You can bounce off the atmosphere if your craft's speed is higher than escape velocity at the height of the bounce and the hyper aerodynamics of the craft allow you to hyper glide. This will occur if the craft is some form of hyper sonic waverider as a waverider generates lift. how do you say chemistry in spanishWebInclination: Angle formed between the orbit of the satellite and terrestrial line of the equator. Satellites with inclination of 0 degrees follow the equator line and are called equatorial orbit satellites.
