<\/figure>\n<\/div>\n<\/div>\n<\/div>\nAs space travel extends to greater duration and distance, missions may require a propellant refill in space. To achieve this, spacecraft may require larger tanks and efficient refueling along with tanks that have the capability of isolating propellant from ullage fluid (a gas and vapor mixture) during a vent. The goal of this Challenge is to develop a novel solution for the venting of ullage contents from a partially full propellant tank, in microgravity, with minimal loss of propellant. This ullage venting solution would help allow the adjustment of pressure in the receiving tank prior to, during, and\/or after the liquid propellant transfer.\u00a0This Challenge is seeking solutions to propellant tank venting in micro-gravity with minimal loss of propellant. Although all concepts will be considered, solutions that are external to the propellant tank are preferred as they could use existing (heritage) propellant tanks and avoid development costs related to designing and qualifying a new (or modified) tank.<\/p>\n
