The Shadows of Vesta

Check out this spooky picture of the giant asteroid Vesta, as taken by the Dawn spacecraft. Pictures like this send shivers down my spine, not only because it shows the deep shadows of a lifeless eerie rock but also   accurately captures the static silence of space.

Dawn is in the process of leaving Vesta - a dwarf planet in the asteroid belt between Mars and Jupiter - to travel to another huge asteroid called Ceres. What's interesting bout Dawn is that it uses xenon ion propulsion, which I didn't even realize was a live technology. You hear a lot about them in SciFi, but now they're in use in everyday life. Amazing.
