MESSENGER's wide- and narrow-angle camera views
MESSENGER's wide- and narrow-angle camera views On approach to its third flyby of Mercury, MESSENGER snapped these views of the planet with its wide-angle camera (top) and narrow-angle camera (bottom) at nearly the same time. The wide-angle camera has a field of view seven times the width of the narrow-angle camera, at seven times lower resolution. NASA / JHUAPL / CIW
