    No hypergols? We don’t know that. They may use them in APU’s, they may/probably will use them as a backup power system. I bet hypergols will find a role.

    I don’t think so. My understanding is that Starship is being designed to be able to “live off the land” to the maximum possible degree – “the land” being Mars. Martian ISRU hypergols are a far trickier proposition than Martian ISRU methalox. The thrusters on Starship will be cold gas types. These can be replenished by just using the fraction of the Martian atmosphere left over after taking out the CO2 as methalox is made. Propellant tanks will be autogenously pressurized. There will be no helium-dependent subsystems either as helium is unavailable on Mars.

    SpaceX may have filed requests in Feb. for use of a particular airspace envelope, but the targeted first use date wasn’t Feb. Your estimates of the time required to fit out Starhopper, or even the prototype Starships with auxiliary systems is completely risable. Even Boeing doesn’t take anywhere near that long to do such work on one of their airliners and those puppies have a lot more subsystems than Starship is going to.

    This looks less dimpled.

    I wish Musk had went to Alabama–here esp.
