John Batchelor and I welcomed back Dr. David Grinspoon to discuss the new planned missions to Venus plus the new photos coming back of the Jupiter moon, Ganymede.  The photos are being taken and sent back to Earth by the Juno mission.  We started this double segment program by talking about the missions to Venus. Note that Dr. Grinspoon is part of the Davinci+ mission team that has a tentative 2029 launch date.  Davinci + (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging, Plus) is a type of lander but it is an open question as to it being working when it hits the surface of Venus or for how long.  It will be sending back important information on the way down through the atmosphere of Venus.  The Veritas mission, which will likely launch first in 2028 is an orbital mission.  Dr. Greenspoon did explain the instrumentation and science to be done by both missions.  He also talked about the European mission to Venus later on, the EnVision orbital mission. 

The second segment of today's program was spent talking about the new photos being sent back by Juno of the very large moon of Jupiter, Ganymede.  Both John and I asked David many questions about Ganymede along with Juno and even the rings of Saturn.
