What better way to crown the Fourth of July, a celebration of the birth of the U.S.A., than to plunk a billion-dollar spacecraft—Juno, the fastest-moving probe ever launched by humanity—into a perfect orbit around Jupiter? This isn’t just any orbit. NASA had to thread Juno into a precise path taking the craft between the planet’s upper atmosphere and its hellish radiation belt. Too close to that belt, and the instruments would have been instant toast. Fortunately, NASA eats challenges like that for lunch. Juno will be flying a highly elliptical path over the huge planet’s poles, zooming repeatedly to within a few thousand miles of the atmosphere and then whipping way out for a long-distance view.
Like so many space stories, there’s a lot in this that echoes my current work in progress. Readers of The Chaos Chronicles might remember that Li-Jared comes from Karellia, a planet with a fiery radiation belt surrounding it. In The Reefs of Time, Li-Jared (and we) get a chance to visit that world, which features things even weirder than the “beautiful, perilous sky” that its inhabitants know so well.
Take a moment to enjoy this view of Jupiter’s moons circling the great planet, shot by Juno on its flight inbound.
