Watch the king of the planets turn on its throne

As it orbits Jupiter, the icy surface of Europa heaves and falls with the changing pull of its parent planet’s gravity, creating enough heat to likely support a global ocean beneath the Jovian moon’s solid shell. Experiments by geoscientists suggest that this process, called tidal dissipation, could create far more heat in Europa’s ice than scientists had previously assumed.

Ground controllers have pressurised the Juno spacecraft’s propulsion system in preparation for a 5 July rocket firing by the probe’s UK-made rocket engine that will steer the spinning, solar-powered robot into orbit around Jupiter.

This is the final view taken by the JunoCam instrument on NASA’s Juno spacecraft before Juno’s instruments were powered down in preparation for orbit insertion.
