Roskosmos announced an emergency situation with an automatic interplanetary station
Communication with Luna-25 was lost, it became known on Saturday evening, after Roscosmos reported about an emergency situation with braking. If there is a possibility that the device is still in the orbit of the Moon, then it is very scanty.
“Today, in accordance with the Luna-25 AMS flight program, at 14:10 Moscow time, an impulse was issued to transfer the station to the 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 specified parameters, ”the state corporation reported. And a little later, rumors leaked out that things could be much worse.
We asked a specialist from the industry to comment on the situation, and this is what he answered us:
– The braking impulse was given to the station in order to slightly reduce perileunes – the lunar perigee, in order to bring the moment of a successful landing closer. However, the propulsion system worked out an impulse one and a half times more than it should. If this is true, then the station could enter an open orbit of descent…
– In other words, fly past or fall on the moon?
– I don’t want to believe it, but the lack of communication with the device can only speak of the second.
– A day earlier, information from the Space Research Institute of the Russian Academy of Sciences appeared about the detection of a micrometeorite impact by the PML device, designed to detect microparticles on the Moon. Could he have caused an emergency?
– Not. I think that scientists should have calculated this risk and prepared the apparatus for it in the first place.
What could have caused the emergency? Is it bad software, hardware or human factor?
– It is not yet clear why this happened, there did not seem to be any errors in the calculations. There may be a problem with the communication system or with the control. And the human factor can never be ruled out. Now there is a “debriefing”.
As it became known, in the evening, after reporting an emergency situation with the station “Luna-25” in the NPO. Lavochkin, from where the apparatus was controlled, Alexander Ivanov, First Deputy General Director of Roscosmos for the development of the orbital group and promising projects, arrived to hold an emergency meeting on the situation with Luna-25.
