The ability to breathe in space is a topic that has been widely discussed in relation to the Dragon Ball franchise, with specific reference to the character Pan. While there is some speculation that Saiyans, who are from a harsher environment, may be able to breathe in space for short periods due to increased lung capacity, it is generally accepted that they cannot, as they need oxygen to survive. This is a challenge that astronauts also face, and they have developed a number of methods to generate oxygen in the vacuum of space, such as using an Environmental Control Unit (ECU) or burning solid lithium perchlorate canisters.

Pan's breathing in space: artistic expression or reality?
Pans breathing in space has been a topic of discussion among fans of the Dragon Ball franchise. While some scenes in the anime and manga suggest that certain characters, like Pan, can breathe in space, others indicate that they cannot. This discrepancy has led to debates among fans, with some offering explanations that reconcile the conflicting evidence.
In the Dragon Ball universe, there are instances where characters like Pan are shown flying or fighting in space without apparent difficulty in breathing. These scenes have sparked discussions on whether Pans, and other characters, possess the ability to breathe in the vacuum of space. However, there are also scenes that contradict this idea, such as Goku using a spacesuit while in space, implying that he is aware of the need for oxygen.
One explanation offered by fans is that the scenes where characters appear to breathe in space are artistic expressions or filler content that may not be canon. It is suggested that these scenes are meant to enhance the storytelling or visual appeal of the anime and manga. For example, the episode involving Vegeta and Nappa going to Arlia is considered filler, and in the manga, they do not deviate from their course. Additionally, it is speculated that some scenes might be set within the planet's atmosphere, where breathing is possible, rather than in the vacuum of space.
Another interpretation considers the biological capabilities of the characters. It is suggested that Saiyans, like Pan, may have increased lung capacity due to their harsh home environment, allowing them to survive temporarily in a variety of atmospheric conditions, including low-pressure zones. This interpretation reconciles the conflicting scenes by suggesting that while Saiyans can breathe in certain space-like conditions, they still require oxygen and cannot survive indefinitely in the vacuum of space.
The debate surrounding Pans breathing in space highlights the interplay between artistic expression and scientific reality in the Dragon Ball franchise. While some fans embrace the suspension of disbelief for artistic purposes, others seek logical explanations that align with the established rules of the Dragon Ball universe. Ultimately, the creators' intentions may remain unclear, leaving room for speculation and interpretation by the fans.

How do astronauts breathe in space?
Astronauts living on the International Space Station (ISS) breathe air that is almost identical to the air we breathe on Earth, with the same pressure and about 80% nitrogen and 20% oxygen. However, creating an environment where astronauts can breathe in space is a complex process.
The ISS has been inhabited by humans since November 2, 2000. The astronauts on board require regular supplies of oxygen, food, and water from Earth. The process of supplying astronauts with oxygen is challenging and risky, as evidenced by a fire that broke out on the Mir space station in 1997 due to the spacecraft's onboard oxygen generator.
To address this challenge, NASA has developed various systems to ensure a continuous supply of oxygen for astronauts. One method involves using electrolysis to split water (H2O) into its basic molecules of hydrogen and oxygen. The oxygen is released into the atmosphere for breathing, while the hydrogen is combined with carbon dioxide exhaled by the crew to produce methane and water through the Sabatier reaction. This process allows for the recycling of resources and reduces the need for resupply missions.
Additionally, backup oxygen systems are in place, such as solid fuel oxygen generator canisters containing lithium perchlorate, similar to those used on commercial jets. Each canister provides enough oxygen for one person for one day. As a further backup, there are also emergency cylinders of bottled compressed oxygen.
Before conducting a spacewalk, astronauts must undergo a "pre-breathe" exercise, breathing pure oxygen inside a pressurized airlock to minimize the chances of getting the bends. This process removes nitrogen from their bodies and prevents the formation of gas bubbles in their blood, which could lead to joint pain, headaches, muscle weakness, numbness, fatigue, and confusion.

