Exploring Jupiter
Mankind has been studying Jupiter for more than 400 years. But we've only been sending spacecraft there since the 1970s! Nine spacecraft have visited Jupiter since 1973, and they've discovered a lot about the planet. Flip through the slideshow below to find out about these spacecraft and what they've discovered.
