The collection includes seventeen boxes. The documents in this collection cover the Mars Pathfinder Project from 1993-1997. Boxes 1 through 7 are Mars Pathfinder Science and Instruments material generated by John Wellman. Wellman's material consists of documentation generated on two of the three scientific instruments on board Mars Pathfinder; the Alpaha Proton X-ray Spectrometer electronics (APXS); an instrument mounted inside the rover where the temperature was controlled to determined alpha particles of a certain energy exposed to a radioactive source which looked at the energy spectrum of the alpha particles, protons and x-rays. The second scientific instrument was the Imager for Mars Pathfinder (IMP). This instrument primarily provided stereoscopic images via a Charge Coupled Device (CCD) camera with color capability. The stereo imaging system consisted of three main sections: camera head, extendable mast with electronic cabling, and two plug-in electronic cards. The data generated related to IMP design review, schematic drawings, test reports, meeting minutes and weekly status reports, calibration plans, rework and mod. package, magnetic properties, proposal information package and IMP investigation and technical plans. Tom Tomey's Science and Instrument System Engineering material, consists of boxes 8 through 16, and includes documentation representing flight rules, launch readiness review, camera drawings, IMP power profile, health checks, mass lien test, thermal issues, hardware certification, design file memos, IMP pyro cables and APXS rover electrical-parts list and rover interconnect diagrams. Also included is Tomey's data on the third scientific instrument on board Mars Pathfinder, the Atmospheric Structure Instrument/Meteorology Package (ASI/MET). This instrument had been given the task of taking data such as temperature and pressure for scientific analysis as well as, collecting data during descent and landing that provided information on atmospheric density, temperature and pressure at about 100 km down to the surface. The collection arrangement maintains the original uniformity as found. In boxes 1, 3 and 7 are the file title listing created by Wellman, and boxes 8, 11 and 14 are the file title listing created by Tomey. JPL Discreet materials: 2 folders are stamped "JPL Discreet." These have been moved to a box at the end of the collection, (Box 17). Their original position in the collection has been indicated with separation sheets. The entire files that are discreet are noted in the file folder list of the collection.
