    Try it yourself. It is easy with a software like Irfanview. That's what I used.

    I am lazy. Others have drawn a vertical line then counted pixels and did some math. The method I used is a lot easier and I am pretty sure it is more precise too.

    A nice pop of a test tank last night. They have tested their build SN7.1 to intentional destruction. We are now waiting and hoping that Elon Musk will reveal the pressure that was reached when it popped. He frequently but not always gives those numbers. What they need for a human rated vehicle is a burst pressure of 8.4 bar, which was likely reached but we don't know. This tank was built with a new steel alloy. New for SpaceX Starship, but still off the shelf everyday steel available from many vendors.

    The tank was filled with liquid nitrogen and then pressurized. A nice visual effect.

    Next will be Starship SN8. This one is intended to do the first flight to higher altitude, 20km, then fall down in a horizontal position, stabilized by 4 aero surfaces, until it turns vertical for engine powered landing. A fan animation showing the process. Elon Musk saw it and confirmed that it will be very much like this. SN8 is almost ready for initial tests and we hope it will do this flight before end of October. Elon Musk believes it may survive. But excitement will be guaranteed success or fail. If it fails, they will have SN 9 and 10 very soon to repeat the test. Every build will have improvements over the previous ones.

    A photo of SN8 with one aerosurface already installed.

    Operations at Boca Chica continue at breakneck speed. Presently they are building the orbital launch pad for the full Starship stack. The most powerful rocket ever designed. Also a new highbay with 81m height, for assembly of the first stage of that rocket only. The building has space for housing 4 huge first stages. The first and second stages are intended to do up to thousands of flights. But they are preparing to build them at build rates not achieved since the cold war when hundreds of ICBMs were built in a year. Preparation for building a City on Mars which will require millions of tons of materials to be shipped to Mars.

    We can doubt it is achievable. But we should not doubt that Elon Musk is preparing to make it happen.

    SN8 was built in the building now called midbay because it is smaller than the new highbay building. The picture is in front of midbay.

    BTW the motors driving the aerosurfaces and the batteries driving the motors are off the shelf Tesla products.

    Note that this is the second stage and does not have the cargo section yet, only the propulsion section. The first stage will be a lot bigger than that. They have now begun building the first test version of the first stage too.

    Payload fairing with the upper flaps was added. It is a full size upper stage now. The part that will go to Mars, once ready. Getting closer to the first flight up to 15km. Still some work to do.

    For size of that thing look at the people in a cherrypicker about half way up. A much bigger version of this pic for those who like to look for details. The whole area is still a construction site. Watching the live YouTube channel you can see an endless stream of dump trucks bringing in sand and concrete trucks.
