The launch of the automatic station "Luna-25" took place on August 11. According to the plan, it was supposed to land on the moon tomorrow, August 21, but something went wrong yesterday already.
According to the «Luna-25» flight program, a pulse was issued at 14:10 for the station to transition to a pre-landing orbit. During the operation, an emergency situation occurred on board the automatic station, which did not allow the maneuver to be performed with the set parameters.Currently, situation analysis is being conducted by the control group.

Last night, the first data appeared that "Luna-25" had crashed, and now the crash has been confirmed by "Roscosmos".
On August 19th, according to the «Luna-25» spacecraft flight program, a pulse was scheduled to form its pre-landing elliptical orbit.About 14:57 MSK contact with the «Luna-25» was lost.Efforts carried out on 19 and 20 August to find the spacecraft and make contact were unsuccessful.According to preliminary analysis, due to the deviation of the actual impulse parameters from the calculated ones, the spacecraft switched to an unscheduled orbit and ceased to exist as a result of collision with the lunar surface.The issue of clarifying the reasons for the loss of the «Luna» will be addressed by a specially formed interdepartmental commission.
