Mars Color Imager
open-in-new
<p>The Mars Color Imager (MARCI) is a wide-angle, relatively low-resolution camera built for <i><a href="/facts/Mars_Climate_Orbiter/4ef8hLnm">Mars Climate Orbiter</a></i> and <i><a href="/facts/Mars_Reconnaissance_Orbiter/7odg7YfX">Mars Reconnaissance Orbiter</a></i>. MARCI views the surface of Mars in five <a href="/facts/Visible_light/jeofpMn4">visible</a> and two <a href="/facts/Ultraviolet/kncBUqn5">ultraviolet</a> bands. Each day, MARCI collects about 84 images and produces a global map with pixel resolutions of 1 to 10 km (0.62 to 6.21 mi). This map provides a weekly weather report for Mars, helps to characterize its seasonal and annual variations, and maps the presence of water vapor and ozone in its atmosphere. The camera was built and is operated by <a href="/facts/Malin_Space_Science_Systems/GtgxIykE">Malin Space Science Systems</a>. It has a 180-degree fisheye lens with the seven color filters bonded directly on a single CCD sensor. </p>
