sick does our society have to be when someone start's talking like a bad sci-fi thriller about the end of the world?

      The sole purpose of any space program should be like any other science program, to make the unknown known and to expand the horizons of human understanding.

      Frankly, if the meteor is coming in 2035, my opinion is that it's pretty much too late now. Get out your sandbags and automatic rifles and prepare for the armageddon (not the movie!).

      "I hope this rock hits our planet [since it] may be the spur humanity needs to get us up off our collective keisters and establish a viable off-planet colony before it's too late."

      I strongly doubt that. Such a catastrophe will push many governments and citizen groups over the edge of accepting Fascism as a survival tactic. Within such regimes, the ability to look outward to the liberties of space is very repressed. In effect, there will always be a constant reward for killing people and taking their stuff ... and that environment isn't conducive to all the social prosperities and stabilities that we relied upon to even have a space program in the first place.

    in 2029, that is. By then it may be too late for effective counter-measures.

    Bull. 2029 to 2035 gives us ~6 years to prepare. If the asteroid actually posed clear and present danger, then a crash program to build an interceptor could be accomplished. With apologies to Pournelle and Niven [] (warning, associates link), the catch-22 is that we would have to give up our fear of the Orion []. Using standard building practices + what we know of advanced hydrogen bomb design, we could potentially launch an Orion within three years. The options would be to either send it on an unmanned kinetic-impact course with the asteroid, or to send a team ala "Armageddon" (or some other lame stop-the-asteroid movie) to manually plant and detonate the charges.

    If I'm reading the info correctly, the asteroid is a mere 46 gigatonnes. So as long as we get to it fast enough, there shouldn't be any difficulty in nudging it into a higher orbit. Of course, we may only be able to buy some time in the short term. Orbital mechanics is tricky, and not as simple as just "pushing" the asteroid out of the way. We may actually have to push it toward earth to slingshot it into a more acceptable trajectory.

    One way or another, we have the tech. It's just scary as all hell to behold, and in a crash program would almost certainly add a small amount to the nuclear pollution that already exists on our planet. But if it's a choice between three random deaths from cancer or millions dead from a massive impact, I think the choice is fairly clear. Especially when the former is theoretical and the later is firm.

      Well, it's only going to intersect the proper altitude at two points, right? Remember that geosynchronous satellites occupy a very narrow band over the equator. The asteroid may not intersect that plane at all. Even if it did, it'd be unlikely to hit anything.

      I'm not sure what standard spacing is out there, but I'm sure it's at least a few hundred km. The chance of a 1 km object hitting one of these widely spaced, small objects is not great.

      As for perturbation, I'm sure it's negligible. Even if it wasn't, the satellites should have sufficient station keeping ability to stay put.

      That's a lot of space. Geosynch orbit is 22,000 miles. Tack on 4,000 miles for the earth's radius, and it's a shell of space with a surface area of 8.5 billion square miles. Let's pretend we've got 50,000 satellites in that area by 2030. That means 1 sallite per 170,000 square miles. That suggests one satellite occupying a square of space 500 miles x 500 miles, and this thing is under a half mile across, probably less than a quarter-mile. The chances of it impacting anything in that orbit is incredibly tiny.

      Caveat: my math may be off, but the point stands. This object occupies a TINY region of space, and satellits occupy an even TINIER region of space. There's no cloud of buzzing satellites around the planet, they're sparsely populating a huge shell around the planet.

      Check out the timeline for the us space program, and you plot the trend.

      5 may, 1961 - Freedom 7, first manned sub-orbital flight
      20 feb, 1962 - Friendship 7, first manned orbital flight
      21 Dec, 1968 - launch Apollo 8, first manned lunar orbit
      21 July, 1969 - First manned lunar landing
      12 April, 1981 - First launch of space shuttle
      1 feb, 2003 - shuttle fleet grounded

      There isn't much advancement in this curve, and there is a whole lot of retreat. A once proud program, that had the capability to put a man on the moon, just last week, outsourced to get one of thier folks into low orbit. That is a rather telling 'detail' as to just how much advancement is really happening.

      Technology may be advancing, but I wouldn't be counting on anything the usa is developing to be useful in dealing with an asteroid collision scenario. The current administration has priorities higher than space travel, and, the debts they are running up to achieve those goals, will prevent future generations from persueing any meaningful space program during the timeframe in question.

    So this asteroid may not hit the Earth but one will probably slam into us eventually. So why not use this one as a practice run?

    From TFA:

    "This is most likely not the object with our number on it, but one day we will have to address this question and we'll need the technology."

