उत्तर
We use space launch technology to propel the spacecraft into outer space, defying gravity. It requires a tremendous amount of energy to launch the spacecraft, which is thousands of tons in weight. This energy is obtained through the burning of an ample quantity of fuel present in the rocket. Thus, rockets are used to launch the spacecraft in space travel.
