At 9:22 am on June 17, the Shenzhou 12 manned spacecraft was successfully ignited and launched. This is also the 19th mission since the establishment of my country’s manned space project. This time Three Chinese astronauts will stay in the Tianhe core module for the first time, embark on a three-month "space journey", and will also conduct two exit activities. According to Chinese media, our country’s space station is equipped with one bathroom and three separate bedrooms to ensure that astronauts can live comfortably in space. Now that the living problem has been solved, some people may think that astronauts have to live in space for nine days. What will happen to their food source for ten days? Will it be the same as what we eat on earth?

In fact, astronauts eat the same food in space as we do on earth. Before our country's three astronauts set off, many nutritionists specially prepared more than 120 kinds of rich space food, which were nutritionally balanced and rich in variety. The dining area was also equipped with food heating, refrigeration and drinking water functions. Now it can be said that Chinese cuisine has gone out of the world and completely out of the earth. Many people may have the impression that most space food is compressed biscuits and cans. In fact, the food for Chinese astronauts is far more than these. It also includes a variety of sweet and delicious meals, such as fish-flavored shredded pork. , braised pork, lotus seed porridge, etc.

So from a nutritional point of view, space food must meet the nutritional needs of astronauts under weightless conditions. There are several points that require special attention. First of all, during space flight, because The reason for weightlessness is that astronauts lose more calcium in their bodies, which will lead to muscle atrophy. Therefore, at this time, they need to take in a lot of nutrients from food to ensure that the astronauts' bodies can supplement enough protein and calcium.

Nowadays, among the world’s aerospace foods, the meals of Chinese astronauts can be said to be the most distinctive. Compared with Western burgers and French fries, our country’s traditional Chinese cuisine will appear in aerospace recipes. At the time of Shenzhou 5, my country's eight-treasure rice, soy sauce beef, Kung Pao chicken, etc. had all been sent to outer space. Now the three astronauts carried by my country's Shenzhou XII will live in space for a long 90 days. This time they brought more than 120 kinds of space food, which are all formulated according to the preferences of different astronauts. When astronauts first enter space, their bodies are completely weightless and they easily feel fatigued, so their appetite will also decrease. At this time, astronauts will choose to eat relatively simple and light foods to maintain their health. energy required. When astronauts adapt to the space environment, they will officially enter the state of eating three meals a day.

From Shenzhou 5 to today’s Shenzhou 12, our country’s scientific researchers have put in countless efforts, which is also the best testimony of our country’s aerospace industry. At that time, when our country's first artificial satellite was launched into space, it opened the door for our country to rush into the outer sky. Now, after several generations of unremitting efforts, we have now become a space power. I believe that with the development of our country's aerospace industry, our astronauts will have more types of food.
