The Space Sciences Center, directed by Darrell L. Judge, is engaged in both laboratory and space based investigations of photoabsorption and emission processes in atomic and molecular gases in the spectral region from the extreme ultraviolet through the infrared. Fundamental atomic and molecular constants and absolute specific cross sections are determined in the laboratory program using a broad range of experimental techniques. The deep space and sounding rocket flight experiments investigate the characteristics of planetary atmospheres, the interplanetary medium, and the sun through remote sensing optical techniques. Recently in situ neutral particle detection techniques have been developed to extend the capability of our remote sensing heliospheric space experiments. The Space Sciences Center also has a vigorous program in the physics of binary star systems and in the analysis of the luminosity variation of B and O type stars.
