5 EASY FACTS ABOUT PET HEALTH MONITORING DEVICES DESCRIBED

The S-IVB also continued to thrust at a low level by venting gaseous hydrogen, to keep propellants settled in their tanks and forestall gaseous cavities from forming in propellant feed lines. This venting also maintained Risk-free pressures as liquid hydrogen boiled off while in the gas tank. This venting thrust simply exceeded aerodynamic drag.[ci
