    And that's third launch of the year for SpaceX, just 24 days in.

    Yup, with another StarLink launch NET January 29.

    Time: TBD

    Methinks the term is "a blistering pace."

    Icing on the cake: the 10 Starlinks on Transporter-1 have laser satellite links

    Classic throwaway rockets are like throwaway aircraft. Small rockets are like private jet, useful if only you needs to be exactly there exactly then. A large reusable rocket rideshare is like an airliner. The latter two could coexist. Exceptions aside, the former will go extinct.
    With sufficient thrust, water towers fly just fine.

    I'm thinking the small launcher folks were not pleased by Transporter-1 going so well.

    Yes, I’ve read analyses that there is room in the market for maybe two small rocket launcher companies, but probably not three, and perhaps just one. There are companies with some interesting technology approaches, but that might end up being sold to SpaceX or someone else when they go out of business. Rocket Lab, if they get their own reusable booster working, likely could outcompete the others, except for large rocket rideshares. They already are looking like the SpaceX of small rockets.

    Speaking of launch cadence, between Transporter-1 and the next Falcon 9 launch in 4 days, they will try an SN9 test flight today.

    Basically there will be a market for those who don't want to wait for a rideshare, or who want orbits that don't fit any available rideshare. Virgin Orbit's flexibility may well give them a niche alongside Rocket Lab. I can also see one of the Chinese small sat launchers surviving simply because China won't want to use western launchers.

    SN-09

    Window: 1300 - 1900 Eastern

    Michael Baylor@nextspaceflight
    Starship SN9's testing window today lasts from 12 pm to 6 pm Central time. If the test flight occurs today, it will likely be towards the second half of that window. As always, this is testing. Schedules heavily subject to change. Teams could decide to standdown at any time.

    SpaceX Starship SN9 go for high-altitude launch attempt later today. All signs point to SpaceX’s second high-altitude Starship prototype preparing for a 12.5-kilometer (~40,000 ft) as early as Monday, January 25th in a bid to rectify a last-second bug that caused its predecessor to explode last month.

    ...while technically correct, this isn't what I'd call an accurate description.
    First, it didn't just explode, it had a hard landing due engine issues resulting from low fuel pressure. When it broke up on impact, the fuel and oxidizer did what pressurized fuel and oxidizer in the presence of flame tend to do.

    Second, this is a test program of a vehicle under rapid development. They'd be flying again even if the previous flight went perfectly. They have way more than one goal for the test, and correcting the low fuel pressure issue may not even be toward the top of the list, especially since SN9 is more of a hastily-modified twin of SN8 and later builds will probably have more permanent design changes to deal with the issue.

    StarLink

    StarLink upgrade: 10 Gbps 😎

    SpaceX director David Goldman spoke with FCC officials late last week, to discuss the company's proposal to modify lower some of the Starlink satellites to lower altitudes and give a presentation with an update on the network's progress:
    ||
    SpaceX says it plans to increase Starlink's download speeds from ~100 Mbps currently to 10 Gbps in the future.
    ||
    SpaceX dismissed Amazon's $AMZN protest of the modification as "attempts to stifle competition", saying Amazon makes "misleading claims of interference" and emphasizing that the competing Project Kuiper network represents "still nascent plans"
    ||
    SpaceX also emphasized an "ongoing commitment to space safety," saying its operations are transparent to other satellite operators, implemented automated collision avoidance, and Starlink satellites passively decay (i.e., fall out of orbit) faster due to "higher drag:"

    Boca Chica Testing

    Today: pressure testing tank SN-7.2 to failure (3mm steel, new alloy). Fill with liquid nitrogen, pressurize until it pops. Goal: see what it can take.

    Thursday or Friday: weather & rocket gods permitting, SN-09 flies.

    Is this tank design for the bottom of the first stage? Or is it a new design for the SN-xx rockets?

    It's a test tank for thinner steel with a new alloy, and whatever design changes came along with that.

    It's 3mm steel so for Starship (and Cybertruck). Super Heavy looks to be 4mm steel.

    Passed the cryo tests. Likely going to blow it to find the limits.

    OR

    Jan. 29: A SpaceX Falcon 9 rocket will launch approximately 60 satellites for SpaceX's Starlink broadband network, a mission designated Starlink 17. It will lift off from NASA's Kennedy Space Center in Florida.

    Not sure which is correct.

    I like the "approximately 60". Give or take a few. There was a time, not long ago at all, where they published a book cataloging every satellite ever launched in history. And now they don't even bother to mention the exact number in a single launch.

    SN-09

    Mary @BocaChicaGal
    Boca Chica Village residents have been asked to evacuate by 8 a.m. tomorrow. I can hardly wait to leave and watch Starship SN9 fly.
    @NASASpaceflight

    https://www.spacex.com/vehicles/starship/

    As early as Thursday, January 28, the SpaceX team will attempt a high-altitude flight test of Starship serial number 9 (SN9) – the second high-altitude suborbital flight test of a Starship prototype from our site in Cameron County, Texas. Similar to the*high-altitude flight test of Starship serial number 8 (SN8), SN9 will be powered through ascent by three Raptor engines, each shutting down in sequence prior to the vehicle reaching apogee – approximately 10 km in altitude. SN9 will perform a propellant transition to the internal header tanks, which hold landing propellant, before reorienting itself for reentry and a controlled aerodynamic descent.

    The Starship prototype will descend under active aerodynamic control, accomplished by independent movement of two forward and two aft flaps on the vehicle. All four flaps are actuated by an onboard flight computer to control Starship’s attitude during flight and enable precise landing at the intended location. SN9’s Raptor engines will then reignite as the vehicle attempts a landing flip maneuver immediately before touching down on the landing pad adjacent to the launch mount.

    A controlled aerodynamic descent with body flaps and vertical landing capability, combined with in-space refilling, are critical to landing Starship at destinations across the solar system where prepared surfaces or runways do not exist, and returning to Earth. This capability will enable a fully reusable transportation system designed to carry both crew and cargo on long-duration, interplanetary flights and help humanity return to the Moon, and travel to Mars and beyond.

    There will be a live feed of the flight test available here that will start a few minutes prior to liftoff. Given the dynamic schedule of development testing, stay tuned to our social media channels for updates as we move toward SpaceX’s second high-altitude flight test of Starship!

    Just checked a couple of live cams; there are people on a lift doing something about half-way up so nothing super imminent at the moment.

    The FAA Temporary Flight Restriction for today's SN-09 hop is still under review

    Could have something to do with range violations during the static fires. Ex: the Sheriffs missed a guy on the beach with an SUV towing a kayak trailer. He drove right past a fuelled Starship. Caught by LabPadre's stream...

    Reason for delay

    “FAA is basically giving SpaceX a hard time with the licensing because of the engine swap, it is technically a new vehicle. “

    Unlike its aircraft division, which is fine, the FAA space division has a fundamentally broken regulatory structure.

    Their rules are meant for a handful of expendable launches per year from a few government facilities. Under those rules, humanity will never get to Mars.

    If the FAA keep up that kind of attitude, I wouldn't be surprised to see a swift move abroad to a floating launch pad in international waters... Even though there is still regulations in that scenario.

    Sounds like SN-09 flies tomorrow, January 29, if the weather & rocket gods are willing. The tweet's times are Central, so add 1 hour for Eastern.

    Mary @BocaChicaGal
    I have received an ‘Alert’ notice for tomorrow and there’s a road closure scheduled from 8 a.m - 2 p.m. I have been asked to evacuate by 8 a.m. tomorrow morning. Please Starship SN9 hop tomorrow.
