NASA's spacecraft Juno enters Jupiter's orbit

NASA spacecraft reached Jupiter on today after a five-year voyage to begin exploring the largest planet in our solar system. Juno was launched nearly five years ago on a mission to study Jupiter's composition and evolution. It's the first spacecraft to orbit Jupiter since Galileo. Galileo was deliberately crashed into Jupiter on September 21, 2003, to protect one of its discoveries a possible ocean beneath Jupiter's moon Europa.
The spacecraft's camera and other instruments were switched off for arrival, so there won't be any pictures at the moment it reaches its destination. Hours before the encounter, NASA released a series of images taken last week during the approach, showing Jupiter glowing yellow in the distance, circled by its four inner moons. Scientists have promised close-up views of the planet when Juno skims the cloud tops during the 20-month, $1.1 billion mission.
