Fire needs oxygen in order to burn, and there is no oxygen in space, so rockets must take oxygen with them.
No. Jet engines draw oxygen from the atmosphere to mix and burn with jet fuel, and cannot function in a vacuum. Rockets carry their own oxygen, and can travel in the vacuum of space.
There is no oxygen in space, so spacecraft must carry oxygen with which to burn their fuel and, if they are manned, to allow the crew to breathe.
so the people can breath
I think I know what you're getting at... Rockets burn loads of fuel really quickly so we use jet engines in the atmosphere... The thing is that jet engines need oxygen to mix with fuel to burn it. Rocket engines contain their own oxygen which means that they are the most practical way for us to get into space.
Have you SEEN the price of gasoline lately....Just kidding-- Rockets fuels are rated by Specific Impulse, a measure of how fast the explosion travels when it shoots out the back. Gasoline is good as a fuel, but not as good as many others. The space shuttle uses hydrogen and oxygen.
Jets use jet engines which obtain the oxygen they need to operate from the air. There is no air in space, hence no oxygen, meaning that they cannot fly in space. Once they get to a certain altitude, there is not enough power to fly higher. Rockets carry their own oxygen supply, normally in the form of Liquid Oxygen, to allow their engines to work.
Rockets need oxygen to facilitate the chemical reaction for generating thrust. By combining oxygen with fuel in the combustion chamber, rockets produce the hot gases needed to propel the vehicle through space. This enables rockets to overcome the lack of atmospheric oxygen present in space.
Rockets carry their own fuel and oxygen for propulsion, allowing them to operate in space where there is no atmosphere. Airplanes rely on engines that require oxygen from the atmosphere to generate thrust and lift. Rockets go to space, while airplanes fly within Earth's atmosphere.
The amount of fuel a spaceship and its rockets can hold varies depending on the size and purpose of the spacecraft. For example, the Space Shuttle used to carry over 1.6 million pounds of propellant for its main engines. Rockets like the Falcon 9 can carry hundreds of thousands of pounds of fuel for their engines.
So that the astronauts on board can breath, of course. :)
Rockets carry oxygen into space as part of their propellant mixture to enable combustion with the rocket's fuel. This reaction generates the necessary thrust to propel the rocket forward. Oxygen is crucial for combustion to occur in the rocket engine, allowing the propulsion system to function effectively in the vacuum of space.
Many rockets that go into space do carry humans, but, most rockets do not.
