First measurement of Mars uv dayglow, made during Mariner VI Mars flyby July 31, was reported in Science by Univ. of Colorado astrogeophysicists C. A. Barth, C. W. Hord, J. B. Pearce, K. K. Kelly, A. I. Stewart, G. E. Thomas, and G. P. Anderson; Johns Hopkins physicist W. G. Fastie; and JPL's 0. F. Raper. Emission features from ionized carbon dioxide and carbon monoxide were measured in 1,900 A to 4,300 A spectral region. Lyman alpha 1,216 A line of atomic hydrogen and 1,304 A, 1,356 A, and 2,972 A lines of atomic oxygen were observed. Prime objective of experiment was to search for nitrogen in Martian atmosphere. First analysis had shown no evidence of nitrogen emissions in uv spectrum of upper atmosphere (Science, 9/5/69, 1004-5)
