Moon Rocks Still In Demand After Almost 40 Years

During NASA's Apollo missions to the moon, roughly 842 pounds of rocks were collected from the lunar surface. Scientific demand for the rocks has always been high, and a review board tracks and sends out hundreds of samples each year, even now, decades after the rocks were brought to Earth. They've provided researchers with a wealth of information about the entire solar system. From the NYTimes: "The samples have confirmed that asteroid and meteor impacts, not volcanism, created the vast majority of craters that define the Moon's topography, while a constant barrage of meteorites, micrometeorites and radiation melted and pureed the bedrock to create the blanket of fine-grained soil and dust -- known as regolith -- that now cloaks the lunar surface. And knowing the ages of Moon rocks, which can be computed to within 20 million years, has enabled scientists to establish a baseline that allows them to date geologic features throughout the solar system. The surface of the Earth, one of the solar system's youngest topographies, is constantly changing, as it is faulted, folded, shaped and reshaped by eruptions, earthquakes and erosion. By contrast, the Moon is as old as it gets."

    But the article makes us believe that due to changes on the earth's surface, matter here is not as useful as that on the moon.

    You need a definite article in front of those nouns. Please learn English properly for the sake of everyone.

    Even on the Moon the Grammar Nazis will still find you.

    Have you considered that perhaps the OP's native language was, in fact, other than English? The beauty of English is that you can mangle it in every which way and still be perfectly understandable. You understood him fine. Otherwise you'd not be able to "correct" his post. You're just a jerk. I bet you're a wikiadmin in your spare time -- if not, consider it, you'd fit right in.

    If there's ever a one-way spaceship leaving for the Moon, be sure and be on it. Please leave the planet for the sake of everyone.

    If people were to believe you, many would argue there should be a giant new crater thanks to Bush.

    Ooh. Wait, wait! I screwed up and got myself back to positive karma. I want to get in on this troll hunting!

    See, my theory is this. My karma is irrelevant. Utterly, completely irrelevant. Seriously - it's just some stupid number on a website. No bearing on me or life in general.

    However, it's nice to have some people go through and mod articles so I don't have to spend time reading everything. Unfortunately, the mod population contains numbers (apparently significant) of people who are utterly unqualified to do so in any reasonable manner.

    That's where we come in. By tossing in some posts like this and the above, we burn mod points (a limited resource) of people who are too stupid to use them for their intended purpose. Thus removing morons from the mod pool, at least where it counts. Otherwise these modtards notice the real posts, and that's not helpful.

    Hint: sometimes it helps to talk about your turd collection.
