If I recall correctly, they meant for the Q-thruster to be a form of RCS.

I can vouch for this. Perhaps you can do something similar in the Mission Control Room, but that's where you plan the maneuver nodes ahead of time from an orbit you launch into?

That day, December 7, 1972, we took one last trip to the Moon in the decade after the first. It will forever live on, Apollo 17, within our hearts. They travelled the great expanse, on a truly gargantuan vehicle, The Saturn V. They travelled for days to the Moon, and saw the most beautiful of sights, The Earth, Floating in the Ocean of Space, Under the stars. They landed the Challenger on the Moon, And would spend the most days on the Moon of any Apollo Mission. It was the last time we were out of the cradle, and now we're right back inside.

Well, it has been pretty much mentioned already. Three axes per stick. Yep. Although, the Up/Down translation would be done in a weird way.

A Sabre type intake. I know the principle of the thing, heck, the Pluto missiles were going to use them, but is it really practical? I mean, the thrust is going to be low because the heat transfer can only be done a few ways.

Hmm, interesting to note, if we simply stopped using so many Greenhouse gases, than eventually the Earth would settle down. You see, Humans evolved during the time where the Earth had the most climate change (I'm not saying Global Warming isn't true or anything) But, I have to say, there is more than just ONE greenhouse gas......

No, just, no. That's horrible. Killing people? That is never the answer, expand to space. Restrictions on birth? Yeah, 8+ kids is ridiculous, but I think that 6 living kids would be the limit (1 out of every three would die in car accidents unless we got rid of cars). Industries would have to resort to windmills and/or dams. Perhaps nuclear reactors. Again, if we build large space-based objects that can contain a small biosphere, than we could expand there temporarily, using reshaped asteroids and mined asteroids.

Hmm, perhaps when this happens, we will have reached the technological level to gain enough energy to strip the Carbon off of the CO2 molecules, and make it into O2, and then destroy the majority of cities (only small towns left, cities were a REALLY bad idea). Perhaps even return to hunter-gatherer situations, where it took 2000 calories to gain 2000 calories, and thus no "mass-produced" industrial fake food. No reductions in population (there is still plenty of room for now...... in places like the North American Great Plains and if we terraformed Siberia [somehow..?]) And I would also recommend the construction of O'Neil Cylinders, or large polyhedrons to have self contained biospheres (to at least have some sort of room for expansion and extra food)

Well, an Alcubierre Drive to LEO isn't practical, as the extreme gravity "wells" in front and in back would destroy, pretty much, almost everything.

Well, why would you need an intake like the Sabres unless you wanted to cool it down, which does increase its density. Perhaps it could get a slightly better Isp in atmosphere, but it wouldn't be extremely advantageous, because you get so little thrust......

Much of Luna, like the Oceans of Earth, have not been explored. So, who knows, maybe a new organic compound could be discovered (Organic compounds have been discovered on comets/asteroids). Or anything. Heck, there are possibly MILLIONS of species on Earth ALONE that we haven't discovered. Did you know, an entire patch of forest wasn't discovered till recently (early 2000s, even though satellites get "complete" coverage). I say we go to get experience with long-term stays on the surfaces of other bodies (like Mars). But, before we go on a full on expedition to Luna, we should at least do some more exploring here, even for a little bit of time.

Notice how I said effective exhaust velocity. Plus, you misspelled "would"

Tsiokovsky's equation had effective exhaust velocity, which is equal to: Isp (weight definition) multiplied by the gravitational constant of Earth. Interesting to note, that Tsiokovsky got his famous equation from the thrust equation.

That would probably cost too much heat energy, unless you brought a reactor. But, you said to cool it. On Mars, little cooling would be needed, if any.

Hmm, Perhaps another on the "New Nine"?

Sorry, I do that all the time....... I am really bad at not spoiling things.

So, you basically didn't put it into the equation, but you said it afterwards. It is in the original Tsiokovsky(probably spelled that wrong) equation, though. Isp is specific impulse, not exhaust velocity.

I was referring to the gravitational constant required for calculating D-v. Unless, by Isp you mean effective exhaust velocity.

Harry Turtledove- Worldwar. It's a good sci-fi book series, with (bear with me here) aliens invading during WWII (Turtledove does alternate history as well, so yeah). Turns out they invaded at just the wrong time. We end up destroying them, and a peace agreement is signed. Sort of... Then colonization. I don't know much of that, but it is during the 1960s. Now, the last book, is Homeward Bound. Basically, we end up getting some really advanced tech, outdoing the aliens, in less than a hundred years since they invaded.

Or perhaps add a text box, so you can put in *cough* exact *cough* values.

One fact not being considered is stability. A trailer type craft, where the engines "pull" the vehicle along, is more stable than a tractor, where it gets "pushed" So, Medusa is more stable.

May I say Contact by Carl Sagan? It was technically written DURING the development of the movie and came out beforehand. It is actually quite great. Unless someone already said that.

Wow. Just wow. I just think that the parts should be able to be constructed. That, or Kerbal-X. And, if they're to scale for that kerbal......

Magnesium salt-water? You separate the magnesium into a fine powder just before burning it. I'm kind of thinking ramjet here.

Umm, YES, it can. In fact, there was once a case were a mapping satellite saw a woman through a window. That woman, if I remember correctly, would sue the satellite guys. (I don't know which commercial organization)
