154: High speed impacts with Dr. Daly

6/30/2019
More
Dr. Terik Daly talks about his experiments, where things hit other things at tens of thousands of miles per hour. These experiments create pressures greater than that at the center of the Earth, and temperatures hotter than the surface of the sun. Dr Daly tells us what it is like to design and witness these experiments, and how he uses them to learn about the solar system.

152: Mysterious iron meteorites with Dr. Chabot

6/2/2019
More
Dr. Nancy Chabot returns to the show to talk about iron meteorites. Iron meteorites, she explains, are cores of small planets that you can hold in your hand. She describes her laboratory experiments which use furnaces, glass tubes, and tiny hammers.

151: Game-changing asteroid images with Dr. Marsset

5/19/2019
More
Dr. Michael Marsset and his collaborators use the world's biggest telescopes to image asteroids. They combine those images with other data to get shapes of asteroids. These results are comparable with spacecraft images, but are much less expensive. Dr. Marsset talks about new discoveries they have made using this technique.

150: Undersea grippers and in-space assembly with Dr. Backus

5/5/2019
More
Dr Spencer Backus talks about his work at NASA's Jet Propulsion Laboratory. He explains the complexities of trying to design hands for robots. An example of a robot hand is the undersea gripper he worked on, which looks like "an angry starfish." He also talks about the benefits and challenges of in-space assembly of spacecraft.

149: Ballooning on Venus with Dr. Izraelevitz

4/21/2019
More
Dr. Jacob Izraelevitz describes how engineers might design a balloon to explore Venus. This work is in the early stages, what NASA refers to as a "Mission Concept." He also explains the challenges of Venusian exploration.

148: Solving an Apollo mystery with Dr. Curren

4/7/2019
More
When taking a sample of the Moon's surface, the Apollo astronauts discovered a sharp transition from powdery soil to harder rock. This transition was entirely unexpected, and remained unexplained for decades. Dr. Ivy Curren talks about an experiment she designed to explain this phenomena. She also tells us about a type of lunar dust formation that scientists call "fairy castle structures."

147: Searching for extraterrestrial life with Dr. Seager

3/24/2019
More
Dr. Seager explains how she and other astronomers are looking for extraterrestrial life. We discuss the Drake and Seager equations. We also talk about how astronomers might be able to detect life by measuring chemicals in distant planet atmospheres. This episode is related to the March 2019 National Geographic cover story, "We are not alone."
