Mars Pathfinder Imager Collection, 1997.

http://www.worldcat.org/oclc/733100803

The collection includes four disassembled three-inch binders of the IMP (Imager for Mars Pathfinder) surface operations, specific sequences of the IMP projected run time, engineering uplink overviews, science sequence of events showing a timeline of science activities and guidelines and constraints for the Mars Pathfinder Imager from July - September 1997. The volumes were numbered with prefixes JPL document number 15722 Volume 1 sol 1- sol 4, and JPL document number 15723; Volumes 1-3; sol 14 - sol 94. (Note: Volume 1 of 3 does not start until sol day 14). The disassembled binders are here arranged by tabs in a chronological order that separate the volumes as originally sequenced by Martian days, called "sols," (named after the Roman God of the Sun). Mars turns on its axis once every 24 hours, 37 minutes, making a Martian day slightly longer than a comparative Earth day. The IMP lander camera did not record its images on film. Instead, light traveled through a window, reflected off mirrors and prisms, passed through filters and lenses and was projected onto a side -by-side charged -coupled device (CCD). The imager was in a barrel-shaped housing which sat on top of an extendable mast that stretched 62 cm above its stowed position upon deployment and approximately 150 cm above the surface of Mars. The best focus of the camera was at 1.3 meters; the depth of the field ranged from 0.5 m to infinity. The imager returned 16, 661 images, including enough frames to produce 360-degree panoramas of the landing site.
