Space immigrant food

On February 9, 65438, CNN reported that NASA flight engineers had successfully harvested 20 radishes planted in the advanced plant culture environment of the International Space Station. It is said that these hard-won 20 radishes will be specially treated, refrigerated and sent back to Earth next year.

From a data released by NASA, we know that radish is planted in zero gravity environment, and it is very rare to harvest fruits in such an environment. According to this explanation, we also know that the crew planted many crops on the International Space Station, including 15 plants and 8 green leaves. The staff of NASA also explained why many crops should be planted. Planting a variety of crops helps scientists analyze which plants can grow and bear fruit in zero gravity. This kind of experiment is very helpful and scientific.

In the space station, astronauts who perform long-term tasks can also slightly alleviate the problem of insufficient vegetables and food by planting these space radishes, thus helping the astronauts of the International Space Station achieve a balanced nutrition. The planting method of radish is very simple. Scientists are already familiar with the characteristics of this crop, so it only takes 27 days to ripen and bear fruit.

Although the taste, taste and nutrition of radish planted in space will not be better than those planted on the ground, the food problem of astronauts who perform long-term tasks can be solved after such technology matures. From a larger perspective, this slowly mature space planting technology is also the maturity of space technology. In 20 14, scientists have begun to build structures with the same temperature, humidity and carbon dioxide concentration as the earth's surface? Surface-like environment? If you want to use this environment to grow vegetables in space, if the technology is mature, it can also be a technology that benefits mankind. Photosynthesis is the basis of plant survival. If we can make a breakthrough in technology, we can save the area of planting land on the ground. It can indeed be a project for the benefit of mankind.
