Come for the politics, stay for the snark.

Just because you believe it, that doesn’t make it true.

Speaking of republicans, is there a way for a political party to declare intellectual bankruptcy?

This year has been the longest three days of putin’s life.

Thanks to your bullshit, we are now under siege.

A democracy can’t function when people can’t distinguish facts from lies.

Nothing worth doing is easy.

Nancy smash is sick of your bullshit.

T R E 4 5 O N

Wow, you are pre-disappointed. How surprising.

I wonder if trump will be tried as an adult.

If senate republicans had any shame, they’d die of it.

We’ll be taking my thoughts and prayers to the ballot box.

After roe, women are no longer free.

Black Jesus loves a paper trail.

Fuck these fucking interesting times.

Fuck the extremist election deniers. What’s money for if not for keeping them out of office?

Joe Lieberman disappointingly reemerged to remind us that he’s still alive.

Battle won, war still ongoing.

Shallow, uninformed, and lacking identity

Republicans: slavery is when you own me. freedom is when I own you.

I’d hate to be the candidate who lost to this guy.

Ah, the different things are different argument.

‘Normally, major launch sites are engineered with a trench or water system that helps to divert the rocket’s flame away from the ground and to dampen the impact […]“They didn’t do that… It appears they just went ahead and just launched this thing.”’ https://t.co/d0Qq3KmKzX

Gift (unpaywalled) link:

… Meanwhile, SpaceX’s Starship exploded minutes after liftoff and before reaching orbit. Near the launch site, the residents of Port Isabel, known for its towering lighthouse and less than 10 miles from the border with Mexico, were left to deal with the mess…

Louis Balderas, the founder of LabPadre, which films SpaceX’s launches, said that while it was common to see some debris, smoke and dust, the impact of Thursday’s liftoff was unlike anything he had ever seen.

“There were bowling ball-sized pieces of concrete that came flying out of the launchpad area,” Mr. Balderas said. The blast, he added, had created a crater that he estimated was around 25 feet deep…

Eric Roesch, an expert in environmental compliance and risk assessment who has been tracking SpaceX’s rocket launches, said in an interview that he and others had long warned of the environmental risks to the surrounding region. But without a chemical analysis of the dust and debris, he added, it was difficult to say whether or not they were harmful to human health.

But, Mr. Roesch said, “the presence of that dust kind of indicates to me that the impact modeling was inadequate, because this was not really disclosed as a possible impact.”…

— GOLIKEHELLMACHINE (@golikehellmachi) April 22, 2023

SpaceX built a slightly bigger rocket still, and on its first launch, six of its engines failed before it it exploded.

Elonistas call the explosion a remarkable success because of all the data collected.

The framing of these programs needs to align better. 2/2

    Irrespective of whatever Musk does or says, SLS is a travesty. It’s not really NASA’s fault, or at least not primarily their fault. It’s Congress, and most notably now-retired Senator Shelby, that wrote into law a requirement that SLS reuse Shuttle parts and hence Shuttle contractors, in ways that are even more expensive and hard to work with than the original Shuttle program. Yes, it flew, but at a cost of tens of billions of dollars in development money and well north of a billion per flight on top of that.

    Bet it’s in Texas not Florida because we have environmental standards. Texas tends to not, plus not enforce.

    Not sure why, but Floridians like environmental rules. I think it has to do with our water supply being so close to the surface. Easy to pollute our aquifer. Plus tourism. Also we are a big agriculture and fishing state even though most people don’t seem to know that.
    We have had some pollution issues from companies but I suspect a new to the state company would find it harder to get away with it and it is against the rules.

    Pics of the uh…degraded launchpad indicate a complete rebuild.

    I thought they had done static tests of this thing, but maybe horizontal. There was that one which just blew the hell up sitting on the ground, after some fueling test or other. Maybe that was Spaceship sans booster. I can’t keep track.

    NASA built the largest rocket in history. On its first launch it delivered an unmanned crew capsule around the Moon and back to the Earth as designed. NASA didn’t consider the test successful because the capsule suffered unexpected damage.

    A friend who was working at the Software Engineering Institute at Carnegie Mellon once told me that software for the space shuttle cost ten times as much to develop as equivalent commercial software, because of the procedures in place to ensure correctness, safety, etc.

    When you set out to spend an order of magnitude less than known costs for a successful operation, expect failures.

