     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to the field of space launch vehicles. More particularly, the present invention relates to a space launch vehicle using magnetic levitation. 
     2. Description of Related Art Including Information Disclosed Under  37  CFR 1.97 and 37 CFR 1.98. 
     For decades the only viable way of sending a vehicle into space has been through rockets. These space rockets require a large amount of fuel to take off from the Earth&#39;s atmosphere, thus limiting the load that they can take into space, since a major portion of the rocket&#39;s weight is fuel. 
     A very significant part of this fuel is used up at the beginning, since a large amount of fuel is required to lift off the ship from its resting point. 
     For example, among rockets that consume solid fuel and liquid fuel (LH2-LOX), we can mention the Atlas V rocket, used to send satellites into space; they weigh 546,700 Kg, but can only carry to a geo-stationary orbit a maximum weight of 13,000 Kg. It can only carry about 2.4% of the rocket&#39;s weight as service weight. 
     Rockets such as Delta IV, weigh 733,400 Kg, and can carry to a geo-stationary orbit a maximum weight of 10,843 Kg, only about 1.48% of its weight. 
     Even the new generation of Ares rocket, such as Ares V, with a weight of 3,311,224 Kg, can carry to the moon a maximum service load of 53,070 Kg, approximately 1.6% of its weight. 
     So it is that current designs require, in summary, a large amount of fuel, thus limiting to a great extent the service load capacity that, in the most optimistic of cases, attain 2.4% of the weight. In order to do away with these and other problems, they thought about the development of this launcher.

     DETAILED DESCRIPTION OF THE INVENTION 
     In reference to said figures, we can describe a magnetic levitation system on which the magnetic coil of the track according to  FIG. 1  repels the vehicle magnets according to  FIG. 2 , which allows the vehicle to levitate as much as 10 centimeters from the rails, since there is no friction. 
     Once the vehicle levitates, power is supplied to the coils on the track to create magnetic fields that pull and push the vehicle along the track for the vehicle to move through it. Thus the electrical current that comes into the track coils is alternated to change the polarity of the magnetized coils so that the magnetic field on the vehicle front will pull it forward while the field in the rear will give it more thrust. 
     According to  FIG. 4 , the vehicle is 25 meters long, therefore if you wish to interconnect more vehicles, it can be done via an interconnection module described in that figure, to cover the necessary length of the spacecraft or rocket. 
     The spacecraft or rocket is placed on the vehicle mat or pad, therefore when it starts up with the rocket from the start of the track as shown in  FIG. 7 , it will not be driven by magnetic field, it will have no friction. 
     On the track, according to  FIG. 6 , the vehicle starts driven by magnetic fields, thus avoiding the use of fuel by the rocket to take off from its resting point; the vehicle runs through the track at zero degrees of inclination. When the track starts to incline, the rocket or spacecraft starts up its engines, so that when it arrives at the end of the track, it will have sufficient speed to continue lifting up on its own. 
     The track will release the rocket when it reaches a height of 800 meters and there is an angle of 57 degrees—the desired angle to reach places such as the International Space Station (ISS), the rocket will be secured to the vehicle by bolts with explosives, such as those used on the space shuttle to secure it the launching pad, which when the first vehicle arrives at the maximum track height released the rocket or the spacecraft so that it will run with its own engines. 
     When the vehicle breaks off the spacecraft or rocket and at the end of the track, the rocket will shoot out, so that in order to reduce its speed, a vehicle air brake is used as the one described in  FIG. 5 , in order to reduce speed to subsequently open 4 parachutes according to  FIG. 3 , providing a smooth descent to use again the vehicle in another takeoff. 
     Thus, a magnetic levitation space launch vehicle is obtained with the following characteristics: 
     It has no friction, since this way a magnetic levitation space launch vehicle is obtained with the following characteristics: 
     a) It levitates on the track. 
     b) The spacecraft or rocket takes off from its resting point via magnetic levitation; therefore, this becomes a major fuel saving. 
     c) It is reusable. 
     d) The spacecraft or rocket shoots out at 57 degrees; therefore, it does not have to adjust its inclination as in the case of conventional rockets, which is also fuel savings. 
     e) It is modulable, since several vehicles can be interconnected in order to carry spacecrafts or rockets of different sizes. 
     In view of all of the above-stated, one can say that no space launch vehicle presently used has these characteristics.
