SSI
is a high-heritage copy of the MPL SSI and of the imager
for Mars Pathfinder [66], which returned nearly 17,000 images.
The original charge-coupled device (CCD) will be replaced
with a higher resolution CCD of MER heritage. SSI
receives a command to take an image that moves the azimuth,
elevation, and filter wheel motors. The CCD is exposed and
the image data is transferred to the frame buffer board.
The RS-422 high-speed serial interface is used to send the
data to the lander computer. SSI flight software,
onboard the lander, processes the image and transfers it
to the telemetry buffer for downlink. SSI surveys
the landing site for geological context, provides range
maps in support of RA digging operations, and makes atmospheric
dust and cloud measurements from its location 2 m above
the ground. Two "eyes" allow stereoscopic imaging
in blue, red, and near infrared. Filters allow imaging at
12 wavelengths of geologic interest and 8 of atmospheric
interest. Once the spacecraft has landed, the first
product will be a panorama in full color with red stereo.
The images will be compressed to make the panorama. Stereoscopic
images of the digging area will be used to produce digital
elevation models (DEMs); multispectral images will be used
to identify local minerals. Additional multispectral
images around the site will be taken to fill available downlink.
Sun
images will be used to obtain opacity; sky images
will be used for aerosol and dust/cloudproperties. Lander
