152: Mysterious iron meteorites with Dr. Chabot

Spacepod ·

2019/06/02

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

Spacepod ·

2019/05/19

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.

148: Solving an Apollo mystery with Dr. Curren

Spacepod ·

2019/04/07

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."

143: Telescope robots with Dr. Ramirez

Spacepod ·

2019/01/27

Dr. Solange Ramirez returns to the show to talk about her new position as Project Manager of the Sloan Digital Sky Survey V. Amount other things, the project will study over six million stars and how black holes change over time. These millions of measurements will be made using a robotic telescope system that is currently being built.

142: The biggest clock with Rob Seaman

Spacepod ·

2019/01/13

Rob Seaman of the Catalina Sky Survey talks about time, and why you need to know the time to discover asteroids and comets. He explains how he installed a highly accurate clock, and makes the case that "natural time" is better than "cold, heartless atomic time."
