Dr Morgan Cable is a planetary scientist and astrobiologist at NASA's Jet Propulsion Laboratory. Her work is primarily focussed on developing technologies and instruments for spacecraft searching for organic molecules and biomarkers in our solar system. She was the Assistant Project Science Systems Engineer for the Cassini Mission, and is currently working on numerous projects to Europa and Enceladus.
Ed and Lucas caught up with Dr. Cable to discuss the exploration of the Saturn system, the Jupiter system, Mars, Iceland and the search for life. Dr. Cable's Twitter handle is @starsarecalling. For more information about the projects we talked about, see NASA's pages for Cassini, Europa Lander, Mars 2020, and Wikipedia's Enceladus Life Finder page.

00:02:06 A study finds that smaller dogs lift their legs higher when they pee. Could they be lying, and trying to fool other dogs?
00:09:30 After a delayed first attempt, NASA's Parker Solar Probe has been successfully launched on a course for the Sun. This will be the fastest spacecraft ever made, and will get up close and personal with our nearest star. For more on solar research, listen to our interview from last year with Professor Lucie Green.
00:20:21 Geologists have been studying tiny grains found in a Russian meteorite. They've found a new mineral, that they call uakitite, which has never before been found on Earth.
This episode contains traces of National Party of Australia deputy leader Bridget McKenzie daring to say "the C-word".

00:02:23 The government of Sierra Leone has announced the discovery of a new species of Ebola virus. Fortunately there's no indication that it's spread to humans yet, but that could be just a matter of time.
00:10:23 Hurricanes Irma and Maria wreaked havoc on the Caribbean, causing extensive damage and hundreds of deaths. But it did provide a rare opportunity for a team to study how natural disasters affect the evolution of some small tree-dwelling lizards.
00:16:52 Researchers are insisting that the hybrid cross of a melon-headed whale and a rough-toothed dolphin that was discovered in Hawaii is not a "wolphin". So of course, everyone's calling it a "wolphin".
00:23:08 For the first time physicists at the Large Hadron Collider have accelerated atoms at near the speed of light. Usually the LHC fires sub-atomic protons and atomic nuclei, so this is a big step up and could herald a new branch of particle physics exploration.
This episode contains traces of astrophysicist Neil deGrasse Tyson talking with Melissa Francis about the newly announced Space Force on Fox Business.

00:01:22 The longest lunar eclipse in 18 years gave viewers in much of the world a stunning spectacle - a blood red moon.
00:03:08 Radar data from the Mars Express probe has revealed a large lake of liquid water beneath the red planet's surface.
00:14:49 CRISPR is a defence mechanism used by bacteria against viruses. And it's pretty good - but it has one major weakness that viruses exploit.
00:22:22 Researchers at Carnegie Mellon University and Yale University have now made a significant breakthrough - by using gene editing to treat a genetic condition in utero. In mice.
00:30:15 Dr Jurgen Otto loves peacock spiders - a lot. And his passion has let him on a journey through southern Western Australia in search of a tiny (but cute) spider he saw 23 years ago. Check out his site: Peacockspider.org
