  • 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!














  • I copied and pasted it here. Thanks to @[email protected] 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.

  • More pour info, this time from tweets from Zack Golden @CSI_Starbase. The truck counts basically match those from @[email protected]’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.

    and

    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

  • So the big news of the day and night was what is believed to be the center plate of the water deluge system. It is thought that it will be placed directly under the Orbital Launch Mount.

    @[email protected] already posted (at top level) “CSI Starbase video on new Deluge system”, a deep dive part 1. The URL I see for the post is https://lemmy.world/post/879748 , because that’s how I access this. The canonical one is https://lemm.ee/post/530280 .

    CSI Starbase SPMT Tracker @SpmtTracker posted a tweet with a picture of what is very likely to be a vertical stand for the center plate. The image is on Imgur. The tweet is here. Ryan Hansen Space @RyanHansenSpace tweeted a rendering of how it might look under the OLM. This should be the image:

    @[email protected] posted below (if sorted by new) a link to a 13-minute video by Starship Gazer, of people working in the tent on the center plate. https://lemm.ee/comment/534238 . Someone commented that, from 4 minutes on, it’s comedy gold. People were grinning around them. I’m told that someone is standing on top of the cheater pipe at one point.

    NASASpaceflight posted a video of the rollout of the center. It’s about 1 hour 26 minutes long. The stand / jig was on the first truck; the center plate with some people on it was on the next truck. The clearest views are about 17 minutes on.
