I love all 5 pixels you included of the livestream

Watching via starlink in Braselton, GA. Starlink has been rock solid the past few months. This is icing on the cake 🎉

Thank you for this Analysis I really enjoy the back-and-forth from you two guys. This was incredible. There's so much teaching going on from two incredible teachers you make a great team clearly explaining complicated science of space.

I think the on-board video feed made the biggest difference for us causal observers to be able to visualise the journey in far greater detail.
Would be ideal if SpaceX provided a live global map as well, soon you can see the flight path in real time.

Thanks for the video..
But why the 144p video replay?

Kinda starting to think that opening that PEZ door, combined with all that venting, might have caused Starship to roll uncontrollably...

[Alexander_S]

I am always amazed at how much the Starship can withstand. In the first test flight, it spun uncontrollably through the atmosphere and didn't break up, and the same here, it can withstand very heavy loads for a very long time. I'm really looking forward to the 4th flight, and then I want to see two landings :) It will be great!

The way the second stage is heating up and the heat is wrapping around to the sides, it looks like the field of tiles may need to be broaden for added heat protection.
Also, just before heating up, it looks like some dark pieces ( not just ice) possibly tiles were coming off. I am not sure, but I think they use only an adhesive to attach those tiles so as to not puncher the steel . There might be an additional attachment they could use to avoid tile detachment . The shuttle had some problems with the tiles too that they had to contend with every time it landed .
I worked in my dad’s business for ten years of the nearly fifty years it was in existence.
We were located in Southern California producing thousands of different custom parts for many different industries including the air/space industries.

did youtube mess up the quality of your vid during upload? or were you two actually reviewing the playback in 240p/360p quality

Starship thrust to mass (T/M) ratio at liftoff is 1.45. Space Shuttle T/M at liftoff was 1.5. Saturn V T/M at liftoff was 1.2. Starship is about three times more massive at liftoff than the Space Shuttle, but it accelerates as quickly as the Shuttle. High acceleration during the vertical climb out reduces the gravity loss and allows the pitch over to occur at a higher altitude.

After this re-entry, I will never worry about another missing heat shield tile again.

[irrefudiate]

Okay, Falcon uses the hell out of control thrusters in combination with grid fins. Starship booster is much more massive and depends on grid fins. Also, Starship's "wings" can't possibly control the ship at that speed and altitude.

[johnruckman]

There was some mention of testing rotating Starship. Something they were thinking of doing on the trip to Mars to create some microgravity.
The fact that they couldn't stabilize Starship may indicate that the vector thrusters are too weak. Remember that thing about mass, velocity, etc?

[shaung]

Ship is most likely doing a hard splashdown for failure data so they have solid information on breakup patterns and debris fields to aid in defining exclusion zones for starship landings. They already have landing burn data from the early suborbital testing so they don't need that other than to validate the transition control from hypersonic to subsonic and then landing.

42:00 that one is actually from the April 20, 2023 launch. The headline, from the same guy on cbs, this time was "SpaceX launches Super Heavy-Starship rocket on third test flight"
The media reception on ift-3 was much more positive (as it should be). Not perfect, but I watched a lot of different stuff and it was treated surprisingly decently.

[privateerburrows]

The grid-fin control PID needs a considerable augmentation of second-derivative gain.

[LG-cttw]

Those chunks are hexagonal and in nested groups, they are tiles not ice. They are black not shaded ether because you can see the white ice ones among them.

[knowledgeisgood]

10:15 The booster HAS header tanks. The LOX is at the bottom and the LCH4 is the transfer tube (which passes through the LOX one).

[erikmoore]

Dr. Know it all is always too nice to tell this particular guest to not talk over him so often. Lol.

Great analysis- nice chat - happy St Patrick's Day from Kilkenny
