They compare to the thickness of a dime but only show the face! no sorry I misread it - there is a dime edge, I thought that was supposed to be the centaur V tank. Why compare to a dime in the first place? (Although dollars are pretty common internationally, I doubt dimes are.)

On magnetic roller skates? Or do you mean on the inside?

Unless that trash becomes historical -then its "maybe we shouldn't be disturbing this trash heap."

Pounds-mass is only a thing if you know your reference gravity. This is the textbook example of not being able to assume g = 9.81 m/s2 = 32.2 ft/s2 everywhere. Sloppy unit conversions kill space missions just as dead as faulty rockets.

Moon pounds or earth pounds?

I don't really follow auto racing. Are there any top level races that allow electric cars?

So, "it works in KSP" is like TRL :3.5?

Didn't the Air Force give them some dev $? Could they use it for another project?

They don’t need any more crashes!

They were trying to hit F9.

You guys should work for NASA, with this level of effort you could make the SLS make sense!

Nah, I saw Ad Astra, real astronauts are emotionally stunted sociopaths with suppressed daddy issues.

What's the up/down down count on starlinks these days?I can't keep up!

2 sensors I would find very useful to be part of my day-to-day tricorder: - Laser tape measure - infrared thermometer

RIP Toots Hibbert.

Sorry to hear that @Errol. The difficulties of rocketry can be a great metaphor for relationships. To get it right you may have to try many times, and when it goes wrong, you have to look at what happened and try to fix it before the next flight. But metaphors only get you so far. Relationships are their own kind of hard work, both to get started and to maintain. But as someone who has been there, I'd say it was worth the effort to get through it and make it work. Better luck next time, eh?

@tater , has this thing flown over your house yet?

Well they are floating upside down in the superfluid.

ok, which one of you knuckleheads...? https://www.thedrive.com/the-war-zone/36096/airline-pilots-landing-at-lax-report-a-guy-in-jetpack-flying-alongside-them-on

So, space submarines then?

Stuck the landing!

Should UK be on that list still?

But Earthly TBMs tend to have decent support from underneath. This would probably be sufficient for supporting the structures own weight, but remember, the train will be exerting force on the ceiling, so the loading will change direction rapidly.

That would be really interesting to design. Dwarf planets would seem unlikely to have very strong soil or rock, unless the whole thing is a solid chunk of iron. You would need to balance the centripetal force created by the train with the weight of the overburden of the soil, which wouldn't be much.

wow!
