The catch arms grab pins on either side of the booster or ship. Those pins can be moved to a lower location to accommodate a longer vehicle. 

If at some time this relocation poses a problem (balance, etc) they can take the top off the tower and add another segment; they were built using modules. 

And the arms catch only the booster or the starship not both still attached. So I think the height of the tower is not a real issue at the moment.

The arms need to reach high enough to stack a Starship atop the Booster before launch. We already know there will be a longer Starship, be it Starship v2 or the Artemis Depot.

 

Pre-launxh testing for Flight 3 has begun,

 

there were a lot of well known improvements between test flight 1 and test flight 2. I am seeing less upgrades between the vehicles used for 2 compared to 3. Is there much information about there about what is new?

I haven't seen much, but I would expect there would be some improvements inside the tanks that we won't see.

I didn't realize this, but apparently this ship has a payload door.

As mentioned by bguy_1986, the payload bay and internal changes. Also the that Starship will have a major upgrade to Starship 2 after the nexr few launches. Major structural changes, so why upgrade an evolutionary dead end? Rumors of changes to the fins, etc, and a statement from Musk the dry mass would be going down at the same time the tanks will be getting larger. 

Speculation: this seems to make sense if SpaceX will be using the new HFS* steel alloy Cybertruck is introducing. It took CT's door panels down from 3 mm to 1.8 mm without sacrificing strength.

Testing over for the day, and two new tanks and a Starship launch tower segment has departed KSC for Starbase

 

 

Do we know what happened? Looked like a lot of venting when it should have been filling, was something broken?

They did a lot of work on the tank farm to fuel the rocket. Maybe it was something with that. Although they did have a drone checking out a section of the booster. 

Ship: single-engine static fire, looked like a previous test of a de-orbit burn.

Booster: long static fire, about 10 seconds.

If all the data looks good, and the regulatory gods smile on them, Flight 3 could be really close.

Next steps for Starship, and Musk will be giving a SpaceX company talk which will be webcast on X. 

Long post, so full text at bottom

Quote

Overnight Ship 30 rolled to SpaceX's Masseys test site, joining Booster 12 for cryoproofing

 

As it stands:


Booster 10/Ship 28 - tested through to Static Fires. Next up, flight configuration work (likely at prod site), then rollout for integrated stack pre-launch testing.

 

Booster 11/Ship 29 - Cryoproofed, receiving engines, then ready for Static Fire testing.

 

Booster 12/Ship 30 - At Masseys for cryoproof testing.

 

Are you all ready for 2024? 😎

From the recent SpaceX All Hands company meeting,

The causes of the Fight 2 failures are now known. The Booster flip was too rapid, and Ship's liquid oxygen venting caused a fire.  They know how to fix both.

The upcoming Flight 3 will  attempt to achieve orbit, perform an orbital refueling system test, and test a Starlink satellite deployment door. The new Starlink satellites will be much more powerful, further speeding up the network.

After Flight 3, a second Starship launch complex will be built at Starbase. A tower segment is already on the way by barge from the Kennedy Space Center SpaceX Operations Area in Florida.

The new tower will be taller to accommodate an increase in size of Starship V3, the upcoming Starship V2 being a transition vehicle.

Booster + Ship height,

Starship V1: 121 m

Starship V3: up to 150 m

After Tower 2 is complete, Tower 1 will be upgraded. 

------

Starship launch complexes in Florida are already in the approval process (LC-49), LC-39a being partially built. Wouldn't be surprised to see some at Vandenberg Space Force Base in California, probably at SLC-6 (aka Slick Six)

big changes in the pipeline. It's already an insane size, when it's 150m it'll be evenmore so.

The fast pace helps the 'failing forward' process, which is why they have moved so far ahead with reusability. Ditto for Tesla EV development.

Many people don't seem to get this. Those folks need to read John C. Maxwell's book.

New Starship tower segments at KSC, to be shipped to Starbase where a second launch site is being prepared. Needed for redundancy and an increased flight rate. Tower will also be taller to accommodate the larger Starship V2 & V3. The existing Tower will also be stretched.

    • Bluesky COO warns social media regulations could destroy competition from small startups by Paul Hill Fears that increasing government control of social media risks regulatory capture by the biggest social media firms were raised again recently. Bluesky’s chief operating officer said in an interview that social media bans for children and tighter regulations for social media firms risk creating a world where there are only a few social media platforms run by companies with the deepest pockets. Regulations on social media firms have been very lax since they appeared for mainstream users in the 2000’s. This gave Meta, Snapchat, and Google time to build up their user bases and get entrenched, with Meta being the most successful. Now that Meta has succeeded, it has been attempting regulatory capture. By pushing for more regulations of social media, Meta hopes to make it more difficult for rivals to challenge it. For its part, it doesn’t need to worry about the cost of regulation because it has a lot of money to spend, whereas startups do not. Speaking to CNBC, Rose Wang, Bluesky’s chief operating officer, said: “I support the protection and the safety of youth, the question that we have then is at what cost, because essentially what I’m scared of is in the long term, we’re headed to a world where there’s about three to five platforms, and extreme heavy regulation of those platforms, and basically the whole compliance teams of these platforms are 10 times the size of our entire team. So, basically, we’re living in a world where it’s almost impossible for smaller entrants to come in and build healthier spaces. These platforms have led to a place where the bottom line is the thing that drives what they do... so I understand why governments have to step in and regulate, because the platforms have done nothing right.” She said that while she is not against regulation, there needs to be more channels between the small to mid-sized players and regulators to help protect them. She says that big tech players, on the other hand, “who we know are circumventing regulation,” need to be regulated. Essentially, the Bluesky position is one of nuance, rather than absolutes. While Bluesky’s proposal may preserve competition in the social media space, it still doesn’t address the massive privacy implications these age verification measures introduce, such as handing over sensitive identity documents to access age-gated content.

    • it dosnt support onprem exchange. it dosnt support mapi-calls. the views are all worse/limited. its slower. it cant see public folder calendars. we already have webmail. the list of other missing features is pretty huge but i only see it when customers call to say their email isnt working, and 9/10 times its cause they accidentality changed to outlooknew(new). Hold the line everyone!
    • yeah, this looks beautiful. Damn this winter's going to be great.
