NASA Designs Transforming Rover for Exploring Distant Worlds

One of the challenges of exploring distant worlds is the variety of terrains that a vehicle might encounter there. There could be flat planes, which are relatively easy to traverse in a wheeled vehicle, and there could be steep slopes, which are much harder. That's why NASA is developing a new type of rover that can transform to take a shape most suited to the environment. The DuAxel rover is made up of two individual rovers with two wheels each, both called Axel. Together, the four-wheeled rover can travel across rugged terrain and drive across considerable distances.
