Proposal_Information Title: IMAGING THE ATMOSPHERE OF TITAN AND ITS SURFACE Proposal_Category: GTO/OS Scientific_Category: Solar System Cycle: 5 Investigators PI_name: John Caldwell PI_Institution: York University CoI_Name: Peter Smith CoI_Institution: University of Arizona CoI_Name: Mark Lemmon CoI_Institution: University of Arizona Abstract: This program will image Titan from the ultraviolet to the near infrared to observe seasonal effects in the atmosphere, to search for cloud features that may be used as wind tracers, and to fill in longitude gaps in coverage of surface features from a previous program. Questions Observing_Description: Observing Titan in the correct orbital longitude range is critical. See below. Additional_Comments: This program consists of five visits to Titan for imaging. There is a choice of three epochs for making the observations, but once the epoch is chosen by the STScI, the relative timings of the orbits must be preserved, within specified limits. The first preference is to do the observation close to the opposition of Saturn, in late September, 1995. The second and third choices are to do it in early October or in early September. The possibilities are given below: FIRST OPTION (All dates 1995) (Orbital longitudes measured from superior conjunction) Visit 1 Orbital Longitude 010 deg Sep 15 18.5H +/- 6H Visit 2 Orbital Longitude 110 deg Sep 20 13.5H +/- 6H Visit 3 Orbital Longitude 137 deg Sep 21 13.5H +/- 6H Visit 4 Orbital Longitude 165 deg Sep 22 13.5H +/- 6H Visit 5 Orbital Longitude 270 deg Sep 27 13H +/- 50H (+/- fifty hours) SECOND OPTION Visit 11 Orbital Longitude 010 deg Oct 01 16H +/- 6H Visit 12 Orbital Longitude 110 deg Oct 06 11H +/- 6H Visit 13 Orbital Longitude 137 deg Oct 07 11H +/- 6H Visit 14 Orbital Longitude 165 deg Oct 08 11H +/- 6H Visit 15 Orbital Longitude 270 deg Oct 13 11H +/- 50H THIRD OPTION Visit 21 Orbital Longitude 010 deg Aug 30 23H +/- 6H Visit 22 Orbital Longitude 110 deg Sep 04 16H +/- 6H Visit 23 Orbital Longitude 137 deg Sep 05 16H +/- 6H Visit 24 Orbital Longitude 165 deg Sep 06 16H +/- 6H Visit 25 Orbital Longitude 270 deg Sep 11 16H +/- 50H NOTE THAT THE FOLLOWING SETS OF 5 VISITS WOULD ALSO CONSTITUTE AN ACCEPTABLE PROGRAM: 5, 11, 12, 13, 14 OR: 15, 21, 22, 23, 24 THE SAME SCIENCE WOULD BE DONE BECAUSE THE SAME ORBITAL LONGITUDES WOULD BE COVERED. THESE POSSIBILITIES ARE IN FACT COVERED BY THE DEFINITIONS OF THE TIME WINDOWS IN THE EXPOSURE LEVEL SPECIAL_REQUIREMENTS.

Only five of these visits will actually be executed. The executed program will cover a range of Titan longitudes during one revolution of Titan around Saturn. There is not much preference between them, so any operational advantage, such as SAA avoidance or whatever, would be enough to choose one option over the others. ALSO NOTE THAT COMBINATIONS OF OPTIONS ARE POSSIBLE, as described in "additional comments". Visit_Comments: Orbital longitudes of Titan are critical, although there is reasonable tolerance.
