    Do they have plans of testing all the engines at one time?

    No statement, but given they're rolling more engines to the test pad, it sounds like incremental testing.

    Also.

    If all goes well, Starship will be ready for its first orbital launch attempt next month, pending regulatory approval

    Here we go...

    Additional Raptors are being installed on Ship 20 tonight. Expecting another static fire as early as next week, possibly with several engines. Road closures begin Monday.

    Talking RVac

    Elon Musk ✓ @elonmusk
    Raptor has a very high chamber pressure, which in turn allows for a large expansion ratio nozzle without flow separation at sea level
    |
    Currently at ~270 bar, but working on upgrades to get it over 300 bar
    |
    Got to 321 bar before RUD, but cause may be due to oxygen inlet pressure too low, rather than engine issues

    I got my rocket engine to 7 bars. Granted, it was a water bottle, but it's something. And it flew 40 meters higher than the BE-4 engine.
    With sufficient thrust, water towers fly just fine.

    So how did you get it to 7?

    Mine were the old fashioned type with a hand pump.

    True but the stored energy available to be converted is limited.

    That's why there are people building staged multi-core water bottle rockets.

    Still not the way to space, obviously, but fun and educational. And quite safe if you don't go too far above 8 bars per bottle. Otherwise, they'd become like lawn darts with extra explosive potential.

    Cool. It looked like some of the early flight needed a gryo but later looked all vertical.

    I grow rather weary of my inbox being inundated with glom and doom emails concerning the "dire" situation with getting approvals for Boca Chica facilities and FAA approvals for launches. Given that there is a great amount of interest in this approval proceedings, I don't think that it will ultimately be disapproved. It may take some tweaking by SpaceX of the paper work associated. I don't believe that the lawyers are not at work "full time" to appease the regulators in whatever their fears about the environment might be.
    I just wish this to be over and let SpaceX go about the development. I personally have been at this "area" some years back and I don't remember this a wilderness paradise.

    The launch of SpaceX Crew-3 has been delayed until no earlier than Wednesday, November 3 at 1:10 AM EDT due to downrange weather.

    Oh, I'd forgotten that was coming up! Thanks for the reminder.

    Down in Boca Chica, the chopstick arms have moved for the first time and Frankencrane is laid down, perhaps to be disassembled and leave.

    Were in Tampa this week and the weather is clearing so maybe ill stay up for a few extra hours and watch the launch. Even with a 51 degree inclination we should be able to see the launch path. Not sure about staging and booster return.

    SpaceX just took delivery of a custom Liebherr LB11000 crane, all dressed up in black & white SpaceX livery.

    I watch the NSF videos every day. They've been quite the good advertising for Liebherr!

    One thing I've found amusing in the videos is that you very often see Grove cranes and JLG Ultra-Boom lifts. The companies are not connected but both are named for the same man, founder John L Grove, along with his brother in the case of the crane company.

    What's more important to them is the daily/monthly rental.

    ETA And I expect the rental is substantial.

    First thing I'm doing when I get my TARDIS working is go back and get the United Rentals franchise for Brownsville!

    Crew 3 is off until at least Saturday, due to "a minor health issue" with a crewmember. 11:36 PM Eastern.

    NASA's press release specifically says not. I'm sure that would entail more than a three-day delay.
