back to article Tunguska object came from Mars say Russian boffins

Russian boffins have floated the idea that the Tunguska object, a meteorite that flattened swathes of Siberia in 1908, may have been a chunk of Mars. The Tunguska event is considered history's largest recorded meteorite impact. Controversy surrounds whether the object was a meteorite or comet, and whether the object hit the …

    Where's the kaboom? There was supposed to be an earth-shattering kaboom!

      No boom today.

        Very apt sci-fi reference! Thank you Vince.

    Chances of that?

    Million-to-one, I'd say!

      Million-to-one chances crop up nine times out of ten.

    gravelite sandstone (98.5% SiO2)

    One big enough to be a Tunguska candidate Is not likely to survive being fired from a cannon on Mars or being thrown up from a meteorite impact there either. Well not to make it to earth in one piece without some serious shepherd moon of its own.

    re: whether Martians threw it at us. And why.

    ... perhaps it was just a dramatic skycrane failure?

    Volcanic plug

    Considering volcanoes on earth loft some rocks a fair distance how much would it take to send a big rock out of the gravity of Mars?

      The force that would send it straight up at > 11,200 mph.

        5km/s on Mars iirc.

        I suppose it's even a little easier if you did it from the top of Olympus. I don't think Olympus is that dense, I could well be wrong though. One course on "the Solar system" 13 years ago at uni isn't a lot to go on.

    Alternative theory:

    Mars has been bombarded with so many tunguska meteorites that its covered in the same stuff.

      Have you been watching those dreadful adaptations of superb pulp-sci-fi novels that have been being broadcast over Christmas? ;-)

        Why do you think it was dreadful?

          Re: It's BUGS!

          Actually, they weren't that bad... I just got upset because I read the whole series of books back in the 80s/90s and the films are not a patch on those. But the films do stand up reasonably well in their own right - well, the first one, anyway. Did they make sequels? I seem to recall seeing a second one.

            Love the first film (and subsequently read the book it was based on), but the sequels are absolutely dire.

              Yes, they made sequels, but they fall into the same category as the sequels for The Matrix, and Highlander.

              Ignore them and your memory of the first movie will remain unsullied.

              What was your opinion of the book and how it was translated to film? I must admit it was many, many years ago that I read Heinlein's works (the ones in our local library anyway).

    I don't believe it for a moment. Readers of Stanislaw Lem know that it came from Venus.

    If it was the Martians, then their aim was off. They missed France by thousands of miles.

    How to spot junk science:

    1) the paper makes spectacular claims about something spectacular.

    2) the paper is an analysis of objects which no-one but the author has seen or think exist.

    3) the paper has not been published.

    But they mixed up metric and imperial units....

    Throwing rocks in a lake

    "If proven, the next question must surely be whether Martians threw it at us. And why."

    You know how it's fun to throw rocks at a lake surface to see how far you can make them bounce?

    From a martian's point of view, the closest lakes around are those of water on Earth, and the methane ones in Titan. Earth is only about half as far away as Titan...
