  1. That is what causes the straight walled cone is what I'm thinking, for it to be hyperboloid the pressure would have to be increasing relative to the decrease in pressure that must be happening with distance from nozzle. An acceleration post reaction would have to be occuring. Think of it this way; at what point in the process is each molecule going the fastest? As it exits the chamber or meters behind the bell? Once free of the bell it will not accelerate any faster radially than at that point where it exits the bell. There is no source of additional acceleration and a hyperboloid shape suggests additional acceleration.

  3. I don't understand the hyperboloid either. There is no energy being added so it shouldn't be accelerating radially. A straight walled cone in vacuum makes the most sense to my gut, with some pseudo-hyperboloid when the nozzle is directed at, and near, a surface in vacuum
  4. Some interesting points made here https://spacenews.com/industry-sees-missed-opportunity-in-deorbiting-iss/
  5. Is that a star icon or one of those SOI entry/exit concentric ring things?
  6. Oh look, I found a shuttle craft full of tsar bombs and its guardian mothership is nowhere to be seen. What to do? Hmmm
  7. Well dang. Full disclosure, I don't even run KSP2, but in 1 I've gotten rovers climbing some steep grades with lots of wheels. But I also dink with the traction control and suspension. It really looks like those wheels have a lot less traction than their footprint would indicate. Apologies for getting your hopes up and thanks for testing it out Is there anything you can tweak on the wheels? Especially traction control.
  8. Each wheel has a motor. More wheels, more motors, more torque and horsepower
  9. Moar Wheels. I usually have at least 8, sometimes as many as 16. They need use a lot of juice though
  10. USAF inspired by KSP noodle rockets (not really, but might be true) https://youtu.be/V3aLdAB5jh4
  11. Hopefully the multiple scrolling HUD messages can't trigger a seizure. It can only get better, it can only get better, ..
  12. I would have bet $1M that this was so without this proof. And I don't mean that lightly as I would have had to borrow a lot of money to cover that bet. Next up: proof that Mercury is hot. Article is good read, thanks for posting
  13. I'm guessing that plastics will be broken down by bacteria long before geology gets a chance to work on it much. A styrofoam eating bacteria has already emerged in the wild. Evolution is amazingly fast at that scale
  14. I would imagine a significant factor was that crossbows were likely seen as too complex for the heat of battle with associated maintenance demands and ran somewhat contrary to the warrior code in many cultures which emphasized skill over what may have been perceived as mere gadgetry. Similar currents run today with front line fighters rejecting what the whiz kids behind the lines are certain are wonderful ideas Strangely, many warfighters find waiting for their smart rifle to reboot in the middle of a firefight a deal killer
