In space there is no oxygen. Space is a vacuum. All things like a rocket going to space, require a fuel to burn, oxygen and a heater. Since there is no oxygen is space they need to provide it for them. Meaning the reaction can take place correctly.
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 need to carry their own supply of oxygen because they travel through the vacuum of space where there is no atmosphere to provide oxygen for combustion. By carrying their own oxidizer, such as liquid oxygen, rockets can generate the thrust needed to propel themselves forward.
Fire needs oxygen in order to burn, and there is no oxygen in space, so rockets must take oxygen with them.
Rockets carry onboard oxygen for combustion to generate thrust, so they can run out of oxygen if not enough is supplied. However, in space, rockets do not need oxygen from the atmosphere to operate as they bring their own supply. Once the oxygen stored onboard is consumed, the rocket will no longer be able to generate thrust and will not be able to maneuver or maintain its intended trajectory.
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
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.
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.
Spacecraft need an internal oxygen supply to provide a breathable atmosphere for astronauts during space travel. Since there is no oxygen in space, spacecraft must carry their own supply to support human life. This ensures that astronauts have the necessary oxygen to breathe and carry out their activities while in space.
Yes, rockets are vehicles that can carry humans into space. Crewed spacecraft such as the SpaceX Crew Dragon and the Russian Soyuz spacecraft are launched into space atop rockets like the Falcon 9 and Soyuz rockets. Once in space, these spacecraft can dock with the International Space Station or travel to other destinations in space.
