You can find topics related to mission scenario on the topics-page exactly for such studies...

I don't have a scientific background, but what would be the feasibility/marginal utility of sending a satellite out with the aim of being in permanent orbit of Jupiter?

Perhaps designed to be small and modular so it could eventually be built into a permanent space station, as well as a means of transmitting data back to Earth?

I think the key thing about this mission is to think in terms of permanence and modularity, even if we do not see how it is possible yet. It would be good to have a safe and contained environment circling Jupiter to send people back and forth. Mars as a halfway point seems like a great idea too.

Perhaps a first point for brainstorming would be to create a list of what will stand in our way technologically, and then figure out ways to overcome those issues. Power and radiation seem to be the major brick walls.

Are we certain that the type of people that would agree to a one-way mission are in fact the best people to send to carry out such complex work?

Also, do we want to set a precedent that whenever we decide that for future problems humanity faces, that instead of finding a way to at least potentially bring our people back, we instead take the easy way out and find humans willing to die for our needs.

We're building robots to help clear out radioactive site like Chernobyl and Fukushima. It would be much easier to sacrifice a group of humans to go in there and fix the problem, and it would likely be better in the long run to fix the problems sooner rather than later. I'm sure we could find someone who lost their family, and convince them to make such a sacrifice in honor of their loved ones. I do not see that as ethical.

However, the astronauts are dying slowly of suffocation and starvation, instead of a quick death as in wars, (And suffocation is truly painful.)

I don't think that we should have them die like that. I support the idea that if it's one way, they should at least have supply shuttles coming every five years and be somewhat self sufficient, as in a colony, and have a means to return in the timeframe of two decades.

A one way mission to Europa isn't exactly a death sentence, if it is executed well and, with enough luck, we will have a true colony

A crewed mission seems far too complicated and expensive for this kind of project. More importantly, I think it is premature. It would be a voluntary suicide mission with relatively minor results. Within a few decades after such a mission occurred, we might have discovered a new mechanism for propulsion or some other technology that could have made the journey quicker and safer.

Although we are much further along than we were several decades ago, I think the technology to actually create a feasible and effective manned mission just isn't there yet.

I vote that this project begin with a proof-of-concept. Land a vehicle of some kind on the surface that can act as a relay/communications station for any future mission. Take some pictures from the surface. Prove that the crowd-funding approach can work. Trust me-if it succeeded-it would get enough attention to generate funds for a second mission.

Precursor missions are also a part of OE 😉 A manned mission is the main aim.

I agree that a manned mission should be the ultimate goal, with the caveat that we either return our explorers or enable colonization. I see no scientific gain in a one way crewed suicide mission.

Guys, it is very big idea, great target for life of human, but lets be objective - now humanity can't do this. I am ready to devote my life for colonization Europe, Mars or Moon, it is very interesting, but it's not interesting to fly over 600 days, see Europe and die. Such act bring only tear for my mother and nothing useful for humanity. We havn't enouth knowledge and technologies for this journey now.

most, the estimated journey with modern technology is ~6 months. This is roughly 180 days. Also, the technology being used on this vessel will be a collaboration, and will be improved compared to previous missions. The mission of this project is to gather the knowledge needed, along with the technology, to make this happen.
