We must remember that the cosmic home is in Earth's orbit, about 400 kilometers above our heads. There are microgravity conditions there, so chemical reactions often take place in a completely different way than on the Earth's surface. Growing vegetables or fruit that can be used as part of the diet of the inhabitants of the International Space Station is not a simple task.
If we are serious about becoming an interplanetary civilization and the colonization of the Moon and Mars, then we need to develop technologies that will allow us to easily produce fresh food for the normal functioning of astronauts. For several years, experiments with space gardens have been carried out on board the space house. First, lettuce was successfully grown there, and now radish.
The American astronaut Kate Rubins, who has been in a space home since October this year, is involved in the Plant Habitat-02 project. On a daily basis, she deals with a space garden there and experiments related to DNA sequencing, the development of mRNA vaccines and genetic Planet Watching few days ago Rubins boasted about the fruits, and in fact vegetables, of her hard work. The astronaut grew as many as 20 radishes. All of them have already been packed and frozen in special mobile cold stores. In April next year, they will return with her to Earth and will be sent to NASA laboratories, where they will be subjected to further tests. Scientists will check their taste, smell and nutritional value, and compare them with a control group that was bred on Earth. Then we should find out if there are any significant differences between them.
Interestingly, two years ago, similar experiments with the cultivation of vegetables were carried out by the Chinese on board their Chang'e-4 lander, which appeared on the surface of the moon invisible from Earth. Scientists reported success in breeding oilseed rape, cotton, radish and potatoes. In the laboratory and mini-garden of the lunar biosphere, that is, in fact, a special container, there were silkworms and fruit flies. Their task was to feed on e.g. yeast and the emission of carbon dioxide that was taken up by plants.
