Before its encounter with Jupiter, NASA shut down all the instruments aboard Juno, save the few communications ones it would need to execute the flyby on battery power. Before that, though, the JunoCam instrument managed to make a movie.
On approach, the cam took dozens of consecutive shots of Jupiter’s four largest moons in orbit around the planet. Io, Europa, Ganymede, and Callisto are all visible in the film, though none of the other 63 are. (Amalthea, an irregular moon about 250 km at its widest, is one of three moons smaller than Europa but larger than 100 km in the system, and the rest are remarkably small.)
The JunoCam itself may not be long for this world. It’s expected to last seven to eight orbits before the harsh radiation of Jupiter disables it. It also may not get much of a look at the moons, instead focusing on the cloud layers where the Juno craft will be swooping closely by.
