'Cave entrances' spotted on Mars

The caves may be the only natural structures capable of protecting primitive life forms from micrometeoroids, UV radiation, solar flares and high energy particles that bombard the planet's surface.

The spacecraft spotted what seemed to be vertical "skylight" entrances to caves below the surface.

The odds are these features are natural, but I'd recommend taking a careful look.
