    Was Life on Mars Extinguished Prematurely by a Huge Impact?

    We keep sending missions to Mars with the key objective to search for past or present life. But what if a huge impact early in the Red Planet's history hindered any future possibility for life to thrive? Recent studies into the Martian "crustal dichotomy" indicate the planet was struck by a very large object, possibly [...]

    Also, our moon is said to be the result of such an event, some four billion years ago.

    From this point of view, asteroid impacts are only peanut-events ! At least, as long as they donīt happen during our lifetime
