Let's hope all the...I's (were) dotted!

Really?! Look closely at yours!  ;)

It doesn't matter that much in a post, but the irony is that on a rocket, such an error could cost LOV, making your meaning even that more salient!

Looks like you got me...congratulations.

The final shape isn't all that different - the leg tips have been extended and rounded like the cap/fairings.

It looks like a pretty significant shape change to my non-aerospace grade eye.  Old version seems "pointy" and the newer overall shape is much more "rounded".  IMHO.

The overall shape is the same; the new one just incorporates the end cap.

I wish SpaceX would write the core numbers more prominently and in something other than pale grey.

I think they did this for aesthetic reasons, big numbers may look good to enthusiasts, but they look ugly to normal people. Look around you, none of your widgets have its serial number displayed in big visible letters, they're all hidden somewhere in small fonts.

yes, but vehicles tend to have identifying numbers prominently displayed (cars, aircraft, etc).  Although Ill concede that might not be an apples to apples comparison as a VIN is not exactly prominent on a car but license plates/tail numbers are so you get my point.  Im not sure an F9 could be classified as a widget like a mouse or phone
Tried to tell you, we did.  Listen, you did not.  Now, screwed we all are.

Rockets cores aren't anonymous widgets that just blend into the background. They're some of the biggest and noisiest things around.

Also, I don't believe that most people would call, for example, the serial NCC-1701 painted on a certain starship in quite a conspicuous location and at a very readable size "ugly". ;-)

Can we please nip this "should have HUGE numbers" discussion in the bud, and discuss more relevant things about block 5?

Ship numbers are not written large because those on the ship need to know what ship they are on, they are written large so that people on OTHER ships can see what ship they are looking at.

Unmanned boosters are not self-aware enough to need to know the identities of other boosters sitting or flying nearby (although that may change in the future), so the only reason to have numbers on hardware is so workers can tell the difference between them - in which case they don't have to be that large or noticeable.

Which means the only reason we're talking about this is because WE in the public want to know the difference, but making it easy for the public to track stages is apparently NOT a concern that SpaceX has. And we all know this, so we should not complain about it.

Getting back to the topic at hand, what do we know about land legs 2.0 now that they are on a stage?
If we don't continuously lower the cost to access space, how are we ever going to afford to expand humanity out into space?

Most major things about it have been discussed at this stage, so itís understandable that people turn to smaller issues.

Shouldn't complain...? You must not be from around here... ;-)

It may not be a concern SpaceX has now, but things do change. Quite often after-- Wait for it....

Complaints.

You don't consider the markings on the first class of rocket boosters that will actually survive to accumulate long histories -- and, thus, stories, anthropomorphized personalities and even names (which is what the serials are really standing-in for), either formally or informally (e.g. "Sooty") -- to be relevant discussion? That goes against millennia of human culture and tradition.

But okay, I've said my piece.


So SpaceX must be pretty confident to have their logo in the center of the core, rather than being cramped towads the bottom. I guess the new core insulation must do a lot to prevent the frost and ice build up that would otherwise obscure it. I wonder if perhaps they're also using some sort of hydrophobic paint to keep the logo readable during propellant loading?

A better, full res comparison of block 4 and block 5 from the same angle on the same pad.

I really doubt that is some magic paint can prevent frosting. The reason to move the logo could be as simple as not enough space between the legs.

Or that they aren't going to be washing the boosters between uses so they wanted the logo on the section that ends up the cleanest after they have been flown and covered with soot.  I think they are willing to just accept that the logo will be covered up or obscured some by ice/frost during loading operations.  They are big enough now and established enough that they don't have to worry about people not knowing who they are or having the company's brand damaged by people making sophmoric jokes about the frost pattern making the rocket say sex (really "ceX").

Considering the Tesla lineup, it wouldn't surprise me if Musk moved the logo on purpose just so it would say that...

They don't.

We can indeed nip the numbers discussion in the bud ... as long as we all agree that yes, there should be big numbers but SpaceX will do what they want, not what we want.  LOL

Then we can just enjoy this new booster and not argue. (semi serious)

It's said many times in the link, but still; it's Block 2 from CRS-6 not 4

Nobody else has said it so... Another big reason to move the logo is the new black legs. Previously, the logo overwrapped the legs, so if the legs aren't getting painted, or painted with black coating, no logo there is feasible, hence it needed to be relocated. Excited to see if there is a big difference in the soon patters vs previous blocks. 🌿👀🌿

what do you guys make of this? it looks like some sort of stiffing piece attached to the outside of the main leg structure. is that metal or just more carbon fiber? are those rivets?

Sure look like rivets. Looks too small for trying to affect airflow.

So if they are rivets, then it must be a way to attached a metal piece to a composite one?

Seems way more than necessary if those are rivets. Not sure why attach metal structure there. Here is the image showing the metal attachment around the root of old legs. The outside of leg shows panel-like structure, while inside looks like a unibody carbon fiber structure. Nothing like those bumps at all.
