Soil Mechanics Data Documentation on Microfilm


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1972-04-21 to 1972-04-24


This data set consists of one reel of 35-mm microfilm that contains tables and graphs with notes and corrections to the raw data on the characteristics of the soil sites in the Descartes region of the moon. The data are divided into four sections, A through D. Section A contains 10 graphs, one each for location designated as on index. The graphs depict penetrations (in centimeters) vs stress (in Newton/cm sq). The penetration varies from 1.8 cm (at index 16) at a stress of 1-6.5 Newton/cm sq to 74 cm at a stress of 3-120 Newton/cm sq (at index 6). Section B contains, for each index, calibration ratios or factors for Apollo 16 data reduction for penetration and load parameters, a load calibration curve for load (Newtons) vs drum circumferential deflection (millimeters), tables of lunar penetration data reduction with columns giving the drum load angle, drum circumference, load, stress, ratio of initial drum depth/final drum depth reading, and actual penetration depth. Section C contains the postflight calibration curves and tables in the same format as in section B. Section D contains the preflight calibration data.

The contents of this microfilm collection were scanned as part of the Lunar Data Project (LDP). The digital images (scans) are available as data collection PSPG-00749.
