Exploratory Missions:

Pioneer 10 -- 1973 did a flyby of the Jovian System. These were the best photographs it took of Europa.

Voyager 1 -- 1979 did a flyby of most of the outer planets. Voyager 1 and 2 only took detailed photographs of small portions of Europa and they were in high sun so it was difficult to see relief.

Voyager 2 -- 1979 did a flyby of most of the outer planets

Hubble Space Telescope -- 1995, ongoing photographs being taken. Hubble will be able to take photographs regularly to try to follow the changes in the surface features and processes that go on.

Galileo Mission -- 1996

Science Objectives (from JPL page )

Europa was poorly imaged by Voyager so the plan includes a mix of high resolution and low resolution observations to provide context.

Europa Ice Clipper Proposed Mission ( Astrobiology Website ) -- The overall science goal for the Europa Ice Clipper is to sample the surface of Europa to understand the processes that shape it and to look for evidence of a subsurface ocean. In addition it will address questions as to the formation of Europa and the source of water for the Galilean satillites.
