Nasas Juno spacecraft has provided the first close-ups of Jupiters largest moon in two decades.
Juno zoomed past icy Ganymede on Monday (US time), passing within 1038km.
The last time a spacecraft came that close was in 2000 when Nasas Galileo spacecraft swept past our solar systems biggest moon.
Nasa released Junos first two pictures Tuesday, highlighting Ganymedes craters and long, narrow features possibly related to tectonic faults.

This is the closest any spacecraft has come to this mammoth moon in a generation, said Juno’s lead scientist, Scott Bolton of the Southwest Research Institute in San Antonio.

We are going to take our time before we draw any scientific conclusions, but until then we can simply marvel at this celestial wonder the only moon in our solar system bigger than the planet Mercury.
Ganymede is one of 79 known moons around Jupiter, a gas giant.
Italian astronomer Galileo Galilei discovered Ganymede in 1610, along with Jupiter’s three next-biggest moons.
Launched a decade ago, Juno has been orbiting Jupiter for five years.
