Episode 20 — Wet Mars / White Mars
There have been a number of hypotheses / theories trotted out over the years in an effort to explain the role that water has played (if any) in the history of Mars.

Between discussions of global climate change, and the ever-rising cost of energy, people are starting to take a long, hard look at the costs of lighting — both financial, and ecological. Listen in to this episode, and I’ll attempt to (ahem…) enlighten you on the history and potential future of this technology…
