18-22 March: The Fifth Annual Lunar Science Conference, at Johnson Space Center, was attended by more than 550 lunar scientists from the U.S. and several foreign countries. Some 200 papers were presented on the lunar regolith, interior, crust, impact effects, mare basins, and the interchange of material and energy between the moon and its environ-ment.
Dr. A. Albee, California Institute of Technology scientist, said that analysis of an Apollo 17 lunar rock sample indicated that the sample was 4.6 billion yrs old and an example of a very early differentiate. The study suggested that the lunar crust formed very early in the evolution of the moon by extensive melting associated with differential, gravitational separation of various other rock types.
The Conference showed the trend among lunar scientists had been shifting away from the initial dating and chemical analysis of rock to cross-discipline studies of possible implications of the lunar samples to understanding of solar system chronology.
