How would a space program develop on the Earth-like moon of a gas giant?

Depends on the distance, but launching interplanetary probes would be more difficult. Since you have to both escape the gravity of the moon AND the parent planet.

I would find it more interesting to see how mythology and religion would develop in such a place. Bonus points if the gas giant has an "eye" like Jupiter... :lol:

It should be pretty obvious that the worlds are round, spinning on their axes, and spinning around the gas giant - unlike our one tidally locked moon, where you can't tell whether you are the centre of the universe or not without looking closely.
So, the giant-home-of-gods-is-the-centre-of-the-universe theory would probably persist for a long while, from antiquity well into scientific age.

For the rest - too much to guess.

Maybe we would be little teddy bears and would believe that a robot is a god?
 
Our school really needs to get :censored: together, school year 2012-2013 was the worst year i had, the chemistry teachers kept getting replaced by a new one, Because of this there was some topics that the old teacher left that the new one didn't even teach us, and worse it was included in the exams. We could have stu(died) but there was some topics that the teacher said that wasn't in our books. :facepalm:
 
Thats normal. My university teachers had the annoying tendency to leave for a better paid job at another university shortly before my exams. :dry:

I had something like that happen in my first Russian class in college: Our professor was very old and ended up having to take time off when her husband got sick and died. Before she came back, she got bitten by her cat and developed a really nasty infection, which kept her out for the rest of the semester, and the department had to juggle professors because they were now one short. I didn't take the next level of Russian in the spring semester, so I'm not sure if she ever came back, but I did hear that she died that summer.

True, but if the orbit was high enough, what about using the parent planet for a sling?

You could use the oberth effect to some extent, but to do a slingshot you have to come from outside its orbital frame, that's the whole point.
 
I think that there would be a lot more work on an "interplanetary" space program to explore the other moons, which would not need as much dV as it would to go to, say, Mars.
As for using the primary of the subsystem: depart downwell, and burn at periapsis relative to the gas giant. Boom, you've just multiplied your dV for a given fuel supply.

And to my knowledge, be lit up with radiation that would make Van Allen shudder.
(I don't know exactly where or when though, nor how probes don't get overwhelmed by radio interference)

Earlier ones weren't, and they got cooked. Galilieo was almost lost to melted tapes after a hit from a CME while headed to Jupiter, IIRC. Currently, they use shielded circut runs and, at least on Juno, a large "vault" for the sensitive electronics if it's truly critical. However, most spacecraft still aren't heavily hardened against radiation... it's too heavy.

However, if life did evolve in such an environment, perhaps they would have a much higher resistance to radiation.

I don't know how one becomes resistant to radiation without being a tree of lead. You can't really stop radiation from knocking your protons about, or wreaking havoc on genetic code that we're familiar with. But this is all for another thread (and more informed individuals than myself) probably. :P

:tiphat: Excellent idea! I may use that for my first program. Ive always wanted to do a sort of lunar lander/Orbiter/KSP mashup.
 
I'm just realizing that the pictures on xkcd's 'what-ifs' also have alt-text. And it is as hilarious as usual xkcd alt-text. :lol:
 
Now i'm expecting another "switch" in teachers next year, it happened last school year and this one..(the last one wasn't pretty as the subject this time was Algebra.. :dry:)

Though, i'd be prepared for Physics since this forum teaches me quite alot.. :lol:

I just hope its not trigonometry and stuff next year ;-;
