Velocity never started going up post-stage-separation.

~15 minutes until planned launch.

Was having trouble parsing what the final partial transmission was.

Guy on the Dart Livestream: You don't want to blow up an asteroid. The pieces will still hit earth. You don't want to miss a thing. I refuse to believe this wasn't an overt reference to that awful scene in Armageddon with the animal crackers.

Must just be heavily time-delayed. The captions are clearly human-generated and showing up before the words. If youtube does live human-generated captions it could be just a minute or two delayed, though.

Was this filmed yesterday? All the captions are clearly finished already.

Is a "failed range" a range violation or a sensor value out-of-range? edit: In this case, it was a plane. Ambiguous words in dynamic environments worry me. But I guess they have been chugging along with "LOS" having two different meanings relating to comms and understanding based on context for a while.

Falcon 9 flights are officially boring enough that there were no posts in this thread from launch to landing.

Are we sure the previous footage was burned? Hardened storage of telemetry and footage is far from impossible.

That thing is sitting on the absolute edge of the pad.

Hope they get all the failure data they need from that... 'footage'.

Never make critical plans that depend on government employees on a Monday. Source: was a government employee.

My point is that these similar systems have a rather low expected landing velocity. There's no reason to think the goal shouldn't be right around zero, depending on good software. Falcon plops down on a gyrating barge.

If the plan to snatch one of these out of the air by the grid fins is real, then those anemic looking legs ought to be enough. That was a pretty high landing velocity.

Limited cameras on this flight.

Last landing failure happened one day short of a year ago. Starlink 4.

Suggests there was ballast on this one. Maybe more fuel.

Stepping through the frames, I was parsing this frame wrong. That's a silhouette of a stopped engine, not a profile of the bell of a running engine. There is fire where there should not be fire. And no fire where there should be fire.

Could be insulation. Could be harmless. A full turbopump is probably dense enough to fall faster than the stainless steel balloon it came off of.

Are youtube notifications broken for anyone else? I seem to get notified of Spacex streams maybe 40% of the time. Less reliable than the raptors.

Hi ExtremeSquared, I know it has been over a year but did this change provide any positive outcome for you with regards to contract lengths? Sorry... never really got back to it. I decided that my expectation that I save a few % on deltaV to do a standard max-efficiency low-speed Hohmann transfer to Plock was unreasonable, and therefore my complaint was fundamentally flawed. At no point were the contract lengths technically unreasonable.

I wonder if they will attempt fairing capture in the poor weather conditions. I guess they'll mention it at t+39 if so.

Make it a spike, then. Nobody likes it when their tent blows away.

I just assumed anchors pulled out based on the fact there are pictures floating around with rolls of stainless steel chained to it "holding it down".

Pictures of the failed sn9 stand with weights attached make me think that they knew the ground anchors could fail and had no better option, which in turn makes me think the foundation is fundamentally inadequate and will require a full reconstruction of the high bay. It's really not that heavy when empty though... Anyway, this is all speculation.
