Fish and Wildlife's comments were published yesterday. I gather that the document was deleted from the original location, but as I recall, it was pretty much copied and pasted into the body of the final FAA determination WRITTEN RE-EVALUATION OF THE 2022 FINAL PROGRAMMATIC ENVIRONMENTAL ASSESSMENT FOR THE SPACEX STARSHIP/SUPER HEAVY LAUNCH VEHICLE PROGRAM AT THE BOCA CHICA LAUNCH SITE IN CAMERON COUNTY, TEXAS. I remember the bit about "Per the table above, an average summertime thunderstorm at Boca Chica would deposit more water over the landscape than any single or all combined activations of the deluge system".

>The Hyperbola-2 methane-liquid oxygen reusable verification stage rose to a height of 178 meters during its 51-second flight. It performed a powered descent and soft landing, supported by four landing legs. The 3.35-meter-diameter, 17m-long test stage is powered by a variable thrust Focus-1 engine. >The vertical takeoff, vertical landing test marks progress towards a reusable medium-lift rocket to debut in 2025. It is also the latest marker in Chinese efforts to emulate the success of SpaceX and its Falcon 9 rocket.

Tory Bruno spoke. >“If I were buying a space business, I’d go look at ULA,” Bruno said. “It’s already had all the hard work done through the transformation. You’re not buying a Victorian with bad plumbing. It’s all been done. You’re coming in at the end of the remodel, so you can focus on your future." I have some skepticism.

>In an Oct. 9 letter to the FAA and Congress seen by SpaceNews, SpaceX principal engineer David Goldstein said the report relied on “deeply flawed analysis” based on assumptions, guesswork, and outdated studies. The article contains details. >In 2021, the FAA commissioned the Aerospace Corp., a federally funded nonprofit focused on space, to provide a technical assessment of the rise of LEO constellations and the risks posed to aviation and people on the ground by unplanned and controlled reentries of these satellites and the upper stages that launch them. Someone from Aerospace mentioned the difficulties in such an estimate, and Goldstein's letter points out more problems.
At about 1 p.m. Central, >ISS: In the last few minutes, MCC-Houston asked the ISS crew to go to the cupola and look for any signs of "flakes" toward the aft of station; Jasmin Moghbeli reported "yeah, there's a leak coming from the radiator on MLM;" the MLM is the Russian Nauka multi-purpose lab module

Good analysis, from all I've heard. >Anyone who keeps track of Elon Musk knows the world's richest man has a penchant for setting aspirational schedules for his companies....So, if you have an opportunity to interview him, why spend time asking Musk to prognosticate when one of his companies will do something years in the future? and >SpaceX's brilliant engineers certainly have creative ideas and novel plans to get Starship to the Red Planet, so why not ask Musk about them when you have him for a rare hourlong one-on-one conversation? It's the how that is most interesting now, not the when or why, especially for an audience interested enough to tune in at the IAC. and >But Mowry's questions missed the mark at a time when the Starship program is at a critical point, and he didn't probe with follow-up questions to tease out more insightful answers. The whole article is worth a read, really.

Well, *that* was an unimpressed review from Eric Berger, though Bob Smith has stuff to be unimpressed about. Eric also mentions Glassdoor reviews, an ex-employee group letter, and anonymous citations of current and former employees. > the company's new chief executive will be Dave Limp, who stepped down as Amazon's vice president of devices and services last month.
Starlink @starlink Sep 23, 2023 · 9:29 PM UTC: >Starlink is available on all 7 continents, in over 60 countries and many more markets, connecting 2M+ active customers and counting with high-speed internet! >Thank you to all of our customers around the world 🛰️🌎❤️ → stories.starlink.com The significance is as u/Obvious_Parsley3238 pointed out: "250k last march, 1 mil last december, 1.5 mil in may, 2 mil now".

I'd seen the story about a spacecraft making a drug in microgravity and planning to land it in the US. >However, the recovery of Varda's capsule is on hold after the Federal Aviation Administration and the US Air Force recently declined to give Varda approval to land its spacecraft in a remote part of Utah. TechCrunch first reported the FAA turned down Varda's application for a commercial reentry license. >"Varda Space Industries launched its vehicle into space without a reentry license," an FAA spokesperson told Ars on Wednesday. "The FAA denied the Varda reentry license application on September 6 because the company did not demonstrate compliance with the regulatory requirements."

The FAA has repeated multiple times: there is no launch licence yet for a second launch. Since the FAA asked the Fish and Wildlife Service to look into the matter, I think it's highly unlikely that the FAA would issue the licence before FWS says it's O.K.
I don't know that there has been a definitive statement of the exact ending date. The Xeet summary provided included "The FWS has up to 135 days to submit the final biological opinion to the FAA (Started in August)." If it's 4 months including weekends and holidays, it could be up to December 1 to December 31ish. But it could be handled before then, or if the FAA agrees, the deadline could be extended, or maybe it's working days only. Also, the FAA would likely need time to digest it and issue its own ruling.
But there have been other reports that the FAA hopes to be done with it by October. So maybe they have inside knowledge.

