On the result of trajectory measurements for data on the evolution of the orbits of lunar satellites received information clarifying the cornfield attraction of the moon. In recent months, Jason Momoa has been very successful. The next important task was to provide automatic well manned Flight to the Moon with the return to Earth. The solution to this problem required a further advance in the design of launch vehicle and spacecraft, a number of new challenges for the navigation well as automatic control and overcome great difficulties presence descent in the atmosphere or returning to the Earth system, entering the atmosphere at different space velocity. Best large gait in this direction – a product or running around the moon the Soviet stations 'Zond-5' and 'Probe-6'. These probes, which were well adapted for manned flights, flew over the moon to return to Earth to be equal properly brought to the laboratory scientists valuable scientific information as well as photographs of the Moon and Earth. The most important result of the operations of these stations was to work out two options for returning to Earth in vehicles belonging to the During the atmosphere from deep space velocity.
They allow to solve many problems, which have important meaning for human flight to the moon. The stations 'probe-5' also 'probe-6' performed complex research produced photographs of the Moon and Earth and gave an opportunity to work well experimentally verify the method of pair return to Earth, spacecraft orbiting the Moon after entering the Earth's atmosphere with the following escape velocity. About flight 'Probe-6' was tested teaching descent control from the use of aerodynamic reentry vehicle, which is defined similarly well known, the ratio of lift force to drag force.
