@elonmusk Hey Elon, does R3 provide dry O2 for autogenous pressure and eliminate ice issues in the O2 tank?

Getting closer to Starship launch! 🚀

@DARmamabear @cydelmg @elonmusk @OPteemyst Non-Player Charactor... an "extra" in a video game scene.

@cydelmg @elonmusk @OPteemyst What is an NPC, plz

@hydrocephology @VigilantFox 6 55-gallon drums.

@VigilantFox 33 zero gallons! Weird. I wonder if it’s scripted and meant to be talked about.

JOE ROGAN: “One of the creepier things about the Epstein Files was that he ordered 330 gallons of sulfuric acid after he’d been indicted.” MATT MCCUSKER: “What’s that do?” ROGAN: “Dissolves bodies.” [McCusker grimaces] ROGAN: “Yeah. They were trying to speculate that maybe that was for his desalination system that he had… some sulfuric acid cleans it out. But then Jamie looked into it. He had only ordered it like once before, ever, but never that much.”

@niccruzpatane !!

Here’s what happens when a couple of Waymo vehicles meet on a narrow street:

@EmpireEnjoyer3 @HealthRanger The Moon is a Harsh Mistress... make SciFi real.

It’s not a fairytale. Human space flight was a fairytale once yet here we are. We are going to the moon for both economic prosperity and to make it a weapon. Always some half baked takes on this site. The moon is full of water, ice, which via electrolysis can be turned into rocket fuel, water, and breathable oxygen. There is a scientific and economic case for the Moon right there, not to mention Starship has low pound to orbit costs, which will bring human demand to visit the moon. There’s also no regulations on the moon.

An object free-falling from the moon's to Earth arrives at around Mach 32, give or take. That produces near-nuclear-like kinetic damage on ground targets, with deep penetration capabilities, without using nuclear weapons. The Moon is the high ground. Earth sits at the bottom of a gravity well. Launching weapons from the high ground requires very little thrust, since gravity does all the work. This is why Elon has now been tasked with selling the fairy tale that we're going to build "human cities" on the Moon. No we're not. That's a fairy tale for simple-minded morons who are scientifically illiterate. In reality, the USA is going to be building weapons platforms on the moon, from which America will threaten every nation and every person on the planet. Basically, Elon has been tasked with selling the "moon cities" fairy tale to the public while the DoD actually turns the moon into the DEATH STAR. Because the U.S. government is run by murderous lunatics, and they want absolute military dominance in space, obviously. I'll have full details in my report tomorrow.

@Americanus63136 @aakashgupta If so, build spin gravity habitats.

@aakashgupta "What years of 1/6 gravity do to human bone density and cardiovascular systems is completely unknown." It's known lol you'll just die. Cells will cease to properly function. Nonetheless, we must get to the Moon and further.

A city on the Moon will cost somewhere between $100B and $500B, require thousands of Starship flights, and demand a decade of nonstop construction in a place where the temperature swings 400°C between day and night, the dust cuts through metal seals like sandpaper, and a single cracked habitat window means everyone inside is dead in about 90 seconds. Musk just announced SpaceX is doing it anyway. Here’s the actual engineering path. You build at the south pole. Specifically the rims and floors of craters like Shackleton and Cabeus, where temperatures in permanent shadow drop below -230°C. NASA estimates 600 million metric tons of water ice are buried in these craters under about 40 cm of dry regolith. That water becomes your oxygen supply, your drinking water, your radiation shielding, and 78% of your rocket propellant by mass. The crater rims get near-continuous sunlight for solar power. You build where the resources are. Getting there is where it gets wild. Every Starship lunar mission requires 10-15 tanker flights to fill 1,200 tons of propellant in Earth orbit before the ship can even leave. One cargo delivery to the lunar surface burns through roughly 12 Starship launches. Starship V3 lands 100 metric tons per trip. The Moon is 2 days away with launch windows every 10 days. Mars gets one window every 26 months with a 6-month flight. That 13x iteration advantage is why Musk pivoted. The first 20-30 landings are all cargo. No humans. You’re sending solar arrays for the crater rims targeting 100+ kW continuous, nuclear fission reactors for the 14-day lunar night, ISRU rigs that mine ice from regolith and electrolyze it into hydrogen and oxygen, pressurized hab modules, and autonomous rovers that 3D-print structures from lunar soil using concentrated solar heat. Each landed Starship also stays as a permanent building. 50 meters tall, 9 meters wide, 1,100 cubic meters of pressurized volume. The ISS has 916 cubic meters and took 13 years to assemble. Three Starships on the surface already exceed that. The economics flip the moment you start producing oxygen on the Moon. You stop shipping 78% of your propellant from Earth. Tanker flights per mission drop from 15 to about 4. Every ton produced locally frees up mass budget on the next inbound Starship for more construction equipment, food systems, and mining hardware. The base starts building the base. That’s what “self-growing” means. Compound logistics where each delivery makes the next delivery cheaper. 2027: first uncrewed Starship lunar landing. SpaceX told investors March 2027. 2028-2030: cargo buildup, 30-50 deliveries, all robotic, ISRU prototypes go operational. 2030-2032: first crews arrive, probably 6-12 people, 6-month rotations, running equipment maintenance and scaling propellant production. 2033-2035: permanent population hits 50-100, propellant depot goes up in low lunar orbit so arriving ships refuel before descent. 2035 onward: population grows past 100, agricultural modules come online, the base becomes partially self-sustaining. The unsolved problems are real. Lunar dust is electrostatically charged and sharp as broken glass. It shreds seals, clogs machinery, and embeds in lung tissue. Nobody has a long-duration fix. Radiation on the surface runs 200x Earth’s dose. Regolith shelters and water shielding help but add enormous construction overhead. The 14-day night drops temperatures to -173°C and kills all solar power, and the only flight-ready nuclear reactors produce 1-10 kW, far below what a growing base demands. What years of 1/6 gravity do to human bone density and cardiovascular systems is completely unknown. SpaceX is valued at a trillion dollars and just told investors the Moon comes first. They’re betting that proving lunar logistics at commercial cadence builds the playbook for Mars. The Moon is a 2-day test lab with a 12-day resupply cycle. Mars is a 6-month voyage with a 2.5-year wait if anything breaks. It makes sense.

