Wormsign

In 1966, the Aeronutronic division of Ford Motor Company (remember the days when automotive companies had important aerospace divisions working on manned spacecraft for interplanetary exploration? Cuz I sure don’t) reported to NASA on an unconventional lunar rover: the Worm. Basically a tube, but with a number of external ring segments, each ring having a flattened “foot.” By undulating the rings (“travelling wave bellows”), the vehicle could trundle along over pretty much any sort of expected lunar terrain. Tops speed would be Dead Slow (5 mph), and probably Deafeningly Loud. But at least it’d be disturbing to watch.

Range was to be 100 miles, carrying a 1000 pound payload.
