Long-term space missions and habitation on other planets are only possible with a life-support system. A biological life-support system should be able to recreate a proper atmosphere, purify water, and sow seeds to produce fresh nutrition for astronauts. Hort.Space aims to investigate how such systems can grow plants under harsh environmental conditions such as the absence of soil, shortage of water and limited space available.The experiment of the ENEA-Biotechnology Laboratory of the Casaccia Research Center, Italy will focus on growing "microgreens" -leafy vegetables that are harvested very young, can be eaten immediately and contain important nutrients. The microgreens will be grown in a sterile growing room inside an inflatable, self-erecting tent using automated processes. The aim is to provide the analog astronauts with vegetables requiring a minimum of human interaction and reducing the supply transportation for long-term missions.
