    The lights under StarHopper? Given the tables under StarHopper it looks like a small work & break area.

    Well, Starhopper certainly makes for an unusual dining area umbrella or cover.

    No, I was talking about the three up high. Probably on the other side from that picture.

    There are high/low lights, antennas, PA speakers, a siren, weather sensors, radar and cameras. Looks like it's just a convenient high place to mount stuff.

    There may be a Super Heavy hop by October o_0

    Any update on this year’s Starship event? Still aiming for September?

    Elon Musk @elonmusk
    Neuralink this month & Tesla next month, SpaceX probably October. We will have made a lot of progress by then. Might have a prototype booster hop done by then.

    So, a 2 engine Super Heavy hop before October's SpaceX update event

    Raptor today: 210 Tf = 462,971 lbf
    Raptor in 6-9 months: 250 Tf = 551,156 lbf
    RaptorVac progressing well (short nozzle tested, long nozzle test upcoming)

    Now they're just showing off...

    Weather permitting, SpaceX Communications confirms a Sunday two-fer at the Cape, and there's a possibility SN-06 will hop at Boca Chica

    Starlink from LC-39A at 1012 ET
    SAOCOM 1B from LC-40 at 1918 ET

    This morning's launch postponed due to weather. Looking iffy for this afternoon as well.

    May be an S/N 6 hop today, I think.

    ETA: That Superheavy stand is one water tower that's not going to be flying, regardless of thrust! At some point I assume they'll need an actual water tower as well.

    Looks like the evening launch is still on...

    Launch of the SAOCOM 1B radar observation satellite atop a Falcon 9 booster with a previously flown first stage was targeted for 7:18 p.m. EDT from pad 40 at the Cape Canaveral Air Force Station. Also on board: two small hitch-hiker satellites added to the flight under a "rideshare" arrangement.
    ETA: Weather permitting. About 40% chance of a launch says SpaceX.

    Targeting launch of SAOCOM 1B at 7:18 p.m. EDT tonight. Falcon 9 and SAOCOM 1B are vertical on SLC-40. Weather continues to be 40% favorable for liftoff

    Too bad, it would have been glorious

    Yeah, that launch table is a friggin' beast.

    No hop yesterday, but one of two F9 launches went off without a hitch!

    I keep wondering how they're going to fair in or otherwise deal with all the external tanks, plumbing, and wiring you can see on S/N5 and 6 when it gets to a high altitude version. But I heartily approve of doing it the way they are doing, keeping it simple for the test hop vehicles.

    They never say. The previous S/N5 one took several attempts, as did the static fire of this one.

    As it is, I’m amazed by how much they do say. They’re under no obligation to tell us much of anything about development. Compare to Blue Origin, which is very secretive.

    I am particularly impressed with the landing of the first stage, it looks amazing!

    The word is high winds, which is why they've postponed testing for the next few days as well.

    They are, however, building a tall opaque fence between the road and the launch site.

    Especially when you consider this was the fourth time this latest booster has done it!

    Schedule;

    Thursday Sept 3: SN-06 hop
    Sunday Sept 6: SN-07.1 tank pressure test

    Iffy weather for SN-07.1

    Looks like they're converting it to a giant R2D2 like robot and those are the visual sensors.

    Would the fence they're building between the launch site and the road allow for tests/launches without road closures? Perhaps at least some ground operations without closures.
    With sufficient thrust, water towers fly just fine.

    No.

    StarLink v1.0 Launch 11 (12 with v0.9 test birds, which are being deorbited)

    Funky music.

    This will be the 2nd launch this week, and both without a static fire.
