Mars without Martians

At 1.4 miles from the sun in our scale, Mars is about half the size of Earth and has two moons that are too small to be presented in this display.

The angled post in the crescent, as we were learning, represents the planet’s tilt in its orbit, the major factor that gives us our seasons.

By this point in our drive, we were beginning to catch on to what we were looking before rather than passing by and having to circle about. The game now became who would spot the next stop first.
