Thanks for your experience Stephen.

I see a lot of exciting milestones still to come, full orbit and daylight soft landing of Ship, double Starship launch for fuel transfer testing, Ship catching, lunar Ship details/test landing. Plus I don’t expect catching Booster to get less exciting for a while. //

Glad to see that I'm not the only one replaying flight 5 launch and catch over and over again. My wife rolled her eyes every time she sees me replaying videos of it although she was also gobsmacked the first time seeing it.

Everyday astronaut has some amazing footage. In that video you can see the exact moment the chines exploded. https://youtu.be/dpxB1S-ohEU?si=PzIO1vQhQe0XBbKn //

Slightly off topic:

Can anyone explain why so much fuel transfer on orbit is needed for the planned lunar missions? The Starship is already on orbit, after all. But I read that 10+ fuel launches are required to reach the moon. Why is that?

With the HLS' profile they likely need north of 12 tonnes of prop for every tonne of ship plus up mass from the lunar surface. We don't know how much HLS will mass, but I can't see it being much less than 70 tonnes all in, and it could be over 100. So at 840-1200+ that's a lot of prop that needs to be transferred. The HLS itself should have a good amount of residual prop (maybe upwards of 200 tonnes) eapecially if it does have full sized tanks, but you are still looking at a depot and 3-5 tankers even if you can get 200+ tonnes out of a tanker.

SpaceX wanting their proposal to be read as conservative though, assumed much less prop per launch and that they would simply brute force it. Comments that have come out of NASA since then have basically said they are carrying that forward until SpaceX proves they can do more. They'll have more performant starships and propellant transfer demonstrations launching next year, should give better certainty on the lower bound. They'll also be iterating on this. I could see an uncrewed demo mission happening in '26 possibly and '27 more probably, so that'll give them a lot of time to dial up the performance and perfect the transfer.

BOCA CHICA BEACH, Texas—I've taken some time to process what happened on the mudflats of South Texas a little more than a week ago and relived the scene in my mind countless times.

With each replay, it's still as astonishing as it was when I saw it on October 13, standing on an elevated platform less than 4 miles away. It was surreal watching SpaceX's enormous 20-story-tall Super Heavy rocket booster plummeting through the sky before being caught back at its launch pad by giant mechanical arms. //

What's not so easy to address is how SpaceX can top this. A landing on the Moon or Mars? Sure, but realistically, those milestones are years off. There's something that'll happen before then.

Sometime soon, SpaceX will try to catch a Starship back at the launch pad at the end of an orbital flight. This will be an extraordinarily difficult feat, far exceeding the challenge of catching the Super Heavy booster.

The Montana-class battleships were the pinnacle of U.S. battleship design during World War II, intended to surpass the Iowa-class with unmatched firepower and armor. Featuring twelve 16-inch guns and enhanced protection, these ships were designed to counter Japan's Yamato-class battleships and bolster U.S. naval strength in both the Atlantic and Pacific theaters.

Unfortunately, the policies Harris championed are already taking root in other parts of the country, with the same results. What's happening is devastating on so many levels, but perhaps the most devastating impact is the loss of humanity. Addicts and mentally ill people are left to their own devices, to suffer and be victimized and assaulted - and likely die - on the streets, and everyday citizens are looked at by politicians as acceptable collateral damage on the path to radical societal change. Hopefully, these stories can reach enough middle-of-the-road voters to make a difference.

The real reason men of all races are fleeing Harris’ campaign is because it's not for them—it's for women. Liberal women want their men to dress like ranchers but vote like podcasters, to LARP as masculine men until it comes to their political selves; then women want submission.

“I don’t think that this is messaging designed to convince men, but to reassure women. Like so much about the Harris campaign, it’s acting, and bad acting at that,” Ungar-Sargon said.

This assessment is spot on. In fact, even when Harris was anointed as President Joe Biden’s running mate, I pointed out that she wasn’t there to appeal to Black people, but to White women. She provided a way for female voters to support a woman and a racial minority.

