During our 11 minute plus discussion, John, Bill, and I talked about Comet ISON which is now visible in the sky near Mars. We talked about its Thanksgiving close pass to the sun, its survival probabilities, and why this may be the comet of the century. We also talked about a new report indicating small asteroids such as the one that came in over Chelyabinsk, Russia earlier this year may be more common than thought and may put us at more danger than previously thought. Finally, we talked about the Olympic torch going to the ISS on a Soyuz last night, its upcoming photo op on a space walk and its return to Earth.
