    Very droll

    Musk recently posted details of the landing sequence for Starship's booster when being caught by the tower arms. Notable is the predominance of hover time, in contrast to the Falcon's hover-slam maneuvre. Falcon is forced to do this because of the insufficient throttle depth of the Merlin - it's unable to hover an empty booster. However, this is much more fuel-efficient compared with a hover. Starship will have to pay for the arm catch maneuvre in extra fuel mass.

    Now, the reason for catching arms is the elimination of landing legs, which helps for two reasons; increased available payload mass, and more rapid reusability. Although the latter reason is beyond dispute, the former reason seems questionable. It may well turn out that the extra fuel mass required to execute the hover-catch more than negates the mass saving gained by losing landing legs.

    Hope it works anyway.

    It was pretty cool to see the version 2 Raptor though.

    Yabut I'm getting to find Musk's extravagant claims increasingly exhausting.

    Are we really to believe that there will be an orbital flight in March (after having been told in the last "update" that it would be at the end of 2019)? That Raptor 2 will be half the cost of Raptor 1? That launch will occur with no water deluge for sound suppression and this will not damage the Orbital Launch Mount? ..etc. etc.

    Weren't we supposed to be witnessing SpaceX flights to Mars by now?
