From Tuesday Morning Quarterback. This really makes you wonder!
News from Nearby Space: Meanwhile the more researchers learn about asteroid and comet strikes on Earth, these events seem much more common than previously assumed — which is definitely not good news. Last summer, TMQ laid out the disturbing evidence that space-rock strikes powerful enough to cause mass extinctions were not confined to the primordial mists: Something gigantic smashed into the Earth about 10,000 years ago, and there might have been a severe comet or meteorite strike as recently as the year 535. Recently researcher Dallas Abbott of the Lamont-Doherty Earth Observatory at Columbia University has found indications that a huge comet or asteroid fell into the Indian Ocean about 4,800 years ago, causing global tsunamis.
Abbott’s work is especially important because she is studying the oceans, not land. Most of what’s known about past space-object strikes comes from the study of land craters. But three-quarters of Earth’s surface is water; Abbott reasoned that three-quarters of space objects must crash into the seas. Her work suggests a lot of comets and large rocks have hit the seas, many recently in geologic terms. As recently as a decade ago, most scientists assumed that space-rock strikes powerful enough to cause general devastation happen only every million years or so. Now it looks like they are far more frequent. If a rock comparable to the one that struck the Indian Ocean 4,800 years ago struck today in Kansas, half the population of the United States might die. And as TMQ endlessly points out, what is NASA doing about this? Absolutely nothing.
NASA continues to waste about 10 billion of your tax dollars annually on a space station project that had no scientific value, existing solely to justify money for aerospace contractors and staff budgets at NASA manned-flight centers. NASA plans to waste 200-500 billion of your tax dollars on return-to-the-Moon missions that don’t even have a theoretical justification — the sole purpose of return-to-the-Moon is money for NASA insiders. Yet if a comet or large meteor was spotted heading toward our world, NASA could do nothing. And NASA isn’t even researching possible anti-space-rock technology. No agency of your government wastes taxpayers’ money more cynically or systematically than the National Aeronautics and Space Agency. If a big space object strikes the Earth, sending humanity’s survivors back into the Dark Ages, our descendents will consider the present Washington government history’s worst collections of fools for doing nothing while there was time.
Time to get NASA a new focus in my opinion.
What a waste!
