Space gun-a device for launching objects in space. It refers to rocket-free methods of output objects into orbit. Space gun is not able to deliver the object in stationary orbit around the planet, for this, it must be equipped with a rocket engine to adjust the course after launch the object. This makes it possible to replace the existing excessively expensive rocket systems with new methods of delivering payload (space gun). Thus, the costs of scientific programs are decreasing at times, and many studies are becoming available, less risky and environmentally safer.
