Must be a major onboard programming error then

Or bad maneuver data from the ground.

"Engine failure" is a bit severe for the engine. Looks like it performed too well ! It probably never received the cutoff command and burned all its fuel like an honest rocket engine is supposed to do

I don't think so, otherwise the plan would be to land with only 43 seconds of prop.

I'm sorry, this is total BS.
How is putting a little unmanned probe (something several nations have done) harder than sending humans back to the moon, to stay this time?
And may I remind you, Artemis 1, even though it was not supposed to land, completed it's design mission perfectly.

the mission is so difficult that it was necessary to temporarily evacuate the population from the houses, as the rocket took off in the opposite direction

no one has ever been able to land the apparatus, but the pole of the Moon

 

[Sunhillow]

The main difficulty is to get into a polar orbit around moon, which seems to have worked. From there on a landing should not be too different from landing out of a more or less equatorial orbit.

Isn't Vostochny supposed to replace Baikonur, and wasn't that location chosen because of the access to 51.6º orbits? Luna 25 was launched into a 51.7º orbit, so I guess that those people will have to be evacuated every time there is a launch from Vostochny to the ISS.... Anyway, so no extra difficulty there. And the rocket didn't go in the "opposite direction", the spy sats usually launched from Vostochny go North, Luna 25 went East, which is "standard".

no one has ever been able to land the apparatus, but the pole of the Moon

Completely irrelevant for Luna 25 at the time it failed. It was (simply) changing orbits.

57º South... a bit more than I expected.

Ah, but that worked fine.
And you say an unusual launch azimuth is harder than sending a human landing system the the south pole, and building a space station in DRO?

no one has ever been able to land the apparatus, but the pole of the Moon

As said before, totally irrelevant. And NASA is sending humans to the exact same place.
No one had landed humans on the moon, until NASA did it in 1969-1972.

All you are trying to do is make yourself feel better about your country's space program.

I'm not interested in an argument, you took my message, which I sent to Thunder Chicken, which had a painful joy from a failed mission

 

[Max-Q]

I'm not interested in an argument

I'm not either, it just felt like you were attacking my country's space program.
It's all good

 

[llarian]

Take it private, guys.

We‘re finished, sorry.

We all love failures more than boring successes for some reasons:

• You can learn more from a (unlucky?) failure than from a (lucky?) success. See survivor bias there.
• Popcorn
• The comic book store guy: "Worst space program ever." (Even if it isn't)
• Seeing all the hype, PR, astro turf and marketing suddenly vaporize and leaving just engineering behind.
• Did I say popcorn already?
• A "bembel" with "Epplewoi" is of course also fine.
• Plain Schadenfreude and Weltschmerz. I know you want it.

successful results, turning on devices

Госкорпорация «Роскосмос»

🔴 Первые результаты работы научных приборов автоматической станции «Луна-25» на окололунной орбите Во время полета проведено несколько включений научной аппаратуры, созданной в ИКИ РАН. Анализируя их данные, получены следующие результаты: ▪️ В энергетическом спектре гамма-лучей нейтронный и...

also register a meteorite impact on the moon, which is incredible luck

Станция «Луна-25» зафиксировала удар микрометеорита о поверхность естественного спутника Земли. Новости. Первый канал

Так настоящей удачей для ученых стало то, что датчики зафиксировали удар микрометеорита о поверхность естественного спутника Земли. Специалисты говорят — космическая частица, скорее всего, принадлежит метеорному потоку Персеиды.

results obtained allow us to accelerate the development of "Luna-26" and "Luna-27" (missions will start earlier)

Работы по миссиям "Луна-26" и "Луна-27" будут форсироваться

Of course, the article does not mention how the development and schedule is accelerated...

But that would require that a flight prototype was constructed for the mission, which is rather unusual in Russian spaceflight. The procedure more common in the western world, and became even here unusual in the late 1990s, due to the higher costs over a classic subsystem mockup.
