What have you been playing recently? (Other than KSP)

Still breaking ships... That panic when you accidentally trigger the reactor meltdown sequence as your O2 is running low, and you have to go refill your O2 before cutting the reactor loose and sending it to the barge - or hoping you can cut it loose and get it on the barge and still have time to get more O2... -

I know it's in super slo-mo, and IIRC it's a small engine, but that start looked a tad rough. But what do I know, I'm just armchair rocket scientist. -

Go to get the RV ready for the road, only to find that (I think it's) the hot water tank sprung a leak, lots of water underneath it. E: Yup, it's the tank. Apparently I managed to not drain the hot water tank when I winterized. Maybe I opened the drains after isolating the tank? The trials of a rookie RV owner. First time winterizing a travel trailer FAIL! On the bright side, it's 15 years old, when they usually only last ten, so I guess it was about that time...

totm nov 2023 SpaceX Discussion Thread
StrandedonEarth replied to Skylon's topic in Science & Spaceflight
Depends on the size of the arena. I imagine bouts of any type would need to adapt to zero-gee: A spherical or ovoid arena, consisting of pushing off the walls and striking/defending on the fly, before reaching another wall and pushing off for another pass. It would be more like jousting than anything else. Reentry should normalize everything, if the steel gets hot enough. And that's the point, that the steel can take the heat, so... I should clarify that the discussion is whether a magnet will stick to the steel, not if the steel will become a magnet. There may be some weird effects resulting in the hull becoming a magnet if reentry is near the poles, but that's pure conjecture based on the magnetic flux and charged particles found there. Pure guesswork, but I don't know enough physics to figure out if that's even a real possibility. -

I just did a bit of testing on my stamped stainless steel sink. While the least-worked flat parts seem to be very weakly magnetic, the corners (with the most deformation, obviously) attract the magnet much more strongly. So I would expect the domes and especially the thrust structure to be at least somewhat magnetic, but the main rings probably will only be very weakly magnetic, if at all. Any holes that are cold-cut (not torch-cut) will probably be more magnetic around the edges. But I am also not a metalworker, although long ago I had the start of an engineering education which included some metallurgy. But I probably learned more today from Google than I knew before. E: Weld zones will probably not be magnetic at all, as the metal has (probably) normalized, depending how quickly it cooled. -

Since 3xx series stainless steels are (usually, there may be exceptions) austenitic, magnets will not stick to them. Magnets will stick to ferritic or martensitic stainless steels, such as some 400-series stainless steels. Source E: Correction @kerbiloid: Not sure how much cold-working goes into Starship. It is cold-rolled stock they use, so it just may be. Also: But yet my stainless-steel sink is not... -

Starstream. I suppose Starship scrap would be make it far too heavy. But who cares when it's being towed by a Cybertruck? -

Sure looks that way. Do I assume that's a little worker camp? I wonder if they got a bulk deal on Airstreams? I wonder how many Airstreams they could build with all the steel they've scrapped? I know, they're made of aluminum, but.... SpaceX edition Airstreams? -
And that's why I bought (er, requested and received for Christmas) a dashcam. Not that I've been hit, but with one young adult driver in the house and another soon to get a learner's permit, I figured it was a good idea. That and the 100km/day I clock on the highway. I haven't caught anything worth posting on it, but there were some clips worth keeping. Like the dude who started to stop for a changing light, then blew through it as I was trying to turn left across his path. Close call there. In hindsight, it would have been nice to get my own dashcam, as I probably would have gotten a better one. That's what happens when my wife buys me tech.
