JunoCam’s four images of Europa have been projected into cylindrical maps by Gerald Eichstädt, and here they are combined into a map with some features labelled. The general texture of ridges and bands and chaos regions is ubiquitous on Europa, but much of this area has not previously been imaged so well. Impact features are rare: this map shows one large one (Callanish, which was viewed at high resolution by the Galileo orbiter), and possibly a small one (Midir, not yet viewed at hi-res). White arrows indicate features that Paul Schenk and colleagues have argued may be signs of global stresses due to polar wander (global rotation of the crust), so this image adds significantly to that discussion. Gerald’s original maps, as well as a larger-scale, unlabelled version of this one, are in the ‘Think Tank’ pages.
