We welcomed both Dr. Karen Jonscher and Dr. Virginia Ferguson to the program to discuss their research on mice livers from aboard the space shuttle suggesting that long duration spaceflight might cause liver disease in the astronauts. Our guests explained their research and their findings and what it might mean for long duration HSF, particularly to Mars. They also explained why this research is important.
