How to contain an atmosphere in space?

In summary, the conversation revolved around the idea of containing an atmosphere in space without gravity, using a plasma magnetic field. It was suggested that it could be possible to put a charge on the air and contain it electromagnetically, but there could be practical limitations. The concept of placing plants and animals in these spheres was also discussed, but it was deemed not a practical solution. The group also mentioned the disruptive effects of a craft entering or leaving the field, as well as the challenges of dealing with the solar wind. It was suggested that if the technology could handle the solar wind, it could potentially also handle traversing spacecraft.

Ok this is an interesting idea I had today. Would it be possible and how to contain an atmosphere in space without gravity. Like some sort of plasma magnetic field. Not sure there is a real practical use for Themis other then studying asteroids without space suits.

You could put a charge on the air and contain it electromagnetically - yes. That would be fun right!

So if there was a spaceship going in and out of the field would there be a disruption in the field? I imagine some air would get out on leaving.

Imagine placing plants and animals in these spheres. There could be lots of fun and interesting things.

Its not a practical solution... look up "magnetic bottle".
A craft going in and out would be hugely disruptive... perhaps have it enter or leave through the coils.
Plants woiud probably not grow well, and a field big enough to enclose an asteroid could be dangerous to health... the air would constantly smell of ozone and recombining molecules would become neutral and escape. The remaining charged air would never be still.

not to mention the very disruptive Solar Wind traveling at speeds of anything between 300 - 2000 km/sec
That wind is going to have a strong dispersive effectDave

Good point: if the tech can cope with the solar wind than it can probably cope with traversing spacecraft .
 

1. How do you create an atmosphere in space?

Creating an atmosphere in space requires a combination of factors. First, you need a source of gas or gas-forming substances, such as water or carbon dioxide. Second, you need a containment system, such as a pressurized vessel or a magnetic field. Third, you need a way to regulate the temperature and composition of the atmosphere to sustain life.

2. What are the challenges of containing an atmosphere in space?

The main challenge of containing an atmosphere in space is the lack of gravity. Without gravity, the gas molecules will quickly disperse and escape into the vacuum of space. Therefore, a strong containment system and a method of regulating the atmosphere's pressure and composition are crucial.

3. Can we use Earth's atmosphere as a model for containing an atmosphere in space?

While Earth's atmosphere can provide some insights into containing an atmosphere in space, it is not a perfect model. The conditions in space, such as lack of gravity and extreme temperatures, require different approaches to creating and maintaining an atmosphere.

4. What are some possible methods for containing an atmosphere in space?

Some possible methods for containing an atmosphere in space include using pressurized vessels, creating a magnetic field, or building a sealed habitat. Each method has its own advantages and challenges, and further research is needed to determine the most effective approach.

5. How can we ensure the sustainability of the contained atmosphere in space?

To ensure the sustainability of a contained atmosphere in space, it is crucial to continuously monitor and regulate its pressure, temperature, and composition. This can be achieved through advanced technologies and systems that can detect and adjust any changes in the atmosphere. Additionally, finding a renewable source of gas or gas-forming substances is essential for long-term sustainability.
