124: Searching Antarctica for meteorites with Dr. Cohen

  Dr. Barbara Cohen  returns to the show to talk about meteorite collecting in Antarctica. These trips, which involve weeks of camping on the ice, provide invaluable scientific samples. She talks about what it's like to search for the rocks that "don't belong" in the frozen desert.  NASA put out a great article on her work as well, read it  here ! Also check out Dr. Cohen's  Wikipedia page .

121: Solar storms with Dr. Janvier

  Dr. Miho Janvier  talks about her work studying solar storms, and tells us about the ways these storms have impacted humans in the past. She explains why they are challenging to model and says why she's interested in "garbage" data from planetary missions.  Folllow Dr. Janvier on  Twitter , and watch her  TED talk !

117: Guardians of (a very small part of) the galaxy with Dr. Fast

  Dr. Kelly Fast  tells us about the  Planetary Defense Coordination Office , which finds asteroids before they find us. She talks about a recent exercise involving the tiny asteroid 2012 TC4, where asteroid hunters across the world coordinated to observe this object on a recent fly-by. We also talk about ‘Oumuamua, the first interstellar asteroid ever discovered.

114: The densest stuff in the universe slamming together at the speed of light with Dr. Kanner

  Dr. Jonah Kanner  talks about  LIGO ’s spectacular detection of two neutron stars merging together. This merger was not only detected by gravitational wave detectors in the US and Europe, it was also seen by many telescopes across the world and in space. This new discovery will help unlock many longstanding mysteries in astronomy and fundamental particle physics.

113: Belt and suspenders spacecraft with Julie Webster

  Cassini ’s spacecraft operations team manager,  Julie Webster , stops by the show to reflect on Cassini. We chat about the time Cassini dove through Titan’s atmosphere, how Julie monitored thousands of channels of telemetry at once, and how she’s happy that she doesn’t have to spend her time thinking through worst-case scenarios (or “awfulizing”) now that the spacecraft is no more.
