PI: Dr. James C. Green University of Colorado at Boulder CoI: Dr. Cynthia Froning University of Colorado at Boulder N CoI: Dr. John R. Spencer Southwest Research Institute Y CoI: Dr. Nathaniel J. Cunningham University of Nebraska - Lincoln N CoI: Dr. Kandis Lea Jessup Southwest Research Institute N ------------------------------------------------------------------------------------ Abstract We will use six HST orbits with COS to observe the disk-integrated longitudinal distribution of IoΥs atmosphere, and ten HST orbits with STIS to provide complementary disk-resolved information at key locations. We wil use the COS G225M grating to observe four SO2 absorption bands, which can be used to determine SO2 atmospheric density. Disk-integrated 19 micron observations of the atmosphere indicate that the anti-Jupiter hemisphere of Io has an atmospheric density roughly ten times greater than the Jupiter-facing side (Spencer et al. 2005), and mm-wave observations suggest a similar pattern. However the infrared and mm-wave observations cannot easily separate atmospheric density from atmospheric temperature, so these results are model-dependent. Sparse 2100 Π 2300  disk-resolved observations (McGrath et al. 2000, Jessup et al. 2004) tell a consistent story, but do not cover enough of IoΥs surface to provide full confirmation of the long-wavelength result. We will therefore observe IoΥs disk-integrated atmospheric density at six longitudes, roughly 30, 90, 150, 210, 270, and 330 W, to confirm the 19 micron results and improve our ability to model the 19-micron data. With STIS, we plan disk-resolved 2000-3200  spectroscopy of Io's SO2 atmosphere. Our observations will target low-latitude regions away from active plumes (in contrast to our Cycle 10 observations (Jessup et al. 2004) which targeted the Prometheus plume), to look for the effect of plumes on the atmosphere. We will also look at the variation of low-latitude atmospheric abundance with terrain type, to look for explanations for the large longitudinal variations in atmospheric pressure to be studied with COS. Finally, we will look at a variety of regions at two different times of day to determine the extent of diurnal variations in the atmosphere, which are expected if the atmosphere is dominantly supported by frost sublimation. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will use the COS G225M grating to observe Io at six longitudes, roughly 30, 90, 150, 210, 270, and 330 W, for one orbit each. We will also use the STIS G230L grating with the 0.1" slit to observe the same low-latitude locations on Io for 5 orbits at each of two different central longitudes, roughly 200 W and 250 W, to determine the variation in SO2 abundance with time of day. 12041( 14) - 23-Aug-2011 17:34:59 - [ 2] Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- The STIS observations are treated as ten separate visits so that they can be shuffled as necessary to fit within the orbital longitude constraint- there may be room for 2 - 3 consecutive visits within a given rotation of Io. We are doing a diffuse acquisition for all the STIS visits because accurate pointing is critical. ------------------------------------------------------------------------------------ 12041( 14) - 23-Aug-2011 17:34:59 -