@engine_rich @JK_Lundblad @tomaspueyo Don't bet against Elon and his hard-core tech teams.

Thank you for this honest reflection. It seems many have forgotten that only a short 10 years ago, Starlink was understandably thought to be absolutely insane and impossible. It surprisingly became even more ambitious and successful than what was originally proposed by SpaceX in 2016. How quickly we forget that the vast majority of observers, including experts and extremely smart individuals, thought that Starlink could not possibly succeed.

I don’t think people understand the merger of SpaceX and xAI SpaceX has a massive pbm: it’s creating so much capacity to ship stuff to space that humanity doesn’t know what to do with it That’s why SpaceX launched Starlink: It decided to be its own customer and fill the rockets with comms satellites xAI has a massive pbm: It needs to massively scale its AI investment to compete with the biggest labs, but it came late so it doesn’t have the revenue, and also scaling is harder and more expensive every day. By joining the 2 companies: 1. SpaceX gets tons of stuff to send to space (data centers plus solar panels) 2. xAI gets funding to continue investing in AI (funded by Starlink revenue plus whatever the merged company gets from public markets 3. xAI gets (allegedly) a huge advantage in building AI, because it unshackles it from permitting new energy facilities on the ground The hope is this allows xAI to reach AGI before others, and this creates another massive revenue stream for SpaceX. It’s basically replicating the playbook of Starlink, except much riskier.

@Object_Zero_ @Obserfessor The power grid is sized for maximum daytime load. All that capacity is throttled way back at night, when adjustable rates are low. EV's and bots can charge at night with minimal impact to the grid.

@Obserfessor Where does this night energy come from? We are energy constrained.

Genuine Question… If Elon is going to space to power AI, what is going to power the 1bn Optimus robots and 20m Robotaxis back on Earth? Don’t you still need + 1TW of terrestrial power generation? If SpaceXai launches “a few 100GW of AI per year” to space, what is it controlling? Is space AI just for doing knowledge work? Doesn’t 1TW of AI inference in space just create an intelligence saturated economy… crash the value of intelligence, and spike the price of commodities? Isn’t it just the asteroid mining problem in reverse? For context there is 25GW of compute on Earth today. Is the biz case theory that everything on Earth is directed from space? How many watts of intelligence will control 1 watt of physical work? Is it going to be 50:1? This feels like there’s going to be diminishing returns on the marginal unit of intelligence. At some point you’re just chasing commodity prices higher, because the economy is commodity limited and not intelligence limited. Can physical work be much more efficient? Yes a bit more, but 5,000% more valuable? Seems like a stretch. Even any scientific breakthroughs that space AI researches will still need to be physically implemented on Earth to be realised. I’m not sure how this strategy escapes power generation on Earth being economically limiting. Is the bet that space intelligence directs compounding power generation on Earth? Earth is where all the mass is. The limiting factor is always going to be on Earth, is the bet that space AI always knows where this limit is, and is solving for it? Don’t we already know where all these limits are? They’re not exactly hidden, they’re just controversial / disallowed. I’m just wondering what the assumptions are? It seems directionally good, but partially complete.

@gpriner @SamaHoole Rabbits and hares do this too.

@SamaHoole So plant🪴 eaters need to eat their own shit 💩 in order to get there nutrition out of it?