If Trump’s short stint in the drive-thru window means nothing, why are all the leftists losing their minds over it?

Captain James Heise
@OvertempMarine
Jesse James was on apprentice he made a Facebook post supporting Trump, under the post, people were telling interesting story’s, an escalator installation guy, Trump bought pizza for everyone and sat and ate with everyone. But the story that stuck most with me was.

From a Limo driver, Trump used to bring vouchers for food to all the drivers waiting in the Casino parking garage, and stay and talk to the drivers, he could have any employee do that if it was just about rewarding drivers so they would bring their customers to his casino,

This driver was talking about how it was a personal touch to get to know the drivers ask about their lives and families, he’s been a huge celebrity since the early 80’s, it meant allot to this driver, enough to recount the story.

Erich Hartmann
@erichhartmann
True story: I've made a LOT of commercials, and one thing the industry gossips about is which celebrities are jerks & which aren't. Eg., Everyone loves Tom Cruise. Directors/gaffers who've worked with him says he's super gung-ho and supportive.

Also…Trump! 👇

In the mid 2000's a good buddy of mine shot a spot with The Donald, and he raved about how nice and accommodating he was. It was surprising to me at the time, because in NYC he was known as a total bastard with business deals. And based on his Playboy personality, you might expect him to be a total douche IRL. Not so, said my friend.

Then, in 2009 I was on a long business trip w/ a different friend of mine, who had worked with Trump on a different ad campaign, and he said the exact same thing: that Trump was surprisingly cool. Again, I was a bit surprised. So I asked him to give me the deets.

And this is the story he told me:

His team was booked to film Trump for one spot in a larger national campaign, and they had arranged to go to Trump Tower for a very tight window of time to film. Trump had gotten the script beforehand, too but non-actor celebrities are notoriously bad at doing their homework. Although it wasn't a complicated production, the team was nervous.

So they all went to Trump tower, pre-set up all the cameras, lights and equipment. But Trump was a few minutes late! They were very worried that they wouldn't have enough time to properly film him. Eventually, about 20 minutes past start time there was a huge flurry of activity as Trump emerged from the elevator. But instead of being harried and curt, he was upset at himself, and extremely apologetic about being late. Of course the team said "Oh, it's okay" etc, but Trump was insistent. He explained he was at a big deal that had gone long (because of some other asshole), and that he understood how valuable everyone's time was for this. And he promised to make it up to them.

Everyone was pleasantly surprised by his demeanor, and he announced to his team that he would be taking "as much time as needed" to make things right, and he xnsrudted them to push everything else in his afternoon schedule. He then proceeded to NAIL the script (because, surprisingly, he had actually practiced it), and when the director and team told him "Thanks Mr. Trump, we think we got it!" he said "Nah, we can do better!" and proceeded to do several more takes over the next hour, with ad libs and wild lines. My buddy said he was absolutely hilarious, game for anything fun, and everyone had a blast.

Then, after they had gotten all the takes they could thank of, he starts walking around the room glad handing and talking with every single one of them, person-to-person, for minutes at a time. This was way before he was even considering running for president, so this wasn't political. It was just… him.

The last point my buddy made about this was that after Trump had met all the bigwig clients, important agency people, the director and the crew, he made a point to go over and talk to the craft service guy: the lowest dude on the production totem pole, sitting there with his basket of kind bars and various gums and mints. And Trump had a super long conversation with the guy about his life, his family, and his hopes and dreams. Trump gave the kid some life advice, and then thanked everyone, apologized for being late (again), and exited the room.

To a round of applause. //

Trump can pull it off because he’s having fun. “I could do this all day. I wouldn’t mind this job. I like this job. I think I might come back and do it again,” he said. //

Everyone knows Trump’s trip to Mickey Dees was a stroke of political genius, which is why they have been melting down over it ever since the footage began going viral on social media. It may not decide the outcome of the election, but it will certainly help Trump, which is why the left-wing press is currently on a campaign to discredit the move. Desperate times do call for desperate measures, do they not?

