According to Interfax, "debris of Meridian satellite were found in Ordynsky district of Novosibirsk territory" (Ordynskoye is located at 54.37N, 81.9E).

The crash site is closed off.

Phew, it didn't cross the border, after all.

upd: If it had flown 150 km more downrange, it could have hit the roof of my previous home in Barnaul.

Okay, the scenario crashed right in the middle of it. When I stopped the engines at T+ 425, I was at 50.63 N, 83.17 E, at an altitude of 176.0 Kilometers.

Which scenario are you using? If you are using the Soyuz U/FG add-on, there are two problems:

1. It would mean you are trying to launch from Baikonur. This launch is from another launch site, Plesetsk.

2. The rocket launched today, the Soyuz-2-1b, has a new third stage engine that has better efficiency (ISP 357s, compared with 325s of the RD-0110). This is different from the rockets in the add-on (Soyuz U/FG/2-1a).

Ok, we are short of a proper addon, I see.

Edit: Short of a proper addon is correct.

Angry Popovkin's reaction....

Bad PR from Popovkin: in the post-docking media briefing of the Soyuz TMA-03M, he tried to avert all questions about the failure. When the reporters ask one by one, he answered that the industry is still in the process of recovering (bad tracking systems, young workforce etc. etc.), then after the congratulation messages from NASA and ESA, he angrily walked out of the press room without answering the last question from a reporter about the accident!

Mmh... at least it was "only" a miltary launch... It probably shows that the issues with quality control are not over yet...

Looks like a large fragment from the rocket hit through the roof of a house! (no injuries reported)

Edit: Looks like the site of the fallout is at 54.372559 N, 81.865196 E.

The known location of the found piece of debris is Vagaitsevo village in Ordynsky district. The following is just topping over my mind!

http://www.lifenews.ru/news/77860

Quote:
"The debris fell 3 km away from the district's centre right on a residential house in Vagaitsevo village. During impact of a titanium piece measuring 1 meter in diameter a family was in the living room. At present moment, a teams from Army and Federal Securiy Service are working at the scene", said a source in the territorial Emergency Command.

The heavy piece of metal accelerated to a great speed fell on the house's roof like a meteorite. Now all people are evacuated, the scene is under examination.

Accroding to eyewitnesses, a huge fireball plummeted down from the sky, hitting on a roof of a small house. The home's owner Andrey at that moment went out to take firewood for his oven, while his wife and kids stayed inside.

Now servicemen from the local FSS have already extracted a piece of the satellite from the destroyed house. It looks like a metal ball with 50 cm radius.
People at NK say it's most likely a pressure tank from the Block I.

Not just from any reporter. I didn't see the TV coverage but if she said she was from NK she's either Yulia or Katya (Yulia Ecomonova or - more likey - Yekaterina Zemlyakova).

It appears that an engine failure can be confirmed by existing telemetry data. According to a poster at NK:

http://www.novosti-kosmonavtiki.ru/p...=859765#859765

Quote:
I have observed the process as non-participant, but closely. According to reports from the range tracking, the two first stages worked fine. After T+288 the 3rd stage engine has begun burning. After the stack arrived within reach from Khimki, Fregat telemetry began coming through the antenna at Lavochkin. Before T+425 everything went normally. At this mark, the signal has significantly dropped in volume and the telemetry has shown the gyro-platform gymbal lock in 5 seconds, and this would only be possible if the stack had swayed by no less than 40 degrees. It could happen if the object has strongly tumbled. It seems to me, such dynamics can only follow an engine's explosion. I can't think of any other explanation.

User granat from Russian astronomy forum has made a series of pictures from Yarovoyue (Altai region), 52.93N, 78.58E. It makes the disaster development visible. The time marks are UTC+7.
