WASHINGTON (Reuters) - A study of meteorites chipped off the surface of Mars suggests the planet has been frozen for 4 billion years and probably never had the warm wet conditions that could have given rise to life, two researchers said on Thursday.

Scientists have long thought that the Red Planet was once temperate enough for water to have existed on the surface, and for life to possibly have evolved. But a new study by Caltech and MIT scientists gives this idea the cold shoulder.
