Soyuz Booster Fails but ISS Crew is OK

[Paratus]

Apparently the second stage failed but the abort system worked. The crew came down on a ballistic profile and ground crews found them safe and sound.

That’s a pucker factor.

Also shows why capsules on top of rockets are better than gliders attaches to the sides.

Glad to hear the abort process worked!

Well that will put an end to Soyuz for a while. If I remember they were already investigating issues with the prior launch before this failure. The next launch I believe was supposed to be in December to the ISS.

Will this make my TSLA calls go up?

launch - trouble starts around 2:40

you can hear the russian english translator saying 'emergency failure of the booster' @ 3:30, i guess the nasa commentator just has the video feed?

instead of clean 4x booster separation, there's a bunch of debris

Well at least their fail safe worked as planned saving their lives.

I’ll be glad when we have a modern heavy lift launch platform. Kudos to the Russians for bringing the astronauts home safely.

Holy shit that's a major fuck up. Can't recall an a escape system being used on a manned spacecraft before?

Is that the new Soyuz?

After seeing SpaceX videos for a while now that one feels like it happened in the 50's. What are all the beeps? Sounds like they communicate by telegram or some morse code shit.

Hearing the words "failure of the booster" during a launch is never a good thing. Brings back memories of "major malfunction" during the Challenger launch.

I'm glad the SLS has a similar abort system.

Is what happens in Mother Russia when the lowest bidder is also the only bidder for their gov't jobs. All other potential bidders are taking dirt naps.

So video came out today of what the booster separation looked like. It was pretty bad.

The failure was caused by a bent pin that’s part of the booster separation sensor. During staging the core continues to accelerate while the boosters slow. The pin pops out as the rocket pulls away and signals the booster to fire a small top mounted thruster to push the booster away from the rocket. With the pin bent the thruster didn’t fire that and it smacked into the second stage triggering the abort.

Here’s what a nominal seperation looks like.

Russians are calling an assembly error.

Thats insane, i cant beleve they lived, must have been the ride of a lifetime.

When you think about how complex these things are, its kinda amazing that they work as often as they do. It takes some guts to sit in one of those things.

They seem to have more assembly errors now. The old guard is retiring and new ones are either not up to snuff or are leaving the country instead.
