Another big hunk of delta-V. You don't need to land on it-- just throw something at it to knock off chips, a-la Deep Impact. Angle the impact right, and you should throw some of them towards Earth. And some might be at an angle/velocity that they could orbit (you'd have 24 years to plan the pool shot necessary). And if chunks of it enter the atmosphere, what of it? They probably wouldn't be any bigger/more dangerous than the usual meteorites entering the atmosphere (and might even survive to be collected then). Given a quarter century and the resources of all interested space-aware nations (those with a space program and those wanting a space program) I do not see any reason something could not be put into the right orbit to knock off a chunk or two. And wouldn't it be worth the relatively small cost to orbit a satelite for the chance of getting a pristine asteroid sample? ______________________________________________ Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
