Conclusions
DSLS are expected to meet more stringent requirements
Long duration missions will rely on Adv ISS Life Support technologies
Synergistic, multifunctional and closed-loop systems are needed forsustainable life in deep spaceThe ISS and Beyond LEO test beds shall be exploited as supportingplatform for DSLS developmentLong duration testing (on Earth and in µg conditions) is needed to verifylow failure rates and maintainability
