Soyuz-2.1b/Fregat - Luna-25 (Luna-Glob) - Vostochny - 10 August 2023 - 23:10 UTC

[PM3]

Anatoly Zak reports that a launch in 2021 is very unlikely, due to delays in systems development.

I hear the same story:
The current launch date is not realistic, they expect slip of 4-6 months.

Has anyone calculated and shared launch windows beyond October 1 and 31, 2021?

... and May for Nauka. -_-

Just political show dates, not launch dates.

What source says Fregat MT ??

[Steven Pietrobon]

What source says Fregat MT ??

I don't know, but I believe it should be just Fregat, as Fregat MT is only used by Soyuz-ST.

In 2015 mockup was displayed with Fregat-SB.

Is that the source of confusion?

The Fregat SB was used together with the Zenit-3, wasn't it ?

But here (2015) they talk about "Fregat"

The source of confusion was before Geopolitical fighting the flight was planned on Zenit-2SB (Fregat SB)
Fregat SB was only employed on Zenit as Soyuz-2 family's upgrade path was frozen/shelved to pursue its replacement rocket fmaily which will use optional Fregat SBU, Briz-(M2, L et al) and Blok-DM family on Soyuz-5,6,7 family.

Fregat-MT was announced before it switched to planning to fly the Phobos-Grunt Flagman flight spare which is a hybrid of the Fregat SB and Fregat-MT upper stages. It was then switched back to Fregat-MT but since flying from Russia all versions are called just Fregat these days. Anatoly Zak only just updated his entry to remove the MT reference.

The post by @Stan Black in the Fregat thread is perhaps interesting in this context.

The linked picture shows Luna-Glob with a classic Fregat in a tight 14С737 fairing.
The unfortunate 122-01 was originally planned.

The version of Fregat for this flight has changed so many times that launch processing is nowadays when you clearly know.

The 2011 contract documents for the Fregat indicate ПхО 14С227; and the wording is similar to those for Rezonans.

Volga-Dnepr transports spacecraft scale model for testing
30 / 04 / 2021

Volga-Dnepr Airlines has delivered a Luna-25 full-scale mock-up from Moscow (Russia) to Blagoveshchensk (Russia) onboard an AN-124-100 freighter.

A five-tonne full-scale overall assembly of Luna-25 spacecraft designed and manufactured by NPO Lavochkin, one of the leading aerospace companies, was transported to Ignatyevo airport for further trucking to the Vostochny Cosmodrome. The mockup is intended for complex tests of technical means and systems at the cosmodrome.

Interview with Rogozin at Roscosmos site:

Fragment on Luna-25 plans:

{Question}
— В этом году планируется отправка «Луны-25». 27 мая гендиректор РКЦ «Прогресс» Дмитрий Баранов сообщил, что в октябре с космодрома Восточный может быть запущена еще одна ракета «Союз». Может ли Восточный обеспечить два пуска ракет «Союз» с Восточного в октябре? И как обстоят дела с «Луной-25», поставлены ли приборы, необходимые для мягкой посадки?
{Answer}
— Наиболее приемлемое и безопасное пусковое окно, чтобы лететь на Луну — примерно с мая по конец октября. К сожалению, мы сейчас зажаты тем, что рассчитываем успеть именно в октябрьское пусковое окно, у нас нет запаса прочности по времени в рамках графика. Есть ключевые поставки, которые мы должны получить и интегрировать в этот аппарат, от которых зависит, успеваем или не успеваем. Концерн «Вега» Госкорпорации «Ростех» должен поставить один компонент и европейские коллеги должны поставить прибор «Пилот-Д», который тоже должен быть интегрирован, сертифицирован и должен пройти полную проверку на электромагнитную совместимость.

В августе мы поймем точно, что получается по срокам. Второе пусковое окно — это февраль 2022 года и третье — это май 2022 года. Февральское окно мы отметаем, потому что там придется делать очень сложные орбитальные «телодвижения». Пока мы исходим из того, что основное — это октябрь 2021 года. Если в августе мы подтверждаем, что НПО Лавочкина выходит на стартовую готовность, тогда дополнительный пуск с Восточного мы просто не успеем провести. Если же у нас будет перенос на резервное пусковое окно, тогда мы запустим с Восточного еще одну коммерческую ракету.

So basically this means the launch is slipping to NET May 2022.
They did NOT say it explicitly yet, however the language is quite typical for an "imminent schedule correction"

IMHO, now it is safe to remove "?" from the title.

Bing translation.

"This year we plan to send Luna 25. On May 27, Dmitri Baranov, director general of the Progress RSC, said that another Soyuz rocket could be launched from the Vostochny Cosmodrome in October. Can the Oriental provide two launches of Soyuz missiles from the East in October? And what about the Luna 25, are the devices needed for a soft landing supplied?
{Answer}
The most acceptable and safe launch window to fly to the moon is from about May to the end of October. Unfortunately, we are now squeezed by the fact that we expect to have time in the October launch window, we do not have a margin of safety in time within the schedule. There are key supplies that we need to get and integrate into this machine, on which depends, do not have time or do not have time. The Vega concern of the Rostec State Corporation must supply one component and European colleagues must supply the Pilot-D device, which must also be integrated, certified and must pass a full test for electromagnetic compatibility.

In August, we will know exactly what happens in terms of timing. The second launch window is February 2022 and the third is May 2022. We tick the February window because we will have to do very complex orbital "body movements" there. So far, we believe that the main thing is October 2021. If in August we confirm that the NGO Lavochkina is on the starting readiness, then we simply will not have time to carry out an additional launch from the East. If we have a transfer to the backup launch window, then we will launch another commercial missile from the East.
