Objectives of program were to obtain photographic coverage of potential Apollo and Surveyor landing sites on moon and information on gravitational field of moon; landing site search at 1-m resolution was essentially completed by end of third flight; remaining flights provided 100-m resolution map of lunar front side and closeup views of scientifically interesting sites; lunar orbit design is developed in terms of mission requirements and predicted effects due to Earth and lunar gravitational fields; errors experienced in predicting spacecraft trajectory during flight are indicated to be due to large irregularities in lunar gravitational field.