    So let's develop the technology now, when a screw up won't mean utter devastation of part of the planet.

    Lets have Microsoft patent asteriod collisons and then we'll send all the lawyers after the asteriod to deliver a cease and desist order. Worst case scenario is that we're out a few lawyers.

    The exact effects of any impact would have varied based on the asteroid's composition, and the location and angle of impact. Any impact would have been extremely detrimental to an area of thousands of square kilometers, but would have been unlikely to have long-lasting global effects, such as the precipitation of an impact winter.

    I wonder if people will build more bunkers. I know a person who owns a house, and there is a bunker in the back yard, from the days of a USSR nuclear strike threat (Back in the 70's and early 80's the drill for a nuclear strike was to climb under the desk in the school). It looks kinda flimsy to me, I am guessing the salesperson was real good. It looks more like a shed that is half way in the ground.

    But, if someone wanted to make a good bunker, not just to ease the mind, but something to survive in, how deep would it need to be? I live on flat land, so I can not tunnle into a mountain, which I would assume to be the best choice. What is needed for a good oxygen supply, can you generate your own, or do you need an exhaust? How long would you need to stay underground, and where would you store the water and food? And would you have more than one exit out of the bunker, in case one side suffers damage and is burried under?

    I think it would be cool to have a series of bunkers, with some pre-picked neighbors, people you trust. Have 7 or 8 bunkers, maybe a mile apart, each one acting as a node. The chances for survival would increase, and the time would pass quicker.

      This reminds me of that episode of the Twilight Zone, where this block is having a block party, and then they believe the world is going to end with an attack from Russia. The entire episode revolves around the fact that one family has a bunker, and the other neighbors on the block start fighting to get in. Eventually comparing how they should survive over anyone else. The key to having a bunker is to not tell a soul, keep it from the family too if it's at all possible, so no risk of your kids blabbing it.

      I personally love the idea of building a sock-rolid bunker that is so perfect that I am 100% certain to survive the impact.

      Then, when all my friends and relatives in my section of the hemisphere are dead, I'll enjoy struggling for my own survival without clean, readily available running water and food. And then when I get sick after running low on my own hefty (let's be generous and say it's a 12 week supply) of water, I'll be proud of how I struggle to survive with complications from even the most minor of ailments after my modern drug supply is exhausted or proves ineffective.

      When I use my most awsome shortwave radio, I'll be pleased to see how my important politicains (those who lived, that is) are the ones who are rescued first, and will shrug my shoulders as I look at the wreckage of my antennea array from the blast, hoping my small antennea doesnt eat up my power supply before someone can here me.

      I'll be happy to have fully productive days, too, fending off what might be left of others who managed to survive but were less planful as I, as I count my ammunation running lower every day. I'll be thankful my hungry neighbor (the one living in a bunker right next to me) doesn't have a bigger gun than me, either.

      I for one agree that life after a massive asteroid blast would be well on the high odds of survival and most likely fully worth living. After all: With God, all things are possible 8-D.

    They know it will be close in the other years, so why not start planning NOW so that if we know it by 2029 for sure we can either use whatever we worked out or use it for something else.

    The reason it will not happen is because it will still not be eminent and it will be something only those earth saving tree huggers could work with.

    Others have more importand things to do, like making money and the plan of the company only looks ahead 5 years, not 50.

    Well, it was nice knowing y'all.

    I just went through paperwork HELL getting the "Asteroids, Meteorites, and Other Heaven-to-Earth Bodies" coverage removed from my AllState homeowners insurance. This after I put it on there when you FIRST told us it was going to hit us!

    Then I had to call Jean, my agent, and f*cking tell her to shred that whole contract and contact my mortage lender when you f*cking scientists said, "Whoa -- wait -- it might NOT hit after all. Our bad." But, of course, the fax machine at my office was on the fritz that week (screw all-in-one concepts, HP!), so I had to take a 2 hour ride through traffic BACK to my house to get the paperwork and OVER TO Jean's office.

    Now, after FINALLY getting the signature pages right, 'cause Jean's assistant can't friggin' spell "interplanetary" for sh*t, I gotta do the whole g'damn thing again.

    Christ -- I'm going to just leave it on there this time and pay the extra 20% on my homeowners insurance premiums this year. It's not friggin' worth going through all that hassle, having to take time off, explaining to my boss what why I'm having to factor "global extinction" into my homeowner savings plan, etc. Dammit.

    I guess, now, that those f*ckers from Homeland Security are going to change the f*cking color of the alert this week too. Then I'll have to go back and talk with Jean about that "Dirty Bombs, Biological/Chemical Agents, and Other WMDs" clause. Dammit.

