The Ancient Snows of Mars
When she was learning to forecast the weather in Hawaii, Brown University grad student Kat Scanlon didn’t suspect it would help her uncover evidence for rain or, more likely, snow that helped shape the surface of Mars billions of years ago. Emily Lakdawalla is happy to see Curiosity burning up the meters on the red planet. Bill Nye attended his first NASA Advisory Council (NAC) meeting. Bruce Betts will open up the night sky and help Mat give away the NEW Planetary Radio t-shirt.