"Put simply, the evidence obtained by the Task Force to date shows the tragic and shocking events of July 13 were preventable and should not have happened."

Those stark words are contained in a damning House Task Force report about the Butler, Pennsylvania, assassination attempt against former president and current Republican presidential nominee Donald Trump. //

The report also points to logistical issues – particularly on the part of USSS – in the hours before the rally took place. For instance, there were two command centers set up for the event, with a witness testifying that no one from the Butler Police Department was invited to the USSS’ hub. //

Roughly an hour after the local officers first noticed Crooks, the would-be assassin fired eight shots into the rally, hitting Trump and the three attendees before being killed by a Secret Service sniper. //

"To date, the Task Force has not received any evidence to suggest that message reached the former President’s USSS detail prior to shots fired," the report said.

The report also quoted a witness from the Butler County Emergency Services United (ESU) whose account of shooting Crooks appears to undercut the USSS’s assertion that one of its snipers killed the gunman.

"He fired a single shot from a standing position at Crooks, who was in a prone position on the roof. Butler ESU Witness 5 told the Task Force that he believes his shot hit Crooks," the report said.

Now, you might be asking yourself what incredible evidence the two Times "journalists" who wrote this piece came across to show that "Trump's latest allegation also appears to be false." Did they find tax records? Did they figure out what location she worked at? Did they speak to a former co-worker or manager? Did they find a mention of the job in her early resumes or writings? Nope. The entire claim that Trump is lying comes down to "the Harris campaign and a friend told us." //

As the above post mentions, Harris never said anything about working at McDonald's for her entire political career until she needed a talking point in 2019. It was also not listed on her college-era resume, where you would expect recent work history to be disclosed. In short, aside from one anonymous "friend" who suddenly decided to come forward, there is not an ounce of evidence that Harris ever worked at McDonald's.

Kamala Harris was offered an opportunity to finally work at a McDonald's restaurant but never responded to the invite, a statement circulating on social media indicates.

A franchisee on X posted what they describe as "an internal statement to the McDonald’s system from the US Senior Leadership Team" regarding Donald Trump's visit to a McDonald’s in Lancaster, Pennsylvania.

They describe the memo as "100% real." //

"Earlier today, former President Trump visited a McDonald's restaurant in Pennsylvania following a request made to our local franchisee," it reads. "As we've seen, our brand has been a fixture of conversation this election cycle. While we've not sought this, it's a testament to how much McDonald's resonates with so many Americans."

"McDonald's does not endorse candidates for elected office and that remains true in this race for the next President. We are not red or blue - we are golden." //

"Upon learning of the former President's request, we approached it through the lens of one of our core values: we open our doors to everyone," the company writes.

"It's with that same approach that franchisees have invited Vice President Harris and Governor Walz to their restaurants, in order to share how McDonald's provides meaningful pathways to economic opportunity and feeds and fosters local communities."

Speaking to a source familiar with the internal statement, they confirmed that the Harris campaign failed to respond to the invite. //

How hard would it have been to accept the invite and, based on your alleged experience having worked there, run circles around Trump? Wonder why she wouldn't jump at the chance. If she held a similar event, legacy media outlets left and right would have fawned over it. It would have disarmed Trump's line of attack. She could have even argued he was lying, not her.

But she didn't.

Elon Musk has been going all-in to stump for former President Donald Trump.

He was in Pennsylvania this weekend doing a town hall in Harrisburg. He covered a lot of topics including one not touched upon enough: that there's too much focus on a college education as a path to success. //

I think the value of a college education is somewhat overweighted. Too many people spend four years, accumulate a ton of debt and often don't have useful skills that they can apply afterwards.

I have a lot of respect for people who work with their hands and we need electricians and plumbers and carpenters and that's a lot more important than having incremental political science majors.

I think we should not have this idea that in order to be successful you need a four year college degree.//

He also spoke about the problems presented by "the Machine" that we must defeat.

