Europa Clipper's visible-light camera system From Wikipedia, the free encyclopedia
The Europa Imaging System (EIS) is a visible spectrum wide and narrow angle camera on board the planned Europa Clipper mission that will map most of Europa at 50 m (160 ft) resolution, and will provide images of selected surface areas at up to 0.5 m resolution.

EIS will provide comprehensive data sets, including cartographic and three-dimensional geologic maps, regional and high-resolution digital topography, geographic information system data products, color and photometric data products, a geodetic control network tied to radar altimetry, and a database of plume-search observations.[3]
EIS combines a narrow-angle camera (NAC) and a wide-angle camera (WAC) designed to address the reconnaissance goals. Both cameras operate on the visible spectrum (390 to 700 nm) and make use of push broom scanners for obtaining images with stereoscopic sensors.
The Principal investigator is Elizabeth Turtle.
The objectives of the EIS instrument are: [3]
The NAC provides very high-resolution, stereo reconnaissance, generating 2 km wide swaths at 0.5 m pixel scale from 50 km altitude. NAC observations also include: near-global (>95%) mapping of Europa at ≤50 m pixel scale; regional and high-resolution stereo imaging at <1 m/pixel, and high phase angle observations for plume searches.[3][4] The NAC will also perform high-phase-angle observations to search for potential plumes, even when the spacecraft is distant from Europa.[4]
The WAC will acquire stereo reconnaissance, generating digital topographic models with 32 m spatial scale and 4 m vertical precision from 50 km altitude.[3][4]