I posted here about the FWS environmental re-assessment due to the booster bidet.
I don't have a transcription to hand and shouldn't take the time to do it myself. The image alone: https://nitter.net/pic/orig/media%2FF6VfGnVWYAAB5tv.jpg The FAA asked the Fish and Wildlife Service for "re-initiation of Endangered Species Act consultation" due to the booster bidet. FWS has 135 days to give a final biological opinion.

Just wanted to point out a glamor video of Starlink deployment.
SpaceX's social media people are really outdoing themselves lately. This video is, I think, the second one showing recent Starlink deployment. The mirrored surface reflected the second stage so well is stunning.

Eric Berger quoted a tweet from the FAA here, but it was in the form of an image. A text transcript was kindly provided by World Spills @WorldSpills here:
SpaceX conducted a test flight of the Starship/Super Heavy at Boca Chica, TX on April 20, 2023. As a result of that launch, SpaceX completed a mishap investigation with FAA oversight; this investigation analyzed the launch, mishap events, and corrective actions. Before it is authorized to conduct a second Starship/ Super Heavy launch, SpaceX must obtain a modified license from the FAA that addresses all safety, environmental, and other regulatory requirements. As part of that license application determination process, the FAA will review new environmental information, including changes related to the launch pad, as well as other proposed vehicle and flight modifications. The FAA will complete a Written Reevaluation (WR) to the 2022 Programmatic Environmental Assessment (PEA) evaluating the new environmental information, including Endangered Species Act consultation with the U.S. Fish and Wildlife Service. If the FAA determines through the WR process that the contents of the PEA do not remain valid in light of the changes proposed for Flight 2, additional environmental review will be required. Accordingly, the FAA has not authorized SpaceX's proposed Flight 2.
It was followed by untranscribed
The FAA will provide updates with notification of any license determination or results of additional environmental review.
I saw this somewhere on Xitter or The Other Place. I hadn't heard that there had been any sort of re-evaluation or more documents. The first document is dated 14 April 2023, so just before the first test, IFT-1: > WRITTEN RE‐EVALUATION OF THE 2022 FINAL PROGRAMMATIC ENVIRONMENTAL ASSESSMENT FOR THE SPACEX STARSHIP/SUPER HEAVY LAUNCH VEHICLE PROGRAM AT THE BOCA CHICA LAUNCH SITE IN CAMERON COUNTY, TEXAS >Starship/Super Heavy Vehicle Ocean Landings and Launch Pad Detonation Suppression System and following letters and documents are below it, dated as early as October 2022. 122 pages, oy vey, but a *lot* of repetition. I don't know enough to know whether there was anything significant, unless the FAA saying (paraphrasing) "these are some changes and considerations, but they don't have significant impact". There were changes expanding the landing zones, and more biological details, and lots more math about sound effects.
The first image, of Super Heavy + Starship at night reflecting the launch tower -- is astonishing.

An easier way to reach the app in Android is the Google Play store. It's named Austin 311 from City of Austin. Some negative reviews, though, like (20 Jan 2023) "You can't report when your trash doesn't get picked up - easily 99% of the reason I ever call 311" and (9 June 2022) "App sucks. The categories are very limited and hard to locate. I should be able to search on a keyword and your app suggests appropriate categories. Where do i report a malfunctioning pedestrian cross signal, for example. Very disappointing!"
I just checked out the Web page. That has a search capability (I don't see one in the app), both built in via a Search text box, and the browser's own facility (except there are not many items per page). I think I prefer it, even on my phone.
But the Android app at least has a map of recent reports, which is a nice feature; I don't see it in the web page. It also has one central place to enter the reporter's info; it looks like the Web page has it on each request.
It's an interview with Brian Fuchs, a climatologist with the National Drought Mitigation Center, which publishes the Drought Monitor map. He talks about the center itself, He talks about how they determine drought, considering lots of different factors and their impacts. There's a distinction between short-term and long-term drought. He compares the current situation with 2011, which was actually the peak of a long drought that lasted until 2015 or so.

