and now a dash planet. we know it opposite had a frozen ocean but the hope is radio activity inside the planet melted the ice, and if water equals life, we want to know if there is or was life and, those bright spots on the surface? the speculation is they could be buried ice gushing guise geysers even alien space photographs. the next month we'll be in a blackout because the spacecraft is on the dark side of the planet. then we should gather data. the dawn spacecraft ises the size of a big rig truck and it might be scout thing planets for a long time. it run's an ion propulsion system and gets a billion miles a gallon. bottom line nasa is very excited about this mission.