Kamala is just a puppet, if the teleprompter breaks, she doesn't know what to say. I just call it "The Machine'" When the Biden puppet was not working out, they got a new puppet. It's all the same machine. It's undemocratic what was done to Biden. It's bizarre to claim Trump is a danger to democracy when what happened to Biden was entirely undemocratic. Yeah, so, it doesn't make sense. //

First, every government entity needs to have a sunset clause.

Second, Trump has got to remove "baseline budgeting" (where next year's budget is based on whether the agency spent all of last year's budget, then adds a percentage increase) and go back to zero based budgeting, where every agency budget is zeroed and they have to itemize and justify their budget needs every year.

Additionally, those budgets then have to be adjusted government-wide to fit projected revenue for the coming fiscal year. And if the projection is too high and revenue is lower, then every department gets their budgets cut proportionally to fit revenue.

That will keep them busy fighting among themselves and free up the rest of us to get on with our lives.

It will keep them fighting among themselves and free up the rest of us to get on with our lives.

So, when Vice President Kamala Harris, in an apparent bid to pad a resume heavy on the government payroll and political appointment side and light on the middle-class street cred, claimed she had "worked fries" while in college, and when various attempts to dig up any corroboration of that claim produced nothing, Trump sensed an opportunity.

Sunday, he made good on it and spent time at a Pennsylvania McDonald's learning how to cook and serve fries and bag them up to hand to drive-thru customers. The only people who seem not to be entertained by Trump's adventures in spud-making are the sourpuses on the left who've forgotten how to have a sense of humor and are incensed at the notion of a candidate staging a campaign photo op.

I say kudos to Donald McRonald on this one. Seems he found a way to turn those golden arches into a W. //

Instead of needing constant power, new system adjusts to use whatever is available. //

“Unlike reverse osmosis, electrodialysis is an electrically driven process,” Bessette says. The membranes are arranged in such a way that the water is not pushed through them but flows along them. On both sides of those membranes are positive and negative electrodes that create an electric field, which draws salt ions through the membranes and out of the water. //

The two most important parameters in electrodialysis desalination are the flow rate of the water and the power you apply to the electrodes. To make the process efficient, you need to match those two. The advantage of electrodialysis is that it can operate at different power levels. When you have more available power, you can just pump more water through the system. When you have less power, you can slow the system down by reducing the water flow rate. You’ll produce less freshwater, but you won’t break anything this way. //

On average, it desalinated around 5,000 liters of water per day—enough for a community of roughly 2,000 people.
Is 2.5L per day really enough per person when that is below the adequate intake levels according to the Institute of Medicine? Let alone for other purposes such as cooking and hygiene.

The Institute of Medicine has recommended adequate intake (AI) values for total water at levels to prevent dehydration. The AI for men aged 19+ is 3.7 liters each day, and 3 liters (13 cups) of which should be consumed as beverages. The AI for women aged 19+ is 2.7 liters about 2.2 liters (9 cups) of which should be consumed as beverages each day.

Water: An Important Part of a Healthy Winter Diet : USDA ARS
Like most other things in medicine and science there are different viewpoints on what total water intake needs to be. This study says an average minimum of 1.8 L. I've seen several textbooks that list anything from 1.5 to 2.5 L. I've also see other estimates going as high as 3.5-4 L. Age, sex, renal function, diet, and metabolic disease all have impacts on these numbers.

Hurricane Oscar developed on Saturday near Turks and Caicos, and to the northeast of Cuba, in the extreme southwestern Atlantic Ocean. As of Saturday evening, hurricane-force winds extended just 5 miles (8 km) from the center of the storm. //

Oscar was so small that its winds could not be detected by Earth-observation satellites that estimate wind speeds in tropical cyclones.

Writing in his summary of Oscar's development on Saturday afternoon, National Hurricane Center forecaster Philippe Papin noted that the hurricane was only discovered due to a last-minute flight by Air Force Hurricane Hunter aircraft.

