No one in the universe sends pizza. How sad this fact is. If you want to become an astronaut when you grow up, don't have any fantasies about space meals. For astronauts, eating in the universe is a challenge. Why? Because of weight loss. If you let go of the same food, it will float in the universe as well as the spacecraft surrounding you.
What happens if a glass of water? Forget it! The water won't be in the cup. It will also only float and hang in mid-air. In order for astronauts to stay in the universe for days or weeks, scientists must invent a special way to pack and eat food in the universe. The first such food is light food (similar to baby food), packaged in a hose like toothpaste.
For example, in the 1962 Mercury space mission, John Glenn was the first American astronaut to eat in the universe. He ate apple pie from aluminum tubes. He had to squeeze the food to put it in his mouth. If this sounds disgusting to you, believe you are not the only one. Astronauts don't like it either. Eventually, the scientists made improvements, and the food was tastier and easier to eat.
For example, the freezing and dehydration technology has been developed. After cooking, the food is quickly frozen and then put into the vacuum chamber to dehydrate. Freeze and dehydrated foods do not need to be thawed and can be stored for a long time. In order not to waste frozen dehydrated food, the astronaut squeezes water on the food packaging. When the food packaging absorbs moisture fully, the astronauts start meals. Astronauts can heat food with hot water to make it more delicious and nutritious.
Some frozen and dehydrated foods, such as fruits, can be eaten dry. In fact, you may eat astronauts’ food from time to time without knowing it. Today, many breakfast cereals including frozen dehydrated fruits, such as strawberries, are delicious and have added colors and spices.
Astronauts performing modern spacecraft missions now eat much of the food they eat on Earth. Food still needs to be dehydrated or treated in special ways, but there is already a complete set of kitchenware in the spacecraft, including hot water and electric stoves. Astronauts can also use seasonings such as bags of tomato paste, butter and mayonnaise . Salt and chili sauce can also be used, but they must be made into liquid form as the granular form may float away.
Beverage is also a powder made into bags of powder. Those bags have built-in straws or special nozzles that are convenient for astronauts to drink directly from the bag because gravity is a hassle to drink with a cup. To ensure that their food does not float away, the astronauts secured their food containers and utensils to special trays with velcro. Those trays are also fixed to their thighs so they can sit down and enjoy the food.
Nutrition experts pair meals for astronauts to ensure they consume enough nutrients and vitamins to perform their important tasks in the universe. Some astronauts will have digestive problems after staying in the universe for a long time. Experts believe these problems are caused by the decrease in good cells in astronauts. A group of high school students in KentuckyJefferson County plan to assist researchers in researching this issue. Those students experience the feeling of flying into outer space on the "Term" spacecraft.
As part of the Student Space Flight Experience Program, students designed an experiment to test the effects of microgravity on Lactobacillus GG, a probiotic that can help future astronauts stay healthy in space. A total of 16 experiments on the "Effort" were designed by students. This is more appropriate because the Ultimate is the only spacecraft named by children. The 1988 National Spaceship Naming Competition participated by junior and high school students. The winning name of
- "Effort" - is named after the 18th-century British probe ship. This naming has caused confusion many times. Many people want to spell it "Endeavor" because it is American spelling. But the spacecraft uses the British spelling with 'u' because that's the spelling of the detection ship's name.
