The Bad Astronomer points out a really cool image of Phobos, one of Mars's two moons:
They were taken by the Mars Express probe, which will be doing a series of flybys of the two moons, Phobos and Deimos. The lines are cracks in the moon.
Phobos is somewhat potato-shaped and about 22km (14 miles) on a side. it's weird and cool; I'll post more about it later.
