After the occultation itself, which occurs at 17:45, CIRS will obtain limb integrations using their FP3 detector array at the occultation latitude as well as at locations 5 deg to the north & south. At each latitude, 2 pointings are necessary to provide sufficient vertical coverage. VIMS_164RI_EG60PHASE001 ..... 2012-114 ..... 62 Mb 11 hr observation of Saturn's tenuous E ring, to characterize its IR spectrum, vertical structure and phase function. Simple stare at both ansae of the ring for 5.5 hrs each. VIMS_165ST_TRANSIT001 ..... 2012-116 ..... 94 Mb VIMS will observe a primary transit of the exoplanet HS 189733b, in an attempt to detect the spectral signature of the planet's atmosphere. The transit duration is approx 106 min, and we will also obtain a similar period of "calibration" observations of the star both before and after the predicted transit time of 2012-116T16:12 - 17:58. Total allocated observation time is 7:00 & on-target time is 6:30. The "umbral" phase of the transit, between 2nd & 3rd contacts, is only 59 min in duration. Observation design will be the same as for the rev 159 TRANSIT attempt in S69: continuous 2*2 hi-res cubes with 500 msec integration time, to provide local sky background and some insurance against known pointing uncertainties. NO_BACK mode, with Z_OFF = 30 & X_OFF = 31. VIMS_165SU_SOLARPORT001 ..... 2012-122 ..... 55 Mb Calibration observations of the Sun thru VIMS' solar port, to monitor variations in instrumental sensitivity and/or the solar spectrum. Also used to carry out experiments for the Venus transit observation in S76, varying the cube size and integration time. One set of 1000 6*6 cubes with x_0 = z_0 = 28. Duration = 3:00. ***** IN-1 starts on 2012-143 ***** VIMS_167RI_COMPDARK001_PIE ..... 2012-156 ..... 35 Mb This is one of the highest-resolution opportunities in the XXM to obtain VIMS spectral observations of the unlit (dark) side of the rings. At a range of 410 kkm, the standard VIMS resolution is 200 km/pixel. The relatively high phase angle of 130 deg means that tenuous, dusty features will be highighted. We will target two positions in the rings, both along Saturn's shadow in order to minimize the effect of scattered light from Saturn itself. First we will look at the middle A ring, including the Encke gap with its narrow, dusty ringlets, and then at the outer C ring & innermost B ring. The scientific goal is to learn how the spectral contrast between narrow features in the rings differs between the lit and unlit sides of the rings. This observation falls in a Custom Turn period. Duration = 1:02. VIMS_167SA_USUNOCC001_UVIS ..... 2012-157 ..... 65 Mb VIMS rides along on a UVIS Saturn solar egress occ, at latitude +36.1 deg. This solar occ is unusually close at 3.9 R_S. Integ time = 40 msec. Design copied from Saturn occ on rev 128, planned with DeTour. 8*8 cubes; X_0 = 32, Z_0 = 48. VIMS_167RI_COMPLIT001_PIE ..... 2012-157 ..... 105 Mb This is the highest-resolution opportunity in the XXM to obtain VIMS spectral observations of the sunlit side of the rings at a low phase angle. At a range of 270-360 kkm, the VIMS resolution will be between 70 km and 90 km/pixel in hi-res mode, which is sufficient to resolve spectral variations between features such as the narrow plateaux in the outer C ring. VIMS will obtain a complete radial scan of the left ring ansa, using about 20 hi-res cubes, running parallel to the planet's shadow across the rings in order to minimize the effect of scattered light from Saturn. The secondary axis of POS_Z to NSP was chosen to orient the VIMS fast-scan (& hi-res) direction radially on the rings. Duration = 3:00. ------------------------------------------------------------------------- S74: revs 168-170 |-------------------------------------| | PDT designs delivered, ~15 Jan 2012 | | IOIs approved, 20 Apr 2012. | |-------------------------------------| VIMS_168RI_APOMOSAIC001 ..... 