Looks like SN10 also has small patch of tiles (#5!!!) on the inside of the bottom flaperon. Not in the airflow so interesting why there...

@geoffc What does "Baikanour needs 53 degrees." mean?

@uhoh ISS is in an odd inclination. It is not great for the US and not perfect for the Russians to launch to. For Soyuz to reach the ISS and not take a huge payload hit, the orbital inclination was set at 53 degrees. The Shuttle took a big hit, launchin from 28 I think degrees. But it had a large enough payload to be possible and still work.

This one sort of discusses the issue.

@geoffc it's called a "detente orbit"?

Not sure.

it's a joke!

I think it's mostly solved in my comments now; anybody want a few math SE rep points?

Why are the top of the StarShips so bluish?

@peterh-ReinstateMonica The body is mostly rings. So unroll a SS roll, cut at 9m and weld the ends. The nose cones, are made of pressed SS, welded together. I THINK it is just because of the 'grain' of the material. But I am a bit colouor blind so I do not see it.

"What is this rock in my office? Throw it away, I said I want clean desk."

"But Mr. President, this is a rock from the Moon."

"Prior to the Starship SN8 test launch in December 2020, SpaceX sought a waiver to exceed the maximum public risk allowed by federal safety regulations.

After the FAA denied the request, SpaceX proceeded with the flight. As a result of this non-compliance, the FAA required SpaceX to conduct an investigation of the incident. All testing that could affect public safety at the Boca Chica, Texas, launch site was suspended until the investigation was completed and the FM approved the company's corrective actions to protect public safety. The corrective actions arising from the SN8 incident are incorporated into the SN9 launch license."

Looks like they are taking a shot at SN9 today. Flaps are untied, which is a good sign.

Pad is apparently cleared. Still need to load up the fuel/oxy, which will be very obvious.

Good live stream:

@geoffc Yeah!

It happens between "propellant loading", what is happening now, and launch.

Some kind of a loud noise, like a vent...

Why the engine has to be chilled? It will be soon thousands K hot.

You don't want to suddenly shock the system with freezing liquid fuels.

@PearsonArtPhoto Thanks! Do we have some "progress bar" on the "propellant loading"?

It was fully loaded, and seems likely to be detanking to some extent.

I bet they will reload it soon, and try maybe in an hour.

Uhmm... nooo....

How do you know it is some detanking? I see only white cloud at the bottom.

Just the sound that was heard. It's a guess, but...

Actually guesses say 25 minutes or so is likely.

What is the cloud on the top tank?

As if some fuel had been exhausted

OMG, we are in "engine chill"!!!!

Seems likely to be in the next 10 minutes or so.

Yeah! Another live stream has a countdown

T-2:40 from SpaceX stream

Background sound like filling a pressurized container

LAUNCH!!!

Wow, that's a strange sound...\

It would be good to see the height

Would be nice.

And flight! And we got us some Innsbruker!

Nothing I saw that looks bad...

Down to one engine.

Bets on successful landing?

I am votin Yes!

I too

I give it about 50%.

50% is probably the best bet.

Hovering at 10K altitude.

Bellyflop!

100,000 lb belly flop.

Or more...

Curious... How many of these have happened before? MOAB out of a C-130 maybe?

Probably 150 tons or more.

Continuing the point of "Don't piss off Elon Musk" He can land an orbital class booster on your house. Or an even bigger orbital class upper stage!

But not get the FAA approval to do so...

Nose seems deeper as last time, is it normal?

wow, lands

Nothing iis normal about this...

Boom!

At tthat point, he moves to his volcano lair and uses his laser.

Baaaaaaaadddddddd..........

It was closer last time.

Not quite! Flip was not quite!

"Gotta work on that landing a bit"

Understatement of the day.

So the engines restarted. They flipped, looked like too much to me...

Bets on damage on SN10?

But they arrived too fast, again

This has me worried more and more.

I think there's a fundamental problem with the landing, the fuel sloshing around so much at the end...

They have now pressurized header tank!

I don't think that solves the problem...

I too not. If there is pressure in the tank, the liquid inside still can go where it wants to.

The problem is then an air pocket can go where it isn't supposed to go.

So it changes it from a void to an air pocket, but I think that's almost as bad.

AFaik it is pressurized by helium

SN9 was.

NSF stream is suggesting (based on Scott Manley feed) second engine failed to start and something blew out. So engine restart issue.

Raptors are still very young, in terms of numbers built and flight time.

That's my thoughts on the last one. Holds pretty true for this one, but a bit worse...

I seems as if there would be much lesser fire today.

Maybe the CH4 tank was already empty?

Nah, the header is just for landing.

They probably didn't leave as much fuel in the rocket.

Rewatching the SpaceX feed, which is awesome, you see both engines begin to ignite, second one fails to stay lit and had a fire at the base.

There was rocket, there is no rocket. Hard to see, how quickly is more $ burned than I and my whole family will see in our entire lives

@geoffc Then it is a different problem?

Who knows yet?

"Looks like" to those of us with ZERO access to data other than camera feed.

I make no claims of certainty at all.

That is not so bad. Also falcon9s had so many "hard landings" that even videos could be compiled from them

True enough. Great video too!

25 million views already. That is hilarious.

I think good estimations with "looks like" are not so bad. We are not expected to give legally valid diagnosis

It's obviously at least a little bit different of a problem.

Yes, I've seen it. Speaker said, "we start the 2 engines again" or so, but clearly only 1 was started. The other gave only some flame

NSF had like 6 cameras and they have bee replayinig the various feeds.

Great video

Why the other engine did not start?

I read that the second engine destroyed on restart

Something flew off it. Important to know what broke.

Hope we get told.

What flew off, burned.

Hard to think any different than fuel.
