Ganymede is an icy world hiding a salty subsurface ocean. Juno snapped the views during a close flyby on Monday. The craters and striated landscape features stand out in a shot from the spacecraft's JunoCam imager.
A second image from Juno's Stellar Reference Unit navigation camera shows the dark side of Ganymede and highlights some of the moon's many craters.
As more Juno data returns to Earth, researchers will be able to piece together a color portrait of Ganymede.
The flyby isn't just for the pretty pictures. NASA said Juno is studying the moon's "composition, ionosphere, magnetosphere, and ice shell while also providing measurements of the radiation environment that will benefit future missions to the Jovian system."
Juno, which launched in 2011, was originally scheduled to end its mission in July 2021, but will now continue its work until September 2025 or the end of its life, whichever comes first.
This first taste of Ganymede hints at the exciting visuals we have to look forward to. Onward, Juno.
