On August 20, Roscosmos said that Luna-25 module crashed into the moon's surface after going into an unplanned orbit. Communication with the spacecraft was lost at around 2:57 p.m. Moscow time (11:57 GMT) on August 19. "The correction engine has not stopped working according to the information from the accelerometer, this is the device that shows the change in speed. The reason is that the accelerometers did not turn on. Why they did not turn on, we are looking into it in detail now," Borisov said at a news conference. Currently, there are 16 preliminary causes for the crash, 11 of which have already been checked, and the examination into the causes of the Luna-25 crash is planned to be completed by the end of September, the official added. The first person to convey words of support in connection with the accident was NASA Administrator Bill Nelson, Borisov said.Roscosmos earlier detailed that the landing module crashed because the engine failed to turn off as program, having worked 127 seconds instead of 84 seconds during a transition to pre-landing orbit.However, despite the unsuccessful landing, Russian authorities have underscored that the mission has provided invaluable information to the assignment.
