When we watch the news or a documentary about the NASA astronauts afterburner and a Russian expedition to the space shuttle. And residents of the International Space Station, which orbits in Earth orbit. You who read me wonder how astronauts will live on, however. Especially eating it is so difficult in microgravity Background.
From John Glenn, the first U.S. astronaut. Traveling with space missions to date, these rocket astronauts on the International Space Station today. And nutrition research for the space program evolved to the point where astronauts have food that tastes delicious. Packaging that is easy to eat.
To understand the process of food preparation space. We need to think back to a bygone era explorers faced problems. As long trip by land and sea. Whether it's food trucks are adequate for the demand. Food must always be ready to be eaten throughout the trip. And nutrients that are useful and adequate for the needs of the body. To avoid vitamin deficiency diseases such as scurvy. (Scurvy) caused by vitamin C deficiency.
In early historic times Discover techniques to preserving humanity by making it dry and stored in a cool, dry container. Food Dehydrator Made by butchering fish and some fruit into thin sheets and then dry in the sun. Also, it has been preserved by coating it with salt or pickled by immersion in salt water, etc..
Preservation techniques developed afterburner later to store food in sealed containers. The pasteurized (Thermal microorganisms can not survive) and packed into cans. Thus, at present there are many foods that can be stored for a long time. Latest technology afterburner to preserve the sudden, chilling and freezing. (Quick-freezing), which makes it possible to maintain the flavor and nutrients in them.
Form of preservation and food packaging, as mentioned above, this is a good and effective for our people on the ground, but still not adequate for use in space. There are some limitations to consider in the process of shipping is the weight and volume. Moreover, the bigger obstacle is microgravity. (If correctly Be called low-gravity afterburner conditions) must be in the food preparation afterburner process. afterburner Packaging afterburner Design And storage When used in Project Mercury astronauts and 1962 are both packaged in tubes and chunky pieces. Wrapped in plastic afterburner (image from NASA) Project Mercury.
Project Mercury was the flight test program in the early days of the space program. The fly each time period. Probably only a few minutes up to a maximum of one day. Mission short, this is not required to prepare food for every meal, however, the pilots in Project Mercury has become a guinea pig in testing afterburner the physiology of eating human in an environment with gravity so low, chewing, drinking, afterburner swallowing food whole. regular food and liquid
Food for astronauts in the early days. A semi-dry And semi-liquid food packed in aluminum tubes resembling a tube of toothpaste. Tube with putty material. Prevent the formation of hydrogen gas, which is a reaction between the metal surface afterburner with acidic foods such as apple juice aluminum tubes used in early tend to weigh more than the food contained within. Later, with the development of a lightweight plastic tube. So to the astronauts with food is a little cloying. Because most appetizing taste. And cumbersome to add water to the dry food cooked.
At the end of the project Began to be produced and tested food drying and pelletizing. It is a rectangular piece bite. Do not cut the bite or eat. Food becomes soft by chewing in the mouth. (Not to be mixed with water before eating) more than that. Food before being coated with gelatin to make them fall apart. Prevent the piece of food slipping away. This could be a blockage in the devices on vehicles or even harmful afterburner if accidentally inhaled through the nose with the pilot into the lungs. The container afterburner is plastic films by vacuum encapsulation. In addition to food packaging also helps prevent moisture. Treatment of smell and taste Including preservation for longer. Project Gemini Instant afterburner food packing bag used in the Apollo program. Before afterburner eating to fill hot water into the pipe at the bottom of the bag. Eating by spoon In the meat mix with vegetables (image from NASA).
Space food has evolved to form the Gemini project. In terms of a variety of food and packaging. The process of removing water from food. Space food is made in a similar food. Both color and taste like grape juice, orange juice, apple juice, toast, chocolate, rice, chicken soup, beef stew, turkey and gravy, etc..
Food dehydrator is a natural process that can occur for people in tropical countries. But in countries with cold climate requires a process called. Freeze drying (freeze drying) technique has been used in the space program. Beginning of the filleting food into thin slices. Cut into small cubes Or dissolved into the liquid To shorten the time to cook. The cooked food is frozen quickly. Food that is placed on a tray and then put in a vacuum chamber with air pressure lowered down. With increasing temperature with a heating pad.
Under low pressure and high temperature. Ice crystals in frozen food before it evaporates into steam. The steam will be back on the ice again.
