SOLAR SYSTEM

Detailed explanation-1: -The astronauts will use a special tray on the ISS to hold their food during preparation and eating. Because every-thing drifts in a microgravity environment, utensils and food containers need to be held in place. Food trays will be designed on the basis of the food packages that will be used on the ISS.

Detailed explanation-2: -Food for NASA’s current astronauts is prepared and packaged at the Space Food Systems Laboratory at Johnson Space Center in Houston, Texas. There, astronauts select the meals they would like for their mission.

Detailed explanation-3: -On board the space shuttle, dehydrated foods and drinks make up much of the menu. The major reason for using dehydrated foods and drinks is that water, a byproduct of the shuttle’s fuel cells, is abundantly available for food preparation. Using rehydratable food and drinks significantly reduces weight.

Detailed explanation-4: -Dehydrated and Freeze-Dried Food in Space To do so, they injected water into a dried food package using a specially designed water gun. Once the water was injected, their food was ready for consumption within minutes.

Detailed explanation-5: -When mealtime rolls around, astronauts go into the galley area in the shuttle’s middeck. There they add water to freeze-dried foods and dehydrated drinks from a rehydration station that dispenses both hot and cold water. They heat foods in a forced-air convection oven that’s kept between 160 and 170 degrees Fahrenheit.

Detailed explanation-6: -For astronauts to rehydrate themselves effectively, they must take in both water and electrolytes-or salts. Both the quality and quantity of electrolytes critically affect how water is absorbed and distributed within the body.

Detailed explanation-7: -To survive there, astronauts must wear an extravehicular mobility unit (EMU)-commonly called a spacesuit. An astronaut’s spacesuit contains many different parts. Each part plays a crucial role in the astronaut’s survival, and all the parts must fit together perfectly.
