    Default SpaceX Starship & Super Heavy updates (thread 2) [SN8 engines mounted]

    With high altitude test flights and a major update from Musk coming up, time for a new thread.

    Thread 1...

    Starting off with the US Transportation Command looking at Starship Earth-2-Earth for high speed logistics. Basically, Starship E2E is said to be capable of hopping 10,000 km without a booster. Looking at a test next year, 80 tonnes of payload

    Pentagon wants SpaceX delivering cargo around the globe — and a live test could come next year

    WASHINGTON — U.S. Transportation Command is taking the potential for cargo delivery via orbit seriously enough that it hopes to test the concept with SpaceX as soon as next year, the command’s head said Wednesday.

    In what he called a “provocative thought,” Gen. Stephen Lyons said: “I’m really excited about the team that’s working with SpaceX on an opportunity, even perhaps in as early as ’21, to conduct a joint proof of principle” for space-based delivery.

    The dream, Lyons told the National Defense Transportation Association, is to be able to move 80 tons of cargo - the equivalent of a C-17 transport - via a space-based vehicle anywhere on the globe within one hour.

    How to get the cargo on the ground? Elevator.

    The concept for NASA's Commercial Lunar Cargo Services (CLPS) shows where they're heading,

    ITAR = International Traffic in Arms Regulations

    Transpirational cooling = heat shield tiles which "sweat" a cryogenic fluid, most likely liquid methane

    Tiles will be on hot side of flaps too. A very tough problem is sealing the moving flap to body joint without melting or shredding the seal.

    Are you still considering transpiration cooling for most vulnerable hotspots or are the heat shield tiles tough enough?

    It might be used in some areas. ITAR laws prevent us from being too specific about solutions

    Fanart but pretty accurate image: Starship/Super Heavy stack atop the new launch table, currently under construction. The tower build can wait for a bit.

    Sounds like the SN-08 fun's starting; 3 Raptor engines headed to the pad. Payload section in the wings.

    1) static fire #1 campaign
    2) data analysis
    3) mount payload module
    4) static fire #2 campaign (?using landing header tanks?)
    5) flight to 15+ km, skydiver landing

    Austin Barnard @austinbarnard45
    SpaceX's Starship SN8 now has all three Raptors mounted into the aft compartment. We are only a mere few days away from the Static Fire test campaign, as the 15km flight inches closer by each passing day.

    Possible 3-engine static fire tonight

    Window is 2200-0700 Eastern

    LabPadre will be installing a seismograph for their livestreams
