  1. Of course there are no flat areas near the poles because the projection used on the terrain height map means that it's all sharp peaks and valleys
  2. I've dived the wreck of a late 18th century warship, HMS colossus and the most notable remains other than the canon are the half meter long copper nails for the copper sheeting. They were terrifyingly sharp.
  3. Bone conducting headphones should work in a vacuum. Making sounds to be picked up by a throat mike would be more of a problem. I think without air to vibrate vocal chords, and be shaped in the mouth there isn't going to be any sound to pick up.
  4. Why is whatever the object in the foreground on the left being illuminated orange on the near side, away from the "fireball". Is it perhaps that the photoshopping is a bit amateurish?
  5. I know what they mean, but it just occurred to me that if you were to ask someone in the 60 which would happen first, routine landing of rocket first stages or almost everyone on earth carrying a device that would enable them to video call anyone else on earth they would have thought the rocket thing more likely Weird how perceptions change .
  6. Just to confirm my intuition I just did a test in ksp. I built a simple two stage rocket with about 5000 m/s delta v with fairly low twr. First launch was directly upwards and it arrived at the edge of kerbin's soi with a speed of 856m/s. The second launch did a conventional gravity turn before burning parallel to the surface. That one arrived at the soi with 2000m/s So it seems clear that the gravity losses for burning directly up are pretty substantial.
  7. Not saying it would be easy but antimatter at 4k would be more likely to stay put than plasma at 150,000,000 k. Or at least be a very different problem.
  8. I like this new euphemism for exploded "one engine failed energetically"
  9. Where are upper stages launched into editorial orbits disposed of? The plane change delta v for a launch from kourou for example is going to be too large to allow disposal in the usual south Pacific graveyard. Do the stages aim for the equatorial Pacific and hope not too hit anything?
  10. TIL that the British navy no longer issues a rum reason, but sailors are allowed to purchase up to 1.5 pints of beer a day
  11. I'm seeing an issue where if I use teh x button to remove a maneuvre node alarm from the list it removesa random slection of alarms from the list
  12. I have discovered the acceleration rate the bug occurs at depends on the whether you have Even Better Time Warp enabld. With it enabled it kicks in at 10,000X, without it it kicks in at 100,000x Ok, a proper bug Report Relevant other mods - Even Better Time Warp To reproduce Create a ship consisting of a 3-px gumbal capsule, with two kerbals inside, recycler enabled and set to maximum For power I used the Sm size uranium reactor and I provided additional food Launch Go to just below the critical warp value (1,000x or 10,000 depending on event better time warp). Observe that, as expected, o2 and h20 do not drop. Increase warp 1 notch - o2 and h20 start dropping rapidly
  13. Great to see sophisticated mods starting to appear. Is it a know issue that above 1000X timewarp the receycler matchs starts failing an dresoureces that should be infinite start dropping?
  14. To be fair the natural intelligence does require a support system that requires more than just the 20 watts. For the average USAian it comes to just less than 10kW.
  15. A paywalled article on Bloomberg suggests that spacex employees are going to be offered a deal to sell their shares at a total company valuation of 175 billion, so going bankrupt imminently seems unlikely.
