NASA’s Solar System Treks Project (https://trek.nasa.gov) is proud to announce that it has just released a new addition to its family of online interactive data visualization and analysis portals: Europa Trek (https://trek.nasa.gov/europa) focuses on one of Jupiter’s most intriguing moons. No spacecraft have yet orbited Europa, so we have a very limited amount of data on this fascinating moon. However, several probes have made key observations of Europa while making flyby passes of this moon, most notably NASA’s Voyager 1 and 2 probes in 1979 and NASA’s Galileo probe, which made multiple detailed flybys of Europa while orbiting Jupiter between 1995 and 2003. Europa Trek combines Voyager and Galileo data to allow users to examine the spectacular surface of Europa and conduct interactive flights over its remarkable terrain. In addition, Europa Trek provides a preview for upcoming missions including NASA’s Europa Clipper mission and the European Space Agency’s Jupiter Icy Moon Explorer (JUICE) mission.
