The S-IVB also continued to thrust at a reduced stage by venting gaseous hydrogen, to keep propellants settled inside their tanks and prevent gaseous cavities from forming in propellant feed traces. This venting also managed Secure pressures as liquid hydrogen boiled off from the gas tank. This venting thrust easily exceeded aerodynamic drag.[citat

Wernher von Braun and Other people also experienced programs for a rocket that might have highlighted eight File-1 engines in its initial phase, such as Saturn C-eight, permitting a immediate ascent flight on the Moon. Other ideas with the Saturn V identified as for utilizing a Centaur being an higher phase or including strap-on boosters. These enh