If you really want to optimize plant nutrition like our closest primate relatives: Gorillas eat 40kg of leaves daily, ferment them in massive intestines for 30+ hours, then eat their own faeces to extract nutrients on the second pass through their digestive system. So when your naturopath says "eat like a gorilla," they're technically correct. You'll need the 30-foot intestines, the bacterial fermentation chambers, and a commitment to coprophagy. Or you could just eat meat like humans did and skip the entire ordeal. Your call.

@elonmusk Yes

@CultureExploreX How old? The dating methods are a joke. Specious assumptions produce ridiculous results. E.g. living snails (Melanoides tuberculatus) dated 27,000 years old due to old carbon from artesian springs.

Archaeologists just found a 430,000-year-old wooden tool. That alone should stop you. Wood doesn’t survive. Which means this isn’t the first one. It’s just the first we caught. The stick was deliberately chopped and shaped by early humans, likely Neanderthals or Homo heidelbergensis, and preserved only because it sank into wet mud beside elephant bones in southern Greece. Half a million years ago, someone chose a branch, shaped it with intent, and used it for work. That is foresight, planning, and skill. The unsettling part isn’t the tool itself. It’s how much evidence of early human intelligence simply rotted away.

@aakashgupta Made in USA, B4 planned obsolescence and off-shore manufacturing. MAGA!

The signal strength hitting Earth from Voyager 1 is less than one trillionth of a watt. To put that in perspective, your phone’s WiFi signal is roughly 100 billion times stronger, and it drops a connection walking between rooms. NASA picks up Voyager’s whisper using arrays of 70-meter antennas, then reconstructs coherent data from it at 160 bits per second. That’s slower than a 1990s modem. Downloading a single photograph at that rate would take weeks. The spacecraft itself runs on 8.8 kg of decaying plutonium-238 that generated 470 watts at launch in 1977. Today it produces roughly 200 watts, losing about 4 watts per year. NASA has been shutting down instruments one by one since the 1980s to keep the math working. They turned off the cosmic ray sensor just this year. And here’s the part nobody’s talking about: there is exactly one antenna on Earth that can send commands to Voyager. Deep Space Station 43 in Canberra. It went offline for major upgrades from May 2025 through early 2026. During that window, if Voyager had a critical fault, the team would have had to wait months to respond. A 48-year-old spacecraft built on 1970s computing, running on a plutonium battery that’s lost 60% of its output, transmitting at a power level that barely qualifies as existing, from a distance where light itself takes 23 hours to arrive. And a German observatory just casually picked up its carrier signal on a live stream. The engineering margin NASA built into this mission was designed for 4 years to Saturn. Everything after that is borrowed time the engineers keep extending by doing math with 200 watts.

@Ellieinspace Do you know if the Raptor 3's provide dry O2 for autogenous tank pressure? E.g. heat exchanger vs. pre-burner exhaust?

Starship V2 Booster vs V3 Booster The new V3 (right) has: •Raptor 3 engines (more thrust, simpler, lighter) •Slightly taller booster → more propellant •Integrated hot-stage ring (less mass, less complexity) •3 larger grid fins instead of 4 smaller ones •Much higher payload (targeting 100+ tons to LEO)

The problem with anecdotal assertions is you don't know how much better the results would have been if all those babies were breast fed. Maybe a few less health issues, a few higher IQ points, etc., we can't know without doing extensive studies. The point is: formula and cow's milk are not better for babies than mama's breastbooks! Also, I'm sure it's why I'm so attracted to women's boobs!

@argosaki So what does this mean for those of us who grew on cow's milk who did just fine in school and hardly ever were sick? I don't buy it at all.

