The Ars Technica story was edited based on an FAA ... tweet.

(Note: at 6 pm ET on Wednesday, the FAA issued the following statement).

"The SpaceX Starship mishap investigation remains open," the agency stated. "The FAA will not authorize another Starship launch until SpaceX implements the corrective actions identified during the mishap investigation and demonstrates compliance with all the regulatory requirements of the license modification process."

According to Musk Sep 6, 2023 · 1:30 AM UTC, "Starship is ready to launch, awaiting FAA license approval".

But an Other Place comment from u/space_rocket_builder here was

Aiming for launch readiness as early as next week and the launch as early as start of mid September. FAA process expected “soon” but we could still be a few weeks away.

I think they've asserted themself to be a good source, but I am not sure.

Another comment (someone else) asserted that the propellant farm has not been loaded yet, and that takes a lot of trucks.

 

High resolution satellite images taken on September 3rd captured SpaceX's new crew access arm for SLC-40 poking out of Hangar M.

Also an overhead picture of SLC-40,

SLC-40 is being prepared for the arrival of the tower segments ahead of stacking with a large crane being assembled, and there's also a hole in the roof of the hangar..?

I don't know whether to post these here or off the main page.

Jerry Pike Photo has some nice pictures on Instagram of booster return at Cape Canaveral. The rusty ASDS really gives an interesting "gritty space" feel to it. These are links to each image, but you can just click on the first and use the ">" arrow on the image to go to each in turn.

The, or one of the, most successful rockets ever? And people are taking pictures and videos of the launches anyway.

 

The Launch Pad @TLPN_Official 2:27 PM · Sep 3, 2023:

SpaceX will now be exclusively broadcasting on X

All upcoming live streams on other platforms have been removed and the SpaceX website has been update to only show X.

I did a search for "YouTube" site:spacex.com on Google. There were hits but the ones I checked were only because of Google's cached copies; the pages themselves no longer have references to YouTube (or LinkedIn or other platforms).

There are many old videos on YouTube. I don't know where to look on YouTube to see upcoming streams, and don't have an inventory of videos, so I can't check them.

 

About 5 1/2 minutes. It's impressive that he can actually manage to do it in microgravity and unassisted.

Great work by the @SpaceX team successfully launching 61 Falcon rocket missions this year!

If tomorrow’s mission goes well, we will exceed last year’s flight count.

SpaceX has delivered ~80% of all Earth payload mass to orbit in 2023. China is ~10% & rest of world other ~10%.

and

Aiming for 10 Falcon flights in a month by end of this year, then 12 per month next year

I can't really find full confirmation of that. I do find an Xmission from Gav Cornwell @SpaceOffshore Apr 20, 2023 · 10:54 AM UTC,

Fast boat Gladys S departed from Port Isabel this morning to support the SpaceX launch.

Still not exactly sure what role the vessel is playing but it's confirmed to be involved based on its AIS designation of 'Texas Launch' and the fact it has two Starlink dishes mounted...

And a bit later, with pictures,

A look at the Gladys S, which appears to have been supporting the SpaceX launch in some capacity offshore.

Spot the Starlink terminals!

Notice they filled in the heat tiles with some type of epoxy/clay instead of replacing these damaged tiles. Indicator Ship 25 probably isn't expected to survive reentry.

125-megapixel image link: https://www.easyzoom.com/imageaccess/ad67522c147c4746bc055c5a80704e55

But they look like regular tiles to me, just with adhesive smeared around messily. Marcus House, in his weekly update at 5:31, zooms in and says, "we can see that a few surrounding tiles were damaged during the process [of adding tiles to cover lifting points], but these were to be replaced soon after this shot was taken.". At 5:44 on, he explained and showed a worker using the suction cup device: one tile passed, one pulled off.

 

u/675longtail on Reddit summarized it:

It includes a Starship development timeline, starting with an orbital flight attempt in Q3 2023 but moving on to detail:

Q1 2024: First Starship launch with payload

Q3 2024: Successful recovery of the "Starship system"

Q3 2025: On-Orbit Propellant Storage System Preliminary Design Review

Q2 2026: Starship On-Orbit Servicing/Recovery/Docking Concept Review

Q2 2027: Crew Starship Ascent, Entry, and Landing Concept Review

Q4 2028: Starship LEO crewed space station Preliminary Design Review

And lots of other tasks too. (For example, I have no idea what "a human health countermeasure tech demonstration" might be.)

