In what sounds like the plot of a Bruce Willis movie — but is in fact a real scientific experiment on a grand scale — NASA is preparing to plow a satellite and its booster rocket into the surface of the moon on Friday morning, to see if there is any sign of water in the two dust clouds created by the impacts.
How useful do you think the results of these impacts will be?
If this affected the tides, it would be a major faux pas for NASA. But I'm no rocket scientist.
You would have to take a gigantic chunk out of the moon to have any effect on tides. Considering that objects much larger than LCROSS and Centaur have hit the moon over its existence, I wouldn't be worried. At all.
