Mars will get the newly dubbed "Dimorphid" meteors first but Earth is not too far behind.

Scientists have traced six meteorites to their original craters on Mars, providing unprecedented new insights into their origins.

A fringe theory called "panspermia" suggests that lifeforms can spread to new planets by hitching rides on meteors. New research lays out a roadmap for finding where these hypothetical, planet-hopping aliens may reside.
