Rough Science: Week one's challenges are heavily focused on the "exploration" theme. Jonathan's challenge is to make a rover; a remote controlled vehicle that could explore strange new worlds. Iain and Ellen have to use their geological and botanical skills to search for water in the desert. Assuming they find some water, Kathy and Mike are going to have to find a way of purifying it to make it safe for drinking - an essential component for any mission into deep space.
