We have robotic rovers driving around Mars and sending back spectacular images and data right now, but how far away is the little red planet from Earth? At its closest recorded distance, Mars was 56 million km away, which in galactic terms is nearly nothing. In human terms, however, that's pretty hard to visualize which makes the How Far Is It to Mars website pretty awesome. It gives you a scale representation of the distance between Earth and Mars plus some extra details on your simulated journey between the two planets without requiring you to climb aboard a spaceship. Plus, it's amazingly cool.