Article by Jacek Krywko, 13 September 2023. No intro here, but a much older article says "a science and technology writer based in Warsaw, Poland. He covers space exploration and artificial intelligence research, and he has previously written for Ars about facial-recognition screening, teaching AI-assistants new languages, and AI in space.". WOW! I have no knowledge of the field, but it looks informative. As articles go, it's fairly long. It's about efforts to get "bioregenerative life-support systems", living life-support systems as needed for long space journeys and bases over yonder. The first efforts its lists were plant-based, BIOS (Soviet) and CELSS (US). >BIOS-3 experiments showed how much labor it took to operate this system. Results were bleak. Astronauts basically worked like full-time farmers just to keep it going.... There was very little control over what exactly the biological component was doing. Then MELiSSA was proposed and implemented. It is bacteria-based. The great advantage is that each bacteria species does about one thing, and responds immediately to conditions, so humans can have much much more control. But it was a huge project: >The project quickly grew into a gargantuan effort backed by 14 countries and over 50 institutes, universities, and companies. Then >In 2017, NASA founded the Center for Utilization of Biological Engineering in Space (CUBES), a conglomerate of federal agencies, industry, and academia, with the goal of building a demonstration biosystem for a future Mars colony.... >While MELiSSA was focused on fine-tuning the hardware and software and left biology intact, CUBES involves engineering all three to make them work seamlessly together. So bacteria-based, but now with genetic engineering. Also looking at producing more, like plastics or papers or more. It talks about one drawback of that approach: "The problem is that life, when pushed, sometimes fights back." The changes for more productions of nitrites or fatty acids or whatever are not adaptive for the organism, so it has an incentive to mutate back towards its original if that can breed faster. There's also discussion of multiple stages with more and more capability. And also discussion of funding. MELiSSA has continuing funding and is looking for a human prototype. CUBES has had some design work, "with, like, $15 million USD in five years". Anyway, well worth considering, and the comments are more valuable than in many comment sections. I did see fuzzyfuzzyfungus noting his own lay experience in existing bioreactors (amplifying a point above), specifically "the occasions when very, very unhappy science types announce that we'll be shutting down production because some undesired strain that's a lot less useful but a lot better at survival than the desired strain had snuck in and it was time to bleach out the tanks and sterilize everything to hell and back were just a thing that happened on occasion". Edit: other items mentioned in the comments: [A City on Mars: Can we settle space, should we settle space, and have we really thought this through?](https://www.amazon.com/City-Mars-settle-thought-through/dp/1984881728/ref=mp_s_a_1_fkmr0_2): upcoming book from the Weinersmiths.

This is related to @navi@lemmy.tespia.org's post about [SpaceX no longer taking losses to produce Starlink satellite antennas](https://lemmy.world/post/4995227). The article below refers to that one. ArsTechnica, in ["SpaceX projected 20 million Starlink users by 2022—it ended up with 1 million"](https://arstechnica.com/tech-policy/2023/09/spacex-projected-20-million-starlink-users-by-2022-it-ended-up-with-1-million/). It's based on a Wall Street Journal article, which seems like a bit of a hit piece. The headline claim is absurd, as some comments pointed out: the projection was in 2015! It also points out that skeptics had always said that Starlink would not do well in cities, which would be a more valid criticism if Musk and Starlink didn't point it out first. But there was this reported number: >Actual Starlink revenue for 2022 was $1.4 billion, up from $222 million in 2021, according to the report. The documents apparently didn't specify whether Starlink is profitable. It mentions numbers that Shotwell had previous provided and that may have been reported here. I'll add them to have more data in one place: >SpaceX President and COO Gwynne Shotwell said in February that Starlink is expected to turn a profit this year. While Starlink's specific profit or loss is unknown, the WSJ previously reported that SpaceX overall "eke[d] out a small profit in the first three months of [2023] after two annual losses." SpaceX's Q1 2023 numbers reportedly included a $55 million profit on $1.5 billion in revenue. The CNBC article had this, partially quoted in this ArsTechnica article, >The company last provided an update on its global Starlink user base in May, when it said it had about 1.5 million customers. Hofeller did not specify what that total is now but said Starlink is "well over" that 1.5 million mark. The figure includes both consumer and enterprise customers around the world ...

I got the impression from reading the few posts about it that it's going to start as a backup for the existing crew Dragon tower. Whether it could ever become Son of Mechazilla in the long run I don't know, and I doubt it. I suspect, though on no evidence other than prior practice and the 5-step algorithm, that SpaceX would rather debug the first model some before building a second.

This is a link to my separate story post: "(Reuters) US could advance SpaceX license as soon as October after rocket exploded in April", including a bit of interpretation.
www.reuters.com
>WASHINGTON, Sept 13 (Reuters) - The acting head of the Federal Aviation Administration said on Wednesday the agency could advance a launch license as early as next month for the SpaceX Starship rocket after a prior one exploded following a test launch in April. >"We're working well with them and have been in good discussions. Teams are working together and I think we're optimistic sometime next month," acting FAA Administrator Polly Trottenberg told reporters on the sidelines of a conference. >SpaceX would still need a separate environmental approval from the U.S. Fish and Wildlife Service before a launch. Trottenberg did not say how long that might take. It has been noted that the last paragraph doesn't say that Trottenberg said that. It might have been the reporter's inference that it is needed, and Trottenberg may not have addressed it at all. Also, for the PEA, the FAA handled all of it, including interfacing with the U.S. FWS and all other governmental entities.

Elon: we’re ready, just waiting on the license from the FAA
FAA: funny you should say that, we’re just waiting on you guys to fix the problems you had.
Sure it’s easy to think of the FAA as being a bunch of bureaucrats who should loosen up and cut SpaceX some slack, but after the rock tornado and wimpy FTS SpaceX has used up any slack it might have had.
Furthermore, the FAA is being sued alleging that it cut SpaceX too much slack on the environmental review surrounding Starbase. Any action they take could end up in court and they need to be sure it’s defensible before a jury https://www.space.com/spacex-faa-seek-dismiss-starship-lawsuit
Though someone else replied,
Setting aside that this answer is the same the FAA would give regardless of whether it was the day after IFT-1 or the day before they issued a license.
and Scott replied, "Correct".

From Ars Technica:
(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."
