I don't care for the looks of the hot staging ring. Makes it look like a potential point of failure. Other than that, yeah. The chines look like they belong there and it's typical that a vehicle going through rapid design iterations looks more refined with every new version.

As I keep saying. One of the most distinctive things about Starship is its looks. Especially compared to the Space Shuttle which, at least when sitting on the launch pad. Looked like a bunch of random stuff glued together.

I don't think so, I think ground testing is basically done. They put a test article through its paces at Massey's. They had to have confirmed it's strength because they aren't going to risk a full stack until they're confident that it can hold up to both propellant weight and liftoff forces. It would be too costly if it failed on the pad. I think at most we'll see a LN2/LOX load test prior to the WDR.

The other thing is that Im sure they have a really good set of data from all the testing they have done on the booster and starship. IMO it would be much easier to add that hot staging ring that it would seem.

-No internal pressure considerations or cryo considerations.
-No need to make it thin to make room for anything
-It is only structural, no other uses. The heat shield for the booster is the only consideration beyond "it has to hold up the starship"

All it really has to be is a spacer between the mount points on the booster and the mount points on starship. Much easier than trying to add a tank or something.

Add in a bit of mechanical testing and I could see them being really confident in their evaluation and estimates.

All bets are off if they want to kill time waiting for the license though.

I found a pic of them getting set up for testing with the can crusher.

Good points. They have all the data from the unpressurized ship skirt and the top of the booster. They also have the data from the unpressurized booster aft section that has to take the weight of the full stack plus the thrust of the 20 outer engines. I think they're good to go.

they already tested the hot staging ring on the can crusher.
It will experience more load during sep than anything it will see in launch or wet dress or even max Q I believe.

I remember when they abandoned carbon fiber and got to work in stainless steel. Those first few attempts left me saying, “really? Looks like a poorly made Buck Rogers prop.”

It'd be really impressive if they actually hit anything close to that date. At the time of the first launch, I think most people figured it'd be a miracle if they had a second launch at all before the end of this year.

Know the feeling. I am 5hrs away. Went for the 5/19 launch. Got there at 8pm. Stayed up all night, only to have it scrubbed the last minute or so of the countdown. But while I missed seeing the launch - it was fun talking to people from all over the world who had come to watch it. I do not keep track of all the YouTube personalities, but a handful were there and other people enjoyed talking with them as well. I met one family that few in from Germany, and a decent sized group of Canadians. A number more that came for the East coast...

After the abort - I went back to my Jeep and took a 3hr (or so) nap as the parking lot cleared out.
