Exploration
Much human knowledge of Europa has been derived from a series of flybys beginning in the 1970s. Pioneer 10 and 11 visited Jupiter in 1973 and 1974 respectively; these first closeup photos of Jupiter's largest moons produced by the Pioneers were fuzzy compared to later missions.
The two Voyager probes traveled through the Jovian system in 1979 providing more detailed images of Europa's icy surface. The images caused many scientists to speculate about the possibility of a liquid ocean underneath.
Starting in 1995, Galileo probe began a Jupiter orbiting mission that lasted for eight years, until 2003, and provided the most detailed examination of the Galilean moons to date. It included, Galileo Europa Mission and Galileo Millennium Mission, with numerous close flybys of Europa.
New Horizons imaged Europa in 2007, as it flew by the Jovian system while on its way to Pluto.

And before that of exploration even.
John Smith remarked them as he coasted by....”

“The future author is one who discovers that language, the exploration and manipulation of the resources of language, will serve him in winning through to his way.”
