      <description>This volume contains tables of raw readings and reduced data from         
        all six runs on 01 August 1971 of the Lunar Self-Recording                
        Penetrometer (LSRP) on the surface of the Moon for the Apollo 15          
        Soil Mechanics experiment.  Supporting documentation includes             
        digitized scans in JPEG and PDF format of the original LSRP soil          
        mechanics dataset on microfilm, videos and transcripts of the LSRP        
        as it was operated on the Moon, diagrams and maps of the experiment       
        areas, and photography of the Apollo 15 Station 8 where the experiment    
        was performed. </description>
