First we return to JPL for an update on the Mars Helicopter that has just been attached to the belly of the 2020 Mars Rover. Then it’s across the pond for a review of the amazing science coming from the Rosetta mission that spent years exploring comet 67P/Churyumov-Gerasimenko. We wrap things up with another What’s Up view across the solar system and beyond.
