An overview of the 1985–2006 Mars Orbiter Camera science investigation more

The Mars Observer Camera (MOC) investigation was proposed in 1985 and selected in 1986 for the Mars Observer mission, a spacecraft that was lost enroute to Mars in 1993. Re-named the Mars Orbiter Camera, MOC was re-flown on Mars Global Surveyor and successfully provided more than 4 Mars years (between September 1997 and October 2006) of daily global meteorological observations and observed ancient, water-lain sedimentary rock, present-day impact cratering, and youthful gullies (some of which may be showing evidence for present-day liquid water), among many other results from its more than 243,000 images.
