Launch News Soyuz MS-10 Orbit Failure (developing story)

[rodion_herrera]

The Soyuz MS-10 launch experienced a booster (2nd stage didn't ignite or partial ignition I presume?) failure and did a ballistic trajectory. As of this writing the capsule is expecting to reenter and land in Siberia.

Bad news for the astronauts, such a ballistic reentry isn't a nice experience.

But at least chances are high to survive it.

SAR is in contact with the crew.

Confirmed that they have landed.

HOLY CRAP!!!
It seems the core went boom... :blink:

That orange flame is not normal. Seems like the 2nd stage (the long core) had issues even before separation of the 1st boosters. And it's definitely not supposed to "cough" like that.

Also, note that the stack was teetering/swaying a little prior to 1st stage sep.

Looks more like something went wrong during booster separation, except the amount of debris after the separation, all looks correct. There is always a lot of interaction between the many exhaust jets of the Soyuz.

SoyuzMS10: Recovery crews have reached the Soyuz MS-10 spacecraft; Ovchinin and Hague are now out of the descent capsule and are reported to be in good shape; they will be flown back to Moscow, according to NASA commentator Brandi Dean

What I saw on another thread (which may or may not be true), it was a problem with going from 70% - 100% on the centre stage.

 

[Urwumpe]

Could it be that a booster had a dry turbo-pump and separated earlier? These puffs in the exhaust trail look strange and it seems like something separated already a second before usual staging.

 

[tl8]

So medium term is probably ok with commercial crew next year and it is probably possible to to bring those flights forward a few months by throwing more resources at the problem.

The next Soyuz is due to go in late Dec, but that seems unlikely now.

Soyuz MS-10 moment of failure - YouTube

This one is showing the onboard at the time of the "anomaly"... scary jolt (it loops as the signal was lost).

Not too scary considering how staging usually looks like.

In this video you can also see a small jolt during staging at about 2:30:

Just compare the current launch to this one from the outside:

It really doesn't look too strange right until staging. What is odd is the huge cloud at staging and the additional debris afterwards.

But those accelerations are +/- vertical, this one was sideways.

Can't tell for sure from the short frame there left. It rather looks like forward to me, especially if you focus on the plush animals in the top left corner.

"According to preliminary data, the Soyuz accident occurred because one of the four first stage units hit the second stage and pressure dropped, the source reported."

Anyone else confirm this from another source?
