Juno spacecraft is about to enter Jupiters atmosphere on July 4. The mission is expected to unveil the secrets of the giant planet but experts are worried about the harsh conditions on Jupiter. Can Juno survive?
Many don't know that aboard the solar-powered spacecraft are three aluminum lego mini figurines called "legonauts", as part of NASA and LEGOs Bricks in Space project.
NASA is expecting the mission to deliver tons of information from a planet believed to be formed as early as the Sun.
