Chemical rockets must carry oxygen, an oxidizing chemical, or a propellant containing its own oxygen. This is because the concentration of oxygen in the air (even at lower altitudes) is insufficient for the rapid and complete combustion of the rocket fuel. Once a rocket reaches higher altitudes, there is even less oxygen to use.
Some proposals for high-speed aircraft include a hypersonic form of "ramjet" that would force large amounts of air into intake vents to provide oxygen to the fuel. This concept, called the SCRAMJET (for supersonic combustion ramjet) is still in the experimental stages, but could provide a cheaper way to attain Earth orbit.
What else can I help you with?
Does a rocket fall back if it runs out of oxygen?
No. A rocket does not need to fire its engines to stay in orbit. It does, however need fuel and oxygen to perform any maneuvers, so a rocket that runs out of oxygen will be stranded in space.
Does a rocket need oxygen to lift off?
Yea
What astronauts need to go to space?
you will need a spacesuit, food/drink,clothing,rocket,spaceship &plenty of oxygen
Why is a jet called a air breathing engine?
A jet engine uses fuel from the aircraft's fuel tanks, but gets its oxidizer from oxygen in the air. So it won't work in space, where there is no air. A similar engine that carried its own oxygen would be called a "rocket", and WOULD work in space - because it wouldn't need air.
What kind equipment does a rocket carry?
it carries food,the oxygen tank and some things astronauts need

Why is there a difference in the way oxygen and carbon dioxide are transported by the circulatory system?
Oxygen is primarily carried by hemoglobin in red blood cells, while carbon dioxide is carried in three forms: dissolved in plasma, bound to hemoglobin, and as bicarbonate ions in the blood. This difference in transport mechanisms is due to their different chemical properties and the body's need to efficiently transport and exchange these gases in the lungs and tissues.
What would you need to go to Mars?
You would need a rocket ship in order to travel to Mars. You would also need a space suit and an oxygen tank.
Why do rockets carry oxygen into space?
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.
What two things do body cells need for respiration where are these things carried and how do the two things needed get into cells?
Body cells need oxygen and glucose for respiration. Oxygen is carried by red blood cells in the bloodstream, while glucose is carried as blood sugar in the bloodstream. Both oxygen and glucose enter cells through their respective transporters: oxygen enters through respiratory membranes, and glucose enters through glucose transporters in the cell membrane.
A chemical that contains a metal carbon and oxygen only?
i need to know what it is please
Which chemical reduces oxygen in the blood causing a difference between the amount of oxygen the cells need and the amount of oxygen the blood can supply?
carbon monoxide.