A Space Act agreement doesn't involve payments between NASA and the company. But it does involve NASA and the company agreeing to do specified space-related things, where NASA will

Provide access to requested NASA technical data, lessons learned, expertise support, services, facilities, equipment, and NASA-developed technologies, on a non-interference basis as resources permit.

and SpaceX will "Provide NASA with data regarding its progress towards the milestones", meet periodically, and provide equipment if required under agreed Technical Implementation Plans.

Zack Golden @CSI_Starbase (Nitter link) Sep 2, 2023 · 3:45 AM UTC has a multi-post speculation about Super Heavy testing at Boca Chica.

I am now 95% confident that SpaceX is in the process of building not one, but two Super Heavy Static Fire Test stands. One will be located near the Suborbital tank farm, and the other will be at the Massey's test site.

These test stands are essentially mini versions of the Orbital Launch Mount. There are a few major differences though:

  1. These stands will not have launch capability so they will be much simpler....
  1. Because of the location of these test stands, and severe limitations on space, the method of testing engines will have to be different than how its done on the OLM. [flame trenches]

Why?

  1. Well at some point, launches will become much more frequent. This means the OLM will be nearly always be busy preparing for the next launch....
  1. The Orbital Launch Mount, with its new Bidet system is limited to Static fire tests of less than 10 seconds. It is truly designed for Launching Full stacks, and not for long duration tests purely due to the volume of water stored in the tanks.
  1. The OLM is also believed to be limited to Static Fire tests with thrust values at or around 50%. This is a result of the design of the hold down clamps. Also, the skirt of the booster is likely not designed for the kind of forces it would experience if it was being held down at max thrust....

So if this speculation is true, what should we be on the lookout for?

  1. The areas where these will be located will either be built up to accommodate a flame trench, or they will soon begin excavating large holes into the ground for this purpose.
  1. The suborbital tank farm will likely need to be expanded in order to increase its LOX and CH4 storage capabilities. I believe SpaceX is already in the beginning stages of this massive renovation.
  1. CH4 storage tanks will need to be added to the Massey's test site. They will also need additional GSE equipment for filling Booster COPV's. This includes Helium storage, CO2 for the engine skirt purge system.
  1. There will likely also need to be additional water tanks installed for traditional deluge systems for both of these tests stands....

He says he'd do a video if he weren't already in the middle of two deep-dives.

u/Alvian_11 in The Other Place says that a "flame diverter/ramp" is different from a "flame trench" and that a flame diverter/ramp makes much more sense.

Zack Golden @CSI_Starbase (Nitter link) Aug 31, 2023 · 4:24 AM UTC states "They have been testing [tiles on ship 28] with a suction device to see if they would fall off. A large number of them failed the test."

4 years ago, Starhopper flew. YouTube video.

 

The lawsuit cited a June 2020 post on X, formerly known as Twitter, by Musk to his then 36 million followers that said: "U.S. law requires at least a green card to be hired at SpaceX, as rockets are advanced weapons technology."

The Justice Department also pointed to online posts from the company's billionaire owner Musk as example of "discriminatory public statements."

There aren't a lot of details.

The DoJ release is "Justice Department Sues SpaceX for Discriminating Against Asylees and Refugees in Hiring".

Because SpaceX works with certain goods, software, technology and technical data (referred to here as export-controlled items), SpaceX must comply with export control laws and regulations, including the International Traffic in Arms Regulations and the Export Administration Regulations. Under these regulations, asylees, refugees, lawful permanent residents, U.S. citizens and U.S. nationals working at U.S. companies can access export-controlled items without authorization from the U.S. government. Therefore, these laws do not require SpaceX to treat asylees and refugees differently than U.S. citizens or green card holders.

SpaceX hired only U.S. citizens and lawful permanent residents, from September 2018 to September 2020.... The lawsuit alleges that, from at least September 2018 to May 2022, SpaceX routinely discouraged asylees and refugees from applying and refused to hire or consider them.

