| 内容記述 | 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 by Mariner 9 near the sky minimum suggest that the nearby interstellar medium has a kinetic temperature of 200-1100 K and a relative velocity with respect to the sun in the range 13-14 km/sec. |
