    SpaceX has been SANDBAGGING!! AGAIN!!!

    The launch host reported they already have StarLink satellites up with laser inter-satellite links, and have transferred "hundreds of gigabytes" o_0

    Qapla' !!!

    Little bit of a fire from a small tube at the bottom of the skirt that flared previously, but the water cannon put it out.

    Likely. THey're reusing lots of the stuff from prototypes. Wings, the entire Starhopper, low SN test tanks, and now apparently just the basic steel. Smart. It's not because your venture costs billions that you shouldn't save where possible.
    With sufficient thrust, water towers fly just fine.

    Ok. Thanks since I don't speak Klingon.

    SN6 DID IT!!!!!

    Starship SN6 flew a similar hop to SN5, but it was a much smoother & faster operation

    Quite a major tilt on S/N 6 after landing. I noticed that on 5 as well but 6 was worse. Probably an inevitable result of the off-center thrust, requiring it to fly with a tilt and touch down on just one or two legs, crushing them more than the others.

    I love what they are doing, but it does look like they are trying to launch a silo into space.

    Think of it as the propulsion module of a larger vehicle. The cylindrical shape is form following function.

    Next week there is a road closure, likely SN-06 going back to the shipyard and the SN-07.1 test tank going to the new test stand. SN-07.1 is made of a custom 30L stainless alloy used for the SN-08 and later vehicles, and will be tested to failure.

    SN-09 and SN-10 construction has begun.

    SpaceX released their video

    The talk of larger rings is about Musk saying the base diameter of Super Heavy being 10 meters to better accommodate the engine count.

    And I love it. Test doesn't need a nosecone or wings? Don't put them on, even though some are available. Markings? Just put some blue tape on it, if it's readable it's fine. No time and money wasted on anything that doesn't add to the test.

    The SLS SRB test had a fancy US flag painted on, but I doubt anyone at Boca Chica was feeling jealous.

    Just talking bell size here it ain't no F1 in size but it's good to see a new rocket engine large enough to be repurposed as a comfy bus stop. And the amount of thrust with 30+ of these being lit at once would make any Saturn V proud. Exciting times!

    Won't be 30 of those, thats only for the superheated first stage which would have the sea level version .

    RVac is for the 3 outer ring Starship engines and won't gimbal. The center cluster will have 3 sea level engines which gimbal for landings & steering..

    Super Heavy will have 28 Raptors; 8 in the center cluster and 20 in an outer ring. The center cluster Raptor engines will have deep throttling and a 15 gimbal for thrust vector steering. The outer ring will be Raptor Full Thrust engines with no gimbal and limited throttling if any. Big Push motors.

    With the full set of 28 engines it'll start out at about 15 mlbf and evolve closer to 17 mlbf (6600-8000 Tf), but Musk has said it can fly with a lower number if the mission doesn't need the full set.

    Now, I have heard it said that there was some Saturn V tooling still extant somewhere—would that be helpful?

    They're already talking about a larger Starship - up to 18 meters.

    SN-06 has been placed on the transportation mount for a trip to the shipyard.

    Next up: likely the SN-07.1 test tank. Ground Support Equipment & pressurization tests, then a Test to Destruction to find its limits.

    Now, about the tiles. I seem to remember some talk on Portree’s site (formerly Beyond Apollo) that talked about snap on ablative panels some thought to use on shuttle orbiters.

    Then too, there may be some forgotten paper that talks about a tile tesselation sequence which prevents spalling. Or the paper might be in the preformed concrete panel industry, which touches on how hard it is to clad flexing cylinders.

    I have seen corrugated skin on the Ford Trimotor, and I think I saw width wise corrugated Dyna Soar art, though that would not be aerodynamic. Maybe hyperbolic “paper” filler that doesn’t like flat surfaces anyway. Trying to think of something...

    The RocketCam sights and sounds of a Falcon 9 launch and landing.

    Headphones recommended.

    Very cool. One tends not to think about sound at the height of first stag burn out, but it was neat. The landing noises are hear very often either.
