  1. 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
  2. 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.
  3. 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.
  4. I should clarify - do submarines have lifeboats they can launch when under? A large spaceship could conceivable carry some small emergency landing pods, but these would not be suitable for extended deep space/interplanetary use.
  5. It’s the difference between balancing a broom on its handle and balancing a hockey stick. Because the center of mass is slightly offet, the starship Will land at a slight angle and impact the feet on one side first. for all we know the legs are designed to crush on impact...
  6. well if it lands hard at an angle some of the suspension could crush.
  7. Assuming this rod doesn’t collapse in on itself due to its own gravity. Applying a force at one end of a solid object would compress the object like a spring, causing it to shorten slightly over its length. If it has a decent modulus of elasticity, it will then rebound to its original size. This strain will travel through the material at some speed consistent with its material properties, but much slower than the speed of light.
  8. But most of that industry also relies on the high quality gravity freely available on the surface of a planet...
  9. That would be perfect, you could redesign it every two weeks along with SpaceX!
  10. it worked that last I tried it for 1.8.
  11. What’s up with all the loose rocks piled around? Did they break loose?
  12. What’s 18 tons and needs to be in a polar orbit?
  13. It’s all been downhill since Kubrick overruled Clarke and kept radiators off the Discovery.
  14. Nah, Apollo 13 was unrealistically short. The film should have been 6 days long.
  15. Its surprising they haven't had any major leaks given the buzz about their projects. It does seem like they have decided to take the more traditional approach of lobbying hard for big projects and then sitting on them as long as possible.
