Juno took this picture of Jupiter’s Moons on June 21:
Here is a video overview of the project:
This video is about the spacecraft technology:
The spacecraft will spend two years on scientific studies including measurements of Jupiter’s magnetosphere, gravity, atmospheric composition, and more.
Juno is the first probe to the outer planets to rely solely on solar power rather than using a radioisotope thermoelectric generator.
