Production of bioactive and particularly carotenoid-rich vegetables as part of Space Life Support System

The future of space missions and extended human presence in space requires the ability to provide proper dietary intake for space travelers with minimal resupply from the Earth, as food and food packaging currently represent a significant burden on space mission consumables (Perchonok et al., ). This is critical for sustaining an optimal nutritional status for space travelers and for mitigating stress effects from long-duration space travel, including weight loss, hematological changes, and space radiation-
