Our names are Jon, Jessica, and John. Our mission was to see how much oxygen was in the rock, see if there was any fertile soil for seeds, and see if we could make concrete from the rock so people could someday build buildings on Mars. I think we did a good job building it. We had an x-ray diffractometer to see what elements are in the rock. We also included a module to plant and care for seeds in soil samples. We also have cameras and a transmitter. The rover should be able to operate on Mars for at least a year.
