Your question is very broad. One of the things a rocket takes off from is called a launch pad. Launch pads are the place where rockets take off. But the things that cause it to take off are completely different. A rocket takes off or 'launches' from a concept called thrust. Thrust is when say I have a ten pound ball that I want to throw directly up in the air. I need to create 10 pounds of energy to launch it and then enough energy to actually get it to where I want to go. Those are the basic things that make a rocket launch.
The space shuttle took about 8.5 minutes to reach orbit after launch. The first stage of the rocket engines provided most of the thrust for the initial portion of the ascent, and the solid rocket boosters provided additional thrust for the first two minutes of flight.
burning fuel (rocket propellant)
A rocket takes off by igniting its engines, which produce thrust that propels the rocket upward. The main forces involved in the rocket's takeoff are thrust and gravity. Thrust overcomes gravity, allowing the rocket to lift off the ground and travel into space.
The space shuttle has to start straight up, like a rocket.

Actually its the other way around, if a rocket were to launch off the moon it would take less fuel than if it had launched off of earth. It would take less fuel because the moon has lighter gravity.
The Space Shuttle Challenger used approximately 1.3 million gallons (about 4.9 million liters) of propellant for its launch. This included about 500,000 gallons of liquid oxygen and 200,000 gallons of liquid hydrogen in its main fuel tank, along with the solid rocket boosters that provided additional thrust. The total thrust produced at launch was about 7.8 million pounds. This massive fuel requirement was necessary to overcome Earth's gravitational pull and propel the shuttle into orbit.
Launching a rocket to the moon requires a tremendous amount of energy. Roughly speaking, it takes around 7-8 million pounds of thrust to propel a spacecraft out of Earth's gravity. The total energy needed can vary based on the rocket design and mission profile, but it is estimated to be in the range of billions of joules.
If the thrust of the rocket at take-off is not enough to put the rocket in orbit around the Earth, it will not be able to overcome the gravitational pull of the Earth and achieve the necessary velocity to stay in orbit. The rocket would likely fall back to Earth due to gravity.
Any amount of thrust that's greater than the weight of the rocket vehicle will lift it off of the ground and accelerate it upward. If you keep it up long enough, the vehicle will be in space.
Thrust Capacity is how much thrust it can take :D
A rocket needs a large thrust on takeoff from Earth to overcome the force of gravity pulling it down. The large thrust is necessary to generate enough speed to reach escape velocity and break free from Earth's gravitational pull. Once the rocket is in space, it needs less thrust to maintain its course.
