Deeper IR, microwave and radio. Within a galaxy, redshift can be ignored. In another galaxy, the issue is moot, you don't need to worry about them and they don't need to worry about you.

Our current scopes can pick up brown dwarfs with a surface temperature below freezing. An object the diameter of a planetary orbit, with the gravitational effect of a main sequence star and giving off just black body radiation is gonna stick out like a neon "Interesting stuff here!" sign the moment someone does a long wavelength survey of your general region.

Even if you build a swarm instead of a solid shell, you're still going to shift the star's apparent spectrum towards IR, from the swarm radiating waste heat. A star whose mass, diameter and emission spectrum don't match up with the math is inviting investigation, regardless of how you try to mask what you've been doing.

I would think it'd make it more likely that you're discovered when you turn your star into a black ball with a gigantic IR signature where a star should be. Any civilization with a cursory understanding of gravity and stellar spectra would turn every telescope they have on you.

It's hard to tell, but I don't think it's from IFT-6. The banana cam gave us a view inside the payload bay and the reinforcing structures look a little different.

I believe the truss that the banana is strapped to is the same as the one running along the lower edge of the OP image. But if you look at the reinforcements noseward, the OP shows a closer arrangement of three ribs with cross-braces in-between, whereas the IFT-6 image shows more regularly spaced ribs with no extra bracing. The ribs themselves look different, with a uniform line along the entire inner side in the OP, and a shallower middle segment on OFT-6. The OP's low resolution makes it difficult to tell, but I think it's also missing a lot of the lengthwise stringers that SpaceX added on the later ships.

EDIT: I may be talking out of my ass. Had a look at IFT-3 and the view towards the payload door shows the same reinforcing structures as IFT-6. So it's possible that the OP image is from farther up the payload bay, the ribs we're seeing are reinforcing the flap hinges, an area that's not visible in the banana cam. We didn't get a payload bay view for flights 4 and 5, so can't compare those.

EDIT 2: The OP image is definitely farther up the payload bay, looking at the hinge area that we didn't see in other bay views. There's no telling whether or not it's from the 6th flight, based on the publicly available images.

Because if you launch something from Earth, you inherit the Earth's orbital speed around the Sun. At that point, whatever you launched will just continue to orbit the Sun. It takes less energy to accelerate to a solar system exit trajectory than it does to scrub off all of the excess velocity and end up on a trajectory that intersects the Sun.

Even the Stream version doesn't require Steam. You can just run the executable. A few folks over on Reddit claim they've given the game to their friends just by copying the files from an external drive.

Most of the Falcon 9 launches are for Starlink and are paid for by SpaceX themselves. How is that "the government subsidizing them"? If you want to argue that they're using money they got from NASA to fund those launches, is your plumber feeding their family from you subsidizing their life?

There's two main benefits: faster reuse and more payload to orbit.

A Falcon 9 landing on a drone ship needs to be transported back to shore. That's multiple days before the engineers even get their hands on it to prepare for the next flight. The design goal of Starship is to launch a Ship into orbit, return to the tower, be restacked, refuelled and launched again in the same day. Will they actually get it to the point where that's possible? Remains to be seen. Until now, they had no way to see what real stresses a Starship booster goes through in a flight. They're gonna rip this one apart down to the spacers in its bolts to examine it. With the flight and physical inspection data, they'll make what improvements they can to the already built boosters and design future boosters to be more resilient. SpaceX has, by now, a well proven track record of doing what others think is insane to even attempt. If anyone can launch the same rocket twice in a day, there's no one better to give it a try.

The increased payload comes from not having the mass of the landing legs. The Falcon's landing legs weigh several tons. Starship, being 3x the diameter and 10x the mass, would need titanic landing legs. That's a lot of tonnage you won't be taking to orbit. Catching on the tower means that all but a fraction of the landing hardware's mass isn't on the rocket itself. As an additional benefit, the landing hardware needs to be built only once. Every Falcon has its own landing legs, but every Starship they ever build could land on the one tower they have now. That won't be the case, they're planning to build multiple towers, but the sentiment remains the same.

NASA has the measurements of all their astronauts and Dragon flight suits for Butch and Suni are already made.

It's stronger than aluminium, as well as easier to manufacture and work in less-than-ideal conditions than carbon fiber. Useful traits when your end goal is to build a whole fuckton of the biggest, most capable, fully reusable rockets in history.

Because now it's practically a necessity. Before that, you could easily not put a case on your phone, exercise some basic care with it and you would've been fine. None of my previous phones had a case on them. Not a one. Because I don't drop them, I don't throw them and I don't use them for hammering in bolts or whatever. But the camera bump finally got me to put a case on my phone, because the damn thing not sitting flat on a flat surface annoyed me too much.

The show made a fair few changes from the books, mostly for the better. Off the top of my head, Avasarala and Draper are introduced earlier in the show, Drummer got the consolidated stories of several other side characters and Elvi Okoye's and Ashford's personalities were significantly changed. IMO, Show Ashford is a much more interesting character than Book Ashford. In addition, the season 6 side plot with the kids is told much later in the books.

Thunderfoot's psychotic obsession with Musk and the complete denial of reality happening before his eyes it necessitates has destroyed any credibility as a scientist he ever had. The authority of a food chemist on matters of rocket science is questionable in the first place. Your blind, unquestioning acceptance of whatever drivel escapes his frothing mouth is no less pathetic.

And with that, I'm going to toast to the memory of the brain cells I've lost over the course of this "conversation". Hoping for anything even resembling a reasoned argument from you is clearly a fool's errand.

Yeah, you got nothing.

Fucking lol.

EDIT: Hoo boy, you didn't even look at what you linked, did you? My point was that SpaceX has completed 8 crewed missions. The video is just half an hour of Thunderfoot's inane rambling about launch costs. Not a single word about whether or not SpaceX has completed any crewed missions, ISS or otherwise. That's the point I'm challenging you to disprove here. Go ahead. Show your work. I'm looking forward to it.

They have 8 incident-free crew missions under their belt. Sit your ass down, the adults are talking.

What's your reasoning behind the claim that a company that's been transporting crew to and from the ISS for 4 years, and currently has a vehicle docked to the station, is incapable of launching a tenth mission? Mind that said mission was supposed to launch next week, but Starliner is being a pad princess in orbit and won't get off the required docking port.

I suppose I'm somewhat fortunate to have been a poor bastard for most of my life. 25fps with moldy potato settings was just fine, as long as the game didn't crash or deep fry the CPU, so I'm not as sensitive to the occasional drop below 60fps and don't feel slighted when I have to turn some settings down. Though I can understand being incensed when you've poured thousands into a bleeding-edge gaming rig that's supposed to handle anything at 4k, maxed out and a stable 120fps and it's the game itself dragging your experience down.

But the stutters weren't the only problem people reported early on. There were cries of the game being unplayable, on account of endless bugs, visual glitches and repeated hard crashes. Worst I got was the normal mapping on Cal's face getting real weird in certain lighting conditions. That's hardly game-breaking.

I mean if you want to invalidate my lived experience, sure. Played on release on a 5600X, RTX3070 and 32GB of RAM, 1080p, almost everything maxed out. Open areas on Koboh saw a drop to mid-40 fps, but other than that, I had one hard crash and no bugs I noticed.

Gamers when the game has bugs: >:(

Gamers when the devs delay a patch because they discovered it breaks a core system: >:(

They're trying to fix bugs, not make existing ones worse. Deal with it, princess.