    That’s on the science and engineering side.  On the social side, this is unconscionable.  I can imagine that some years from now we might see an uptick in lung diseases in this town, but there will be no way for a specific patient to pin their condition on this specific event, even if it were the true cause.

    @Gvg: Bet it’s in Texas not Florida because we have environmental standards.

    Quite possibly a factor, but from what I’ve read, it’s mostly because Musk wanted to shuffle personnel between the launch site and his own base in California on short notice.  Florida was just too far away for that, and he’s a hands-on manager, when it comes to interfering with the people who might know what they’re doing.

    Hydrazine. Nasty stuff.

    Titan II missiles were based in silos around Tucson, Arizona.

    Around 1970 (maybe after) I was able to participate in a tour of an operational silo.

    Part of the underground complex included showers and eyewash fountains for maintenance crews. Fueling, if I recall correctly, was carried out by maintenance crews in sealed suits that resembled space suits.

    When you entered the silo proper on the tour you were issued a gas mask in a satchel. They implied that if there was a fuel leak we’d be in serious trouble anyway, but the gas mask was supposed to make you feel a little better about it.

    You’ll want to read this entire thread. The author is an aerospace engineer. He explains not only the launchpad problems, but also, in response to questions, why the design of the rocket itself is flawed. Largely because it is based on a design and engineering failure of a rocket that the Soviet’s tried and had to abandon.

    This is what happens to your launchpad when you think it would be funny to launch to the world's largest rocket on 4/20, instead of when it's ready.It will probably be at least a year before the FAA will approve another Starship launch. pic.twitter.com/tXytW309a6— Christopher David (@Tazerface16) April 21, 2023

    @prostratedragon:

    The warhead was interesting. The operational crew members would specifically not acknowledge it was a nuke. As if any of us were really wondering.

    The operational (alert) crew members carried sidearms.

    I stood on a temporary maintenance platform (metal grate, folded down from the wall, by an access door) near the bottom of the silo, next to the engines. The crew member placed his hands against the side of the missile body and gave it a shove to demonstrate the spring mounts.

    If I recall correctly, water at the bottom of the silo was part of the launch process. Since the silos were effectively single use I’m assuming it was for vibration and heat attenuation rather than protecting the silo.

    Whatever the fate of Starship, that launch tower (and probably Boca Chica as a launch site) is/are fucked. It needs a flame trench (and deluge/noise suppression system), but you can’t dig one there; it’s three feet above the water table, due to being at the coast. So you have to do like NASA at Canaveral and build a hill.

    Which requires tearing down their launch stand and tower. So SpaceX didn’t just blow up Starship, they also blew up their multi-million dollar tower, chopsticks and all.

    @Baud: Yeah.

    I was very surprised how long it sat on the pad with the engines running.  (No time to look at the video again, but) It seemed to start the engines before zero (as usual), then sat on the pad for a LONG time (5-10s?) before actually crawling up into the sky.  That’s a lot of force very close to the ground for a very long time, of course it’s going to kick up a hurricane of dust unless they control it.

    If that’s the way the thing is going to run, the EPA, FAA, etc., needs to come down like a ton of bricks on Melon and say that no more launches are allowed until they fix their blast containment issues.

    Enough fine dust can be deadly no matter what is in it.  I’m sure most here remember the claims that the dust in NYC was no big deal in 2001…

    I just remembered.

    One of the issues with making rockets bigger and more powerful is that they become noisier. On the outside, but also on the inside.

    Artemis 1 was 136 dB 1 mile from the pad:

    NASA engineers anticipated that SLS’s launch would be loud, so they dumped 450,000 gallons of water onto the launch pad to help dampen the sound. Even with the water, however, SLS produced noise levels that were higher than those NASA had predicted in a preliminary assessment. The noise roughly three miles from the launch site, for instance, was nearly 20 decibels higher than expected.

    “This suggests a need to revisit and probably revise those [noise prediction] models,” says co-author Grant Hart, a rocket noise researcher at BYU, in the statement.

    These models are important because rocket launch acoustics—particularly the vibrations caused by all that noise—can damage items and systems onboard the spacecraft.

    “If you don’t understand the acoustics produced by the rocket, you can’t design payloads efficiently,” Gee told Popular Science.

