No, there is no regular pizza in space currently, although there have been some experiments to make it happen. Scientists at the University of Sydney recently completed a research project in which they attempted to create pizza that would be suitable and safe for astronauts to consume in space.
The project used wheat developed specifically for space, paired with processed toppings, such as tomato powder, modified cheese, and yeast-based pizza dough. The experiment was a success, and the team believes that their research could pave the way to creating an actual “space pizza” that could be enjoyed by astronauts beyond Earth.
The team is now working on refining the recipe and making it shelf-stable so that it can be eaten in space.

What foods are not allowed in space?
The foods that are strictly not allowed in space are anything with a strong odor, since the recycled air inside the spacecraft could make it unpleasant for astronauts. Highly crumbly foods should also be avoided, since even small crumbs can float in zero gravity, potentially clogging filters and circuitry.
Similarly, sticky foods should be avoided since they can be difficult to clean up. Furthermore, food with sharp edges should be avoided, as they could cut fingers or end up floating freely, posing a choking hazard.
Additionally, all food items should be either completely cooked or dehydrated, as uncooked food can spoil, adding too much risk and complexity to the food storage process. Finally, foods that are high in salt or sugar should be avoided, since many astronauts already experience fluid loss, which can be exacerbated by a high-salt or sugary diet.
Can I nut in space?
No, you cannot nut in space. Space is an inhospitable environment for any form of life, including nut trees. And the temperatures and radiation levels are too extreme for nuts to survive. Additionally, because of the weightlessness of space, nuts or anything else floating in the environment can interfere with the operation or maintenance of a spacecraft.
For these reasons, no nuts or any other plants or animals can survive in space.
What kind of food does astronauts eat in space?
Astronauts in space typically eat a variety of foods, depending on the mission. The most common food sources are selected from a variety of rehydratable, freeze-dried, thermostabilized and natural foods.
Rehydrated and thermostabilized foods come in lightweight packages and can be consumed without any additional preparation. Freeze-dried and natural type do not require any form of reconstitution, and are therefore ideal for astronauts on longer missions.
They generally consist of a variety of fruits, vegetables, grains, nuts, and seeds. Some of the natural foods can also be easily prepared, like oatmeal and instant soups.
Aside from the different types of food sources, astronauts also have the option of picking up condiments and spices to enhance the flavor of their meals. Some common condiments astronauts use include hot sauce, Italian dressing, and Tabasco sauce.
In addition to the food sources, astronauts also have access to fluids like water and juice. The International Space Station also includes a special machine that can turn waste water into drinkable water.
However, they are typically limited to a one-liter daily maximum consumption.
If you’re interested in what astronauts eat in space, you can usually find menus posted on NASA websites. This is a great way to get a sense for the types of meals that astronauts consume during their mission.
Why is eating in space not easy?
Eating in space is not easy for a variety of reasons. Physically, the lack of gravity means that food and liquids float around, making it hard to keep them contained. Surfaces like tables, chairs or walls are essential for containing food, but these are only available in certain areas of a spacecraft, such as the crew quarters.
Furthermore, astronauts need to eat three or four meals a day, but the lack of a sense of direction in space makes it difficult to find the food. As such, having a routine is essential to remembering where the food is stored and to eat enough regularly.
Additionally, the lack of gravity means that food that may taste good on Earth may not taste as good in space. This is because the human taste bud sensitivity is lower in space due to the absence of gravity and the lower breathing rate of astronauts.
To try and combat this, research is underway to make food that is more palatable in space, such as thermostabilized foods, which have a longer shelf-life, with reduced moisture that prevents bacteria from growing in the food.
Overall, the unique physical conditions in space make eating a challenging process. However, with the right equipment, routine and food, astronauts can stay healthy and continue to explore space.
What can astronauts not eat?
Astronauts generally don’t eat a typical diet that includes fresh foods. They must rely on special types of pre-packaged food for their nutritional needs. This food is preserved using various methods to ensure that the food is safe from bacteria, mold, and other organisms that may cause food poisoning.
These forms of preservation also allow the food to be stored for long periods of time without spoiling. Some of the types of food that astronauts cannot eat include fresh fruits and vegetables, raw eggs, raw fish, processed meats, and non-sterile water.
In addition, some foods may not be compatible with the microgravity environment of space, which can make them difficult to eat in the confines of a spacecraft. Astronauts must carry pre-packaged meals and snacks that are often freeze-dried, rehydratable, or thermostabilized so they can be safely consumed in outer space.
