Prehistoric gif coming in!
It’d need to be 13 to 80 times more massive to be a brown dwarf.

If it gained mass rapidly, most all the moons would likely destabilize since they’d have way too little velocity for the orbit they’d now be in. But if they sped up to accommodate, it’d depend on the density change of Jupiter. The fusion would push out material a bit, but the density would probably just increase because of the increased mass.
But if the density stayed the same, the radius would be 2.4 to 4.3 times larger than currently. With Jupiter having a radius of 70,000 km, that’d put it at 170,000 to 300,000 km radius. That’d put Metis and Adrastea inside 170, and Amalthea and Thebe inside 300. They’d already be heavily inside the jovian atmosphere, so they’d be toast. Io, Europa, and maybe others might also fall due to higher atmospheric drag at those levels.

I think the rest of the moons would be planets then, and the solar system would be a binary system.
My friends with a lot of kids got a used airport limousine. I guess it was cheaper than an express van at the time. That was pretty cool and unique.
4.8kg per day gives 1.75 tons per year, giving an 800% increase. That’s still really big, thanks for tracking down the numbers.
48 tons per day, so it’d need to be less than 0.08% aluminum to double it.
Yeah you’d need to put up fewer sats per launch. But they might still have enough lift capacity on starship to do that.
Wood is interesting, but the article doesn’t address off gassing at all, which is a huge problem for communication satellites. Is there a way to keep the wood from off gassing? For 3d prints in vacuum, they metal coat them to keep the gas inside. Or maybe you could resin soak them? With hopefully an extremely UV stable resin. But I didn’t know what the weight trade looks like then, resin is heavy.
But if you’re looking composites anyway, carbon fiber would be another great option. Lightweight but with a few manufacturing constraints. But should burn up to carbon dioxide on reentry.

About 48 tons of meteorites enter the atmosphere every day. I couldn’t find the elemental distribution, but I’d guess there is some aluminum in there. How much of an increase is 14 tons aluminum per year over the many tons of aluminum entering the atmosphere already? That might be good to get a rough estimate of how impactful this is.
SpaceX has been receptive to design changes to starlink in the past to minimize impact, like decreasing reflectivity and reflection angles for astronomers. They might be receptive to moving to different alloy for the body construction.
Magnesium comes to mind that would be light but expensive. Steel alloys might be cheap and heavy options for later when starship is operational. Would those have similar effects on ozone, or is it only the aluminum oxides?
Lol, Microsoft will focus on profits and shareholders, and shareholders want AI cramed into everything.
But I can’t remotely set their allowable usage time and access list. Maybe dual booting would work though.
My issue is family control. I haven’t found a way to get Microsoft family type control yet on Linux, since my sibling uses my computer. The syncing time allowed across devices is the hard part.
I always said hypersonics are better at taking down carriers from my first comment here. But China didn’t have effective carriers. Hence why the US didn’t need them.
I said the US ones were extremely expensive, and you agreed. And that cost is the one that matters for the US.
Nuclear weapons aren’t useful in a conventional conflict by definition. So what is Zircon for if it’s not for MAD nuclear warfare and not for conventional warfare?
Just over 1 min to close 100mi. That’s actually much longer than I was thinking.
Did I ever say hypersonics were ineffective? I said they were expensive. And that stealth bombers are also effective at the ground attack role. Nothing you’ve sourced has contradicted that.
Aside from that, ballistic missiles can also get though most air defenses. MAD still works because you can’t be sure about reliability shooting down the missiles. Having even better more expensive ones doesn’t really change the math, which is why Zircon is so stupid.
Since China is now getting carriers, the US is testing hypersonics.
I’ve usually seen just one smaller bird pestering the larger one.
What system are you thinking? I’m sure the US can emulate it. Obviously systems can detect stealth aircraft if they’re right on top of them, it just makes the targeting effective radius small enough to be nearly useless. Detecting doesn’t mean much if it’s just a notification that there’s a stealth aircraft somewhere within 100mi.
The sources you gave earlier about detecting stealth are low frequency radars. And they said they’re good for detecting stealth fighters. Stealth bombers are more tuned for low frequency. (hence their goofy shape) Plus low frequency is very very difficult to get a direction to the target because of it’s scattering, it moreso just tells you there’s something there.
Kinzhal (the missile the articles are talking about) is the ballistic missile I was taking about, it’s not a hypersonic maneuvering missile.
There are 16 thrusters on the service module and they only need like 4. One is malfunctioning. They’re trying to diagnose the problem to fix it for next time since the service module burns up on reentry.
