This week on Blue Dot we talk with award-winning NASA scientist, Fiona Harrison. She is an astrophysicist and chairperson at CalTech as well as Principal Investigator for the Nuclear Spectroscopic Telescope Array — our premier orbiting X-Ray observatory better known as NuStar. We also take a sneak peak at next week's interview with Kenneth Williford - who shares an exciting story of a recent development in his lab at JPL. Finally, we cap it all off with some audio captured over the weekend by Nolan and Dave at last weekend's Dark Sky Festival in Lassen Volcanic National Park.
