NOT KNOWN FACTS ABOUT APOLLO 3.5 BLUE PLUS PROCESSOR

The S-IVB also ongoing to thrust at a very low level by venting gaseous hydrogen, to help keep propellants settled inside their tanks and forestall gaseous cavities from forming in propellant feed traces. This venting also preserved Secure pressures as liquid hydrogen boiled off in the gas tank. This venting thrust very easily exceeded aerodynamic
