    Gravity Assist: Why Icy Moons are So Juicy, with Athena Coustenis

    A great era of exploration of the icy moons is about to begin. Athena Coustenis of the Paris Observatory talks about missions to the icy moons of the outer solar system and international collaborations with NASA and ESA.

    Gravity Assist: Is Artificial Intelligence the Future of Life? With Susan Schneider

    Gravity Assist: Is Artificial Intelligence the Future of Life? With Susan Schneider

    If astrobiologists find life beyond Earth in the solar system, it will most likely be in the form of tiny organisms called microbes – nothing that would talk to us.

    Gravity Assist: Our Sun, Our Life, with Vladimir Airapetian

    Gravity Assist: Our Sun, Our Life, with Vladimir Airapetian

    Vladimir Airapetian, scientist at NASA’s Goddard Space Flight Center, explains what researchers hope to find as they gaze beyond our solar system.

So good! I look forward to each episode released and can’t get enough. It’s fascinating, well made, and the topics are well translated so anyone can understand.

Dr. Jim Green is all of us

Dr. Jim Green is the Chief Scientist at NASA, so it stands to reason that he knows an awful lot about most topics related to space. But as the host of Gravity Assist, you'd think he was an eager grad student, because he has a way of asking questions that help make even intricate topics easily understood by laypeople. I love his endless enthusiasm, and his boundless desire to share the beauty of space with the rest of us. I'll bet that he has been the "gravity assist" that launch the careers of many space scientists.
