Unrolled tweet thread at threadreaderapp.com by Ryan Hansen Space @RyanHansenSpace. It’s a look at the details of the steel plate parts and assembly under the Orbital Launch Mount.

Much lifting and lowering and all sorts of craney stuff, but it’s believed that all the manifolds are in place by now. A nice Imgur picture of a manifold being craned.

New comment from /u/santacfan on Reddit:

Starbase live-

11:56pm- 2nd manifold is lifted off it’s stand (Who needs sleep anyways)

12:12am- Manifold is going up after some weight was added to balance the load

12:14:40am- Starts to swing over

12:18am- Lowering. This should go to the left of the plate installed earlier

12:23am- Trying to get it aligned

12:25am- Starting to bring it in closer to the OLM

12:31am- Lowered a bit more. (Looks like they’re at the 10ft mark where they paused for quite a while earlier. So I’m off to bed)

12:45am- Lowered into place.

1:21am- Raised again

1:50am- B10 turns into Massey’s

2:01am- Manifold is lowered again

2:20am- Manifold go up, Basket go down

2:25am- Manifold goes down

2:36am- Basket goes up

2:59am- Basket goes down

3:35am- Small crane swings what may have been the 3rd manifold into place under the OLM

3:51am- Grover moves a piece of small diameter pipe over to the left side of the OLM where the excavators are working

5:30am- LR11000 is disconnected from the manifold section

8:10am- Day shift off to a slow start

9:25am- White pipe is lifted by a small crane over by the berm. RGV’s pictures show that they might be running a new water line from the current vertical tank over to the OLM.

9:32am- LR11000 lifts the counterweight that was used to keep the last manifold level during the lift

11:04am- Basket goes up

11:21am- Retaining wall goes up where they’ve been excavating

11:24am- Basket goes down

11:36am- 2 workers carry a plastic pipe over to the pit being dug by the long reach excavator (if it’s metal, enter those guys in a body building competition)

11:55am- 2 dump truck loads of gravel dumped on the other side of the excavator

12:00pm- Nic is leaving NSF

12:53pm- Basket goes up

1:06pm- Basket goes down

1:24pm- Grover lifts a couple pieces of metal off of the top of the OLM

1:40pm- LR11000 moves another counterweight away from the OLM

2:11pm- LR11000 lifts another counterweight

2:17pm- Small crane lifts a piece of metal out of the excavation pit

2:53pm- In todays adventure of what’s stuck at Starbase. We have a small bulldozer hanging off the side of a low boy trailer.

2:53:54- Random kid says hi

2:58pm- The excavator wins again. Bulldozer is on the trailer.

3:34pm- Grover moves what looks like a long straight piece of rebar over to the cryo pit area

3:49pm- Grover lifts a triangular piece of metal to the top of the OLM.

4:13pm- Grover lifts another triangular piece of metal to the top of the OLM.

4:30pm- Grover lifts more rebar over for the cryo pit lid

4:50pm- Basket goes up (to the door on the side of the OLM)

5:02pm- Rocket cows hack the stream

5:03pm- Basket goes down

5:37pm- Basket goes up

5:44pm- Basket goes down

6:32pm- LR11000 picks up a deluge pipe

6:51pm- Grover swings out of the way

6:57pm- LR11000 Starts swinging deluge pipe over. Straight pipe with a curve on the end closest to the OLM.

6:59pm- Starts lowering pipe to the back left side OLM

7:47pm- Small crane lifts a short piece of pipe next to the bigger piece the LR11000 lifted over

7:51pm- Short piece swung back away

9:00pm- Looks like some work on the lid for the cryo pipe vault. Some people going in and out of the ring around the OLM. They’re hiding what we really want to see behind the tarps though.

9:15pm- LR11000 moves to pick up Y pipe

9:41pm- Lifting straps connected to the crane

9:56pm- Y pipe lifted

9:58pm- Swung around the OLM

10:06pm- Lowered to just above the OLM

10:08pm- Guide rope got stuck on smaller crane. Had to go back up.

10:09pm- Going back down

10:12pm- Sat on the ground right outside the pit.

10:14pm- Lifted Up slightly and rotated

10:15pm- Lowered into the pit

10:25pm- For those wanting to keep track, In Ryan’s renders, we’ve seen the bottom pipe that goes to the middle manifold and the Y section that goes over it lifted in so far. There should be 2 short pieces next to connect the Y to the other 2 manifolds.

(This gets synced)

Should we now be creating thread #47?

“SpaceX launched the most powerful rocket ever built. Its impact is still felt in this Texas community”, a CNN article dated Friday, 7 July 2023.

Musk has repeatedly said he’d like to try to launch Starship again as soon as this summer, but the FAA said in a statement to CNN that SpaceX has yet to take public safety actions or submit a mishap report with corrective actions for FAA review and approval.

Thread 47

#To repeat, new pinned thread:

Thread 47

As @clothes on lemmy.world pointed out: for some reason, via lemmy.world, this 46B thread is still pinned and there’s no sign of 47.

SpaceX @SpaceX on Twitter

Ship 25 completes a six-engine static fire test at Starbase in Texas

11 seconds. In the audio, only a little bit of HONK at the end.

Someone pointed out that the flames start out as a triangle, but then switch rotated 60 degrees when the vacuum engines start - V to ^.

A comment in The Other Place mentioned that it looks like a little spalled concrete at 4 seconds in.

In a later tweet, Musk called it a “Key milestone completed for flight 2”.

Ship 25 completed a flight-like chill and spin of the Raptor engine pumps, stopping just before engine ignition. As a result of the test, cryogenic liquid oxygen formed a visible cloud beneath the ship. This checked out vital systems in advance of the upcoming static fire.

RGV Sneak Peek shows some nice shots of the steel plates, as well as the pour under the OLM. Looks like a lot more concrete is needed though, wonder when that’ll happen.

The steel plates look ready for transport, so I bet this next pour will be soon — it seems to be the main hold up.

This is the finest FAQ in the fediverse. I come back to it, just to appreciate just how much data you fit in it, so easily accessible and concise for the experienced and inexperienced alike. It makes up for so many poorly written, ugly, inhuman FAQs across the years.

More pour info, this time from tweets from Zack Golden @CSI_Starbase. The truck counts basically match those from @LettuceTurnipTheBeet@lemm.ee’s post earlier.

SpaceX has received their final load of concrete for today’s Orbital Launch Mount foundation work. Here are the totals after the 15.3 hour marathon:

June 25th - 132 Truck loads

July 3rd - 171 Truck loads

Total Volume = 2,302 m^3 = 3030 yd^3

Total Weight = 5,411 Tons

For reference, a Fully loaded Starship ~ 5,000 Tons

Note: There were 4 additional trucks that showed up but were turned back around without offloading.

Shoutout to agents @VickiCocks15 and @SpmtTracker for keeping track of all these.

Obviously this number is significantly greater than we predicted. For those who asked, that previous number was not considering the area in yellow, which were also completed today. This area is technically outside of the true foundation of the OLM

Looks like the Ship Quick-Disconnect is back!

Exciting stuff happening right now (See Starbase Live).

• Launch site movement with the SPMT that transported the steel plate for the water deluge system and the SPMT with the Jig!
• Jig is being moved into position and now a crane is being raised! Things are getting exciting this morning.
• At the same time S28 is getting a payload door.

edit: And here’s the latest RGV Flyover video, which is the flyover from last week. Interesting content, but already heavily out of date.
