  1. No, it may as well be YYYY/MM/DD, whether it's left-to-right or right-to-left doesn't really matter to me. What really scrambles my neurons, is YYYY/DD/MM, or MM/DD/YYYY
  2. If the timing of the pulses is perfect, and the shock absorbers are adjusted perfectly, it would feel just like 1g. But realistically, it's going to feel quite bumpy, at least like a fast elevator ride.
  3. Manned mission to the outer planets. I'd settle for a submarine on Europa or Enceladus, though.
  4. https://en.wikipedia.org/wiki/Plasma_window You probably want a *very* big capacitor bank, but with a plasma window you can do what you're describing above. Ship/Rover/Dude/Space Monster arrives, plasma window turns on, doors open, Ship/Rover/Dude/Space Monster enters, doors close, plasma window goes off. Or if you have a good enough energy source, you can just keep the plasma window on indefinitely, and only turn it off and close the door properly when you're not expecting any traffic.
  5. You might be able to build such a thing at the Mercury-Sun L1 point, and it could double as magnetic shadow-shield, protecting Mercury from radiation. The station would also need some sort of stationkeeping, it can use the solar wind for that. The same has been proposed by NASA for Mars. You then still have the problem of 1/3 gravity, as with Mars, an atmosphere might not be doable at all, but you can build domes, I suppose. Bring anti-asteroid laser cannons.
  6. The XRS-2200, that is the linear aerospike engine developed for the X-33 and Venture Star. It's not the prettiest, or the most efficient rocket engine ever built, but it strokes my sci-fi obsession in all the right places.
  7. But I did not claim that they are free. I said they are *in orbit* essentially for free. Did anyone pay extra money to get that stage there? No, they did not. It's waste. Scrap. Something that would re-enter the atmosphere in a few years and put on a nice fireworks display in the night sky. With adequate recycling tech, you can grab them, and repurpose them. I didn't even go that far. My claim starts and ends at SECO. The DEXTRE arm extension for example, or a descendent thereof, can refuel satellites that were never built to be refueled. Are you telling me it's physically impossible to cut
  8. And that changes nothing about the fact that the stage is already in orbit. You didn't pay extra to get that stage there, it's basically junk. Someone can now come along, and recycle that stage. Or a new launcher could have a stage already developed with in-orbit reusability in mind. Either way, you ranted about something I didn't even begin to get into.
  9. Now you have a transfer stage, potential fuel depot, or potential habitat in orbit essentially for free.
  10. There were no two "first humans". It's not possible for us to have descended from only two people, the smallest our gene pool has ever been is at least 25000-35000 people. Genetic Adam (the last Man every human is directly descended from), and Genetic Eve (the last Woman every human is directly descended from) lived thousands of years apart from each other.
  11. Well, no. You could make a reasonably radiation-proof suit. But it'd be less of a suit and more of a giant mech
  12. Typically, you don't shield against gamma rays and x-rays. Shielding produces secondary radiation, it's safer to just let it all go through. An interplanetary spaceship might use water, and lots of equipment and cargo stashed in the walls, as radiation shielding, along with a magnetic field against particle radiation.
  13. The X-37B uses Hydrazine as fuel, which is very toxic.
  14. Yeah, I know what you mean. I do play online quite a lot, and come across them quite frequently. Unfortunately, I can't ban someone for being too competitive xD
  15. That's what the "I only play Singleplayer" option is for, having multiple options for the same answer would be redundant.
