    i just realized that unlike the Starship prototypes, the engines protrude out the bottom instead of being contained within a skirt. Presumably that's the reason for the extra structure added to the test stand.

    I may be wrong, but I think he's referring to Musk's planned ride on SpaceShipTwo.

    Blowing the picture up, I can read "SPIFF" on the helmet. Calvin and Hobbes reference?

    Ah, thanks. I thought it might be a reference to some comic but I had no idea what it would be. I blew it up too, but that “spiff” is very small and I missed it.

    CHOMPER!! (the front section anyhow...)

    They build the payload section in 2 halves; a lower cylinder and the "nose" which is this. Acording to the Starship User Guide there'll be 2 sizes of payload bay; the "Standard" 17.24 meters long and the "Extended" 22 meters long.

    Falcon Heavy to launch Europa Clipper

    This was originally planned as a Space Launch System mission.

    https://twitter.com/SpaceX/status/1418667693016711170

    Jul 23, 2021
    RELEASE 21-098

    NASA Awards Launch Services Contract for the Europa Clipper Mission


    NASA has selected Space Exploration Technologies Corp. (SpaceX) of Hawthorne, California, to provide launch services for Earth’s first mission to conduct detailed investigations of Jupiter's moon Europa.

    The Europa Clipper mission will launch in October 2024 on a Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The total contract award amount for launch services is approximately $178 million.

    Europa Clipper will conduct a detailed survey of Europa and use a sophisticated suite of science instruments to investigate whether the icy moon has conditions suitable for life. Key mission objectives are to produce high-resolution images of Europa's surface, determine its composition, look for signs of recent or ongoing geological activity, measure the thickness of the moon’s icy shell, search for subsurface lakes, and determine the depth and salinity of Europa's ocean.

    NASA’s Launch Services Program at Kennedy will manage the Europa Clipper launch service. NASA's Jet Propulsion Laboratory in Southern California leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, for NASA’s Science Mission Directorate in Washington. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, executes program management of the Europa Clipper mission.

    Ars Technica had an article about the launch choice for the Europa Clipper:

    https://arstechnica.com/science/2021...ce/?comments=1

    The cost from SpaceX is about $178 million, but for SLS it would have been about $2 billion. In addition, the SLS’s solid fuel boosters make for a rougher launch and that would require reinforcements on the Clipper for another $1 billion. In addition, there could be (in fact, almost certainly would be) availability delays for SLS that would incur additional costs depending on the length of the delay. So less than $200 million versus at least $3 billion, which should be an obvious choice, but there were political pressures that slowed down the selection process.

    Even if the SpaceX estimate is off by a factor of five, itís still the better bargain.

    Why is there never this kind of political pressure favouring my company.
    With sufficient thrust, water towers fly just fine.

    Compared to the traditional amount of delays in space hardware development, Elon Standard Time is still very accurate. Just add quarter...

    I just read where 3 of the Raptors were shipped back to McGregor any news on why they were returned?

    They often do that after static fires. They get torn down, examined, and lessons are learned.

    And that’s just the primary fuel lines! The maze of secondary plumbing & wiring is our greatest concern.

    Raptor V2.0 is a major improvement in simplication, while also increasing thrust from ~185 tons to ~230 tons. Long-term goal is engine cost below $1000/ton of thrust.
    https://twitter.com/elonmusk/status/1420826978102435845

    So about $230,000 for. Raptor 2.0. An RL10 (Centaur engine) costs ~$30 million.

    Inspection/refurbishment, I expect. And three more have been delivered.
    Meanwhile, they've assembled and installed a 9th segment to the launch support tower. Unlike the previous square ones, this has only three legs but has a beam assembly extending out from the middle leg with some large sheaves out there. Presumably there are another set of sheaves at the back to connect with the hoisting machinery ("draworks") at the bottom which they took off one of the drilling platforms they bought.
    What I'm not getting is that while this setup has a pretty significant hoisting capability, it's at a fixed location. And does not extend far out from the tower.

    Hotels near capacity as several hundred SpaceX employees arrive in Brownsville in preparation for orbital launch

    BROWNSVILLE, Texas (KVEO) —*Development at the SpaceX Boca Chica launch site is ramping up under orders*from company CEO Elon Musk, in an effort*to finish the orbital launch tower and stack the Starship and booster prototypes*before launching into orbit.[...]

    [....]Musk has called*on*500*employees from*SpaceX sites in Hawthorn, California, Cape Canaveral,*Florida, and McGregor, Texas, to*relocate*to the Brownsville/Boca Chica area temporarily.*
    >
    While a date has not been set for the orbital launch, a source shared with KVEO that Musk gave them a short timeline of nine days, as of Friday,*to have the vehicle stacked at the launch pad.

    We've used a similar design to have a crawler run along a boom, or in this case side of the tower. That crawler can then be equipped with eg a gripper.

    I thought of that, but this looks very much fixed. Or were you saying a crawler to run up and down the tower? That could make sense, although I haven't seen any tracks.
    Meanwhile there was a brief video yesterday by RGV Aerial Video showing what they suspect is part of a booster catching arrangement.

    The cable could be attached to a tensioner in turn then to the catchers.
    Where did you see an aerial view this week? The most current one I have is from the 20th.
