    I noticed that to. Guess early players didn't use displays.
  2. DAL59
    True. And VG has a bad reputation for not delivering. They have literally been saying "6 months away" for 7 years now.

    Orbiter 2010?

    The BFR will certainly put virgin galactic out of business. It could also launch giant probes to the outer solar system. Or giant telescopes.
  5. DAL59
    No...what is it?
  6. DAL59
    Why????? No, space is not for cats True, but it would accomplish nothing(plus we should save the deserts for solar arrays). A mars colony would likely cause scientific innovations, ensure human survival, and just be interesting. As Arthur C. Clarke said, space travel is the "moral equivalent of war".
  7. DAL59
    I agree. I just meant setting up a small base on Mars would be easier than putting a million people in LEO.
  8. DAL59
    Humans always are much, much more capable of science and creativity than robots. Maybe so, but that doesn't mean it isn't going to happen.
  9. DAL59
    However, you could have skylon SSTOs.

    Or just launch a bunch of reusable ships. (BFR) True, but we know humans can survive at least a year of zero gravity, so there can't be a problem with Martian gravity so dire to require immediate evacuation. If humans can't survive Mars gravity for several years, a few months in trnasit back to Earth doesn't make a difference. I agree, but I thought you were talking about an actual orbital colony, with several hundred people. It would be easier to sent a few dozen people to Mars than build an O'neill cylinder. Or you can test lunar gravity with a lunar base. Only three days return time. However, I do not think you could test Martian gravity on a lunar base. Mars is much more suitable for colonization than the moon.

    I know. It is a terrible idea. What's the difference between studying .38 gees on Mars vs in an orbital colony? Why not send some mammals to Mars too?
  12. DAL59
    Why use side boosters instead of dropping from a plane? That exists, and is called stratolaunch.
  13. DAL59
    It automatically quoted you. I was quoting your quote of @GreenWolf An Everest space center would give maybe 1% more payload per rocket for much, much worse logistical and weather difficulties. Not worth it. (Though I wonder if New Shepard could be used to hop tourists to Everest)

    Even with only chemical propulsion, an EOR Saturn V mission would have been possible. If the SLS didn't have to build a DSG, Zubrin calculated it could do a two launch manned Mars mission. I agree that maybe 3/4 of space colonies will be orbital O'neill colonies. (You can't just spin up an asteroid though.(They break apart.)) However, planets are still useful, because you have abundant resources all in one place, plus natural gravity, and no danger of running out of fuel for mobility.
  15. DAL59
    Yes. There were plans to use the Saturn V to sent a manned mission to Mars. It takes equal delta-vee. We already have carbon nanotubes, and synthesizing speeds keep improving. A orbital tether might be better.

    @VanamondeThis thread should be moved to Kerbal Network.
  17. DAL59
    I agree. But, it is still very possible with current technology. Especially given that Mars landings were proposed with Apollo technology.
  18. DAL59
    With current technology, yes. We managed to land on the moon with 60s technology. With the technology in the 15th century, I'd still say Magellan had a more difficult voyage than a 21st century astronaut.

    Elon Musk had a reddit AMA and when asked about that ship in the middle, said that the city isn't necessarily accurate.
  20. DAL59
    Also, Neil de Grasse Tyson has just said something about early explorers vs. Mars mission: That makes sense. The sabatier reaction has been known for quite a long time.
  21. DAL59
    The microgravity duration will be less than on the ISS. And after the zero gravity, the transition is eased by only 40% gravity on Mars. It is not really an issue. They are sending an unmanned ship in advance with a fuel plant. Unless colonization takes place right away, more money has to be spent. On Mars, there is plenty of ice for water and oxygen. No need for closed loop. We have solar panels on Mars right now. Sure, they can get covered with dust, but you can just brush them off. The ISS gets half the radiation of interplanetary space. If duration of travel is 6 months(Musk says it will be less), then equivelent LEO time is less than a year. Scott Kelly and several russians have done longer stays than that.
  22. DAL59
    I've done that too. It didn't work. Especially since the heatshield blocked the descent engines. And I only had oxidizer at 50%. And the landing legs couldn't support the weight. And I forgot a ladder.
  23. DAL59
    Sure. So, where are the solar panels on the new version? He didn't mention them in the conference.
  24. DAL59
    To quote Elon Musk: "“You want to wake up in the morning and think the future is going to be great - and that's what being a spacefaring civilization is all about. It's about believing in the future and thinking that the future will be better than the past. And I can't think of anything more exciting than going out there and being among the stars.”"

    You found a NEW easter egg!!!!
