Rovers, Helicopters, and Ancient Martians: Why We Explore Mars
Following a wonderful introduction of our speaker Andrew Fraknoi by our own Gary Latshaw, Fraknoi shared his passion for Mars and why we explore.  His presentation included beautiful color images from the latest space probes.
It was riveting and well worth taking in if you missed it.  Click here for his fascinating presentation.
Fraknoi explained how evidence now leads us to understand that ancient Mars was a world somewhat like Earth, with lakes, rivers, and possibly the stirrings of life.
