Growing fresh food on future space missions: Environmental conditions and crop management.

•Fresh food can be produced under limited space and energy conditions providing 11 kg m-2 week-1 (leafy greens, herbs, radish, tomato and cucumber).•Applying spread harvest (weekly harvesting the oldest leaves of leafy greens) and increasing plant density increases fresh food production.•The quality of leafy greens often deteriorated at higher light intensities (600 μmol m-2 s-1).•The presented crop growth recipes and management will be applied in a mobile test facility at the Neumayer III Antarctic research station.
