In case you missed it over the holiday weekend (busy watching fireworks? reading Donald Trump's tweets? Waiting for Hillary's indictment?) NASA successfully inserted the probe Juno into orbit around Jupiter, the gas giant planet. The Juno mission was launched in 2011, and has spent the last few years building up momentum among the inner, rocky, planets before slingshotting across three-quarter billion miles of space to rendezvous with Jupiter. A perilous 30+ minute burn of its main engine slowed it (from a speed of more than 40 miles per second) enough to enter a 53.3 day orbit. It then deployed the massive solar panels that provide the ~ 500 watts that power its array of sensors and transmitters. On October 19, the engine will fire again, dropping Juno into a 14-day orbit around Jupiter's pole, passing within a few thousand KM of the top of the Jovian atmosphere, and allowing the real science to begin. Its hard to overstate the technical challenges overcome by our engineers and scientists at NASA. After a journey of more than 2 billion miles, the burn time necessary to enter its initial orbit was within one second of that calculated. The dim sunlight that powers Juno's solar panels is less than a twentieth as intense as here on earth. The intense radiation around Jupiter is so great that its main sensors have to encased in a titanium vault. As it orbits Jupiter's polar regions, building up a mosaic of the planet's atmosphere, scientists hope to uncover many of the mysteries of the giant planet. Does it have a rocky core? When, in the genesis of our solar system, did the planet form? Its easy to become cynical about our society; our government; our species. But when you look at the marvels of projects such as Juno's mission to Jupiter, it gives me a great deal of hope for us all.
