    Meteor expert Clark Chapman and former astronaut Rusty Schweickart urge U.S. military to re-initiate sharing of satellite detections of meteor impacts:

    Russian Meteor Fallout: Military Satellite Data Should Be Shared.

    From links in the article, the military formerly did share this information but the policy was changed in 2009. This is important because the satellites reportedly have the capability to detect meteors down to 1 meter wide and below. This would well have the capability to determine if close asteroid flybys result in increased meteor impacts.

    Seems like pieces of meteorites are worth a pretty dime, maybe upwards to 40x their weight in gold. If you came across a meteorite piece, would you keep it or sell it?

    Although I can see the point of owing something rather rare or unique, but a piece of rock or chunk of metal? No question - sell it! Let it sit on someone else's shelf or coffee table.

    No, you should keep and copy it, with minor shape changes and sell your forgeries. If you don´t have a real meteorite, go to an old iron blast furnace´s "slag heep" and pick up small pieces with some bubble holes in them. If you must break up a big peice, but sure to remelt the sharp edges and surface of the break.

    I found a piece of apparent slag near the driveway and still wonder if it really was a little meteorite somehow. I'm not sure where it is now, since that was many years ago.

    If you live where it snows and they put "cinders" on the icey road and you found it less than a week or two after that that was , probably no.

    I do live where it snows, yet this thing that I found was like a glob of melted and cooled iron. It wasn't flattened, though, like I would expect if molten iron dropped on the ground.
