Perhaps the "1 megaton" nomer is for what encounters our atmosphere, not necessarily what impacts our surface.

- troels 14y agoThat might be the case, but then it's not really something to be worried about, is it? I mean, then they're basically saying that astronauts on Mars will see shooting stars a bit more often than on Earth.
- debacle 14y agoIt is, because on Mars there isn't an atmosphere there to burn up that 1 megaton asteroid into something more innocuous.
- danielweber 14y agoJust to be clear, Mars does have an atmosphere. It's pretty thin, but it's real enough to provide protection against micrometeorites and some of the radiation. It ain't gonna stop a school-bus sized meteorite, though.
