the miniature model of lunarville 7 was built partly out of colanders and mixing bowls. some elements of the puppet set design were recycled from century 21's previous series, "thunderbirds": the moonmobile cockpit incorporated sections of the interior of "thunderbird 4" and the lunar controller's desk was a modification of the glenn field controller's desk from the film "thunderbirds are go" (1966). the moon shuttle cockpit was a re-dress of the martian exploration vehicle interior first seen in "thunderbirds are go" and again in "the mysterons". the moonmobiles influenced the look of the shado moonmobiles in the andersons' live-action series "ufo".