    Here’s hoping that Melon’s astronauts have good noise-canceling headphones, but their internal organs might want noise canceling stuff too…

    It’s easy to ignore real-world constraints that exist for a reason, but there are real-world consequences to Leroy Jenkins-ing that Melon still hasn’t recognized yet.

    Grr…,
    Scott.

    @different-church-lady:

    only 75% of the engines ignited, 25% failed in two clusters, both on the outer edge, about 50 degrees apart from each other, so unequal thrust on the edges, that’s what caused the shakes and early spin.

    That’s probably the root cause of the failure.

    The fact that the lift off destroyed the Mickey Mouse launch pad and scatter debris across miles, is just “chef’s kiss”.

    @different-church-lady:

    if the failed engines had ignited on the launch pad, then encountered debris, the Starship would have rapidly experienced unplanned disassembly on the launch pad.

    That was the key problem the Soviets and many other had. It’s hard enough to get three or four rocket engines to all ignite at exactly the same time, let alone 30. It’s why most ICBM and Ballistic missiles use a single, multi stage system, less chance of failure, less chance of the missile taking an unplanned trajectory.

    @Michael Bersin:

    If I recall correctly, water at the bottom of the silo was part of the launch process. Since the silos were effectively single use I’m assuming it was for vibration and heat attenuation rather than protecting the silo.

    According to Dr. Phil Metzger (formerly of NASA) in this Twitter thread, the water is entirely to dissipate acoustic energy (the initial shockwave from the rockets igniting and the steadier noise afterward) and prevent it from damaging the rocket. The flame trench is to dissipate heat.

    This launchpad was apparently a steel plate with no flame trench or water system, which they apparently thought the rocket could handle. Dr. Phil doesn’t seem as down on it as t would expect, but it seems dumb to me. You get a cheaper and simpler launchpad, but you lose payload capacity by designing the rocket to stand up to the extra vibration and stress.

    He overrode his Tesla engineers when they told him he couldn’t build a fully automated assembly line, which resulted in cost overruns and months-long production delays.

    He overrode his Tesla engineers when they told him they needed the radar sensors in order to develop his autopilot system, leaving him a system that uses cameras only, something that no one else in this space is doing. As a result, his autopilot dream continues to recede farther and farther away.

    He overrode his Twitter engineers on … well, pretty much everything, which resulted in a platform that is increasingly unstable, with massive increases in hate speech, trolling, spams, and scams, which is also resulting in his advertisers dramatically reducing their investments there.

    He overrode his SpaceX engineers when they told him he needed flame diverters on the Starship launchpad, which resulted in a destroyed launchpad and very likely contributed to a failed launch.

    No, Orion does not make tons of deadly radioactive fallout. If you launch from an armor plated pad covered in graphite there will be zero fallout. And No, it would not create the apocalyptic horror of EMP making the world’s cell phones explode and wiping out the Internet. That’s only a problem with one megaton nukes, the Orion’s charges are only a few kilotons. Just launch from near the North Pole (at least 276 kilometers from anything electronic) and you’ll be fine.

    @Edmund dantes: My family is from Texas City and Freeport. Both are refinery central. Dad remembered the explosion in 1945, as he was 9. That leveled a huge chunk of the city. I remember the one from 1980, I think. Smaller, but I still recall being woken up by the boom. My older brother survived the explosion in the 2000s at the plant he then worked at. He had just happened to step into a fresh “bombproof” building at the time, luckily.

    420 refers to marijuana. The term originated with some high school students in Marin County, north of SF, who regularly got together at 4:20 p.m. after school to smoke it. From there it spread as way to talk about pot without teachers catching on. The students had connections to the Grateful Dead, and were backstage at the Dead’s concerts, where the phrase spread to Deadheads, eventually being discovered by a reporter for “High Times” magazine, which did a story on it, and the phrase went worldwide. April 20th is now an international day celebrated by weed connoisseurs — of which Elon is one.

    Uncle Cosmo

    April 23, 2023 at 11:32 am

    Late to the thread, but here goes:

    @gene108: The USSR tried a 30 rocket design, but could never get it to work.

    Yup. Over 50 years ago. Using Soviet computational and control systems. With hypergolic propellants (UDMH and NTO if memory serves).

    Considering the massive advances in automation, real-time data collection and feedback in the intervening decades, there is some reason to think the art and science of multiple-engine control might just have advanced a mite since then.

