The Saturn V configuration is shown in inches and meters as illustrated by the Boeing Company. The Saturn V vehicle consisted of three stages: the S-IC (first) stage powered by five F-1 engines, the S-II (second) stage powered by five J-2 engines, the S-IVB (third) stage powered by one J-2 engine. A top for the first three stages was designed to contain the instrument unit, the guidance system, the Apollo spacecraft, and the escape system. The Apollo spacecraft consisted of the lunar module, the service module, and the command module. The Saturn V was designed perform lunar and planetary missions and it was capable of placing 280,000 pounds into Earth orbit.
It took me a few, but the lower version is either an earlier or later version of the same painting. The figure representing James B. Irwin is a repaint. My guess is the image on NASA’s site is later, reworked to give the figure a slightly more dramatic pose. The painting is by a North American Rockwell artist.
ARTIST’S CONCEPT OF THE APOLLO COMMAND MODULE AND SERVICE MODULE DOCKED WITH THE LUNAR MODULE. ONE ASTRONAUT HAS ALREADY BEEN TRANSFERRED TO THE LM AND THE SECOND IS MANEUVERING HIMSELF THROUGH THE FORWARD HATCH CONNECTING THE TWO SPACECRAFT.
