Short description
Summarize this content to 100 words The extraordinary situation occurred during the execution of the planned operation during the transition of the automatic station “Misyats-25” to the pre-landing orbit, the situation is being analyzed, Roscosmos reported. According to the specialists of the Center for the Study of the Moon, “Misyats-25” could not perform the necessary maneuver in the lunar orbit with the specified parameters. It is likely that the August 21 landing procedure in the previously designated area may be in doubt. Today, according to the flight program, at 2:10 p.m. Moscow time, the automatic station “Misyats-25” gave an impulse for the transition to the pre-landing orbit. During the operation, an extraordinary situation occurred on board the automatic station, which prevented the maneuver with the specified parameters.Currently, the specialists of the management group are analyzing the situation. It was planned that on August 19, on the third day after entering the moon’s orbit, the specialists of the Center for the Development of the Space Center will form the final version of the landing orbit for the station, and the device will begin the exit maneuver according to these data. The orbit was supposed to be elliptical, and when passing perihelion (the point at the minimum distance from the Moon), the device had to be only 18 km from the surface of the Earth’s satellite. In this orbit, the spacecraft was supposed to spend another two days until August 21, making 24 turns. The amount of fuel on board the Moon-25 after entering the lunar orbit became very limited. According to experts, the station does not have a significant reserve of fuel in case of additional or unforeseen maneuvers.According to unofficial information, communication with the apparatus was lost after the start of the maneuver.Digest of the events of the Luna-25 project from the launch on August 11 to August 19. There are 2 days left before landing, but now there are problems at the station.
