Have You Ever Wondered…
- What do astronauts eat in space?
- How are freeze-dried foods made?
- How did the space shuttle Endeavour get its name?
Eating in space presents some remarkable difficulties for space explorers. Why? There’s no gravity! In the event that you let go of a bit of food, it will coast off and float around your space vehicle.
Shouldn’t something be said about some water? Disregard it! Water won’t remain in a cup. It, as well, will glide out and linger palpably.
To permit space travelers to remain in space for quite a long time or weeks one after another, researchers needed to imagine unique methods of bundling and eating nourishments in space. The primary such space nourishments were delicate food sources (sort of like infant food!) bundled in tubes like toothpaste.
For instance, John Glenn turned into the first U.S. space explorer to eat in space when he ate fruit purée from an aluminum tube during a 1962 Mercury space mission. He needed to press the food into his mouth.
In the event that that doesn’t sound tantalizing to you, you’re in good company. Space explorers weren’t wild about it either. Inevitably, researchers grew better, more delicious nourishments that were simpler to eat.
For instance, freeze-drying was a method that was created. Food was prepared, immediately solidified, and afterward got dried out in a unique vacuum chamber. Freeze-dried food didn’t should be refrigerated and would keep going quite a while.
To make most freeze-dried nourishments, space explorers press water into the food bundles and afterward eat the food after it ingests the water. Space explorers can utilize heated water to make hot dinners that are scrumptious and nutritious.
Some freeze-dried nourishments, similar to natural product, can be eaten dry. Actually, you may eat space traveler food occasionally without acknowledging it. Today, many breakfast grains incorporate freeze-dried natural products, similar to strawberries, that are scrumptious and include shading and flavor.
Astronauts flying modern space shuttle missions now eat many of the same foods they eat on Earth. Food still needs to be dehydrated or prepared in special ways, but space shuttles now have full kitchens with hot water and an oven.
Astronauts can also use condiments, like ketchup, mustard, and mayonnaise, in packets to add flavor. Salt and pepper can be used, too, but they have to be used in a liquid form because otherwise the grains would just float away!
Drinks are also dehydrated and kept in powder form in special pouches. The pouches have built-in straws or special nozzles that let astronauts drink straight from the pouch since gravity makes drinking from a cup a messy idea.
To make sure their food doesn’t float off, astronauts attach their food containers and utensils to special trays with Velcro fasteners. The trays also fasten to their laps, so they can enjoy a meal while sitting down.
Nutritionists plan astronaut meals to make sure they get all of the nutrients and vitamins they need to perform their important work in space. Some astronauts begin to experience digestive problems after they’ve been in space a long time.
Experts believe these problems may be caused by a decrease in the number of “good” bacteria in astronauts’ bodies. A group of high school students in Jefferson County, Kentucky, is going to help researchers learn more about this issue when the students’ experiment flies into outer space on the space shuttle Endeavour.
As part of the Student Spaceflight Experiments Program, the students designed an experiment to test the effect of microgravity on Lactobacillus GG, which is a probiotic that could help future astronauts stay healthier in space.
Altogether, there are 16 tests on Endeavor that were planned by understudies. This is just proper since Endeavor is the main space transport named by youngsters. Rudimentary and auxiliary understudies contended in a public transport naming rivalry in 1988.
The triumphant name — Endeavor — depended on an eighteenth century British investigating vessel. The name has created a touch of turmoil on occasion, however. Numerous individuals need to spell it “Try” since that is the American spelling of the word. The space transport, notwithstanding, utilizes the British spelling with a “u” since that is the way its namesake was spelled.
