Yeah, that showed. I changed nothing. Seems like it could not have been an X glitch, since it worked from phone, but not desktop.
I’ve found that to make it work, you have to copy the link from the little “copy link” icon, then paste it into a browser tab, then copy that link from the status bar and paste it here. You have to wait for it to pop up in the forum window before hitting “submit” too.

Are they perhaps vertically challenged and six in number with oddly descriptive names?

Today I graduated with a bachelor's degree in aerospace engineering! I thought more people would decorate their caps. I'm on mobile so I can't easily post pictures but I'll post when I get home and unpacked.
Shameless plug: I don't suppose anyone here is part of a company looking for a new grad with satellite testing, integration, and programming experience?

This isn't a problem that is best characterised by anecdotes. This is best characterised by statistics and examining the details and intensity of the failures.
Respectfully, you say this, and then anecdotes are exactly what you offered. Here’s a statistic: EV fires are ten, eighty, even a hundred times less likely to occur in the first place. Even if they are more likely to be “catastrophic” (however you’re defining that), that catastrophe is still less likely to occur. By your own statement (brine solution, etc) it’s already a solved problem, it just requires different tactics and equipment. Such is the evolution of fire response from the beginning (fighting a massive fuel spill/fire also requires special tactics and equipment).

In spite of movies, shooting a can of gas will not cause an explosion.
Having a battery-pack land on a sharp rock or bit of metal will likely cause a chemical fire that will destroy the entire battery facility.
Just plugging in a damaged or faulty battery pack could do the same.
Also, Batteries and tires are the two most wear-sensitive parts on a BEV, and who wants to get an 'old' pack with only 2/3 the range of their brand new pack?
Your information here is incredibly out of date. I can’t speak for other mfrs but a Tesla battery can take a significant amount of damage and not catch fire, as each cell is thermally isolated from the others. Here’s a Model 3 battery that went sideways into a tree, did way more damage than “landing on a sharp rock,” and didn’t catch fire.
And speaking of landing on a sharp rock, you hear about the Model Y that was deliberately driven off a cliff, and not only did it not catch fire despite all the sharp rocks, everyone walked away?
Also, the battery of any Tesla made today should last the life of the vehicle, and then some. An “old” pack just isn’t going to see that kind of degradation, any more than a gas engine (which also loses efficiency with age). I can post the graph if you want, I bought my first Model X used with 36k miles, sold it 40k miles later. Over that time my degradation was completely flat, I lost no meaningful amount of range. It used to be that EVs would see a sharp drop of around 10% in the first year, leading to this myth, but degradation then tapers off to little to nothing. Even that no longer seems to be the case with newer vehicles with better battery management.

Will be interesting to see what PLSS they come up with for untethered EVA suits (this mission has an umbilical).

Good article with some equally interesting discussion down in the comments. TL:DR due to potential delays with Starship, Orion’s heat shield, et al, NASA may be considering an Apollo-9-esq mission of putting Orion into LEO to dock with a stripped-down Starship for habitability and other tests.
Or, if you believe the conspiracies, a “camel’s nose under the tent” to obviate SLS entirely…

Given the MSR news... I'm not saying this is a good idea and I'm not saying it will happen, but proposing a manned Starship mission to complete Mars Sample Return is a completely on brand thing for SpaceX to do.
Would be quite the plot twist but the 21st century of space exploration has been filled with so many plot twists already that I doubt anything would surprise me at this point.
Only if they bring back Spirit & Opportunity too.

That would be a very large, and massive pallet. If the sun were directly overhead one could easily get a momentary nice eclipse effect with boat positioned directly underneath it.
For anyone else who’s brain absolutely will NOT let them rest until this useless knowledge is known…
that wood be a pallet approximately 135x82x11ft and weighing 18,750 tons, and is either half the annual production of pennies or all the pennies in circulation as of 2012 depending on which nonsense interwebz source you trust.
so yeah, splash. BIG splash.

Not sure how to get better information than articles actually interviewing Tesla owners…
No, I did not simply read the headline and take it as fact.
It is highly unlikely this was a politicized article. I didn’t clarify in the original post, but the article stated this was happening to ALL electric cars, not just Teslas.
I think the idea of any electric pickup truck- Cybertruck or any future attempts from Ford- are not going to be good ones.
Cybertruck is actually different insofar as it isn’t necessarily billed as a replacement for farm equipment. For urban citizens it should be just fine. It’s only in freak weather it would have issues.
Sadly, nothing related to Tesla is ever unpoliticized for free from bias, either way. Such articles are nearly always missing important context, like the fact that most of the people caught in that mess hadn't bothered to precondition their cars prior to going to charge, which makes a huge difference. Or mention all the people who can't start their gas cars due to... dead batteries. Note you don't hear about issues like this in places like, say, Norway, or even Minnesota, where such subzero (F) weather is fairly normal and people know how to handle it. There's more than that, of course, so if you really want to discuss it I'd suggest taking it over to the relevant Tesla thread.

Now that you've ranted, how about listening?
It's hit over 100 a few times here, but I've never had to get into a burning hot car, because it's always cooled down remotely by the time I get in there.
Also, nudge nudge...

Er... socioeconomic factors and, shall we say, heavy use of alternative pharmaceuticals...

Teslas had a lot of problems in the Great Lakes and Northeast when the winter storms hit in January, IIRC.
On 4/5/2024 at 7:16 PM, AlamoVampire said:@SunlitZelkova the cyber truck has a terrible crash rating and where i am regularly reaches 100+ degrees
I’m just gonna say this: if you truly wish to have an informed opinion about Teslas in X climate, or anything really, listen to people who actually own them, not what some rando on social media or newscaster sensationalizing for ratings/clicks says.

Mars needs steaks.
How many spherical cows can fit in a 13m ShawtyStarShip?
Also keep in mind, they are still planning for ≈18m SS/SH in the long future…
I see it like this: the first Starships to Mars (or a proper lunar colony) will be one-way, with wide, one-use LSS-style legs under heat shields (Martian EDL less demanding?). They’ll carry robots that will build level, solid, Mars-crete landing pads for the next, reusable Starships with stumpy-legs, which will bring the crews to finish assembling the mini-Mars-Mechazillas (MMMs) catch towers, 3D-printed in situ, to start using “standard” Starships.

Wen your job’s not literally a dumpster fire, but close enough.
Sadly the shopping cart, and some dude’s drawers, were a total loss.

Still, consider advances in doppler radar and a steady stream of ground station generated 3D realtime data of wind vectors in the landing path volume being fed into landing AI as the booster descends.
Maybe instead of RTLS on an open pad, land in a large open topped box as tall as the booster that would provide a wind break during the final moments and afterwards. Drone ship landings during hurricanes will likely remain intractable problems however
Or just land it in a massive underground silo like a proper Bond villain.
But speaking of all this, sort of, interesting thread here from a very astute person who IFT-3 Superheavy's return. Counter to Falcon 9 boostbacks, which actually glide a good ways, it basically came straight down. That could certainly explain why it didn't appear to slow down nearly enough, and points to grid fin issues again:

CSS is a discredited hack who hate-mongers for clicks and has been proven wrong pretty much every step of the way. Not really a good “source” to call back.
Oh, and also a media thief.

Apparently the chemical battery was somehow related to PZUs. Complete ignition failure.
Is this one of those one-time-use “missile batteries” that can sit around for ever but once it’s activated, it’s done?

Also, I'm not saying it was this, but neither can this be ruled out at this point either...