    (Let’s clear up one issue before proceeding: The “launching on 4/20” yammer is just that, yammer. First try was on April 17 – scrubbed due to pressurization issues. Next chance was the 20th. No reason [other than personal animus] to think Lone Skum was hot to launch on the former Schiklgruber’s birthdate – he was just hot to launch, full stop.)

    Just FTR, the multi-engine idea wasn’t original with the USSR either: Here is a Von Braun 3-stage-to-orbit concept from 1952 with 51(!) engines in the first stage (and 22 in the second) burning hydrazine and nitric acid. The Soviet N-1 moon rocket (that Christopher David seems to believe, mistakenly, SpaceX got the idea from) was a lot closer to this than is Starship/Superheavy with its methalox propellants.** In fact the Russian Soyuz gets a lot of generally-reliable mileage out of the old R-7 Semyorka ICBM design that featured 16 first-stage engines in pods of 4 burning kerosene and LOX at liftoff.

    * * *

    Now then: Can we wait for thorough failure analysis before snickering? At the moment it seems quite possible that the multiple engine failures at liftoff (6 of 33 IIRC) were caused, not by anything inherently flawed in the vehicle configuration, but by debris blasted up into the booster engine compartment when the supposedly extremely resistant (obviously not resistant enough!) concrete of the launch pad shattered under 17 million pounds of thrust.

    Even so, the 24/7 stack made it to 40 km altitude, where the brand-new and untested passive stage separation technique failed when the assemblage started tumbling out of control. The loss of multiple engines likely contributed to that, if it wasn’t the root cause. But we shall see.

    Clearly SpaceX needs to fix Stage Zero (the launch facilities) before another launch – flame diverter and serious water deluge at a minimum. High water table at Boca Chica may make that ruinously expensive if not impossible. Lone Skum tweeted they were a couple of months away from installing a diverter but in the eagerness to get the bird off…

    Now everyone knows that was a mistake. It’ll be interesting to see what they come up with. Maybe they’ll need to revisit the concept of seaborne launch platforms (which of course will have their own issues)…

    ** My guess is WvB’s conceptual engines were about as powerful as those of the A-4, roughly SotA at the time, for a total of ~3 million pounds of thrust on liftoff. No one tried to build much bigger engines until the F-1 (~1.5 million pounds of thrust) – and getting those monsters to work reliably was a (and may have been the) major headache of the Saturn program.

  118. 118.

    The Orbital Launch Mount (OLM) at Boca Chica was a disaster waiting to happen but the Heavy booster design isn’t that bad even with thirty-three Raptor 2 engines shoehorned into the bottom. The world of engineering has moved on from the time when the Soviet N1 was designed and built and the SpaceX Raptor 2 engines are quite good and reliable bits of kit.

    One issue with the OLM is that it’s actually coupled to the outer ring of twenty Raptor 2 engines at the base of the Heavy booster to provide turbine startup gas for the twenty rocket motor pumps. All other boosters carry bottled gas to spin up the turbines for their rocket engines and the Heavy actually carries gas for the thirteen central Raptor 2 engines since some of them will need to be restarted to land the Heavy booster after separation from the Starship upper stage. The problem is that if one or more of the OLM connection adaptors doesn’t work that motor can’t start – in what SpaceX calls “spin prime” cold start tests they’ve never successfully got all thirty-three engines to spin up at the same time and it’s always been one or more of the outer twenty engines that fail to start. It looks like they only got 31 motors spun up for this launch. It might have been why it took so long to take off after ignition, the launch controllers were maybe hoping the two lagging motors would fire up if they waited a few seconds with the other motors running at reduced thrust.

    Bad things were visibly happening in flight even when the Starship Heavy had cleared the pad — plumes of leaking methane burning orange was seen coming from within the engine cluster followed by more engines shutting down, probably due to accumulated damage from the takeoff. The total thrust expected was way down on what it should have been, after most of the Heavy section’s propellant had been expended it was travelling a lot slower than it should have been and it never reached the correct altitude and velocity for separation. My guess is that the flight control system had to spend too much time and propellant correcting the unbalanced thrust from the failed engines and not enough delta vee was left to push the stack on its planned trajectory, but that’s only my guess. SpaceX is a closely-held corporation and they are very secretive so I don’t expect any real data from that “test flight” to be made public. NASA, on the other hand, holds a press conference every time someone drops a spanner but they have to since they’re a public organisation.
