NASA’s Juno mission has sent back its first two close-up images of Jupiter’s giant moon Ganymede, giving the public their first look at the moon’s surface in two decades. Juno made its flyby of Jupiter’s moon yesterday, June 7, marking the first time a spacecraft has gotten this close to Ganymede in more than 20 years, according to the space agency. Ganymede is the largest moon in the solar system and the only one of its kind known to possess a magnetic field.
