There was a time when traveling to space seemed impossible. But now, hundreds of people have left Earth’s atmosphere and wandered into outer space. Although there is still much to explore, thanks to researchers and astronauts some cosmic mysteries have been uncovered.
For example, we know that one of the many differences between Earth and outer space is the amount of gravity. According POT, there is only a small amount of gravity in space, unlike on Earth where the force constantly pulls us downward and allows our feet to remain planted on the ground. However, the low gravity in space makes both people and objects more likely to float.
The more we learn about gravity in space, the more we know which objects don’t belong in space. Thanks to low gravity in outer space, these items have been removed from the space travel eligibility list and some may surprise you.
1. Are chairs allowed in the space?

Furniture in space is a little different than what is here on Earth. Common items, such as chairs, are useless when gravity is low. With minimal gravity, it’s difficult to sit in a chair, let alone keep a chair stationary without it being bolted to the floor.
In fact, the International Space Station, a large spacecraft that serves as the home and scientific laboratory where astronauts reside, has nowhere to sit on the floor. Since traditional furniture such as chairs would basically float in space, they are considered more of a hazard than a comfort.

Where do astronauts sit when they eat?
While traditional chairs may not be found aboard the International Space Station, astronauts are still required to eat at least three meals a day. So where do they sit while eating these meals?
It turns out that the astronauts are simply trying stabilize while they float while they eat. It helps that your meals have specific restrictions and are pre-packaged or canned, allowing for minimal mess. There’s also present food trays They connect to a wall or the astronaut’s lap via fabric fasteners designed to keep food in place.
2. Are pens and pencils allowed in the space?

In the 1960s, during the height of space exploration, NASA scientists quickly discovered that it was almost impossible to use ink or pens in space. Astronauts would have difficulty using pens due to the lack of gravity, which prevented ink from the cartridge from reaching the tip and transferring it to the paper.
On the other hand, pencils were also prohibited as Broken graphite could cause a danger to the crew, or float and become trapped in crucial electronic components. Not to mention that the flammable wood of the pencil posed a danger in itself.
What do astronauts use to write in space?
Astronauts surely have a lot to report while they are in space. This is exactly why a special space pen was created called the Fisher Space Pen, an anti-gravity pen created by Paul Fisher and launched into space every NASA spacecraft with crew on board since 1968. The pen uses a nitrogen-pressurized ink cartridge allowing it to be used even in zero gravity conditions.
3. Can you eat bread in space?

Crumbs and space are not the best mixes. While bread can be considered a staple food and a great source of carbohydrates, its crumbly and messy nature makes it unsuitable for the space station. Cleanliness is of utmost importance and crumbs can easily fly away in low gravity. This, combined with the short shelf life of bread, makes it another item that is not allowed in space.

What do astronauts eat in space?
Don’t worry, astronauts can still eat peanut butter and jelly sandwiches. They will simply have to use tortillas instead of bread. Another option is to use pita bread or flatbread, basically anything that minimizes crumbs.
4. Can you drink carbonated drinks in space?

If you can’t do without soft drinks, then the space is probably not for you. In fact, not all carbonated drinks are allowed in space because their properties change, which causes problems for astronauts.
Due to microgravity, the dissolved carbon dioxide In these drinks it does not separate and rise to the surface as it does on Earth. If consumed at minimal gravity, carbonation throughout the drink can cause discomfort to astronauts and produce symptoms similar to acid reflux. Plus, with microgravity, these drinks would probably also float around in space and cause a bigger mess, not to mention the additional pollution the drink cans would add to the spacecraft.
What do astronauts drink in space?
tThe best option astronauts have to prevent dehydration is water. Whole milk and alcohol are not suitable for space because they do not dissolve properly and contain ingredients that can damage equipment. However, freeze-dried drink mixes are other options as they can be added to water.
5. Is salt and pepper allowed in the space?

In microgravity space, condiments are a danger because they can be quite messy, which is why space travel has been banned. Condiments can easily crumble into pieces that can clog air purifiers and filters and even damage equipment.

This means that pPopular seasonings like salt and pepper are not available in their traditional form. however small individual packets of liquid salt and pepper It can be used by astronauts in space.
6. Can astronauts eat ice cream in space?

Unfortunately, one of Earth’s most popular desserts is not allowed in space in its traditional form. The messy nature of ice cream makes it impractical to enjoy it while floating in space. Furthermore, ice cream has a given shelf life of approximately six weeks remain fresh in the freezer once opened, a requirement that the strict conditions aboard the spacecraft cannot meet.
What is astronaut ice cream?
There’s astronaut ice cream, which is essentially freeze-dried ice cream that doesn’t require a refrigerator and doesn’t melt. In fact, he did an initial appearance in space during the Apollo 7 mission in 1968. However, it was not a hit among astronauts due to its lack of flavor and crumbly composition. Ironically, astronaut ice cream became popular on earthespecially in science museums and gift shops around the world.
