When will manned missions to Jupiter and the other outer planets happen, Veeky Forums?

To clarify:
Obviously the OP pic is a fantastical representation, as the crew would be fried by radiation being so close...
But it seems like a waste to focus on just the Mars meme when there's so much clay out there.
What gives?

>manned missions to Jupiter
Why? The moons are of more interest for humans to land on. But, everything can be done via robots. The only reason humans should go anywhere is to colonize and that is super difficult with most of the stuff in the system. Manned bases aren't even needed since robots can do everything there as well.

haven't we already sent like a module or something there?

Solar is useless past mars.
TRGs don't put put enough power.
You need a fission reactor for manned flight past mars.

>Solar is useless past mars
Nonsense. One could argue that Mars is a dead rock and a moon like Europa might even have life.

solar panels are useless past mars, because there simply isn't enough solar energy.
at earth. you get 1 kilowatt per meter squared. at mars it is 500 watts per meter squared.
your best solar panel is 46% efficient under ideal conditions. so on earth you are getting 460 watts per m^2, and 230 watts per m^2 on Mars.
jupiter gets 50 watts per m^2. so a solar panel would get you 23 watts per m^2.
Juno is solar powered and orbiting Jupiter. though this is fine for a probe. where the power budget was carefully calculated before it even took off.
manned vessels would have a much greater energy requirement.

Really? Don't they use ionizing radiation from fast decaying radioactive elements like plutonium or something in order to simulate the mechanism of solar panels? The so called atomic batteries?

Thermonuclear Radioisotope Generators.
They're great if you need a little bit of energy for a very long time. Which makes them great for probes and rovers.
You want to keep humans alive and comfortable. You need tens/hundreds of kilowatts of power a day.
apollo missions had 3 hydrogen fuel cell stacks just for the command module. each one produced 500-2300 watts. they only lasted for 8 days and supported 3 people in austere conditions.

Can't Jupiters radiation be somehow used to generate/store useful energy?
