John Batchelor and I welcomed back Dr. Marc Rayman of JPL to pay tribute to the Dawn Mission from concept to launch to Vesta, then Ceres, and then the final parking orbit above Ceres as the Dawn mission concluded.  During our two segment discussion, we covered the Delta 2 launch, the use of Ion propulsion to Vesta that made the mission possible, plus how they operated Dawn when all the flywheels gave out and they needed to control Dawn through creative thruster use.  We also summarized scientific findings and discoveries for Vesta and Ceres of which there were many.  In addition, so much data still needs to be evaluated that we will be learning more about Vesta and Ceres for years if not decades to come.  I'm sure you will find what Dr. Rayman had to say about Dawn, Vesta, and Ceres most interesting.  I am sure we will continue hearing about Ceres and Vesta discoveries as the information is evaluated on an ongoing basis.

You can email Mr. Batchelor or Dr. Rayman through me at Marc can also be reached through his JPL website page.
