What was the Saturn C-8?
The Saturn C-8 was the largest rocket in the Saturn series ever to reach the design stage. It was a potential alternative to the Nova rocket, designed for a direct-ascent lunar mission if NASA chose that approach.
Questions about Saturn C-8
Short answers, pulled from the story.
How many F-1 engines did the Saturn C-8 carry on each stage?
The Saturn C-8's first stage (S-IC-8) and second stage (S-II-8) each carried eight F-1 engines. The standard configuration for those stages used five engines each.
Why was the Saturn C-8 never built?
Two factors stopped the Saturn C-8 from being built. The Michoud Ordnance Plant selected in September 1961 could not accommodate a vehicle 40 feet in diameter, and the lunar orbit rendezvous approach approved in 1962 removed the need for a rocket of the C-8's scale.
What was the role of the Michoud Ordnance Plant in the Saturn C-8 story?
On the 7th of September 1961, NASA selected the Michoud Ordnance Plant near New Orleans as its production facility for Saturn first stages and larger vehicles. The factory roof height made it impossible to build a 40-foot-diameter vehicle like the C-8 there, with four or five engines and a 33-foot diameter being the maximum the plant could accommodate.
What launch vehicle replaced the Saturn C-8?
The Saturn C-5, developed under the designation Saturn V, replaced the C-8 concept. Its payload capacity was sufficient for the lunar orbit rendezvous mission NASA adopted in 1962.
What was the direct-ascent method of lunar exploration the Saturn C-8 was designed for?
The direct-ascent method involved sending a spacecraft from Earth directly to the lunar surface without stopping in lunar orbit first. The Saturn C-8 was sized for this mission profile, which NASA ultimately chose not to pursue in favor of lunar orbit rendezvous.
