"Hahaha, he clicked the Big Picture Mode button again instead of minimising Steam! We got him again!"

I’m assuming @ZacksJerryRig is rage baiting at this point so no engagement for him. My response was to the initial claim that GPUs simply produced too much heat to cool, which is nonsense. Jerry tries to salvage some dignity by moving the goalposts… and makes another blunder.

I've seen a lot of people saying that AI datacentres in space will not work due to the thermal energy from the GPUs. So, I went and actually did some calculations to see how easy it would be to cool down these satellites. (Spoiler: these satellites will work) CALCULATIONS: So, starting with the Stefan-Boltzmann law: Q = ε×σ×A×(Tₛ⁴×Tₑ⁴) A in this equation is the area required to radiate all the thermal energy. Rearranged to solve for area including extra energy radiated from the Sun and Earth: A = Q×Qₑ/ε×σ(Tₛ⁴×Tₑ⁴) Q = watts of thermal energy. SpaceX is aiming for 150KW of power from the solar panels which I have assumed will be entirely converted into thermal energy. Qₑ = watts of thermal energy from radiation from the Sun and Earth. I guessed a value of around 25KW of extra thermal energy incident on the satellite's body, which is probably a MASSIVE over estimate since the satellite is flat and facing 90 degrees relative to the sun. The solar panels wouldn't transfer much heat either through the tiny metal parts which they are attached to. ε = Emissivity of the surface. Apparently the radiators on the ISS have an emissivity of 0.92 so, assuming no advancement in the technology in the decades since they were made, I went with that value. σ = Stefan-Boltzmann constant 5.67×10⁻⁸W/m²K⁴ Tₛ = Temperature of the radiators I am assuming a temperature of 25°C (298.15K) for the satellites, which is quite cool considering the GPUs will probably be operating at temperatures at or above 70°C. Tₑ = Temperature of the surrounding environment Space is about 2.7K (-270.45°C) Putting all of these numbers into the equation: Area = (150×10³ 25×10³) / 0.92 * 5.67×10⁻⁸ × (298.15 × 2.7⁴) = 424.55m² Now, 424.55m² sounds like a big radiator but let's find out how big each one will actually have to be. Each radiator is double-sided so we divide the area by two which gets 212.27m². Then, since there are two radiators, divide by two again to get 106.14m². The Starship payload door is about seven meters wide, but let's cut down the width of the radiator panels to 6.5 for a little more margin. 106.14 / 6.5 gets us 16.33 meters long. CONCLUSION: In the renders provided by SpaceX, the radiators seem just a little too small according to my calculations. However, I made sure to chose values according to the worst case scenario in my calculations. Just removing the heat radiated from the Sun and Earth from the equation (which I believe would be negligible due to the position of the satellite) returns a length of 14 meters, which is much closer to my estimated length of 13 meters from SpaceX's renders. Using the actual numbers would probably give a radiator with a size very close to what SpaceX has shown us. So, after actually doing the maths, I believe the designs which SpaceX has shown will work just fine. It turns out the very intelligent people at SpaceX know what they are doing.

Finished Season 1 of Re:Zero. ★★★★★

guy who thinks china has space ambitions for the betterment of all of mankind

We need an HLS update @elonmusk. I am not wanting to wait for an episode to release for us to get one.

SpaceX, imma need y'all to do me a favor and lock the fuck in.

Time to build major base on the Moon!

NASA has designated 3 “Moon Base” missions Moon Base 1 - Blue Moon MkI Moon Base 2 - Astrobotic Griffin Moon Base 3 - Nova-C PRISM These landers will aid in and contribute to the formation of the Lunar base

No burn-throughs. Shield held.

I built a ∆V loss model and aerodynamics is included. For starship gravity loss is ~ 1600 m/s and the aero loss is just ~ 30 m/s (minimum cross section) I didn't use a gravity turn which is why the cross section stays constant, the aero loss would be higher otherwise (Expand)

Respectfully, I am not sure how it was the “wrong forum.” I was testifying under oath before the United States Congress. I was asked a question about the status of the Gateway hardware, and I gave an honest answer and shared our intent to work with industry and partners to pivot, as appropriate, toward surface applications. It might be worth going back to the tapes if anything was unclear. I do think it is a bit interesting that the goalposts have moved, maybe not necessarily from you, but my initial description of the problem was challenged as 'outright false' or worse, and now it is being acknowledged as factually correct, with the concern shifting to whether I should have referenced a “repair plan,” when I am not sure there is a deterministic approach to repair, nor that one is even warranted at this point. President Trump’s National Space Policy calls for America to return to the Moon and establish an enduring presence on the Moon (not above it), to build a Moon Base! And I have no doubt, based on the expected contributions of our many great international partners, that NASA astronauts and our allies will be standing shoulder to shoulder on the surface of the Moon in the years ahead.

Is this the same tent? Was taken a week ago on the NSF McGregor stream. Seems to be testing inflatables?

🇺🇸🇺🇸 Welcome home! 🇺🇸🇺🇸

And splashdown! America is back in the business of sending astronauts to the Moon and bringing them home safely. Reid, Victor, Christina, and Jeremy did an outstanding job. These talented astronauts inspired the world and represented their space agencies and nations as humanity’s ambassadors to the stars. This was a test mission, the first crewed flight of SLS and Orion, pushing farther into the unforgiving environment of space than ever before, and it carried real risk. They accepted that risk for all we stood to learn and for the exciting missions that follow, as we return to the lunar surface, build a Moon base, and prepare for what comes next. And they were not alone. The entire NASA workforce, our commercial and international partners, and the hopes and dreams of people all over the world were with them. The astronauts know it, and you should too. This mission would not have been possible without you. Congratulations. Artemis II, mission accomplished.

.@POTUS: "What was your feeling when you had no communication?" Victor Glover: "I said a little prayer, but then I had to keep rolling. I was actually recording scientific observations of the far side of the moon... We were busy up here working really hard, and I must say, it was actually quite nice."
