ESA's PILOT-D navigation demonstration camera was planned to be flown on this mission, but is already being procured from a commercial service provider and will fly along with them on their mission,[27] due to continued international collaboration having been thrown into doubt by the 2022 Russian invasion of Ukraine and related sanctions on Russia.[28][29] The demonstrative instrument was supposed to collect data for the landing of other missions and was therefore not part of the probe's operating system.[30]
Doesn't sound like it was a critical part of the mission.
Hopefully they can land without it, provided they can recover from this current mishap. Any success in space is good for science.
Supposedly they have another landing instrument, though I suspect the camera was somewhat important for selecting a landing site. The Doppler speed and range meter is discussed briefly here:
According to the original plan, Luna 25 was supposed to be launched in 2014. However, various reasons provoked delays one after another. The last big postponement (from 2021 to 2023) was caused by the malfunction detected in the Doppler speed and range meter (DISD-LR) during the tests. Being an important part of the soft landing system, this device couldn’t be ignored, and its insufficient accuracy may cost a mission. The repeated tests of DISD-LR and subsequent changes of the lander’s software caused a delay for almost two years.
Exactly. Would be a shame if it goes to waste.
But it sure seems pretty doomed.
"During the operation, an abnormal situation occurred on board the automatic station, which did not allow the manoeuvre to be performed with the specified parameters," Roskosmos said in a short statement.
Thanks!

It didn't make it.

Monday will bring some answers.
/edit Nevermind. It's gone
