It incorporates several advanced technologies, including the use of graphite\/epoxy structural materials, 32\u2010bit microprocessors, 10<jats:sup>8<\/jats:sup>\u2010bit digital buffers, and high\u2010speed custom integrated circuits. The cameras use the \u201cpush broom\u201d technique to build pictures, one line at a time, as the spacecraft orbits the planet. The narrow\u2010angle camera can acquire images of areas ranging from 2.9 \u00d7 2.9 km<jats:sup>2<\/jats:sup> to 2.9 \u00d7 25.2 km<jats:sup>2<\/jats:sup> at a resolution of 1.4 m\/pixel. Additionally, lowerresolution pictures (to a lowest resolution of about 11 m\/pixel) can be acquired through the narrow\u2010angle camera by pixel averaging; these images can be much longer (up to 2.9 \u00d7 500 km at 11 m\/pixel). The wide\u2010angle cameras are capable of viewing Mars from horizon to horizon and, in a single 24\u2010hour period, can acquire a complete global image of the planet at a resolution of at least 7.5 km\/pixel. Regional areas (covering hundreds of kilometers on a side) may be photographed at a resolution of better than 250 m\/pixel at the nadir. The two wide\u2010angle cameras image through a different spectral filter, allowing the construction of color images. The MOC is a cylinder 88 cm in length and about 40 cm in diameter; the redundant electronics, equivalent in complexity and computational power to two engineering workstations, fit within a volume 40 cm in diameter and 10 cm long behind the narrow\u2010angle primary mirror. NASA's Mars Observer mission has adopted a distributed operations philosophy: all uplink and downlink activities for the MOC and the other payload experiments will occur remote from the Jet Propulsion Laboratory's command centers. Following its year\u2010long flight to Mars (launch is scheduled for 16 September 1992), Mars Observer is planned to acquire data for one Mars year (687 Earth days). During that time, MOC will acquire about 2 \u00d7 10<jats:sup>12<\/jats:sup> bits of image and engineering data. During the last three months of the mission, Mars Observer will use a French\u2010supplied relay system to acquire an additional 2 \u00d7 10<jats:sup>9<\/jats:sup> bits of data from balloons deployed as part of the Soviet Mars '94 mission. These data will be collected and transferred to the Earth through the MOC electronics.<\/jats:p>","DOI":"10.1002\/ima.1850030205","type":"journal-article","created":{"date-parts":[[2007,3,5]],"date-time":"2007-03-05T22:50:12Z","timestamp":1173135012000},"page":"76-91","source":"Crossref","is-referenced-by-count":32,"title":["Design and development of the mars observer camera"],"prefix":"10.1002","volume":"3","author":[{"given":"M.
