    Odds are the legs & fins will change on Super Heavy given Musk saying there will be leg mounted engines, but this artwork is pure speculation.

    Elon Musk ✔ @elonmusk
    Looks like @SpaceX Starhopper flight may be as soon as Monday. FAA support is much appreciated!

    Everyday Astronaut @Erdayastronaut
    Replying to @elonmusk @SpaceX
    Can you confirm this will be the last flight of StarHopper? Onto Starship prototypes next, right?

    Elon Musk ✔ @elonmusk
    Yes, last flight for Hopper. If all goes well, it will become a vertical test stand for Raptor.
    5:42 PM - Aug 24, 2019

    And at least 18 completed ring segments at Cocoa, FL - presumably for Super Heavy

    StarHopper's final flight tomorrow.

    This would be Central time. Adding 1 hour for Eastern;

    Date: Monday, August 26
    Window: 1700-1715 Eastern

    Brownsville Herald...

    Cameron County's Office of Emergency Management has sent out a notice alerting residents of Boca Chica Village that SpaceX plans to do some testing on Monday that could possibly break windows at their homes.

    According to the alert, SpaceX will conduct flight activities from 4 p.m. to 4:15 p.m. and "there is a risk that a malfunction of the SpaceX vehicle during flight will create an overpressure event that can break windows."
    >
    Officials are recommending that residents leave their homes at that time during the SpaceX flight activities. They say, "at a minimum, you must exit your home or structure and be outside of any building on your property....to avoid or minimize the risk of injury."

    “Overpressure event?” Is that Musk-speak for “it blew up?”

    That's Emergency Management-speak for a boomski.

    Dealt with those guys for our trauma center & health dept. disaster, terror, radiological event and other drills. Much translation required.

    Or an RUD.

    Am I the only one that STILL can't take seriously a spaceship that's being built in the open by a bunch of welders out of steel sheets? I keep expecting Elon to keep it going until 4/1/20 and say "Gotcha!".

    Steel sheets were only for the early test vehicles; StarHopper and Starships Mk-1 (Boca Chica) and Mk-2 (Cocoa). Got 'em started while tools were being fabbed.

    They've already transitioned to ring segments made from Outokumpu roll stainless steel - there are 18+ laying about at Cocoa for what's likely a Super Heavy build. Not too different than Falcon 9 and Falcon Heavy, but not Lithium-Aluminum. Domes are being built on a tool similar to what's used for SLS domes.

    As for being built outside; so are most ships. And, the tank welding is mostly automated seam welders, followed up by x-rays.

    A couple of weeks/months ago Musk said that Starship development can still be accelerated significantly. I assume that's why we are seeing what likely is a SuperHeavy prototype being built already? Faster switch from Starhopper to Starship prototypes, faster switch from multi-plate to single plate ring construction...
    With sufficient thrust, water towers fly just fine.

    Wow. This is the most amazing thing to me, so far, about this very exciting development process. I'm very surprised that SpaceX is being allowed to do these tests given the risks implied in the above quote.

    Reading that again, it sounds as if I don't respect welders. That's far from the truth. I spent half my career designing welded structures. Those guys are awesome.

    This build of Raptor has about 390,000 lbf of thrust, a bit less than the Space Shuttle Main Engine. The Boca Chica spaceport Environmental Assessment cleared it for Falcon Heavy - 5.2 million lbf.

    This sort of warning to nearby residents has been seen before; when Orbital Sciences & NASA launched the first Antares from NASA Wallops in VA.

    Just remember: this is a boilerplate vehicle testing new and risky things. If it craters, it's a learning experience. SpaceX flies, learns, corrects and reflies rather than simulate things to the point of inaction.

    Sounds like an electric igniter issue

    Elon Musk ✓ @elonmusk
    Raptor uses dual redundant torch igniters. Better long-term, but more finicky in development

    I'll hand it to Twitter's message length that dual redundancy is given as the reason for a failure.

    Today's Starship Mk2 video from Cocoa FL shows the hangar door progressing, and 19+ Super Heavy ring segments.

    I have that on. Wish we knew just when. I gave up on Tim Dodd's feed, down more than up.

    I'm currently stress-testing my cable company's bandwidth by streaming both channels at once!

    Apparent built-in hold at T-2.00.
