What are iRings?

A flat tire is always unwelcome, but even more if you are in the midst of roving on the Moon! iRings are specially developed rugged rover wheels made of an outer layer that looks like chain mail, which can be filled whatever material might be available (for instance, lunar soil and rocks). Their sturdy, flexible design allows a rover to drive over rocks, lumps and bumps typical of the extreme terrain found on the Moon.
