They stack about 500,000 blondes and then the satellite is handed up and up until the last blonde hands it to an astronaut ,near space.

Determine how much energy a satellite in the desired orbit will have (this includes kinetic energy and potential energy).
Determine how much energy the satellite will have before launch (since it's on the Earth's surface and the Earth's surface is moving, the satellite has some kinetic energy and potential energy even before it's launched).
Determine a strategy for adding energy to the satellite's orbit. Potential energy is based on position, so unless you invent teleportation, you can't change the potential energy instaneously. Kinetic energy comes from motion, so increasing an object's velocity increases its kinetic energy, which increases the size of the orbit (the potential energy increases as the satellite moves further away from Earth).
When you fire the rocket to add kinetic energy, it creates a new, bigger orbit, but the new orbit has to pass through the same point that you were at when you fired your rocket. In other words, if you start out in a small circular orbit, all you did was to make the opposite side of your orbit further away - you created an elliptical orbit. That means you'll need to fire the rockets again when you reach the far side of your orbit (apogee) in order to turn your final orbit into a bigger circle.
The initial launch is a little more complicated, since, if the Earth had no atmosphere and there were no neighbors to annoy, the best way to launch your satellite and rocket would be with the rocket and satellite laying on their side. Instead, rockets have to be launched nearly straight up to reduce the amount of time they spend in the atmosphere (and the amount of friction caused by the atmosphere), but have to slowly tilt so that by time they reach their desired altitude, the rocket is nearly horizontal relative to the Earth.

Imagine this, when you throw a rock horizontally above the ground level, the rock travels some distance before it loses its velocity and then falls back to the ground. The rock falls to the ground because of the pull of gravity, and it loses velocity because there is friction with the thin air . Now, you throw the same rock at a higher velocity, and the rock will travel some greater distance before it falls back to the ground. This time, you will shoot the rock with a velocity where it will reach outer space. Once this rock gets to outer space, there is no friction from air, so this rock will maintain its constant velocity. However, the pull from earth gravity is still present, and this will keep the rock circling or orbiting around the earth. Then you will have a satellite. It is the same concept that NASA uses to put satellites into orbit with much more sotisphicate equipments and calculations.

The satellites are launced using a rocket to a specific distance above the Earth's surface that allows the satellite to orbit the Earth rather than spinning off into space or falling back down.

very just about, as low as workable. The Oberth effect dictates, interior the main classic words, that the closer a spacecraft is to an merchandise, the greater effective effortlessly it may possibly enhance up. The craft would not even might desire to make an entire orbit of Earth; it may probably initiate its acceleration to flee velocity the 2nd it reaches LEO.

With rockets. They shoot them up on the tip of a rocket then the rocket engine breaks off when the statelite is at the correct altitude and the earths gravitational pull keeps it in orbit.

The scientists at Cape Canaveral use a tremendous slingshot utilizing the worlds largest rubber band. This is a joke right? Your really not that stupid that you would ask such an idiotic question , right?
