Back To The Future

Editor's note: As NASA moves ahead with designing the second stage of the CLV (Crew Launch Vehicle) which will feature a single J-2x engine, people at several NASA centers have been looking back at the last time NASA flew an upperstage with a single J-2 engine: the S-IVB.

The S-IVB was used on both Saturn 1B (second stage) and Saturn V (third stage) launch vehicles. Interestingly, the S-IVB was what Apollo used to perform the mission role that the new EDS (Earth Departure Stage) is being designed to do. Stay tuned.