SpaceX recruits and hires for a variety of positions, including welders, cooks, crane operators, baristas and dishwashers, as well as information technology specialists, software engineers, business analysts, rocket engineers and marketing professionals. The jobs at issue in the lawsuit are not limited to those that require advanced degrees.

DoJ asks those might have been affected to contact them. Effects might include being rejected, discouraged from applying, et cetera.

 

Um, just what it says on the tin. Article by Jeff Foust.

Berger's Law: "If a rocket is predicted to make its debut in Q4 of a calendar year, and that quarter is six or more months away, the launch will be delayed."

When Isaacman and SpaceX announced Polaris in February 2022, they scheduled the Polaris Dawn mission for as soon as the fourth quarter of 2022. However, by last October the launch slipped to at least March 2023, which the program attributed to readiness of the vehicle and training as well as the schedule of other Crew Dragon missions.

In a talk at a conference in February, Isaacman said he expected Polaris Dawn to launch this summer....

Isaacman, in the podcast interview, suggested the delays were linked to the development of a new spacesuit required for a spacewalk ...

Polaris Dawn is the first of three missions in a program that will culminate in the first crewed launch of Starship. That final mission is “pretty far out there,” Isaacman said, noting that SpaceX still had a lot of progress to make on Starship before flying people on it.

 

Not my pics, mind you. I'm just quoting the title.

Things are Port Canaveral that we don't see much of. I like that it was pointed out that Doug had 4 fairings onboard.

 

I debated posting this, because it's not near 100% about SpaceX. But it's over 50% about SpaceX and Starlink, I think, and it touches on the problem when a government depends on one private individual for several areas, especially when that individual starts to go strongly against government policy. It's pretty even handed, in my opinion.

 

The operative parts seem to be

U.S. Space Force’s Space Development Agency ... is building a layered network of satellites known as the Proliferated Warfighter Space Architecture. It includes a Transport Layer of interconnected communications satellites and a Tracking Layer of missile-detection and early-warning sensor satellites.

“The studies will examine connecting commercial or other existing LEO systems to the Proliferated Warfighter Space Architecture to provide further resiliency by quickly moving broadband data between edge and main networks worldwide,” SDA said.

"a total of $1.6 million to the three companies" is chickenfeed, but might lead to a better position in bidding for the transport layer, I suppose. SpaceX is already doing some project called Starshield for Space Force.

In The Other Place, there was discussion of what it means.

I don't think SpaceX is interested in bidding SDA constellation work anymore, the head of SDA said so in an interview a while ago. The issue seems to be that SDA requirements means SpaceX needs a special bus for them, and there's not enough volume to make this worthwhile for SpaceX.

Chris Prophet suggests, then, that SpaceX might not bid on the Transport Layer but offer Starlink 2.0. He also pointed out

Believe SpaceX will use a new encryption software for their Starshield satellites supplied by the Aerospace Corp. It's too big a coincidence they both use same name, i.e. Starshield, and first orbital test came just before SpaceX announced they would develop a complete constellation. Hence Starshield should give SpaceX intimate knowledge of this new encryption standard.

 

The length is 38:50. It's for a somewhat more general audience; the Summit channel says "Summit is an ecosystem that exists to connect and nourish global makers. We are committed to fostering experiences that bring people together to explore, play, gather and grow ... together." and similar BOMFOG.

I think there's nothing new for long-time SpaceX fans. He gave the "throw away the airplane on every flight" analogy. But I don't feel that I wasted 40 minutes. There were several nice short SpaceX videos on various topics. He also went over Musk's "algorithm", which Musk had done with Tim Dodd The Everyday Astronaut.

First principles approach to technology ("the algorithm")

  1. Make the requirements less dumb
  1. Delete the part or process step

Run steps 1 and 2 as many times as possible before going on to

  1. Optimize
  1. Accelerate. (You can always go faster than you thought.)
  1. Automate

Musk, in his interview with EA, had a better example with the battery cover on Tesla. Kiko had an anecdote about fairing recovery.

 

Capt. Jessica Rozzi-Ochs says, “Starlink has seamless transition from satellite to satellite, unlike the legacy system, which drops service while it looks for and tracks a new satellite. This was particularly impressive when we experienced heavy weather (20+ foot seas, hard rain, 40-50 knots of wind) and Starlink didn’t go down once.”

And general mentions of the convenience of having commo underway.
