After this tragic accident of Colombia's shuttle the continuance of these spatial functions were encountered with ambiguity and lots of suspicion was formed in the NASA officer's brain. The burst was formed because of the defect which was made in the outer insulator fuel tank, a insignificant piece of insulator that was separated while throwing the Colombia's shuttle from the fuel tank under the aerodynamical force of throw (while separating the tank from the shuttle) and it hurts the ledge of the left wing of the shuttle in the place of ceramics insulator defect and shuttle's thermal safety system. It was happened in throwing the shuttle discovery too, however they relief the damaged parts through a spatial marcher in the space and they turn it to the earth with so much presentiment. In this essay we present a new design for the fuel tank and shuttle. In this model, shuttle is set on the top of the fuel tank and while separating the tank from the shuttle, the probable separating pieces, wouldn't be defect to the shuttle. In this procedure because the tank has a motor, a cart landing and a control system, it is again useful and would make the economy in the charges. In this Method by putting shuttle on top of the tank, it may not make any hurt to the thermal shield and there weren't any accident accession like the Colombia's shuttle accident and There wouldn't be any requirement to design a new space crafts with the passenger to go and return, and according the heavy costs of the researches, temptation and long time providence it would be much and According to probability of returning the fuel tank to the earth, in other throwing there would be multiple providence that can be a justification for this project And also Changing the tank place improves the aerodynamical coefficient in comparison present shuttle's picture that will cause to reduce using the fuel.
