The astronauts on a space mission usually have just the air they take with them (there have been some experiments in storing liquid gases to mix). The carbon dioxide is removed from the air, either by chemicals such as lithium hydroxide, or by using hydrogen that is electrolyzed from fuel cell water to recapture oxygen (Sabatier reaction). Oxygen is added from the fuel cell water and reserve tanks. All of this means that a long-term mission is limited by the supplies of hydrogen and oxygen and water they bring along, or are delivered by resupply.Space vehicles can harness substantial energy from small reactors, fuel cells, and solar panels, but they cannot obtain any air or water in space.
What else can I help you with?
How does the space suit backpack help astronauts in a space environment breathe?
The space suit backpack is called the Portable Life Support System (PLSS) and contains oxygen tanks, a ventilation system, and filters to provide astronauts with breathable air. The PLSS also regulates temperature and removes carbon dioxide from the astronaut's exhaled air, ensuring they have a constant supply of fresh oxygen while in space.
Why do astronauts need an air tank?
Astronauts need an air tank to supply them with oxygen to breathe in the airless environment of space, where there is no atmospheric pressure to support life. The air tank also helps regulate the pressure inside the astronaut's suit and provides a way to expel carbon dioxide.
How do astronauts breathe in rockets?
Astronauts breathe inside rockets using an onboard life support system that supplies them with oxygen while removing carbon dioxide. This system ensures a continuous flow of fresh air for the astronauts during their space journey. They also wear spacesuits that help regulate their temperature and provide additional life support features.
Why does a space shuttle carry its own supply of oxygen?
A space shuttle carries its own supply of oxygen to sustain the astronauts' breathing when they are in space where there is no atmosphere. It ensures they have a continuous source of oxygen for respiration during the mission.
How do astronauts breathe?
Astronauts breathe using the life support systems on their spacecraft or spacesuits. These systems provide a controlled supply of oxygen for them to breathe while in space. Inside the spacecraft, the air is managed to ensure astronauts have a safe and breathable atmosphere.
How do astronauts get supply of fresh air over a long time?
They make their own oxygen by mixing nitrogen with carbon dioxide.
How would you go about storing the extra oxygen and air that would continuously provide fresh air to the astronauts?
To store extra oxygen and air for astronauts, spacecraft utilize tanks or canisters designed to hold compressed gases. Systems are in place to regulate and monitor the flow of oxygen to ensure a continuous supply of fresh air. Additionally, the spacecraft's environmental control system helps to maintain the appropriate oxygen levels within the cabin.
Is it true that each time you breath you get a fresh supply of oxygen?
Yes. Though the air you're breathing might not exactly be 'fresh,' you do get a fresh supply with every inhalation.
What is the definition of air supply?
Air supply refers to the availability or provision of fresh air, typically for breathing or ventilation purposes. It can also refer to the band Air Supply, which is a soft rock group known for their romantic ballads in the 1970s and 1980s.
Is the fresh air come through the AC If any then how many?
Yes, its 1 to 10% of your supply air. ;-)

Why is compressed oxygen used instead of compressed air in space?
Oxygen is the component of air that we consume, so it must be continuously replaced as the astronauts breathe it. The the other components of air, mostly nitrogen, simply come from the initial air supply and do not need to be replaced.

Breath of fresh air or breathe of fresh air?
Its breath of fresh air.
How important is the fresh air intake in maintaining the efficiency of a ventilation system?
Fresh air intake is crucial for maintaining the efficiency of a ventilation system because it helps to remove stale air, odors, and pollutants while providing a constant supply of oxygen for better indoor air quality.
Can astronauts hear each other?
As there is no air , it is difficult , but astronauts use radios.
