Sunset on Mars.

How freaking sweet is this?

from NASA

On May 19, 2005, NASA’s Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars. This Panoramic Camera mosaic was taken around 6:07 in the evening of the rover’s 489th Martian day, or sol.

I think Mars Exploration is about the damn coolest thing happening right now.
