    The new High Bay structure for stacking Starships is almost complete. They'll build the cargo bay/habitat section, propellant tanks, and the thrust module and assemble them in there.

    Starship SN-01 should be going to the pad for tests & a static fire by early March - soon after stacking in the new High Bay. If all goes well, a flight test a few weeks later.

    Starship SN-02 is hot on its heels, with components being built, rings & domes stacked, with vehicle stacking after SN-01 vacates the High Bay.

    They want to scale production to 2 Starships a week in order to populate the operational fleet.

    Yes, a fleet.

    Hardest problem by far is building the production system of something this big. 2nd hardest is achieving full & rapid reuse with payload to orbit of ~2%.

    These problems are fundamentally intertwined. Building many rockets allows for successive approximation. Progress in any given technology is simply # of iterations * progress between iterations

    Given the number of Falcon 9 iterations since 2011, including a huge number of little tweaks w/ each new vehicle, how many iterations do you expect to need to achieve similar or much better reliability as F9 w/ Starship?
    |
    Elon Musk ✓ @elonmusk
    F9 iteration slowed down as payloads became too important to risk. Little change is expected going forward with F9/FH or Dragon. Starship production & thus iterative improvement will be much faster than Falcon. Driving hard for fully reusable orbital flight this year!

    So initial Starship flights will be unmanned? Or are people not a payload too important to risk...
    With sufficient thrust, water towers fly just fine.

    Ballast first, humans after they're confident.

    They also need to prove different types; Chomper, Tanker, Cargo Lander, Crew Lander. Also, on-orbit refuelling which is being worked on with NASA.

    The types differ mainly in the nose cone .

    I assume you are referring to in orbit refueling, and yes that might be a bit of a challenge.

    Tail-to-tail props transfer between Starships. Super Heavy and Starship have internal propellant "umbilical" plumbing.

    USAF and USSF could be major Starlink profit centers, and a bit of regulatory grease.

    Gen. John Raymond is Chief of Space Operations, US Space Force

    Michael Sheetz ✓ @thesheetztweetz (CNBC)
    Dr. Will Roper, the head of U.S. Air Force acquisitions, says the branch will have a "massive" demonstration event on April 8 that will include testing applications of SpaceX's #Starlink satellites to "a greater degree," connecting to platforms both in the air and on land.
    |
    The Air Force already tested Starlink satellites by linking them to military aircraft in flight, reporting early favorable results.

    Gen. John Raymond has notably visited SpaceX's Starlink factory in Redmond, WA.

    "SpaceX has been a great industry partner for us," Roper told reporters on Friday.

    "They are very excited, and we are excited to learn more about their satellites through the demonstration."

    NOW it is starting to look like a legitimate spacecraft assembly facility.

    This vehicle is only for atmospheric flight to 20km to test the belly flop & landing, so they're not letting perfect be the enemy of good enough.

    For SN-01, they're lapping & reinforcing the major subassembly joints. Easiest way is to do rough sizing of the smaller ring rim, slip the larger one over the smaller by pushing the smaller one in, tack weld the perimeter, hammer the dent out and reinforce the perimeter using slot welds.

    Proper tooling for later builds is on the way.

    ----------

    SN-01's propulsion module kas been moved to the pad for cryotreating & tests. After that, a static fire and the 20km flighr.

    Getting the crane & load spreader ready to place it on the test pad.

    You don't think there are bugs alive/dead in the VAB?

    There was a reason to have a VAB and not open air to build rockets. This isn't the V-2 era.

    We had the wrong settings! To make the welds super flat & strong, we’re building a heavy duty, custom planisher, but just having the right settings is a major improvement.

    Falcon Heavy will launch the probe to asteroid Psyche

    https://www.nasa.gov/press-release/n...psyche-mission


    CONTRACT RELEASE*C20-006

    NASA Awards Launch Services Contract for the Psyche Mission

    NASA has selected SpaceX of Hawthorne, California, to provide launch services for the agency’s*Psyche*mission. The Psyche mission currently is targeted to launch in July 2022 on a Falcon Heavy rocket from Launch Complex 39A at Cape Canaveral Air Force Station in Florida.

    The total cost for NASA to launch Psyche and the secondary payloads is approximately $117 million, which includes the launch service and other mission related costs.

    The Psyche mission will journey to a unique metal-rich asteroid, also named Psyche, which orbits the Sun between Mars and Jupiter. The asteroid is considered unique, as it appears to largely be made of the exposed nickel-iron core of an early planet – one of the building blocks of our solar system.

    Deep within rocky, terrestrial planets, including Earth, scientists infer the presence of metallic cores, but these lie unreachably far below the planet’s rocky mantles and crusts. Because we cannot see or measure Earth’s core directly, the mission to Psyche offers a unique window into the violent history of collisions and accretion that created terrestrial planets.

    The launch of Psyche will include*two secondary payloads: Escape and Plasma Acceleration and Dynamics Explorers (EscaPADE), which will study the Martian atmosphere, and Janus, which will study binary asteroids.**

    NASA’s Launch Services Program at Kennedy Space Center in Florida will manage the SpaceX launch service. The mission is led by Arizona State University. NASA’s Jet Propulsion Laboratory is responsible for the mission’s overall management, system engineering, integration, testing and mission operations. Maxar Space Solutions is providing a high-power solar electric propulsion spacecraft chassis.

    RIP Starship SN-01

    Fail early, fail often, and iterate quickly.

    Looked like the lower LOX dome let go during liquid nitrogen testing, "launching" the rest.

    SN-02 parts are waiting in the wings to be stacked with weld upgrades per an earlier post, and the SN-03 thrust structure is being built.

    Nose Cone 2 is being stacked.

    I’ve noticed these tests seem to mostly occur at night.
    I’m still going with Elon Musk is a Bond villain.

    Heh. Now I would like to see a video of the Falcon second stage separation or Starlink deploy set to Bond or Incredibles movie music (which was influenced by Bond music) from the scenes with a spacecraft in space getting ready to do something nefarious.

    They need to name the first orbital one "Trial and Error".

    As an engineer, I'd be tearing my hair out over this process. If I had hair.
