    Liquid nitrogen cryotesting of SN-07.1. If they successfully completed all tests the next step should be a test to destruction, see what it can take.

    Starship FCC Special Temporary Authority (STA) for flights to 20 km (12.43 miles) from October 11, 2020 to April 11, 2021.

    This FCC permit is for telemetry, FAA will issue flight permits later. Maximum permitted altitudes are likely to increase over time.

    https://fcc.report/ELS/Space-Explora...401-EX-ST-2020

    >
    This STA uses information from previous grant 1041-EX-ST-2020 and is necessary to authorize Starship Prototype suborbital test vehicle communications for Medium Altitude Hops Tests_2 (max altitude 20km) from the Boca Chica launch pad, and the experimental recoveries following the suborbital hops. Trajectory data will be provided directly to NTIA, USAF, and NASA. Launch licensing authority is FAA Office of Commercial Space Transportation.

    SN-08 to fly to 60,000 feet (18,288 meters)

    Wow...

    aha, the real business (well it's not space yet, but...) is going to begin. Exciting times! It will also look a lot less like a flying silo with nosecone and wings added. And it will be huge.
    With sufficient thrust, water towers fly just fine.

    Now the question then becomes what are the precautions in the event of a failure? There's a lot more opportunity for SN-08 to go off course from 20km up.

    I would guess it would do something similar to what a Falcon 9 stage would, but at lower velocity, angling off towards the ocean, then probably a more or less vertical flight up and back down again, or maybe a bit of a tall loop, only angling back to land near the end if everything was going well, otherwise dropping in the ocean.

    The whole program is premised on the "belly flop" maneuver. Why wouldn't they be testing that?

    That was my guess, but we’ll see. It is “only” 11 miles up, I thought the belly flop was for reentry? In any case, hopefully it is successful.

    Musk’s Mars ambitions got a little easier. Not only have researchers in Japan found a way to make batteries cheaper, but Yasushi Sekine of Waseda University has found a way to get Methane from CO2 more easily:
    http://www.sciencedaily.com/releases...0227114523.htm

    The Journal of The Minerals, Metals & Matey Society (JOM) found a way to cold spray thin film Thermoelectric Generators (TEGs) on stainless steel so as to convert some waste heat into electricity via bismuth-telluride powder deposition.

    That could help starship as well.

    I wonder about the tiles. I imagine the tesselation needed to hold fast to a flexing tube might not be what you want. since you want to have the joins not follow straight lines that gases can follow and zipper things off—but has anyone thought of tiles that fit together one way, but have corrugation patterns on their surface that run in a different pattern?

    Has anyone thought to do that?

    They've talked about flying out over the Gulf - then, if the engines start properly, doing a divert back over land to the landing pad. If the engine start fails, it goes in the drink.

    This is the same as Falcon 9 landings at LZ-1. Falcon 9's internal map even includes surrounding structures so it can attempt to miss them if it can't make the pad. There's no reason the think Starship will be any different since it'll need this capability for landing on the Moon or Mars.

    That makes sense, I was sure they had precautions in place.

    Party Time!

    Chris B - NSF @NASASpaceflight
    SpaceX Boca Chica test schedule becoming clearer thanks to Elon. SN7.1 Test Tank, then the flagship Starship SN8 test flight to 60,000 feet - and back!

    FOUR Starships in and around the Mid Bay right now, as spotted by Mary (@BocaChicaGal).

    Not yet, but Musk will do a Starship update at Boca Chica in late October. He also hinted a flight before then.

    You know it’s Endgame when SN8 does this.

    Pretty accurate simulation, although SN8 will use 3 Raptors. If SN8 craters, SN9 & SN10 are close behind. High production rate allows for fast iteration.

    It's nuts now! SN8, 9, 10 and 11! what SN Starship do you think could reach orbit first when SpaceX begins to do orbital tests?
    |
    Elon Musk @elonmusk
    Just a guess, but probably mid teens. Booster & stacking on orbital pad are likely limiting factors. We’ll build several ships just to improve the production system.

    SN-07.1 was moved to a cheaper stand for Thursday night's test to failure (no need to do a boomski on the "good one.")

    After that the full airframe, 3 engine, SN-08 goes to the pad for a 20km/60,000 ft "skydiver" test flight - with SN-09 in the wings.

    I've missed a few videos, but as far as I know they still need to mount the wings and nose on SN-08, right?

    Unless something happened since yesterday, that's correct. One video I saw yesterday had a guy drive by and say "Hey, Mary!"

    Yup, SN-08 is a full airframe. Prop & pressure tests, static fire, post-fire checkup, another static fire, then the 20km/60,000ft hop & skydiver landing test.

    StarLink 12

    Scrubbed until 1357 Eastern tomorrow, Sept 18. Sea state impacting recovery operations.

    I think she's part of the scenery by now. I read that even Musk sometimes uses her videos to stay in the loop on progress, not sure how true that is.

    It's true. Musk keeps track of Mary's work on NSF and he watches the LabPadre streams. Mary now has a press pass via NSF..

    Today's Starlink launch also scrubbed due to severe weather in the recovery area.

    They need to give the west Atlantic weather time to clear. Peak of cyclone season.

    Well, we’re now into the Greek alphabet. If we blow through that then I guess we go with Cyrillic.

    Spacex: Acrophobics need not apply!

    Also, S/N7.1 has failed...to fail.

    Again o_O

    SN-07.1 survived the night again

    SN-08 exits the Mid-Bay with fin attachments. Image cropped,

    Day before yesterday, they had moved 5 and 6 into the incomplete high bay and three nose cones into the "tent". I assume they were expecting wind.

    I wonder what the future holds for 5 and 6. They seem to be going directly into stratospheric flight, will they not need to do any more hops?

    Stuff that bugs me: I keep forgetting to look at Mary's Twitter! And wondering "Does she never sleep?"
