To increase the possibilities for humans to explore space, the development of bio-regenerative life support systems is essential: these systems must fulfil all human needs to sustain a sufficient living condition. In this contest, a greenhouse module is the fundamental part of every concept for a stable and independent base in future space missions. Indeed a greenhouse can (re-)generate essential resources for humans by closing different loops within a habitat, like waste water recycling, CO2 reduction, food and O2 production.
Following this aim this feasibility study has been carried out to investigate and develop the characteristics of a greenhouse module for a future lunar base. This project has been coordinated by the German Aerospace Center (DLR) and it is embedded in the MELiSSA framework of ESA research projects.

CASE STUDY
This work presents the CFD model of an axial piston pump and compares it to a validated 0D model. The main objective of this study was to analyze the flow field inside the pump, focusing on the aspects that involved the main inner volumes, such as the filling and emptying dynamics in the piston chambers and the flow field inside the ducts.
