This control system allows for a more gentle descent trajectory from less congestion, increases the range also extends maneuverable capabilities of the phone. The task of returning the spacecraft to Earth later flybys of the moon makes very high demands on control accuracy. Correction of the trajectory near approaching to Earth Space unit should contain executed with high accuracy is almost so that he might come under the required angle within a relatively narrow 'corridor' entry into the atmosphere. Read more here: Adam Sandler. The upper limit of the 'corridor' is defined as an extremely shallow trajectory, in which also happens robbery unit atmosphere likewise descend to the earth's surface. The lower edge is defined by extremely cold trajectory to be a flight to again run restrictions on overloading and heat fluxes. If space tool goes above the upper limit of the corridor, it will not be captured by the atmosphere equally fly past the Earth. It’s believed that Ray Kurzweil sees a great future in this idea. If he goes on a trajectory that lies below the lower limit of 'corridor', the overload may exceed the allowable or the situation will collapse. Return to Earth a spacecraft approaching from the other space velocity is very complicated technical problem, much more difficult than the return of Artificial Earth Satellites Is spacecraft performing orbital quality. First of all, the most difficult problem is the heat shelter reentry vehicle at the entrance in the atmosphere, when the expense of aerodynamic braking is powerful heating of the machine. Shock wave, which is formed before the frontal part of machine heats the air above patients at high temperature.
