Master of Disaster Mika McKinnon talks about how she injected real science into the sci-fi series “Stargate”. We discuss how she balanced accuracy and entertainment, and how she influenced the way scientists were portrayed on that show.

Jan Chodas stops by the show to talk about her experience working on several pioneering NASA missions, including Galileo, Cassini, the Spirit and Opportunity rovers, and Juno. Note: this was recorded before Juno successfully entered into the orbit of Jupiter.

Professor Rita Economos talks about her research into magma on Earth. She recounts some of the adventures she’s had searching for rocks, and explains why Earth’s volcanoes appear to be unique in the solar system.

Dr. Rachael Beaton and I try “Grass Jelly Drink” and talk about one of the major fundamental constants of the universe; the Hubble Constant. She explains what it is and why she and her colleagues are trying to measure it better than it ever has been measured before.

Dr. Solange Ramirez visits the show to talk galaxies, supermassive black holes, and the gravity that ties them together.
