Automation of computer-aided astrometric reduction of photographs of satellites
Programs supporting the calculation of topocentric spherical coordinates of satellites from satellite images on negatives are discussed. Particular attention is given to a program for automatic identification of negatives obtained by the AFU-75 camera, and to the minimization of the amount of input information.

Determination of Planetary Basalt Parentage: A Simple Technique Using the Electron Microprobe
Previous studies have demonstrated the usefulness of major and minor elements in silicate phases to understand differences among basaltic systems and the influence of different planetary environments on basalt chemistry (e.g., Papike [1]). Intriguing data displays presented by Papike [1] include a plot of Mn vs. Fe (atoms per formula unit, afu) for pyroxene and olivine and a plot showing the anorthite content of plagioclase from different planetary basalts. Here we combine portions of these plots (Fig. 4) and provide all new data for olivine and plagioclase.
