Comment With Trump president? (Score 0, Troll) 42

Our intelligence agencies are going to be leaking like a sieve. The last time Trump was President the number of captured and killed intelligence assets skyrocketed. I haven't been monitoring at this time but I'm sure it's shot up again. Never mind the fact that we found out Trump was taking classified documents related to his businesses.

What pisses me off is the Democrats kept putting Republicans in charge of prosecuting Trump because they were so desperate to appear unbiased. Fuck that shit look where it got us. Tons of dead soldiers and we are probably going to put boots on the ground and do a draft soon. Because Iran isn't Iraq. We do not have the troops to occupy Iran. That's based on the pentagon's own math and that math is well tested and well understood.

Not that it matters to any of the old farts around here. None of us are going to get drafted and we know it.

Comment Re:"have left Earth orbit" ?! (Score 1) 76

Pardon? Have you not seen the barge landings?

There are many aspects of a flight profile. Some are based on where you put the payload when it is in orbit. Others are the weight of the payload. As an example, 9's Payload for a GTO orbit is 5.5t when recovered on barge, and 8.3t for an expended mission. LEO orbit, 17.5 t if recovered, 22.8t expendable.

Just because some flight profiles can land at a pad or on a barge, does not mean that this happens in all cases.

A pretty good read if you have the academic credentials to access it. Clear, at a reasonably high level so not too deep in the weeds, with all manner of different flight profiles for many rockets - including StarShip. And a lot more. Otherwise, I think it is a little premature to claim the success of Starship. The Falcon's are good reliable Rockets. Starship might end up a tad problematic.

Robots are coming no matter what. There's no accelerating it anymore than it can be. The ruling class, the Epstein class is tired of being dependent on employees and they don't give a rats buttered behind what it costs. The only thing stopping them from automating everything is they haven't quite worked out how to do it yet. Cost is not a factor anymore. They don't want you. They don't want you as a consumer and they especially don't want you as an employee.

The Old Kings had a Divine right. The Epstein class wants that back.

Your assignment: Find out why reusable rockets are only useable for very specific launch envelopes. If you use them out of that launch envelope, there are just as disposable as the rockets you think are some sort of complete waste.

Interesting. I've never seen this claim made before; do you have a reference?

https://www.teslarati.com/spac... Forgive the link, it is a real rah-rah piece.

CEO Elon Musk says SpaceX has successfully expanded the envelope of orbital-class rocket recovery with its 50th booster landing, meaning that all Falcon boosters will have a better chance of safely returning to Earth from now on.

https://space-offshore.com/boo... "Falcon 9 missions may need to land on a droneship instead of RTLS due to the weight of the payload or the overall mission profile." I think you have academic access. Here is a good technical report on a lot of rockets that land after use. https://www.sciencedirect.com/.... You'll need academic credentials to download it. But it has a lot more info - and as part of the launch envelopes, there is constraint based on payload as well as direction. If you are going to land, there is a significant reduction in payload.

All of this is why I find it a little amusing that many among us find the most important aspect of launching these candles is the recovery.

tl,dr - where the rocket is going, what it is carrying has a big effect on recoverability. You can force things, reducing payload, or only sending the profiles to places where the first stage can make it back to the launch site, otherwise small extensions to allow it to make it back to a barge.

Municipalities will just pass laws or constitutional amendments to get around the robot problem. If they have to they will sneak it past voters during a special election or a midterm with a bunch of scary propaganda. If all else really fails and they can't ram it through with the current legislative framework they will just change the laws and/or pack the courts.

America is a borderline lawless country where might makes right and money is all that matters. We are one bad election away from just straight up Soviet style government. We let the top have too much money. The last election Elon Musk didn't like the way it was going and he just casually dropped a quarter billion dollars on his preferred candidate. You just can't deal with that.

Comment It's a tax on working people and the poor (Score -1) 163

If you pay attention to where they put these it's always in poor neighborhoods. You never see them in the rich neighborhoods because if they put them there well to do people have the time to lobby and get them removed or made illegal.

But rich people also don't like paying taxes. But they do like having services. So they find ways, like speeding cameras, to make sure that poor people pay through the nose so they don't have to.

It's the same way for the suburbs. Seriously Google it. The suburbs are completely unsustainable without the high population density inner City even though the inner cities are typically full of poor people. Middle class and well to do people leave the inner cities to poverty but they extract money from them. Because of the much higher population density they can get away with that.

It's going to be fun in a few years because we're gradually collapsing the entire economy and the suburbs are going to go with it. They cannot without subsidies afford their roads and police and fire departments and schools and whatnot. Even with the higher incomes they just don't have the population density for it.

And it's going to get real as the tax base collapses and we can't afford police anymore. You are already seeing some of the smaller towns and cities having to shut down their police and sheriffs because they're just isn't enough money and the smaller towns full of poor rural folk don't get to pick the pockets of the inner city the same way.

"Ladies and gentlemen, I am so, so excited to be able to tell you that for the first time since 1972 during Apollo 17, human beings have left Earth orbit," NASA's Dr Lori Glaze

I can expect some random science reporter to make this mistake, but bugger me, a senior NASA executive? It shows politics are far more important than any knowledge of science at NASA today.

Not only is Orion not leaving Earth Orbit (where the fuck do they think the moon is?) , it is not even entering lunar orbit. Orion's apogee has been pushed up for one orbit, but it's perigee is right down here.

Because Orbital mechanics is pretty difficult for most to grok. She does have bona fides, Doctorate in Environmental Science and Masters in Physics.

So I'm pretty certain that she well knows that Orion is still in orbit around the earth.

But just think about it. We have people in here who think that not re-using a rocket is some sort of crime, not thinking how that first stage can only return if it is close enough to the launch site. That if you want to go to the moon or a planet, you just point your Rocket at it and it's balls to the wall time. Among other misguided notions.

All said, She is an administrator, and I believe her excitement when she said that, so I'm not quite so willing to call her a political appointee. I'd call it an audio typo.

If it was me, I might say it was the first time humans have left Low Earth Orbit since 1972. And since it is a matter of providing soundbites, I would save the Perigee and Apogee part for later. Perigee and apogee are the more interesting parts from my perspective.

The learning curve is why. I can't imagine there is anyone from the Apollo project left at NASA. So a whole new group of people have to learn how to make things work. All those people sitting at their consoles are learning, re-learning after a fashion, what the Engineers learned in the 1960's.

Yeah, it was cool watching those four $146,000,000/each RS-25 engines return to the landing pad. Stupid capitalists.

A lot of people have a lot of trouble understanding that returning a first stage to the launch site puts a huge constraint on where in orbit you can place that rocket's payload.

You can add a bit of flexibility if you return a rocket to a barge in the ocean - but not much. And when you use a barge, you are eating hard into whatever savings there are in capture and refurb.

The first stage has to have enough fuel to make it back to the landing pad or barge. If the launch envelope takes it out of that range, it's just another disposable rocket. As an indicator, people will notice I only mentioned the first stage. Because there's no good way to recover the second. The rocket is way too far downrange, the earth is rotating. There aren't many landing sites at that point.

But what I think is really going on is dodgy attorneys have been putting fake citations in their briefings for centuries and we are hearing about it because they're using AI to generate the fake citations instead of just making them up on the spot like they used to. I suspect judges and defense attorneys are scrutinizing citations more too because they've seen the stories about AI.

But I do think it would be naive to believe that given how skeezy attorneys can be that they haven't been feeling their portfilings with bullshit long before AI slop was a thing
