Falcon Heavy launches exploration misison
Falcon Heavy sent Psyche toward a metal-rich asteroid, Europa Clipper to Jupiter’s Moon, and GOES-U into transfer orbit to improve NOAA’s weather forecasting. Falcon 9 launched NASA’s PACE mission to study Earth’s ocean and atmosphere and SPHEREx to map the history of the universe. The Falcon family has enabled NASA to reach farther and explore more of the universe, and missions like Roman continue that work

Jensen Huang says the first AI supercomputer he ever built had exactly one customer on earth: Elon Musk. Back in 2016, he had just created a machine called the DGX1. It cost $300,000 dollars. He announced it on stage, and the room went completely silent since nobody understood it, so nobody wanted to buy it. Since Elon knew him because Nvidia had built the first self-driving computer for the Tesla Model S, Elon bought & tried it. Elon said he had a small company that could use it. Jensen boxed one up himself and drove it to San Francisco. He carried it up to a room full of researchers. That tiny company turned out to be OpenAI. The machine nobody wanted went on to launch the AI revolution. — Jensen Huang (.@JensenHuang)
Elon Musk says the AI boom hits a WALL this year when we run out of power to run the chips. He says the whole industry is about to learn a hard lesson in hardware. Chip output is exploding, but electricity is nearly flat everywhere outside China. So the two lines cross this year. He says by the end of the year, we will be making more AI chips than we can actually turn on. Millions of them pile up with nowhere to plug in. In his words, the bottleneck for the next year is not chips, it is raw power. Whoever can turn on the most chips fastest wins the race. In the end, the AI race comes down to one thing: Raw electricity. — Elon Musk (.@elonmusk) on Dwarkesh Patel's (.@dwarkesh_sp) podcast

Why Starship The point of Starship is not that it is the biggest rocket. It is that mass to orbit stops being a one-way ticket. @elonmusk “It's the first rocket design that is capable of full and rapid reusability.” Translation: every other orbital rocket is still a disposable truck. Starship is built so the truck comes home and goes again. Refill is the next chapter. Reuse is the breakthrough. 1. Falcon Heavy: ~64 t to LEO (expendable) 2. Starship V3: >100 t to LEO reusable (SpaceX’s stated target) 3. You cannot make enough rockets unless you can refly them 4. Flight 13: Ship came home intact after entry You cannot become multiplanetary on expendable trucks.

Keeping up with the Kardashevs
Elon Musk reveals why, measured against the sun's energy, human civilization barely registers as existing at all: "Right now we're very low on the Kardashev one scale. If you say what proportion of our planet's power are we harnessing, it's a very, very tiny number. And we're harnessing almost nothing of our star's power. The sun is truly an immense thing. It's difficult with words to characterize just how immense the sun is" "The sun is about 99.86% of all mass in the solar system. Most of the remaining 0.14% is Jupiter. The entire mass of Earth is in the tiny miscellaneous category. Earth is a tiny dust mote compared to the sun" "We currently use much less than a trillionth of the power output of the sun, and a trillion is a million times a million. So basically we're practically nowhere on the Kardashev two scale. On the Kardashev scale, we're still non-existent. We're not registering"

Grok @Bot buys a Tesla!
Grok Bot can literally buy things for you on the internet now. Here’s a wild example: @Baconbrix asked Grok Bot to buy him a Tesla, and it actually placed the order for a Model Y. Grok Bot is getting insanely powerful. 🚀

I made a video about what happens when you execute `c = a @ b` in PyTorch, from the code to silicon. Hopefully it will help you appreciate that simple line of code more. Made by Grok @bot. Enjoy!
It's beneficial for a software engineer to learn chip design so they understand how numerics flow through circuitry each cycle.

True
Reusable rockets broke the cost curve, and when the price of orbit collapses, we're going to open an entire economy above your head. Welcome to [soon] to space.

This is the way. The Left will attack people for thinking like this because it would mean putting an end to their racist Affirmative Action and DEI programs.

Starship is designed to completely change the economics of space It is unlike anything humanity has ever built before The amount of engineering SpaceX has packed into this machine is insane... constantly pushing closer to the limits of what physics allows Everything around Starship is built for insane scale: payload, reusability, launch cadence, propellant, orbital infrastructure, the Moon, and Mars Anything humanity wants to build at serious scale in space eventually comes back to one machine that makes it possible: Starship This is the kind of scale humanity used to only imagine Everything changes when you realize Starship is no longer just a “rocket” It starts to look like a transportation system built for an entire civilization

Consensus estimate is that ~15GW of AI compute produced in 2027 cannot be turned on in 2027. This is harder than just finding power, as you also need to build out all the transformers, wiring, liquid-cooling, (massive) chillers & complex networking. grok.com/share/bGVnYWN5_4f06…

Wow
Met a German founder this week and asked him if all the stories one reads about the challenges of startups in Germany are exaggerated. "No, they're understated." Proceeded to describe spending a full day having a 90-page investment contract read to him (mandatory under German law; § 13 BeurkG) by a notary that then charged €30,000. That was for his first company. His second company, needless to say, was not incorporated in Germany.

Replying to @TeslaBoomerMama
SpaceX and Tesla are each building 100GW/year of solar production capacity as fast as possible, but natural gas will still be needed to supplement and bootstrap solar for several years. The limiting factor for nat gas turbine production is casting the blades & vanes. By doing in-house casting at SpaceX, we can accelerate nat gas turbines coming online by up to 18 months, which is a profound game-changer.
