Space exploration was in its early years when Gerry Anderson's Fireball XL-5 premiered in England in 1962.
The third series to employ Anderson's Supermarionation process, Fireball was headlined, if you will, by Captain Steve Zodiac. Unfortunately, the series would only last one year, 39 episodes, before being cancelled. Despite this, NBC acquired Fireball to fill a space on their Saturday morning schedule from 1963-5, and even with the low episode order, I think it spent some time in syndication after leaving NBC. I barely remember the show myself, so there won't be a rating.
Just the same, here's a sample clip, with the open of an episode, followed by the closing credits. Don Spencer sings the theme song.
