Great Canadian Fireball Procession of February 9, 1913 from contemporary newspaper accounts
Geological setting of Surveyor 7 Tycho landing site, including rock types
Lunar surface particle size distribution visible around Surveyor 1 site, comparing values with theory and industrial grinding processes
Geosyncline formation in earth crust by deposition of sediments in shallow water
Chemical element abundances for common rock types compared with preliminary chemical analysis of lunar surface at Surveyor 5 landing site
Lunar surface data from recordings of Surveyor probes evaluated for existence of chondritic meteorites
Lunar soil chemical analysis and magnetic measurements by Surveyor 5 agree on basaltic composition
Tektite classification by type based on external form, attributing surface sculpturing of type B to aerodynamic and not chemical processes
Strain birefringence around tektite surface notches, discussing specimen quenched in air stream from 1000 degrees C
