  1. Yowza! Johnny better watch out, he's no longer the best that's ever been.... Not sure why this got stuck in my head today. Probably because the randomizer in my phone seems to like it lately.:
  2. Yeah, there’s no accounting for “Bad Taste” (yeah, it’s a movie, so bad it’s funny. I think it even got a plug on “The X Files”)
  3. Kitty really likes pulling all the Kleenex out of the box. I think she uses it to clog up and stall the roomba
  4. It’s been awhile since I played Combat Flight Simulator 3, but in it there was a German plane with an anti-ship cannon. I forget what caliber….
  5. A common improvised explosive device in the Star Wars Expanded Universe is gimmicked blaster power packs, or other power source
  6. Yeah, but, there are plans and counterplans https://www.forbes.com/sites/jamesconca/2020/03/09/mining-the-ocean-bottom--is-this-a-bad-idea/?sh=752a07697f46
  7. The concept was proven aboard ISS. This is more advancing the concept than commercial production, but this isn't your garden-variety bulk fiber either. This is high performance stuff, worth a premium price. Oh, and that bulk fiber data is for install ready jacketed fiber. What percentage of mass is the sheathing? They'll only be making pure fiber up there, sheathing will be added on the ground (if needed, depending on application, I suppose). At least that would be the logical assumption. I can't seem to Google up the mass/meter of just the fiber, but I'm guessing much less than a tenth of the mass of a cable, never mind the mass of the much-larger commercial spool. That changes your numbers considerably.
  8. It seems that zero-gee manufacturing is closer than we think.... https://www.nasaspaceflight.com/2021/09/varda-space-manufacturing/. The plan is to use ISS-proven modules supported by a RocketLab Photon bus. While the specific product for the mission is not confirmed, the ISS has tested optical fiber production with twenty times the performance of groundside-produced fibers. While finding and reviewing this thread, I noticed this: 3D "Printing" is a modern thing, yes. Additive manufacturing, however, is not new. Just look at these beautiful built-up welds on these Saturn V gimbal mounts, done by hand. Same process of adding layer upon layer of material...
  9. One would think so, but may as well check it all at once in case adding one thing perturbs another just a bit
  10. To the tune of "Soft Kitty" "Playful kitty, painful kitty, Little ball of claws. Scratchy kitty, bitey kitty Ow, ow, ow!"
  11. The biggest issue with horizontal takeoff for atmospheric flight to space is getting that huge mass of fuel/propellants up to speed, never mind stopping it if the takeoff is aborted. It would require massive landing gear or a ground-based takeoff carriage.
  12. I wonder what temperature would be needed to completely vaporize/plasmafy regolith so it can be run through a distillation column (or zero-gee multi-level centrifuges) so the various elements could be separated that way. Actually, once plasmafied, magnetic fields could be used to separate the elements by mass, similar or identical to a mass spectrometer
  13. Careful what you wish for…. ”Have a nice TRIP, see you next FALL!” as the old schoolyard prank goes… E: Maybe “autumn “ would be a better choice of words when imps are around…
  14. Fun fact: when developing the A4 (which became the V2), rather than develop a new, larger injector for the larger engine, von Braun and crew used eighteen proven injectors. How many injectors can one use on a single chamber before it gets sillly? So yeah, scaling that up would not work
  15. Explore with Perseveance! https://mars.nasa.gov/mars2020/surface-experience/?drive=0&site=7
  16. Oh c’mon, you may as well complain about Star TrekWars
  17. And Psyche would be “Tin Roof Sundae” flavoured
  18. The Moon could be cheesecake? Er, cheesecake chunk?
