    Moving built parts & jigs to Texas in order to speed up Mk3 could make sense...

    @gregscott_photo
    SPACEX STARSHIP: 2 Starship bases & a Bulkhead that had been removed from the Cocoa site have just been loaded onto Go Discovery in the Port. My guess is that they are on their way to Boca Chica, but thats just my guess. Care to
    enlighten us @ElonMusk? #SpaceX #Space #Science

    Why would they be taking it to Texas, instead just over the Intercostal to KSC?

    To speed up Mk3 at Cocoa, which with the new ring making tool will go *much* faster since the new SpaceX Operations Area (SOA) at KSC is still getting organized.

    The LC-39A Starship pad build is progressing nicely,

    Julia @julia_bergeron
    In all of the excitement about the goings on in port I forgot to post these from #39A this morning. Starship pad construction progresses despite the lack of launch vehicle. I bet photogs could get a sweet shot from this camera mound. #Starship

    The SpaceX Operations Area at KSC and LC-39A Starship mods need finishing.

    Michael Sheetz ✔ @thesheetztweetz
    SpaceX says it paused, but has not fully stopped, Starships development in Florida while the company focuses on building Starship Mk3 in Texas.

    The US Coast Guard is allowing SpaceX to establish private AIS* Aids To Navigation (ATON) virtual markers - essentially launch exclusion zones that'll show on AIS.

    *Automatic Identification System

    https://www.maritime-executive.com/a...gation-markers

    SpaceX Gets its Own AIS Aids to Navigation Markers

    Satellite launch contractor SpaceX will soon be using its own private AIS Aids TO Navigation (ATON) to mark the temporary exclusion areas it uses during rocket launches at Cape Canaveral, Florida. It is the first official Coast Guard approval for a "dynamic" restricted area.
    >
    >
    The company's non-charted safety zones will be established from Cape Canaveral, Florida, into the Atlantic Ocean in four different areas, which will be activated individually based on the rocket's planned flight path. The safety zones are designed to keep vessels from entering the area while a launch is taking place.

    The four launch zones for SpaceX have been in use for some time, but to date, their periodic activations have been announced to the maritime community through the Coast Guard Notice to Mariners and Local Notice to Mariners. The first zone to be marked by SpaceX's own AIS ATON is scheduled for a launch this week.
    >
    >
    Like other AIS markers, the SpaceX AIS synthetic ATON will show up on AIS-enabled ECDIS systems and electronic chart plotters.

    Looks like the time on that has changed; Spaceflight Insider had (still has, in fact) it several hour earlier. Would have been before I get up, now it's not. Yay!

    KSC LC-39A Starship pad: whoa...what happened to Phase 2? Straight to Phase 3??

    The Starship mount doesn't use a flame trench - it's an elevated platform, or "milk stool," with a cooled flame diverter and a huge water deluge. Somewhat like Saturn 1B used.

    @abernnyc
    It's absolutely incredible to see the progress @SpaceX has made on the #Starship launch mount currently being constructed at LC-39A

    @13ericralph31
    Off the top of my head, this looks at least as tall as the mount/stand shown in SpaceX's updated 2019 renders. So it's probably safe to say that 39A is going directly to a Super Heavy-capable pad, which would make a lot of sense after the pause on FL Starship production.

    https://twitter.com/13ericralph31/st...45014808137730
    |
    @13ericralph31
    Based on these renders, the mount shown is 80-100 ft (25-30 m) tall. Based on Adam's photo, assuming the dude getting off the lift is an average ~6 feet, the steel skeleton is already ~70 ft (21 m) tall and clearly has some mounting points for another big addition on top of that.

    https://twitter.com/13ericralph31/st...49363861041152

    @rdstrick777
    Its at least 85 feet tall and the Starship Superheavy launchpad is around 100 feet, I think you got it.

    https://twitter.com/rdstrick777/stat...48765405167616
    |
    @13ericralph31
    Yeah, I estimated 70 feet tall not including the mounting point protuberances, which are clearly designed to support something VERY heavy above them.

    In standard safety glass holed by bullets from mafia hits--the holes were surrounded by far less cracking, IIRC.
    You may want much cracking to the sides, to rob the projectile of energy--as here: https://phys.org/news/2019-11-theore...-polymers.html

    You mean his "scoop" about not x-raying welds?

    Interesting take given we've seen the clearly marked (☢️) isotope storage shed, x-ray testing gear, and it being used.

    ASDS Just Read the Instructions has spent the summer near NOLA getting upgrades, including new beastly automatic positioning thrusters.

    Now SpaceX can catch both Falcon Heavy boosters downrange, expending the center core for high-deltaV launches.

    Or,

    They can do rapid sequence Starlink etc. launches with downrange recovery. SpaceX plans on up to 24 Starlink launches in 2020, at 60 satellites each.

    ----------

    Next Horizons SpaceFlight @NextHorizons_
    Just Read The Instructions arrives in @PortCanaveral! We now have 2 East Coast droneships! You can see lots of stuff on the deck, including 6 new massive thrusters for station keeping. #JRTI #SpaceXFleet

    Technical reasons to mitigate the brightness, or avoiding a future where one cannot spot stars because a disco ball of 50k satellites is shining across all the time?
    With sufficient thrust, water towers fly just fine.

    Specifically to mitigate the apparent manifest worst case scenario of the constellation being more visible and for longer than originally advertised. More specifically, there is a huge concern in the astronomy community of the effect Starlink will have on various ground based surveys and upcoming telescopes like LSST. It's especially troublesome for high-latitude observatories where the satellites will be visible for most of the night during parts of the year.

    I forget the exact acronym, but "CRS" refers to Dragon missions to the ISS. Commercial Resupply or some such. The note appears to indicate that this same booster was used on the previous two missions; the latest being CRS-19.

    ETA: Commercial Resupply Services, apparently.

    Just his grousing I suppose. So, how would the SLS and Starship tank failures compare, psi wise. I've heard it said that SLS did well after exposure to more than 260% of expected flight loads over 5 hours--but at non-cryogenic temps though.

    Something to think about. The SLS “core stage pathfinder” was made by G&G Steel:
    https://www.ggsteel.com/industries/dod-aerospace

    I wonder if SpaceX might think about working with them. I really like the smoothness of that pathfinder. Perhaps for wider Starships/Super-Heavies?

    Midway in the Mk1-2 builds, which made rings using steel plates, SpaceX iterated the design to use monolithic (one piece, single weld) rings fabricated on new tooling from IMCAR in Italy.

    https://youtu.be/VdX4IfsGY4Q

    Now they're cranking out rings at Boca Chica, more IMCAR hardware just arrived, and the Florida build is being moved to a new \omegafacility being built inside KSC, south of the Vehicle Assembly Building.

    Once that change happened Mk1 became redundant, so they used it to test be the ground support equipment. Rumors are a GSE element failure allowed the tank to over-pressurize and blow.

    Since they've done nothing to dismantle Mk2 it's possible it'll be used similarly; GSE tests and fit checks on the new Super Heavy/Starship launch mount being constructed at LC-39A. It's a total beast, with the launch clamps almost 100 feet off the ground.
