摘要

Hello again, old friend. NextJuly, NASA's Juno spacecraft will go into orbit around Jupiter. It will be the first craft to go there in over a decade, and we've got a lot of catching up to do. As the largest of the eight planets, Jupiter has played a crucial role in shaping the solar system. Like the sun, it is mostly made of hydrogen and helium, but sniffing out the sprinkling of other elements inside could solve the long-standing mystery of how the planets formed. Many spacecraft have whipped past Jupiter en route to elsewhere, but Galileo spent eight years exploring the gas giant and its moons. One big surprise was that it picked up only trace levels of water vapour. Oxygen is the third most common element in the universe, so Jupiter was expected to have a fair amount of it locked up in water, maybe even as much as 20 Earths' worth.
