Food technology has evolved considerably, but people still have to feed on fresh food. Astronauts can live with long-term or frozen foods for extended periods of time, but for a variety of reasons these foods have no valuable substances for the organism and vitamins such as C and K.
Given that long-term manned missions are planned with first natural ones Mars and the creation of manned bases and later colonies on the moon and Mars is the presence of fresh food more than necessary for the smooth feeding of people in them.
For this reason, in recent years on the International Space Station, as well as experiments with simulated space environments, efforts have been made to cultivate various plants that are food for humans such as vegetables and fruits.
These efforts are based on revolutionary methods of cultivating artificial light without the need for irrigation. Some of these efforts have been successful as the harvest has been achieved in space. A type of red salad was successfully cultivated in the International Space Station, which even consumed the station crew. A potato on a simulated Martian soil has recently been successfully cultivated.
NASA is working with the Fairchild Tropical Botanical Garden in Miami and several botanists and gardeners on an ambitious program of 1
According to the US Space Agency, so far 106 species of vegetables have been identified that can be cultivated in space. Among them are various types of lettuce and cabbage, and as it became known in the next phase of the experiments, tomatoes are grown.
