Mariner 9 ultraviolet spectrometer experiment: measurements of the Lyman alpha sky background

Journal Article · · Astron. Astrophys., v. 28, no. 3, pp. 323-326
OSTI ID:4335256
During the flight of Mariner 9 to Mars, the ultraviolet spectrometer on board the spacecraft measured the L alpha intensity for several points in the sky. These data are compared with a sky map obtained by OGO-5 and the observations of Mariner 6. The absolute calibration of Mariner 9 and Mariner 6 differ by a factor of 1.43 at L alpha . The low values of the sky brightness measured bv Mariner 9 near the sky minimum suggest that the nearby interstellar medium has a kinetic temperature of 200 to 1100 deg K and a relative velocity with respect to the Sun in the range 13 to 14 km s/sup -1/.
