Mass gauging of fluids in space systems (such as propellant tanks in upper stages and satellites, or life support systems) is a challenging task due to the absence of buoyancy. The vast number of possible liquid–gas configurations makes some curren

A critical issue in future long-term space exploration missions is the storage and management of cryogenic propellants. Storage tanks are exposed to extreme temperatures and radiation, which can generate hot spots on the tank internal walls even with

An efficient long-term storage of cryogenic propellants is a challenge for future space exploration missions. The vapour bubbles formed as a result of boil-off in the tank walls can generate foam structures, which could be hazardous in different oper
