Apollo 17 Crew Debriefing for Science 1973

Summary

Three-page NASA document, doc number NASA-UAP-D005, titled Apollo 17 Crew Debriefing for Science, dated January 8, 1973, with the accession MSC-07632 and the Manned Spacecraft Center in Houston. The text is a scientific summary of mission results rather than an operational debrief. A speaker identified as Henry discusses ultraviolet, X-ray, and gamma-ray observations, including a search for red-shifted Lyman-alpha radiation from ionized hydrogen that set a lower limit excluding that hydrogen as the force holding the Coma cluster together, which he says may leave a real mystery. Other points cover the ultraviolet background measured at high galactic latitudes, whether the observed spectrum might be extragalactic, and the spectrum of the Earth seen from outside.
