"NASA's Juno mission has already made mincemeat of precedents and expectations. When it arrived at Jupiter last July after a five year journey, it was further from Earth than any solar-powered craft had ever been, and traveling faster than any other human-crafted object had before. Its flight path skims closer to the storm-torn gas giant than any orbiter preceding it. And it's the first spacecraft to pass over Jupiter's mysterious poles—finding, counter to most assumptions, that they're blue, and lack the planet's characteristic stripes.

Juno isn't done with firsts, or with sending scientists back to their whiteboards. Scientists have been poring over the data Juno collected in its first cloud-grazingly close pass over Jupiter last August, and today published two papers on what they've discovered about Jupiter's auroras, atmosphere, and magnetic and gravity fields. And not only are Jupiter's atmospheric dynamics less Earth-like than scientists thought, they're also far more complex and variable. That means if scientists want to fully understand planets, a single probe might give incomplete, misleading information. Luckily for Jupiter scientists, Juno—with its many, closely spaced orbits designed to map the whole planet—is the right tool for the job…"
