John Batchelor and I welcomed Dr. Robert Pappalardo, the NASA JPL Mission Director for the upcoming Europa Mission. John started out by asking our guest why the need to go to Europa. Dr. Pappalardo explained the significance of going to Europa, the science that will be done as a result of this mission, the search for life which may exist in the subsurface oceans and more. I asked our guest about the mission's instruments which Dr. Pappalardo then briefly discussed. He also spoke about the need to learn more about the oxygen cycle regarding the possibility of organic molecules. We talked about the Europa mission orbiting around Europa 45 times or so, coming very close to the surface, as it orbits Jupiter since the mission does not have a lander. Bob also spoke to high degree of sensitivity of the sensors and what they can do when they fly very low over the Europa surface. As for travel time to Europa, it depends on the launch vehicle used. Using the new SLS which is under design would take about 3.5 years. Something like an Atlas 5 might take up to 9 years. Please post comments/questions about this program on TSS blog above. You can email Mr. Batchelor or Dr. Pappalardo through me at
