In addition, new observations have revealed that the diminuituve dimensions of both satellites are determined by their brightness. There was also the possibility that a European spacecraft called Europa may be tasked with building a robotic vehicle similar to the Viking, Mars Pathfinder, Spirit, Opportunity, and Curiosity rovers.
