[MALINETAL2001] describes the Mars Climate Orbiter MARCI; currently there is no published MRO- MARCI paper, but a paper describing the investigation is being written and may be included on future archive volumes. Instrument Overview =================== MARCI is a framing camera with a 1024x1024 pixel interline transfer CCD (Kodak KAI-1001) with 9x9 micron pixels. MARCI has two all-refractive 180-degree 'fisheye' lenses, one optimized for the visible and near-IR and one for the UV bands. The beams from these two lenses are brought to the CCD through a prism. A color filter array with seven dif- ferent bandpasses (five visible/near-IR and two UV) is directly bonded to the CCD. A typical image consists of seven 'framelets', each 1024 pixels wide and 16 pixels high, in each of these bandpasses. The visible bands can be optionally summed; the UV bands are always summed 8x8. The visible resolution from 300 km is about 1 km/pixel at nadir. The core of the MARCI electronics is a Motorola 56166 DSP, which interfaces to the spacecraft, generates the CCD clocks, and received digitized pixels from an Analog Devices AD1672 analog-to- digital converter. Both lossless and lossy image data compression can be applied by software running in the spacecraft computer. MARCI was originally designed for the Mars Climate Orbiter mission. For MRO, a separate subsystem, the MARCI Interface Adapter or MIA, was designed and built to translate the MRO command/data protocol into a form that could be interpreted by the heritage MARCI hardware.
