After separation of the spacecraft from the third stage carrier “Progress” was an unplanned orbit. According to the American SKKP in space were also about 20 fragments of the third stage of the launch vehicle.
The attempts to take control of the ship to come to nothing lead. He began with uncontrolled descent of the orbit, and then entered the dense layers of the atmosphere, and on May 8 ceased to exist at the southern coast of Chile.
