SOLAR SYSTEM

Detailed explanation-1: -Foods are either partially or completely dehydrated to prevent them from spoiling. Meats are exposed to radiation before they are put onboard the shuttle to give them a longer shelf life. Astronauts eat three meals a day (plus periodic snacks), just as they do on Earth.

Detailed explanation-2: -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-3: -Space food commonly comes in plastic packaging or cans. To prevent their food from floating away at meal time, packaging has Velcro patches so it can be attached to a tray or table. Tape, tethers, and magnets are also used to affix food items to surfaces.

Detailed explanation-4: -Astronauts involuntarily lose body water during space missions. Body fluid that is usually pulled towards the feet by Earth’s gravity shifts rapidly during spaceflight, moving from the legs into the upper body. This fluid shift increases pressure in the head and torso, and body water loss soon follows.

Detailed explanation-5: -In reduced gravity, these fluids move freely in our bodies, creating a similar feeling to a head cold or blocked sinuses and leaving many foods tasting bland. To reactivate their taste buds, many astronauts to have a preference for piquant and hot foods such as peppers and spicy flavours such as horseradish or wasabi.
