  • I chose the title because I thought and hoped it’s a reasonable inference.

    As an example, the first time I booked my own air flight – actually, every time – I made sure it was a ticket for the days and places I want, and that I got to my home at the end.

    Do you know more about this Varda licensing situation? Is it possible to get a re-entry licence before launch? If they could have, they’re incompetent not to. If not, that seems like a ridiculous regulation, requiring someone to launch with no confidence that they can legally come back (and possibly still incompetence on Varda’s part for not making sure all the conditions were going to be met).


  • As You999 put it, “the laws of the country that the craft is registered still applies”. I hadn’t heard the term “the Chicago Convention”. I’ve heard only “The Outer Space Treaty”, or formally Treaty on principles governing the activities of states in the exploration and use of outer space, including the moon and other celestial bodies. Specifically Article VIII:

    A State Party to the Treaty on whose registry an object launched into outer space is carried shall retain jurisdiction and control over such object, and over any personnel thereof, while in outer space or on a celestial body. Ownership of objects launched into outer space, including objects landed or constructed on a celestial body, and of their component parts, is not affected by their presence in outer space or on a celestial body or by their return to the Earth. Such objects or component parts found beyond the limits of the State Party of the Treaty on whose registry they are carried shall be returned to that State Party, which shall, upon request, furnish identifying data prior to their return.

    Could Varda actually land the capsule? I presume so (the whole thing is a moot point if they can’t). Would the FAA (and, for all I know, other agencies) land on them like a pile of bricks? I certainly hope so!





  • 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.








  • 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.





  • 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.










  • I copied and pasted it here. Thanks to @threelonmusketeers@sh.itjust.works for pointing me back at the RES extension so I could get the source.

    Each item is on its own line. C## is the ID#. If there’s text before it on its line, that’s its Observation / Description section name; if it’s at the start of the line, the Observation / Description string is the next one above.
