John Batchelor and I welcomed back Dr. David Grinspoon to discuss the Perseverance rover now on Mars going through its "shakeout" period.  We talked about the benefits to having nuclear RTG power plus we talked about the many rocks seen in the early photos being sent back to Earth.  Dr. Grinspoon talked about this being a river bed, once a lake and the likelihood of finding sedimentary rocks that might show indications of past life.  Dr. Grinspoon also mentioned the possibility of volcanic material being discovered and examined.  We talked about the pictures being sent back, the color of Mars and the microphone now picking up the sound of wind on Mars for the first time.
