pigeonberry, to spacex in Starship launch attempt Friday!

The licence has been approved, the NOTAM and marine warnings published, closure announced.

pigeonberry, to spacex in FAA have issued the launch license for IFT-2!

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”.

pigeonberry, to spacex in FWS considering the water deluge system at Starbase; has up to 135 days to submit the final biological opinion to the FAA

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.

pigeonberry, to spacex in (SpaceX) New Starship render and pictures

I’m sorry, but I don’t follow what you’re referring to. I think the new render is near the top, showing Starship and Super Heavy stacked. I didn’t look at the page before, so I don’t know what else might have changed.

Just wanted to point out a glamor video of Starlink deployment.

pigeonberry, to spacex in (Reuters) US could advance SpaceX license as soon as October after rocket exploded in April

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.

When the major problems from your first test can be illustrated by Heath Ledger in 2008 – debris zoom but boom no boom – it’s not surprising.

pigeonberry, (edited ) to austin in YSK: Austin, TX has a web and mobile app to report non-emergency incidents

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.

pigeonberry, to spacex in New launch tower segments moving to SLC-40 at Cape Canaveral

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.

Thank you for the pointer. Fixed.

Starship is the biggest rocket ever built 🤯

Elon Musk @elonmusk / Replying to @teslaownersSV Sep 9, 2023 · 6:20 AM UTC

Likely to be 10% to 20% longer in later versions
