    That works but I sorry I don't like it. Why not do something then the likes of the constellation program? Why build the Hermes of you are only going to use it half of the trip. Honestly a crew could not last no matter how well trained in a capsule from Mars to earth. The only point of having something as large as the Hermes would be for efficency and the comfort for the crew. Again time really isn't a problem there is nothing wrong with being slow. If you wanted to get to Mars and back fast why not just huge chemical rockets?

    That was for Watneys escape. They couldn't slow down to get into Mars Orbit. They flew by and caught him, and the MAV needed to be heavily modified to get into a higher orbit and to match velocities. I think we are having three simultaneous conversations. Let me be clear I don't disagree with you about what would be better in real life I disagree with you about the feasibility of that infrastructure in the book and movie. Furthermore in real life I can't picture the program functioning like that. I mean we are talking about a little over a dozen SLS launches per Ares mission including one that would just have the crew? Im sorry that is prohibitively expensive. Yes it would take a very very long time to leave earths gravity like that in real life but NASA will easily trade time for money. Honestly that is better because it allows resources to go towards other things. Just to be clear I am talking about the feasibility of that idea both in the martian book/movie world and in real life.

    Congratulations!!!

    But what about from Mars orbit? I think either way it would take large amounts of time. So to save resources staying in LEO would be the most cost efficient. Launch several SLS to refuel and resupply the Hermes would be insanely expensive. Plus building the Hermes which I suppose could have been done in LEO and then pushed out to a Lagrange point but if it was built that far out would be unjustifiably expensive. I think all the money should go to NASA lol but realistically I'm just saying a project like that would be prohibitively expensive. So I think if we are cutting cost Hermes in LEO would be cheaper in terms of ressuplying and crewing at the cost of time to the crew escaping LEO at a snails pace. Again the issue is similar when the get to Mars. They aren't going to be to high of orbit at Mars because the higher they are the larger the MAV needs to be. So LMO would be optimal and could take a really long time to escape as well.

    Even in the book the Hermes Andy Weir mentions the Hermes is big and is parked in LEO also with the bomb Lewis was worried about their aerobreaking shape. Also the SLS is fine from earth the MAV would need to be huge to get back to the Hermes if it wasn't in LMO.

    Since when does that not mean that we need one?! I for one need a centaur stage for my Atlas V! It better be 1.875 and it better have a proper adapter decoupler 2.5 to 1.875. please please please recognize my sarcasm

    Nope I looked there is nothing indicating anything like that in the movie.

    Thats how the constellation program was planned. However I just don't see that with the way Andy Weir setup the Ares program in the book and it certainly doesn't look like that in the movie. I pictured a slightly modified version of the constellation program when I read the book. Fast forward to 5 minutes to see how they could land 2 rovers and an MAV. In the constellation program the MDV was the MAV too and had two rovers. Man I would have loved to see that program! http://youtu.be/uUBhn3_P3hU
  9. sp1989
    Right but that would make sense in the book. The rovers in the movie are quite a bit larger and an MDV with both movie rovers logistically would be enormous. Unless it was sent ahead like a constellation program. Unless they docked the front of the Hermes to the MDV with the rovers. Still if that's the case then why not go with the constellation program. Why would they launch to the Hermes in an SLS? That's a lot of rocket to dock to a ship in LEO. A Delta Heavy if they got it man rated would be a fine choice to launch a large Orion capsule to LEO even an Atlas V. If Space X has a space station why wouldn't they use what would most likely be a second or third generation dragon rider. I mean I don't mean to question Andy Weir but even he has to admit SLS to LEO is a bit much.

    I think the descent vehicle could be something like or an iteration of the Orion capsule. I mean if we are basing this on the movie, at the end they launch to the Hermes on a Delta Heavy. It was basically the launch of the EFT-1. Since we saw the Hermes on the way coming back to earth there was no sign of an MAV or an MDV or an MPCV attached I think we can a assume that the MDV is also the vehicle they launch from earth with. That would actually be a pretty efficient way of doing things.
  11. sp1989
    That's true even in the book the ship would need to have enough modules to perform the maneuver. Atleast 2 modules so that one could be sealed off and to get the explosive deceleration there would need to be quite large.

    I am not sure we can share certain websites but I found a good copy of the The Martian. Its still Cam copy but its steaming on a website that doesn't seem too sketchy. If you would like the link PM me. Maybe you can see parts of the Hermes that you might have missed.

    Also the Behomoth for some reason doesn't have trench smoke.
  15. sp1989
    Probably storage? It could also be a science lab?

    Its hard to believe that I was 10. My father rarely let me stay up and watch tv let alone on a Sunday night during school. I knew it was special when he let me stay up and watch it with him. I wish they would put that show on one of the streaming services or atleast back on hbo. I don't even think its on the HBOgo and that has almost everything HBO has ever produced.

    Can you make some of your science experiments give 100% transmission. I mean some of. It most of them are designed to be early iterations of probe experiments right? They never returned. So to only give some transmission doesn't exactly make sense.

    A deleted scene from the martian

    OMG I totally have faith in you Bob!! That is not what I meant at all!! I suppose i shouldn't have or needed to preface it all. I just wanted to say what I thought about the stock footage from NASA and the clip from "From the Earth to the Moon" would be a good idea. I apologize if you thought I was implying something different.
  20. sp1989
    I think it goes without saying that it would be in poor taste to reenact Apollo 1. I think the best way would be to mention it using memorial footage and stock footage of the aftermath. It an important part of the American space program however unfortunate. I don't know if you would be able to use it but I think you should use this or clips from this if you can. https://www.youtube.com/watch?v=V0W9bQ2Jg3A

    No that's the precisely the issue. They only appear closed. If you right click the radiators the option is retract. When you do that they open and then close.
  22. sp1989
    I thought that too. I guess I assumed because I looked at the stock bug fix and figured it would be there. Anyone if it's not VSPR issue then I still confirm the radiator issue.
  23. sp1989
    I can also confirm the radiator problem and also I have not noticed people reporting it but the heath shield shrouding goes missing after a revert to space center.
  24. sp1989
    I know I for one would definitely download it yes yes yes
  25. sp1989
    Sorry I read it wrong. The 411 iteration was the first Atlas V ever launched from Vandenberg.
