Space Food
When astronauts leave for a mission, they’ll be unable to cool their food, so anything they take along must be nonperishable. The space food that they bring must also be straightforward to eat without making a mess, since the astronauts will be outside of the gravitational field, and any crumbs from their food could float around and get stuck in gear or in the astronauts ‘ eyes.
Because astronauts will most likely be in space for weeks or months at a time, they’re sometimes unable to bring fresh food ,eg fruit and plants, on board the shuttle.
Many varieties of space food are dehydrated, or freeze-dried, and sealed. When the astronaut is prepared to eat the space food, he will add water to rehydrate the meal so it will be eatable. Though there’s no fridge on a shuttle, there’s a range, so astronauts will be in a position to heat up or bake their space food as required. While in space, astronauts sometimes use flour tortillas for sandwiches, rather than bread. This is as bread can have lots of crumbs, which may float around in the shuttle. For seasonings to go on space food, ketchup, mustard, and mayo are supplied in their standard forms, but pepper and salt are supplied only in the form of a liquid, as the crushed version would be certain to float away. Today, a multitude of menu options are available for astronauts as space food. They can select from meals including meat stroganoff, chicken teriyaki, and turkey tetrazzini.
Generally , an astronaut will have the opportunity to decide his very own space food meals from a menu list far ahead of the shuttle launch.
