Dinosaur asteroid 'sent life to Mars'

The asteroid that wiped out the dinosaurs may have catapulted life to Mars and the moons of Jupiter, US researchers say.

They calculated how many Earth rocks big enough to shelter life were ejected by asteroids in the last 3.5bn years.

The Chicxulub impact was strong enough to fire chunks of debris all the way to Europa, they write in Astrobiology.

Thousands of potentially life-bearing rocks also made it to Mars, which may once have been habitable, they add.

"We find that rock capable of carrying life has likely transferred from both Earth and Mars to all of the terrestrial planets in the solar system and Jupiter," says lead author Rachel Worth, of Penn State University.



Now, this is one crazy theory :P . I wonder whether they can find any direct evidence of it on Mars or the Jovian moons?

I doubt that is true, it sounds insane. I suppose it could be possible, but unlikely.

If this is true though...I'm not quite sure there would even still be life on Mars.

Yeah, I think it's doubtful that there would be any remaining life on Mars descended from this life. It might have left behind evidence of some form, though.

(Of course, there's already some evidence that this is how life originated on Earth....)