"It is fair to say its been an unexpected day with regards to Oscar," he wrote in his 5 pm ET advisory. "After being upgraded to a tropical storm this morning, a resources-permitting Air Force Reconnaissance mission found that Oscar was much stronger than anticipated and in fact was a tiny hurricane. It is worth noting that remote sensing satellite intensity estimates are currently much lower." //

The Air Force aircraft found sustained winds, in a tiny area to be sure, of 85 mph (137 kph). Hence, Hurricane Oscar. //

Weather models struggle with the development of small hurricanes, and this is largely because the micro-physics of the smallest storms occur below the resolution of these models. Additionally, tiny hurricanes organize much more quickly and efficiently.

While we don’t know precisely what a second Trump term will look like, it’ll surely be chaotic and bleak, and could mark the end of something we certainly don’t want to lose: democracy as we know it.

That last paragraph isn't new ground. It isn't a new sermon. It has been repeated ad nauseum by the media, and Kamala Harris is getting shriller repeating it. Do people like Jong-Fast really believe their nonsense? Some do, but I think the majority of talking heads are simply in the final stages of losing their bet. They put all their money on a losing horse, and they are getting very shrill about losing. Simply, they don’t want to lose with the shame of picking the wrong horse. That their predictions of doom will never come true is what bothers them the most. In four years, they fear being collectively reminded of their "Heaven’s Gate” prediction - and that it didn’t come to pass. They also know that if Trump isn't elected, they can avoid the mockery of "I told you so". //

Media and nutty influencers are scared of one thing, and it's not a Trump presidency. Sure, they don't want to see a "President Trump", but they are mostly terrified of being wrong. Deep down, media types know that Trump isn’t going to round them up. //

Mocked relentlessly for being massively wrong is their fear. They're terrified of preaching a false religion.

Today, Politico, following on its improbable claim that Trump is eluding the media by holding rallies and cooking fries at Mcdonald's (see EPIC: Trump Trolls Kamala in Hilarious Move As He Works Fries, Drive-Thru Window at McDonald's) by claiming he has a way to seize power even if he loses on Election Day...or whenever Pennsylvania, Michigan, and Wisconsin finally get around to counting their votes: The Very Real Scenario Where Trump Loses and Takes Power Anyway - POLITICO.

In the words of Donald Rumsfeld, they start with "an illogical premise and proceeding perfectly logically to an illogical conclusion." //

So, a Trump who has less power today than he had in 2020 and in a legal environment that has foreclosed some avenues that could have been exploited last time around is more likely to try to overthrow the election results. With this assertion, Donald Trump officially has achieved Super Villain status. //

An overwhelming Harris victory would make it harder for Trump to rally Republicans to his side. (If Trump wins, no one expects a comparable effort by Democrats to subvert the election.) //

The article goes on to spin a tale that would make Tom Clancy proud. All of it is predicated on two improbable events. First and foremost, the idea that a twice-defeated Trump has enough clout in state legislatures to convince them to contravene state law and just flip the electoral votes to Trump is, bluntly, both dishonest and quite possibly stupid as well. Second, the idea that a Republican House majority that literally can't pass a single budget bill has the unity to change the rules of certifying electors requires a level of dimwittery rarely witnessed, even among political journalists.

They have no concern about Kamala Harris, who serves as the presiding officer for the joint session of Congress that will elect the president, having an unresolvable conflict of interest in both corrupting the process and outcome and engaging in shenanigans of her own. //

It's all projection. The DemoCommies just assume that their opponents are as corrupt and malicious as they are. Anything and everything they accuse Trump of, they have already done or they are planning to do themselves.

Former President Donald Trump is accusing 60 Minutes of deceitful editing of our Oct. 7 interview with Vice President Kamala Harris. That is false.

60 Minutes gave an excerpt of our interview to Face the Nation that used a longer section of her answer than that on 60 Minutes. Same question. Same answer. But a different portion of the response. //

What is written above is simply a lie. As the above transcripts show, in no way, shape, or form were the two answers the "same." Further, to call Trump a liar when he is absolutely correct about what "60 Minutes" did just shows how far gone CBS News is. That statement is not from a news organization. It's a statement from the Harris campaign, and that wasn't lost on anyone, including the Trump camp. //
