This is really cool too. Gonna spend the rest of my evening learning stuff about jupiter and Io. I would have liked to do space stuff, but once I had to start doing algebra in high school I realised it wasn't for me. Like if I can't calculate how many fence panels Farmer John needs to cover an area of 500m square, I sure as hell can't work out space rocket stuff.
Math is really just something you need to make yourself learn if you wanna learn it. It's not some sorcery you need a magical aptitude for. Maybe you can't calculate how many fence panels John needs but if you put your head into it you'd learn how and you could also learn to understand space rocket math.

This was a interesting article.
http://www.wired.com/2013/09/plutonium-238-problem/

A lemons into lemonade sort of outcome was how due to the material shortage, NASA put in a good amount of effort into building a better RTG.

Of course even with a good design qual testing for some of newer concepts will delay them from being used.

I'm pretty sure that if it took 3 years for a mission to Jupiter, everyone would probably kill each other or suicide by the time they were 2 years of the way through

It doesn't matter if it's a gas cloud or a rock it weighs a lot and if you ignore what's on the inside it functions only kind of different from a big rock.

The magnetospheres of planets trap charged particles and protect them from solar winds. You might have heard of the Van Allen belt, that's earth's, but Jupiter is bigger and badder. And significantly less influenced by the sun.

One of its 67 moons, Io, has over 400 active volcanos and is about the size of our moon, ~1/10 the size of earth I guess technically it's more like 8% the size of earth. Its volcanos just casually dump up to 1 ton of poo poo per second 500km away from its surface and then jupiter pulls it in. Makes our moon look like a wuss moon, and it's a good comparison because it's the only other body in our solar system that's roughly the size of our moon.

67 moons? ya, jupiter stole a bunch of space junk while orbiting around because it's that drat big. It has 4 moons that are about as big as planets/our moon (one is bigger than mercury, get hosed mercury), 4 other moons that are moon-like, and then 59 "moons".

Thanks, great explanation!

All 4 of jupiter's big moons (Io, Europa, Ganymede, Callisto) are rad in different ways. Hope you learn some cool poo poo.

yeah taking pictures isn't one of the scientific objectives for this mission. it'll be way closer to the planet than any other craft has been so maybe we'll get a nice closeup though? idk

I think Hubble is gonna stay active until like 2025, there's a new one launching called the James Webb in 2018 that's gonna be able to smell alien farts in their atmospheres.

They're worried about the rocket blowing up on ascent and spreading radioactive material everywhere. It's a real risk but that's why NASA does detailed risk analysis and management on this sort of thing rather than just flying radioactive material around all willy-nilly like these people seem to think.

Some newer probes did also used RTGs but the main duel breaker was running out of reactor fuel.

NASA is working on more efficient reactors but all the new designs are currently in flight qual testing.

You've been selected to be fired into Jupiter's billowy embrace wearing a vintage 1980's spacesuit. The faceplate will most likely shatter a few kilometres after intersection with the cloud horizon. Your last few moments will be spent choking on thick noxious gasses while the streaming winds scrape open your eyes and whisper their frantic lullaby into your bleeding ears.
