Did you know that NASA collects all kinds of data about our world? You can learn about clouds, trees, weather patterns, planets, moons, deep space and more. And the cool thing is all of this data is open to the public.  Cindy Chin, NASA Datanaut, joins us for an exciting and informative chat about ways you can use this data. She also tells us about NASA's Data App Challenge and gives us information about how to participate!