Can humans survive in space without a spacesuit?
It is not possible for humans to survive in space without a spacesuit. In space, there is no oxygen to breathe, no pressure to absorb that oxygen into the bloodstream, and no protection from the extreme temperatures. A spacesuit is essential for survival.
Spacecraft like the International Space Station (ISS) are designed for long-term habitation and have various methods for providing astronauts with oxygen. One way is through oxygen generators, which use electricity to electrolyse water, splitting it into hydrogen and oxygen. The oxygen is circulated for the crew to breathe, and the hydrogen is combined with the carbon dioxide they exhale to make methane and water through the Sabatier reaction. The water is reused, and the methane is vented.
Another method is the solid fuel oxygen generator (SFOG), also called oxygen candles or chlorate candles. These canisters contain a mixture of powdered sodium chlorate and iron powder. When ignited, the iron burns at 1112°F (600°C), supplying the heat energy needed for the reaction. This breaks down the sodium chlorate into sodium chloride (table salt) and oxygen gas. Some of the oxygen combines with the iron to form iron oxide.
Additionally, water is reclaimed from the cabin air by removing water vapour exhaled by astronauts, and from their urine through distillation. The reclaimed water is then cleaned and made drinkable.
NASA is also working on improving air quality by developing better methods for sucking carbon dioxide out of the air. They are also aiming to create oxygen and eliminate carbon dioxide naturally by growing plants in future space stations or colonies.

What happens to an unprotected body in space?
Space is a vacuum, with no air, and very, very cold temperatures. The human body is not built for such an environment and cannot last long without protection. The first thing to note is the lack of air. It would take up to 15 seconds to lose consciousness as the body uses up the remaining oxygen in the bloodstream. If you hold your breath, the loss of external pressure would cause the gas inside your lungs to expand, rupturing the lungs and releasing air into the circulatory system. So, the first thing to do if you find yourself in the vacuum of space is to exhale.
After about 10 seconds, the skin and tissue will begin to swell as the water in the body starts to vaporize in the absence of atmospheric pressure. The body will not balloon to the point of exploding, as human skin is strong enough to keep from bursting. However, the water in the body's tissues will expand, and the blood will start to boil. This is a serious problem, as 60% of the human body is made up of water. The body will not freeze immediately, as heat does not leave the body quickly enough due to the lack of convection and conduction.
If you were near a source of heat, your body would mummify, and if not, it would freeze. If you were sealed in a space suit, your body would decompose, but only as long as the oxygen lasted. In either case, the body would remain intact for a very long time without air to facilitate weathering and degradation.
The unprotected body would also be exposed to unfiltered cosmic radiation, resulting in nasty sunburn and decompression sickness.

Can Saiyans breathe in space?
There is much debate on whether Saiyans can breathe in space, with conflicting evidence provided by the Dragon Ball franchise. Some sources claim that Saiyans cannot breathe in space, as they need oxygen to survive. This is supported by scenes in the show where Goku is wearing a spacesuit while in space, implying that he needs a supply of oxygen. Additionally, in the Dragon Ball Super manga, Vegeta states that Saiyans cannot survive in space.
However, there are also scenes in the show that suggest Saiyans can breathe in space. For example, in one scene, Bardock is shown standing with a group of other Saiyans in space, confronting Frieza. This suggests that they are able to breathe in the vacuum of space. Another example is when Nappa and Vegeta stand outside their space pod in space, laughing as they destroy planet Arlia. It is possible that their space pod generates an atmosphere, but it is also speculated that Saiyans, being from a harsher environment, have increased lung capacity and can survive in a variety of atmospheric conditions, including low-pressure zones. This interpretation suggests that Saiyans can breathe in space, but Goku, having been born and raised on Earth, is unaware of this ability and therefore wears a spacesuit.
Goku's ability to survive in space is further explored in Dragon Ball Super, where he fights Beerus in space even outside of his god form. Some fans speculate that Goku is able to survive due to his godly form and absorption of godly ki, which technically makes him a deity. However, it is also suggested that they were still within Earth's atmosphere during this fight.
Overall, there is no clear consensus on whether Saiyans can breathe in space, with different interpretations of the source material leading to conflicting conclusions.
