    SpaceX may resume Starship testing on Thursday with a road closure scheduled between 9 am and 6 pm Central time. Unclear if this testing will be for SN7.2 or SN10.

    According to a SpaceX security officer we spoke to today who was overseeing the cleanup, SN10 sustained no damage. They intend to push for launch within the next 1-2 weeks! So my money is definitely on SN10 😳 🚀

    I know it seems to defeat the purpose, but maybe a type of straightening chute just to get one down safely for inspection? Small cameras all in lines and tanks to see how things slosh about. Maybe a reinforced winged flyback to abuse? Oh, could you post a pic or three on the SLSS concept art? I can't get a print off NSF. That, the upper stage collection depot and perhaps a Cygnus-like Dragon-XL next to it for scale...docking.

    Feb. 4 (ALREADY LAUNCHED) : A SpaceX Falcon 9 rocket will launch approximately 60 satellites for SpaceX's Starlink broadband network in a mission designated Starlink 18. It will lift off from Cape Canaveral Space Force Station in Florida, at 1:19 a.m. EST (0619 GMT).

    Feb. 5: 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, at 5:14 a.m. EST (1014 GMT).

    === UPDATE

    SpaceX successfully launched another set of Starlink satellites Feb. 4 in the first of back-to-back Falcon 9 launches scheduled from Cape Canaveral. The Falcon 9 rocket lifted off at 1:19 a.m. Eastern from Space Launch Complex 40 at Cape Canaveral Space Force Station. Its payload of 60 Starlink satellites separated from the rocket’s upper stage 65 minutes later.

    Tests today. Pad is clear.

    Either cryo-testing SN-10 or popping the 3mm steel SN-7.2 test tank to see what it can take.

    Scott Manley has his evaluation of the SN9 test.

    I thought it was a good analysis, but I'm not a rocket scientist. He thinks it was a different failure mode than SN8; probably a bad engine, and not problems with fuel flow.

    SN-7.2 popped, as was the goal. Needed to see how much pressure 3mm steel can take.

    Starlink 17 and 18 were out of order.*

    Looking like a GO for SN-10 soon

    Everyday Astronaut@Erdayastronaut
    Of course, @SpaceX isn't "dumb" as @elonmusk joked, but they definitely are trying to bite off a lot with these early test flights and there's certainly room for improvement. We'll go over how we'll likely see this maneuver evolve and what upgrades we'll see in the future.

    I'm nothing more than located in the comfy armchair on this, but I too thought "maybe you should light up all three and shut the least loved one down if the other two look good". The static fires indicate they can spot a good burn incredibly fast anyway.
    With sufficient thrust, water towers fly just fine.

    It's not like they didn't think about it, it's why they added the third engine in the first place...earlier concepts only had two. But it's more complex to do that, and wouldn't have helped SN8, since it's only useful for a problem internal to one of the engines.

    I'm guessing SN9 turned out to be one such problem, hence them feeling foolish now. They knew how to handle losing an engine, had the hardware needed to do so, but thought they could get away without it for now.

    Looking at post 4330. Wow, Musk sure stayed away from Twitter for a long time. (Looks like he was posting around midday Thursday.) Did he even manage 24 hours? He’s addicted.

    There are people Musk follows and usually replies to and Tim Dodd (Everyday Astronaut) is on that list.

    SpaceX to launch NASA astrophysics mission. NASA awarded a contract to SpaceX for the launch of the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) spacecraft on a Falcon 9 in June 2024. The value of the launch contract is $98.8 million, which includes the launch itself and other “mission-related costs,” the agency said.

    The SN-08 FAA license violation was a "miscommunication,"

    Christian Davenport @wapodavenport (Washington Post)

    Some Congressional staffers were briefed *yesterday* on the SpaceX FAA launch license violation. They were told there was a miscommunication on modeling for how far any shockwave would travel from a blast and the damage it would cause--ie broken windows--in changing weather.
    |
    Given the communication problem, FAA investigated not only the SN8 hard landing but also did "a comprehensive review of the company’s safety culture, operational decision-making and process discipline." The investigation was done quickly and changes were incorporated for SN9.

    Op-ed | The FAA and SpaceX. Today, the fate of the SpaceX Starship offers an example of how government oversight agencies can stifle innovation when they are unable to distinguish between innovation and execution and throw roadblocks in front of the single company that has transformed access to space.

    https://spacenews.com/op-ed-the-faa-and-spacex/

    I do not personally agree with this opinion, just saw it as interesting for discussion.

    Okay, but that isn’t taking a break from twitter. It doesn’t matter to me, I just think it is funny that he said he was taking a break from Twitter and went right back to posting on twitter.

    He was away from Twitter for a full day! Both the daytime AND nighttime! It's something...

    Regarding the FAA overviewing SN9 going kaboom: I can't have an opinion on that before knowing if, for how long, and under which conditions IF ANY they would restrict/delay future tests.

    From what I've heard before, kaboom itself is not a problem for FAA as long as they've covered the risk involved in case of kaboom.

    My impression was that there was only a very short delay due to this incident. It seems to me the FAA had a very rapid review process in this case, so I can’t get too concerned about it. If the FAA had delayed them for a couple months for review, I would be much more open to arguments the FAA was putting roadblocks in front of them. Or if they get more obstructive during future development I could easily see more to this argument.

    I was posting the same time you were. Yes, that’s pretty much my view as well. This wasn’t much of a delay, it remains to be seen what they do if/when future tests have their own anomalies.

    I think we're being dragged along by Musk's impatience and constant Tweeting. The FAA was doing fine, so far as I am aware.

    In the end things did indeed seem to go fast. Some miscommunication here and there apparently.

    I can imagine the FAA will need to be involved if they'll want to allow tests with such a high chance of explosion in the future. Starship not only looks like a fifties rocket, it also explodes like one. So I say, if SpaceX and FAA find a way together to allow for safe testing of very unproven, RUD-inducing technology at a rapid pace, none involved can complain.

    Another thing to watch is the FAA-AST licensing rules change in a few weeks, moving to a more relaxed and quicker permitting system pushed by the commercial operators.

    I watched the 7.2 pressure test video. I still haven't figured out the trebuchet in the foreground. Googling got me something about "Raptors Roost" but but no further.

    Hans Koenigsmann, SpaceX's Vice President of Mission Assurance, is retiring. Off to annoy fish.

    Taking over the reins will be former NASA Associate Administrator for Human Exploration and Operations William "Bill" Gerstenmaier.

    SpaceX is a monster of production

    Can you imagine how the SLS team feels watching this?

    Rocket blows up, its replacement is already built, 2 days later its 2nd replacement is nearing completion.

    A rocket a week or two is an unimaginable flex.
