• D-Brief reports on one new compelling theory suggesting that the Martian moons of Phobos and Deimos are not captured asteroids, but rather debris cast into orbit by a big impact on Mars.


• Starts With A Bang's Ethan Siegel notes that bits of Mars tossed off by asteroid impacts have made it as far as Earth.


• Bad Astronomer Phil Plait notes the strange fossae of Mars, mysterious cracks in the planet's surface.


• D-Brief notes a new paper suggesting that, in Mars' relatively warm youth, life might well have found a home in its crust for hundreds of millions of years.
