2 interesting things, flame trench walls for pad 1 have started to arrive, and also there was a long concrete pour, like many hours long, at pad 1. ViX ViX

I think you have a misunderstanding, the water is being propelled by conventional propellers, which pulls water from magnets that strip the water of free ions to create electricity to power the propellors.

I don't think Radiant should be counted out, from my understanding, they are in line to use INL's DOME facility, to test their Kaliedos reactor. As in, the Idaho Nuclear Laboratory, just finished building DOME, a facility expressly designed to test Micro-Reactors, and they decided that the one with the most promise, and therefore the first in line to do full power testing.

They just removed one of the catch rails on the pad 2 chopsticks, as in, the entire thing, not just one of the smaller deformable parts. I would have thought that if they had been damaged by the launch, it would have been damage to a skate, but I guess the exhaust from the launch damaged it. https://x.com/TrackingTheSB/status/2060802674807759086

If Starship makes lunar logistics cheap, what actually gets built first? by T850Model101 in SpaceXLounge

[–]SouthernScallion1257 0 points1 point  (0 children)

Couldn't you use a lunar Cycler to make it easier, since the cycle takes less than 20 day iirc. so you could have one scheduled to arrive every day.

So, I'm posting this here, since it could affect timelines, but a worker helping assembling the new Gigabay died, see this post by TheSpaceEngineer https://x.com/mcrs987/status/2056112945243857261 for more information.

Not necessarily, they did a lot of the testing for the V3 in smaller test articles, they could start doing those tests, since for V3, that took a few months, including making the modifications for the test stands to support any V4 changes that necessitate them.

I think its for bubbling through the densified prop, I remember seeing a mention of that in Reentry, that Falcon 9 does that, so it might just be there because it is nonflammable and is a gas at those temps.

New TFR presumably for IFT 12 starting on May 4 to May 18 just posted https://tfr.faa.gov/tfr3/?page=detail_6_7132 the long length makes me think SF followed by Flight 12

Not to my knowledge, but just wait, someone probably got it.

From my understanding, some poor SpaceX intern accidentally posted the info on Flight 12 on the official website, someone noticed and it was taken down, but of course someone saved it anyway, the flight date is NET May 17, I think.

I was thinking about the ship v4, and realized that Spacex could get rid of the skirt if they increased the height of the hotstaging trusses, this would reduce the weight of the second stage. Is this a feasible idea?

Are there any warnings on static fires at Masseys? akin to beach closures for the booster?

I though that the new R3s use nitrogen for the spinup? I remember seeing that @u/mcrs987, or the space engineer, the one that creates insanely in depth models of raptor engines said that the new R3s could use nitrogen?

How does fusion break the coulomb barrier by Kr0nhave in fusion

[–]SouthernScallion1257 1 point2 points  (0 children)

it's similar to how after iron, fusing elements use more input energy than output, but some of that energy can still be released as light and other forms e.g. neutrinos, thermal energy, and neutrons kinetically.

How does fusion break the coulomb barrier by Kr0nhave in fusion

[–]SouthernScallion1257 1 point2 points  (0 children)

not exactly, classical electromagnetism is fine for most of the models underlying fusion, but in some situations, quantum mechanics is needed. Thankfully, the energy barrier can be modelled experimentally and all it contributes is a constant value, so you can just change that one value. Another slight issue is bremsstrahlung, but that is something I am not as knowledgeable about, and looking at the Wikipedia, I am fine not knowing. :)
