That craters on planets (with and without atmosphere) are the result of impacting bolides is probably a myth for most crater types. We know meteorites and asteroids do not impact the surface of the Earth, they already breakup completely in the atmosphere and there is also a coulomb explosion (as evidenced at Chelyabinsk), with a possible bolide to ground electrical discharge.

For airless bodies it is now most likely that charges build up on the surface and can potentially discharge, this already explains moon flashes but could also explain crater formation in the future.

ps. we always assumed craters were made by meteorites/asteroids, this as never actually observed, science needs observation first.

Daniel