    I look at this and know that, like many people, this is a cash vehicle and a licence for the US government to do what always wanted to do. With a big scare like this, the US government can get all the funding it wants to put a nuclear spacecraft into orbit. This will allow them to pour trillions of dollars into the "greater good". While they are at it, they will have a nuclear missile platform in space to control any government it so chooses.... with the "permission" of any partnered countries! "Either you with us, or your terrorists".

    Now NASA gets a blank check to research and develop anything it wants. .. It will be convenient for the US government to use this new "planet saver" platform for other "very important" military moves against "terrorist" organizations.

    Kinda like someone fending off "killer minnows" in a bucket of water using a shotgun and a paint mixer.

    I bet a case of Beer that the US government will make an announcement to develop a space vehicle that has the ability to blast something. Not really thinking that all you need to do is give the big rock a shove, so that it never comes near the earth.

    Earth's geologic history is pretty clear: It says, quite frankly, that single-planet species don't last. Right now we're a single-planet species. We need to fix that.

    Okay, the Extinction Level Event may never happen in our lifetimes (except on the silver screen)... but why don't we just prepare as if an asteroid was to hit us in the near future anyway? History has shown how the innovation spurred by space programs pays off in unexpected ways over decades (the U.S. kept its technological edge for the rest of the century), and this time, ironically, this might even encourage improvements in the more controversial (e.g. nuclear and defense) technologies with a focus strongly on "saving the planet". The investment it triggers should also help economies around the globe - threshold countries want to go to space for a reason even today, as they have realised the beneficial side effects of such programs. Even if all we ever get out of it is only the "usual, boring stuff" like affordable spaceflight, a boost to astronomy and advances in all fields of technology, clean power on earth and a holiday resort on the moon etc., in preparing for an impactor that never comes... it still sounds like "A Good Thing (TM)".

    I can already see cold war style nucular* shelter companies going around and installing shelters underneath folks' houses.

    But what the U.S. government is already doing may be the very same safety measure that is needed: The renewed interest in a moon base, missions to Mars, etc. This exact same space program, I believe, is being put into effect to install a gigantic weapons system in orbit, very similar to the Death Star in Star Wars. This type of weapons system will be sufficient to blow up this silly little asteroid.

    There are about twenty years left to prepare. NASA, you can rest assured, will come up with all kinds of devices to blow this thing out of the sky. And I'd bet you that the government, with all its supercomputers and whatnot, knows exactly when and where this thing is going to strike, and they're not just sitting around waiting for it to happen.

    In the meantime, I know I'll be stocking up on canned foods and bottled water, and I need to buy more ammo for my handguns. If this thing starts coming down in my back yard, I'll shoot at it myself. Or I'll shoot at any looters that come around looking for trouble.

    * I spelled "nucular" correctly. It's spelled according to the pronunciation of the guy I elected.

    There is plenty of time now. NASA has all the time in the world now to develop a new super secret shuttle, and train a small flight crew. Then they will have plenty of time to hire a rag tag bunch of wise cracking oil drillers to send on said super secret shuttle, while first stopping off on Mir to visit with a crazy cosmonaut and refuel. Once they approach the asteroid, despite all their natural personality classes, they will come together and drill the required distance to the center of the asteroid, deposit a nuke or two, detonate said nukes, thus splitting the asteroid in half and getting each half to go its own seperate ways... and then Morgan Freeman will make a public speech glorifying the heroics of this intrepid band, and we will get to see hollywood make movies about their journy and adventure... oh wait... that already happened. Damn... guess we are fucked then.

    For a frame of reference, I Gigaton of TNT explosive yield is about the size of 20 Tsar Bomba class nuclear explosions []. If the asteroid was kind enough to hit us somewhere on land and thinly populated, such as the Sahara Desert or Siberia, the main effect would be a volcanic winter, such as what happened after the explosion of Santorini, in about 1650 BC [] or Mount Tambora in 1815 []. Not a lot of fun, but civilization would probably go on as usual for most places.

    If it hit in the middle of the ocean, a Tsunami could conceivably wipe out many of the major cities on the Pacific Rim or Atlantic and European seacoasts. Tens of millions could die, and many of the developed world's major cities would be laid waste. Whole countries would be crippled, and the ensuing chaos would disrupt world trade, and potentially destabilize entire regions.

    A direct hit on a major population center, such as Southern California, the area around Bejing, China, or Bombay, India would cause millions of casualties and huge suffering, but the effects would be local enough that the rest of civilization would find a way to get by, even if important industries were wiped out. Such a hit would be a relative longshot, but could happen.
