Juno

Three LEGO figurines representing the Roman god Jupiter (right), his wife Juno (middle) and Galileo Galilei (left) as shown here will fly to Jupiter on NASA’s Juno spacecraft.

In case you missed it, NASA's Juno probe arrived at Jupiter a couple of days ago.

Juno is big, much bigger than the probe we sent to Pluto. With its solar panels extended it is bigger than a basketball court.

Juno weighed 4 tons at launch. Cassini (our probe to Saturn) weighed 6 tons and was the size of a school bus. Saturn is too far from the Sun for solar panels to be of any use, so it used a plutonium power source.
