if outer space is mostly hydrogen then would oxygen be the only ingredient needed to maintain a combustion type of propulsion?
Astronomers have used NASA's Chandra X-ray Observatory to find evidence our Milky Way Galaxy is embedded in an enormous halo of hot gas that extends for hundreds of thousands of light years. The estimated mass of the halo is comparable to the mass of all the stars in the galaxy.
That's a lot of gas over a wide area to begin working with.The estimated mass depends on factors such as the amount of oxygen relative to hydrogen, which is the dominant element in the gas.

Not sure what you mean there...but I did not know how much of a vacuum it was to make it unusable.
Well, if 70% of the medium in the area was hydrogen it could be as high as 700,000 parts per million. But that could be spread over a huge amount of space - maybe you were thinking that space itself was contributing to the ppm measurement.how many ppm is it? or am I just misinformed

tonybaloney41 said:lets say at 1000 miles away from Earth how many psi of a vacuum are we talking? and is the vacuum differ in different parts of outerspace to let's say 1000 miles away from Mars to keep it apples to apples

tonybaloney41 said:sorry but school project is why I ask so much, so are you saying that the vacuum in space is diffrent than if we removed the air from a container to negative pressure and measured it in psi? or is it only a vacuum of molecules and we just don't know how to explain the absence of them?
Oxygen is a crucial element in combustion propulsion in outer space. It serves as the oxidizer, which combines with the fuel to produce energy in the form of heat and thrust. Without oxygen, combustion cannot occur, and thus propulsion would not be possible.
In outer space, oxygen can be obtained through various methods. One way is through the use of oxygen tanks brought from Earth. Another method is through electrolysis, where water molecules are broken down into oxygen and hydrogen. Oxygen can also be extracted from the carbon dioxide in the spacecraft's atmosphere using a process called Sabatier reaction.
No, combustion propulsion cannot occur without oxygen in outer space. Other fuels, such as liquid hydrogen, can be used in place of oxygen, but an oxidizer is still required for combustion to take place. Without an oxidizer, there is no source of oxygen to combine with the fuel and generate thrust.
Yes, the amount of oxygen needed for combustion propulsion is different in outer space compared to on Earth. In space, the concentration of oxygen is lower than on Earth, making it necessary to bring or produce more oxygen for combustion to occur. Additionally, the lack of atmospheric pressure in space also affects the amount of oxygen required for combustion.
Yes, there are potential risks associated with using oxygen for combustion propulsion in outer space. Oxygen is highly flammable and can pose a fire hazard if not handled carefully. The presence of oxygen can also increase the risk of explosions in the spacecraft. Therefore, strict safety protocols and precautions must be followed when using oxygen for propulsion in outer space.
