Abstract: In space research, rockets are used to explore the space and also rockets uses fuel to travel in space. Here the proposed Slingshot mechanism can be used in space research and to travel without fuel. The comparison of basic model of rocket and slingshot mechanism is made in this paper. Rocket uses fuel to go into the space. Whereas slingshot based space rocket launcher is an advance technology used to explore in space without using fuel. This mechanism can be used to send satellites and capsules to the planets.
