Control problems on the Ship?

11:15 attitude control not looking so good

And something glowing on the skirt at ship SECO

Attitude seems to have stabilized?

Noticed this as well. Also there seemed to be some sort of gas venting or flame coming from the ceiling of the engine bay about halfway through the ascent burn

Definitely not built in a cleanroom!

Looks like a snowglobe in there.

Payload door did not open all the way; the door will be closed back up. The dummy Starlinks will not be deployed.

This shows that not everything's gonna work perfectly as one may think.

Yeah, from what I remember they only tested it on flight 3 before this, and even then it looked to be struggling to open a little bit

Does anyone else think that the attitude control has been very sluggish on this flight? it seems to meander quite a bit.

After a long career in design engineering this comment made me LOL. So many great possible responses to chose from.

Still, that's another bit of data the engineers got; they can use that to figure out how to make the payload door open all the way.

Have they lost video from Ship? Normally, we would see video from it showing the fins and other things. I wonder if the attitude control failed and that's killing the feeds.

Seems to be getting worse - it's pitching what looks like +/- 80 degrees or so.

Ke8ort · « **Reply #34 on:** 05/28/2025 12:07 am »

Ship is whipping around quite a bit based off the view from the cams

Looks like frozen LOX flakes swirling around in gas flow. Not a good sign.

What are we even looking at? What is white cloudy stuff anyway?

StraumliBlight · « **Reply #37 on:** 05/28/2025 12:10 am »

Can they pull out of the slow spin using the flaps?

I'm presuming a combination of clouds below and gas being expelled through the tank leak.

mikegi · « **Reply #39 on:** 05/28/2025 12:11 am »

Yep, they confirmed Ship is out of control now. It's a shame we aren't going to see a test of the heatshield changes. That's the critical step to a reusable LEO stage.
