New "Juno" Mission To Jupiter Announced
Riding with Robots writes "Today NASA announced it is officially proceeding with the Juno robotic mission to Jupiter. Scheduled to launch in August 2011 and reach the largest planet in 2016, the spacecraft will orbit the planet 32 times, skimming about 4,800 kilometers over the planet's cloud tops for about a year. The mission will focus on Jupiter's structure and evolution, and not on Europa or the other icy moons that may hide oceans under their surfaces — a disappointment if you ask me. Then again, all planetary missions so far have turned up amazing images and surprising scientific discoveries, and I doubt this expedition will be any different." We discussed NASA's deliberation of its short list a few days back.
Based on what we do (don't) know, I'd say we can learn a lot more from Jupiter than Europa.
Our understanding of Jupiter and other gas giants is really lacking. The only hope of discovery of any kind on Europa is life. But that is a really small chance, and therefore a very big gamble compared to the large set of questions we know will be answered by starting to explore Jupiter.
Modding me -1 troll doesn't make me wrong.
...or just possibly NASA hasn't forgotten that their mandate includes far more more than chasing after the tantalizing hope of extraterrestrial life.
Most of the researchers there are certainly interested in the potential for life, but ultimately the "possible signs of life" banners are there to keep people interested. I'd love to see more of my tax dollars go towards probing every single body in this system - not to look for what may be useful decades or centuries later, but just to see what's there - which usually gives more interesting results.
Some day, maybe within our lifetimes, a probe will be sent to a nearby star, regardless of how many years such a mission would take. That mission will be expensive, and it will require public support. The ideal pitch is that it would be our very first foray to another star - a significant event in human history in itself. Judging by the past few decades, though, they'll have to resort to "Could There Be Life At Centauri" or similar talk. Sometimes it takes sci-fi dreams to get most people to support basic science.
Do not confuse "Freedom of Choice" with "Free Will".
It's only going to have so much fuel, and it may need all of it to get the 32 orbits you're complaining about. Once that's gone, there's no more maneuvering. And, of course, we'll still be able to get data back as it drifts out of the Jovian system. It's not like it's going to go dead the moment that last orbit ends, you know.

I detect unwarranted high levels of snark in this post. The Sun is too hot for chemical reactors and stable solid matter. Jupiter is not.
1) So does that mean it will be in a sun synchronous polar orbit at Jupiter? Won't that compromise the data collection opportunities it has? (It'll never be able to look "straight down" with the sun at its back).
Do you think a 767 at cruising altitude casts a significant shadow on the surface of the Earth? At these kinds of distances the effect is too diffused to even notice.
