How do space shuttles get out of earth atmosphere?

Answer 1

escape velocity of the earth is around 11km per sec so the shuttle would need to travel around 22times the speed of sound to get into orbit

If your doing a space project at school, you can use some of these ideas:

The 3 Main Components Of The Space Shuttle

The Rocket Boosters:

The Rocket Boosters are 2 parallel boosters filled with solid rocket fuel similar to fireworks or gun powder attached to the side of the liquid fuel tank with explosive mounts and they provide 80% of the thrust to launch the space vehicle from the platform. The Rocket Boosters are only used throughout the first 2 minutes during the take off, once they are ignited, they cannot be stopped, the mission must continue. After they are empty the rocket boosters are jettisoned by exploding the mounts off the solid boosters so they can fall back to earth with parachutes and be picked up to be reused.

The Propellant Tank:

The Propellant Tank is the biggest part of the space shuttle. It carries the two solid rocket boosters and the space shuttle itself. It is filled with the liquid fuel and oxygen the shuttle needs to carry itself into space where there is no oxygen. After the solid boosters are jettisoned, the liquid fuel is the only thrust the shuttle has to drive it, so that when it exits the Earth's atmosphere and has reached its altitude the shuttle has no further use for it because it has enough fuel to complete the mission in its own tanks so the propellant tank falls back to earth to be reused again.

The Orbiter:

The Orbiter is the main part that transports the astronauts and pay load to space. The space shuttle is another name for the orbiter. In space there is zero gravity, so the space shuttle will drift around the Earth. In the orbiter is a life support system that holds oxygen, electricity, and things they need throughout the journey, computer systems, etc. When it's time to come back to Earth the shuttle enters the Earths atmosphere at 16,000 mph and uses it heat shield to protect it from certain destruction and to slow the vehicle down enough so that it can glide safely back to its Earth base using no power from its engines.

How They Work Altogether:

All the space shuttle systems work together because without one of them, the space shuttle's mission could not begin. Firstly, if there was just a propellant tank, it wouldn't work because it doesn't have enough power to thrust off the ground and no one would be able to experience space because you can't go inside the propellant tank because it's just like going inside the petrol tank of a car. Secondly, if it were just rocket boosters, no one be able to experience it, again, because it's just like going inside the engine but the rocket boosters would be able to lift off, if computerized. Thirdly and most importantly, if it were only the orbiter, it would not lift up because of its power cannot make it thrust off the ground like rocket boosters. Lastly, they all work together to finish the mission. Rocket boosters boost it off the ground, the propellant tank holds the oxygen and the liquid fuel and the orbiter carries the payload and humans, with all the systems. That's how they all work together, making their job get done and finishing their mission!

The 'Crawler'

The Crawler is the mobile launch pad and the transporter and looks like a very large transportable multi - purpose platform. It transports the space shuttle very slowly, so that it doesn't fall off the crawler. The crawler moves along a track created for itself to get to its destination ready for launch close to the ocean, so when the space shuttle launches off, the rocket boosters and propellant tank jettison off the space shuttle into the ocean. If there were no such thing as a crawler, they would have to build the space shuttle on the ground and set it up outside.
