pH Wheel

This rover wheel has a small layer of titanium surrounded by a much larger layer of aluminum. This is for durability. Titanium is very strong, but too heavy to be the main component of the wheel. The rover will have six wheels for balance and to maneuver easier. There is no center to allow the wheels to expand and contract. This will help the rover traverse the tricky terrain. The rough surface of the wheels will also help with traveling over the rocks and sand. The wheels can also test the pH level of the soil. The jagged edges of the outer layer will test the soil. The pH level is important to know because it determines nutrients that plants need to grow. This will help with putting colonies on Mars. This rover wheel is durable, provides balance, and assists with important research.
