20 km East from Dzhezkzagan.

Auto-translation:

Quote
To find out the reason for the accident on the SOYUZ-FG ph My decision was formed by the state Commission. She's already started her Work. Telemetry is Studied. Rescue services work from the first second of the Accident. The Soyuz-ms emergency Rescue system Worked. The crew is Saved.

Here's hoping Mr. Trampoline gets fired after this incident.

If you look closely at precisely 2:20 in the video you see the first object departing the stack, although it's less obvious than in the NASA TV feed. Four seconds later the boosters cut off (nominally) and about a second later the deflagration starts.

Per Anatoly's image above your post, this was the nominal separation of the SAS escape tower.

Surrounding area. Looks like a few lakes in there.

What implications does this have for future crew rotations? With presumably no capability to launch crew, is it likely they will extend expedition 56 or bring them home on time and leave the space station with no crew?

Doh! Here's the correct location.

To early to tell, but Soyuz stay in orbit is limited, so they have to come down after around 200 days....

So it is possible that there will be no crew aboard ISS starting December

Closer view. Area looks pretty barren.

You're very right, I was looking at the TMA ascent timeline, not the MS.

I was wondering why you couldn't see the solid exhaust plume during/after the failure, this expains it - it was indeed a high altitude abort, complete with grid fins and fairing retros.

Just at the point of the start of the deflagration, you can see a darker cloud before the expanding LOX expands. Maybe some kerosene tank ruptured at booster separation (which may be a cause for or a consequence of the failure of course)

Please don't kid with this. Peoples lives were in serious danger. This is a huge setback for human spaceflight. Although the Russians had their fair share of problems with other spacecrafts the human Soyuz flights were quite safe.

So that puts the distance from Launch Site to Landing Site at around 260 miles.

Not necessarily.  The spacecraft performed abort and got the crew back on land alive.  Anomalies like this are what abort procedures and practices are made for.

SAR 1 hour into flight. Will take 1 hour 30 mins (total time) to reach the crew.

Now about half hour away from reaching crew. Roscosmos forming State Commision to investigate launch incident. They will not be holding a press conference.

Can we make this thread updates only please. There is a separate thread for the implications already started in the General Discussion section (may not be the right place, but I'm sure it will be moved if necessary).

CNN is finally covering the story in the US
Best quote heard during an inspection, "I was unaware that I was the only one who was aware."

"Crew out of capsule. SAR have reached landing site"
