In May of 2001, the Athena Principle Investigator and MER Project Scientist assembled a board of scientists from the planetary community at large to review calibration procedures for the Athena science instrument payloads on the MER rovers. Separate reviews were held for the Pancam (multi-spectral camera), MI (microscopic imager), Mini-TES (thermal emission spectrometer), MB (Moessbauer spectrometer), and APXS (alpha particle x-ray spectrometer) Athena instruments. One of the recommendations of the calibration review board was for the measurement of the same well-characterized geologic samples by all Athena MER instruments. Such measurements validate (for the Athena team and the general scientific community) the primary instrument calibration and quality of measurement, aid in identification and solution of anomalies in instrument data returned from Mars, and enhance the ability of the scientific community to correlate interpretations of Mars data from one Athena instrument to another. Using flight instruments or engineering models of flight instruments, the Athena instrument teams are making measurements on 10 to 40 rock slabs that have been well characterized using laboratory instrumentation that includes the laboratory equivalents of the Athena flight instruments. A subset of these samples constitute blind test for the Athena instruments and science team. The laboratory data for the rock slabs, and for many other Martian analogue samples that are characterized in the same way as the rock slabs, form data libraries for the Athena instruments. Depending on Athena instrument, these data/spectra libraries have 200 to 2000 entries, and they extend libraries provided by individual Athena instrument teams.
