A Hyper-Velocity Impact In the Asteroid Belt?

astroengine writes "Astronomers have spotted something rather odd in the asteroid belt. It looks like a comet, but it's got a circular orbit, similar to an asteroid. Whether it's an asteroid or a comet, it has a long, comet-like tail, suggesting something is being vented into space. Some experts think it could be a very rare comet/asteroid hybrid being heated by the sun, but there's an even more exciting possibility: It could be the first ever observation of two asteroids colliding in the asteroid belt."

Vulcans just can't get enough of that Terran delicacy, smothered in Thousand Island dressing and a thick crust of black pepper.

      An outraged Bones approached Spock at his table and said "Are you out of your Vulcan mind, you green blooded bastard? Do you have any idea of the discomfort you are putting your fellow crewmembers on the bridge in?" Spock slowly turned and replied "It is my understanding, Doctor, that the Enterprise's ventilation system is quite adequate at handling any situation that may arise from my culinary preferences".
      "Well at least take these chewable tablets, then". "I will do no such thing, Doctor. It is not the Vulcan way".

      Kirk was amused no end, silently pondering his secret enjoyment of Spock's emissions while scanning for the outraged faces of the bridge crew. But more than anything, the sadistic Kirk relished sending redshirts to fetch Spock in his quarters. You know, Kirk's idea of a dutch oven is to get Spock alone in the Enterprise elevator, down and sideways to the hangar and back again, that sick fuck.

  24. We need an asteroid in the face, folks. by FreakerSFX · · Score: 5, Insightful

    Seriously...not anything big but something Tunguska sized would do, especially over a moderately populated area.

    We spend peanuts on detecting potential collisions that could be the cause of the next extinction event. Mark my words, there'll be more money spent on earthquake analysis for Haiti and other "sensational" causes than will be spent on detecting PHOs (potentially hazardous objects) in the next 10 years. I am not denigrating the need to spend money on Haiti - that's a tragedy for sure - but when you look at how reactive we are with public money (New Orleans, anyone? Despite warnings, no one saw this coming?) when a much smaller amount spent up-front would potentially save not just a lot more lives but a lot more money....if better building codes had been in force in Haiti - how many more people would have survived? How much money would have been saved?

    I despair for our race. If we saw a dinosaur killer coming and had a program in place already we could probably survive it. Asteroids move slowly but are heavy and require a lot of time/energy to deflect so we would see them early and be able to react...comets move much, much faster but are lighter so presumably if we had the detection gear and a few mass drivers in space already, we could deal with it in a safe time frame.

    So give us our Haiti or Katrina from space, please. Make it hurt but not too much - just enough to wake up the people handing out government cash.

      The chance that the human race will be eradicated due to an asteroid impact within let's say the next thousand years is extremely low. I've once read an article about J. Richard Gott, who applied the doomsday argument / copernican principle to the survival of humanity.
      It's a statistical method that allowed him to predict how long humanity will last, if you know nothing, except for how long it exists already. Well, guess there the problem was that human-made risks are probably increasing and everything goes at a faster pace, so I don't trust this...
      But the risk to get hit by an asteroid probably hasn't changed at all during the last million years, so by knowing, how long ago the last asteroid impact was that had the potential to erradicate the human race, it should allow us to calculate the probabilty to go extinct because of an asteroid within the next thousand years or so, I haven't done it, but I suppose the chance is tiny.

      We take risks all the time, so I think we she focus on those that are high and that we can technically handle. Imho spending billions on some anti-asteroid defense would be too early considering the risk. We most likely have enough time to deal with this.

      Personally I rather believe that the technological revolution and limited resources will be a much bigger problem for our race. Within a rather short time-frame machines will most likely be able to surpass human intelligence, which has an impact on jobs and makes the whole human race rather obsolete from the perspective of such an artificial intelligence.
      So by developing such AIs and letting it make decisions on a big system level for us with the goal to get things done as efficiently as possible, we might really lose control. Guess I don't live long enough to see that. Would be interesting though.

    Scenario 1: Asteroid strike. I defer to NASA JPL, the Tunguska event (100-meter class = ~ 15 mil tons TNT) asteroid occurs once or twice / 1000 years. A 1000-meter class is 1 in 15 million years. An 8000-meter class (dinosaur killer) is 1 in 50-100 million years.

    Scenario 2: Earthquake. San Francisco has an annual forecast of earthquake probabilities, and they predict a 68% probability of a 6.7 Magnitude or greater in the next 30 years. Wikipedia gives a probability scale for earthquakes, where a Magnitude 7 (similar to what struke Haiti) occurs 18 / year. A single 6.7 earthquake (P = 120/year) is equivalent to 16 kilotons of energy, or about 1 Tungaska event (P = 0.004/year).

    Given the disparity in the probability of asteroid strikes (on populated areas, no less) vs earthquakes, it should be no surprise that the world governments believe money is better spent on earthquake prediction and evacuation relief, not on asteroid strike detection. The "bang for the buck" is clearly higher in earthquake spending.
