  1. Well, another successful flight! It seems like they hold a lot on these launches, I think they should be trying to minimize that for flights with ordinary people on them.
  2. Nobody should feel bad for Pluto, nor any other dwarf planet. We're not declassifying a person or a dog here. Creating a new classification to better describe new discoveries is perfectly scientific. The difference between a dwarf planet and a planet is arbitrary, but it doesn't make Pluto, Eris, Sedna, Makemake, Haumea, Orcus, or Arrokoth any less of a world. Pluto has not been made less interesting. The beautiful water mountains and nitrogen plains have not been changed by a council on the distant Earth. Pluto is a world. Planet is fine, dwarf planet is fine, they are synonyms of 'world' to an extent. This is not a problem.
  3. They will have to worry about keeping the nose tank cool while it's entering an atmosphere, won't they? That'll be a little harder than having them inside the main tanks like before.
  4. I already build stuff, at least when learning a skill is more valuable than the final product, or when the thing I want doesn't exist. I buy a lot of the things I need, but I also spend time inventing new things.
  5. Thermal regulation requires an element which can dissipate heat away from the human, or whatever you're protecting on the surface. This is an issue because the ambience is 400 degrees C, and that part needs to get hotter than that to wick heat away from anything, and then it needs to wick over 350 degrees out of a fairly large volume. That's a far greater temperature difference than cooling something from Earth ambient to absolute zero...
  6. KSP is nice for learning the basics and playing around, but it's far from a real engineering simulation tool. If you're looking to actually build something, I'd look into getting your hands on an educational license on Matlab and something like ANSYS. These are tools that engineers use to make rockets. They can be expensive, but if you're a student you can usually wrangle a free copy.
  7. Crew-1's Dragon will be called 'Resilience'. Also, the Americans will vote from space.
  8. Eh, boosting has been done from forward and nadir positions before. Does this new cargo version use the IDA or the square hatch? Because certain large items don't fit through the round hatches...
  9. Teletubbies is a post-apocalyptic dystopia.
  10. I think that if the planet were covered in an appreciable amount of city lights which made the night side less dark, in a solar transit we would simply undershoot the radius of the planet, thinking it had less area to block the normal solar light. If it was one of the few planets we're capable of directly imaging, we'd probably overshoot the size of the planet or associate that tiny extra brightness with microscopically brighter rocks or clouds. I don't think city lights in other star systems can be detected reliably.
  11. My guess is that there were pools of water with enough chemistry shenanigans going on inside, catalyzed by volcanic heat and solar energy and lightning, that the whole puddle acted sort of like a cell, strung up some RNA, and eventually mutated into something with membranes organizing things. It's reasonable to assume this happened on Earth, but as long as Venus or Mars had similar environments at the time I don't see why life shouldn't have sprung up on all three.
  12. They should release some full duration ultra-high quality rocket firing audio...
  13. Probably both? -Structural failure and/or rapid disassembly -Great data, as aerospace engineers are always collecting data during tests But "Tipping Point" does not refer to the typical Kerbal landing in this case...
  14. Newtons are a unit of force, and thus weight. The kilogram is a gravity-independent unit of mass.
