Scientists have detected an ancient migration of the Mars ice caps. Because of Mars’ eccentric orbit, winter may last up to five weeks longer at one pole than at the other. As the red planet progresses through the millennia (imagine a top that spins, but also wobbles) longer winters shift to the opposite hemisphere. Over a period of 50,000 years, ice at one pole would evaporate and refreeze on the opposite side of the planet.
