Food
What kind of food is eaten:
nonperishable foods
some foods can be eaten in their natural form like brownies and fruits.
Condiments such as ketchup, mustard and mayonnaise are provided.
Salt and pepper are available but only in liquid form because if an astronaut is sprinkling then it will float away and can be dangerous because it may end up in an astronaut’s eye.

How astronauts meet the basic need of food in space
How is food cooked?
Foods like fruit can be eaten as is but other foods require adding water, such as macaroni and cheese or spaghetti. Of course, an oven is provided in the space shuttle and the space station to heat foods to the proper temperature.
Foods are also packed ahead of time so that there is enough food for the trip and there is no need of worrying that there won’t be enough.
Where and how is food kept fresh?
There are no refrigerators in space, so
space food must be stored and prepared properly to avoid spillage, espesially on longer missions.
What temperature does water boil/freeze at in space?
In space water can boil at different elevations. For example, water boils at 100*c when 0m off the ground however, at 2400m water may boil at 92*c. Water freezes at about -240*c.
How astronauts meet their basic need of oxygen in space:
How to avoid spillage of water in space?
To avoid spillage of water in space the water is held in bags and you will drink the water using a tube this also keeps the water cold and there is no worry of having to clean up if a spill occurs.

Do astronauts need oxygen tanks in space?
No, astronauts do not need oxygen tanks in space because there is a new spacesuit that astronauts wear and oxygen can be held for a certain amount of time.
