Beneath the Blowing Sands

Mars is a dead planet, a desert ball. It is not quite certain that it has always been so, but if there is life there now it is being very coy – various missions including the Mars Rovers have found no sign. Perhaps one day humans will land there, with sealed spacesuits standing in for the Earth’s protecting atmosphere. For now, Mars spins and tumbles around the Sun, carrying nothing but its red dust blown by thin winds that nobody will ever feel on their skin. The planet is closer than the Earth to the main asteroid belt, and there are plenty of asteroids that cross its pathway. Collisions are inevitable. So beneath the blowing sands of its deserts there are craters.
