“I told the kids that we get to drive the rover that is the model for the real one, which is so cool,” said Christie. “They’re essentially doing a live simulation of the project they put together. They use the science instruments and tools (on the rover) to determine if there’s water evidence.” At one point, Leah David-Purcell with Avalon Space announced to the kids that the rover had detected evidence of water, but then one of the students stood up to say her analysis showed the rover had detected iron, not water.
