Join host Ira Flatow and guests for a discussion about space exploration in the wake of the space shuttle Columbia disaster. How will the loss of Columbia affect space policy in the United States? Should NASA put more emphasis on unmanned projects? Should we focus on Earth, or go to the stars? We'll also get an update on the investigation into the cause of the shuttle's break-up.
