The team behind Guardian Radio just posted that they are looking for questions from the Destiny community to pose to Craig Hardgrove, a member of the Mars Curiosity Rover science team. Craig actually visited Bungie back in January and Bungie tweeted a picture of him at their studio. The post for the questions can be found here. If you ask me that is pretty sweet! The episode is supposed to be released Tuesday. I wonder what Destiny nuggets they can dig out of him?