BREASTMILK She thought she was studying milk. What she uncovered was a conversation. In 2008, evolutionary anthropologist Katie Hinde was working in a primate research lab in California, analyzing breast milk from rhesus macaque mothers. She had hundreds of samples and thousands of data points. Everything looked ordinary—until one pattern refused to go away. Mothers raising sons produced milk richer in fat and protein. Mothers raising daughters produced a larger volume with different nutrient balances. It was consistent. Repeatable. And deeply uncomfortable for the scientific consensus. Colleagues suggested error. Noise. Statistical coincidence. But Katie trusted the data. And the data pointed to a radical idea. Milk is not just nutrition. It is information. For decades, biology treated breast milk as simple fuel. Calories in. Growth out. But if milk were only calories, why would it change depending on the sex of the baby? Katie kept digging. Across more than 250 mothers and over 700 sampling events, the story grew more complex. Younger, first-time mothers produced milk with fewer calories but significantly higher levels of cortisol—the stress hormone. The babies who drank it grew faster. They were also more alert, more cautious, more anxious. Milk wasn’t just building bodies. It was shaping behavior. Then came the discovery that changed everything. When a baby nurses, microscopic amounts of saliva flow back into the breast. That saliva carries biological signals about the infant’s immune system. If the baby is getting sick, the mother’s body detects it. Within hours, the milk changes. White blood cells surge. Macrophages multiply. Targeted antibodies appear. When the baby recovers, the milk returns to baseline. This was not coincidence. It was call and response. A biological dialogue refined over millions of years. Invisible—until someone thought to listen. As Katie reviewed existing research, she noticed something unsettling. There were twice as many scientific studies on erectile dysfunction as on breast milk composition. The first food every human consumes. The substance that shaped our species. Largely ignored. So she did something bold. She launched a blog with a deliberately provocative name: Mammals Suck Milk. It exploded. Over a million readers in its first year. Parents. Doctors. Scientists. People asking questions research had skipped. The discoveries kept coming. Milk changes by time of day. Foremilk differs from hindmilk. Human milk contains over 200 oligosaccharides babies can’t digest—because they exist to feed beneficial gut bacteria. Every mother’s milk is biologically unique. In 2017, Katie brought this work to a TED stage. In 2020, it reached a global audience through Netflix’s Babies. Today, at Arizona State University’s Comparative Lactation Lab, she continues reshaping how medicine understands infant development, neonatal care, formula design, and public health. The implications are staggering. Milk has been evolving for more than 200 million years—longer than dinosaurs walked the Earth. What we once dismissed as simple nourishment is one of the most sophisticated communication systems biology has ever produced. Katie Hinde didn’t just study milk. She revealed that nourishment is intelligence. A living, responsive system shaping who we become before we ever speak. All because one scientist refused to accept that half the story was “measurement error.” Sometimes the biggest revolutions begin by listening to what everyone else ignores.

@Huba2222 @Bitcoin_Teddy Revolt: $45 car battery ://www.revoltbatteryokc.com

@Bitcoin_Teddy Still a pricey battery. Shop around.

My car battery died yesterday. The dealership wanted $250 for a new battery + replacement. AutoZone wanted $300 for a new battery + replacement. Instead of paying them — I watched a YouTube video and learned how to replace the battery myself. I went to the dealership and bought the battery for $180, went home and changed it. I saved $70 plus learned something new 😎

@NiohBerg Yes!

🔴 I want to clarify something about my coverage, as well as an assessment of how I see the situation right now. World leaders, politicians, media people, and everyone else also, please read on. First of all, yes I have seen the awful videos coming out of Iran, and no, I will not spread them. This is why: They are fighting for their lives right now. It's a war. There are MANY casualties on both the good and evil sides, but Iranians are experiencing great achievements and are inflicting massive damage on the regime for the first time. The regime is panicking and cutting off all communication because unlike ever before, the killings are not one sided. Iranians were even able to find regime figures' home addresses and take them out there. That's why even landlines and electricity are cut off. They are so outnumbered that they imported Arabs and Afghans to kill people. These are trained terrorists, yet people are fighting them with shovels and slingshots - and having victories. Iran is a battlefield, a warzone in the total darkness. I receive many Starlink messages of insane acts of bravery and regime defeat. Yes, our casualties are high, but like I said, Iran is a warzone now. And the people there understand this. There is no going back, they understand the stakes. People inside Iran are tired and unarmed, yes, but they are also HOPEFUL and OPTIMISTIC. I worry that when they regain internet connectivity and see nothing but a visual slaughterhouse of their countrymen, they might go home and become demoralised. I refuse to be someone who scaremongers towards my own people at a time when the battles are still going on. The time for me to share this footage is after we win or after we lose - not while they're risking their lives fighting. Again, reporting on casualties and atrocities is completely fine. Everyone is welcome to cover this uprising as they wish and I won't judge you for it, but this is my own mindset. Iran is in a very critical and sensitive time. It's crucial for everyone to push for the final battle to be won, and my role is to encourage and bring up our fighting spirit. I will not manifest another November 2019. However, the people inside Iran still need outside intervention for the final push to liberate the country, and to this end, I will do my best to make sure world leaders listen and act as they promised - especially Trump.

@RajputRanjanaa @NiohBerg !!

@NiohBerg Share their truth🦁💚 🤍❤️✌🏼

One very underreported reason the regime cut off internet access as well as phone lines is because many regime figures were doxxed, hunted down and killed. Regime media is underreporting just how many casualties they took this way. Pictured: IRGC terrorist who was taken out after people found his home address.

@Honesttruthman @RepNancyMace MARANATHA!!!

@RepNancyMace It’s time to invoke the Resurrection ACT

Tim Walz is preparing to deploy the Minnesota National Guard against federal agents. Someone remind him: Donald Trump is Commander in Chief. And federal authority supersedes state authority. That's not opinion, that's the Constitution. What Walz is threatening has a name: insurrection. Mr. President, the law is on your side. Use it.
