    The Starship Mk 1 orbital test vehicle is being stacked, with the nose cone (background) still to be lifted into place. This with the nose cone would be the cargo/passenger section on an operational vehicle, roughly the upper 35%±. The propulsion/fin-landing gear section is under construction.

    Most of the stainless steel still has a protective coating, so shiny isn't everywhere yet.

    This upper stage can sport up to 7 Raptor engines with at least 13.9 MN (3,100,000 lbf) of thrust, about 34% more than Russia's Proton launcher.

    County approves another round of SpaceX road closures

    SpaceX is preparing for a second round of testing at its Boca Chica Beach Launch Site.

    Cameron County Judge Eddie Treviño Jr. announced Tuesday that he has ordered the temporary closure of State Highway 4 from Oklahoma Avenue to Boca Chica Beach.

    The closure is scheduled for May 28 between 2 and 10 p.m. or in the alternative, on May 29 and/or May 30, according to a press release.

    The first round of SpaceX testing at Boca Chica Beach spanned a three-week closure during March where State Highway 4 experienced multiple closures while SpaceX tested its Starship Hopper prototype.

    Those tests concluded in early April when SpaceX fired up the Starship Hopper's Raptor engine and successfully completed a short "hop."

    So the teams dont know what the other is doing? Then learn the best lessons from each team? Then the losing team gets voted off the island?

    The opposite. Any insights gained by one team must be shared with the other, but other team not required to use them.

    Both sites will make many Starships. This is a competition to see which location is most effective. Answer might be both.

    SN4 is done. Hawthorne is working on SN5 now, but focus is ramping build rate of SN6 through SN10.

    Any prediction on when you expect to reach the "100 milestone" ie building the SN100 Raptor? I hope it is early next year. You'll need a lot of engines!

    News story about the Cocoa, Florida Starship build site. Flights are most likely from a new pad co-sited at LC-39A.

    The Raptor full-flow staged combustion methane engine has entered production.

    Turbopump propellant flow path to achieve high chamber pressure is quite tricky. Requires an inducer & 2 impellers with ~100,000 shaft horsepower.

    Makes no sense. In order to grow the colony, youd have to transport vast amounts of mass from planets/moons/asteroids. Would be like trying to build the USA in the middle of the Atlantic Ocean!

    What might the interior of the Starship be like. Will there be separate rooms for each passenger? Like I guess it needs to be attractive for paying customers on board.

    Super Heavy build: 3 months

    RaptorVac tests: 4 months

    We may well see a full-stack Super Heavy/Starship launch in 2020.
