Lonesome Squash writes "BBC reports that scientists have seen a smallish meteor strike on the moon. Impact only equivalent to 70kg of TNT, but still, you wouldn't want to have it land on your moonbase. At that size, it's kind of neat they saw it at all."

      This proves that - apparently - scientists have finally been able to *exactly* reproduce previous empirical results. Just imagine: not only is the impact exactly the same and on the same spot; on top of that the same musings appear on /. !

      What was more interesting from the article, was the toxicity of Moon Dust and the fact that it's highly abrasive, sticks to everything and gets into everything because it's so light.

      Seems back when the contest was announced for an autonomous robot to pick up regolite having to contend with the dust should be the greatest consideration.

    There is an urban legend that at one point, the US Department of Defense actually wanted to NUKE the moon. I think the idea was supposedly that they would nuke a point on the moon that would appear to be one of the edges of the moon, as viewed from Moscow, so Muscovites (including the KGB) could actually see the blast with the naked eye. This was, of course, to be a demonstration of American military might designed to impress and frighten the USSR.

    Can anyone comment upon the truth (or lack thereof) of this particular rumor?

    Don't you love cool images that make you say "wow!" and have a tiny caption at the bottom, saying:

    The NY City subway drivers union filed a complaint against whomever is hurling rocks at the moon, claiming they're just trying to biggyback on the success of their recent strike.
    Intelligent Rock Hurler was not available for comment. His coworkers who plot out the precise trajectories of rocks that result in these strikes also refused to talk to our reporters.

    Now, I am no astro expert but I *think* I have the answer to this one:

    However, as Nasa plans to return to the Moon by 2020, the agency says it needs to understand what happens after lunar impacts in order to protect astronauts.

    I am guessing that there will be a crater of some sort after the impact. Maybe some floating dust. That sort of thing.

      Dust doesn't float very well in a vacuum. In fact, it doesn't float at all. Dust particles created by the explosion will follow ballistic trajectories just like those of the larger fragments. This is important because while you are unlikely to be hit by a large chunk if you're kilometers away 1000 m/s dust could do a lot of damage.
      • Dust doesn't float very well in a vacuum . . .

        I think it would look something like "floating" where the dust particles collide with each other an are sent off in new directions. This would simulate the floating phenomenon in areas where the concentration of dust is sufficiently great.

        Your point about the 1000 m/s dust made me wonder what the escape velocity is on the moon. I did a little googling, and that number appears to be around 2400 m/s. So I guess the good news is there's an upper limit to the

        • So I guess the good news is there's an upper limit to the speed of the dust you'll get pummelled with on the moon from meteorite-ejected debris.

          You mean, if you are shielded from dust on ballistic trajectories? The stuff ejected sideways will travel for some distance, influenced by the gravitational pull of the moon, before escaping.

      • Actually, IIRC, lunar dust tends to hover over the regolith due to some combination of the low gravity and static charges in the dust.
    • Watching the moon is no doubt useful, but to prepare for protecting astronauts against meteor strikes? That seems like a waste of time. I doubt there will be colonies on the moon in the next 100 years and even then, the cost of building a structure that can withstand the force of 70KG of TNT seems unreasonable. If we do live on the moon, it will be a bare bones outpost and the people that go there will be cowboys with little concern for death.

    • The so-called explosion wasn't even "NEAR" moon-base alpha, was far away on the dark side at several of the the nuclear waste disposal and storage facilities. As I recall, it took the better part of an hour by Eagle landers to reach it. This safety measure protected the residents of Moon Base Alpha even in the worst-case scenario that occurred in '99

      Furthermore, It's minute long spontaneous ignition (caused by improper management of the facility and not following the safety specifications) was hardly an exp
  • We know the moon gets struck often, or atleast, that was the thinking when I was in middle school, and that the Earth's atmosphere protects us from similar events.

    What I would like to know is, had this same object entered Earth's atmosphere, would it have made it to the surface or burt up? How much atmosphere (as a percentage of Earth's where Earth's = 100%) would be required to "protect" surface objects from significant damage?

    • Howstuffworks.com has some neat pointers:

      It turns out that what these meteoroids lack in mass they make up for in speed, and this is what causes the flash of light in the sky. Meteoroids enter the atmosphere at extremely high speeds -- 7 to 45 miles per second

      So how big does a meteoroid have to be to make it to the surface of the earth? Surprisingly, most of the meteoroids that reach the ground are especially small -- from microscopic debris to dust-particle-size pieces. They don't get vaporized becau

    This isn't the first time that people have seen meteors hitting the moon. In the 1500's I think it was, some monks in Europe saw what may have been a meteor/asteroid hitting the moon. It was mentioned in one movies/episodes of the Cosmos series. Though I have heard that some people think that it was just a metor breaking up in the Earth's atmosphere and that it just appeared to be over the moon because of their position. Also, some time around the 50's I think(either in the 40's, 50's, or 60's I think I'm not sure), a Japanese scientist saw a small flash of light that was almost certainly a meteor. I almost think that he had a picture of it as well, though I'm not certain.