2012-171 ..... 154 Mb VIMS will acquire a 4*2 mosaic of the planet & darkside rings from a range of approx. 47 R_S, to look for azimuthal variations in the rings' brightness and spectrum, as well as any unexpected changes in Saturn's atmosphere. Integration times of 160 & 640 msec per pixel will be used. Part of a bimonthly monitoring campaign. Duration = 12:00 VIMS_168RF_FMOVIE002_ISS ..... 2012-179 ..... 36 Mb VIMS rides along on an ISS F ring movie, for 4:35, staring at one ansa and collecting a series of IR spectra as a function of corotating longitude. LoRes mode to avoid gaps in coverage. FOV includes Encke Gap. VIMS_168RI_DRCLOSE001_ISS ..... 2012-180 ..... 45 Mb VIMS rides along on a high-resolution ISS D ring obsv'n, for 5:21. 24*64 size cubes to avoid planet's shadow. VIMS_168SA_ALPCMAOCC001_UVIS ..... 2012-180 ..... 60 Mb As a rider on the UVIS ring occultation, UVIS_068ST_URALPCMA001, VIMS will observe the ingress occultation of the bright star Alpha CMa (= Sirius) by Saturn's equatorial limb, at latitude -2.6 deg. This observation is a close copy of the VIMS PIE on rev 169, and samples the same latitude on Saturn. It thus provides a valuable backup to the rev 169 occ, and also permits us to check the reproducibility of the results from that observation. The Saturn occultation occurs at 23:30, midway through the UVIS observation, and VIMS will first acquire the star after it emerges from behind the B ring at 23:05 to observe a C ring occultation. Reacquire star in D ring to observe Saturn occ without spectral summing. Tau_IR = 20 ms. VIMS_168RI_COMPLIT001 ..... 2012-181 ..... 60 Mb This is an excellent opportunity for VIMS to obtain high-resolution spectral observations of the sunlit side of the rings at a moderately low phase angle (65 deg). At a range of 340 kkm, the VIMS resolution will be 85 km/pixel in hi-res mode, which is sufficient to resolve spectral variations within features such as the narrow plateaux in the outer C ring. VIMS will obtain a complete radial scan of the left ring ansa, using 14 hi-res cubes, running roughly parallel to the planet's shadow across the rings in order to minimize the effect of scattered light from Saturn. Sec axis is +Z_to_NSP. Although this observation is an hour shorter, it will provide a valuable backup opportunity for the very similar VIMS PIE on rev 167. Tau_IR = 160 ms. Duration = 2:10. The design was over its allocation by 39 Mb, so we reduced the cube size to 32*64 & increased tau_IR. VIMS_169RI_HIPHASE001 ..... 2012-204 ..... 150 Mb This is a 4 hour observation of the unlit side of the rings at extremely high phase angles (150 - 175 deg), and unusually high resolution. At a range of 440 kkm, the VIMS resolution will be 110 km/pixel in hi-res mode, which is sufficient to resolve many of the narrow gaps in the Cassini Division, as well as isolate several narrow ringlets in the tenuous D ring. During the first hour, when the sun is eclipsed by Saturn and we can observe at phase angles exceeding the usual limit of 165 deg, ISS will target the A and C rings to look for impacts of interplanetary debris on the rings. In the last 3 hours, VIMS will target first the D ring and then the F ring, on the left ansa, at phase angles of 150 - 160 deg. B = 16 deg, range = 7.5 RS. Cube size 64*32. This observation is in a Custom Turn period, picking up at X_Band to Earth and handing off at ISS_NAC to Saturn. Tau_IR = 320 ms. Duration = 4:17. VIMS_169SA_ALPCMAOCC001_PIE ..... 2012-204 ..... 60 Mb VIMS will observe the ingress occultation of the bright star Alpha CMa (= Sirius) by Saturn's equatorial limb, at latitude -2.6 deg. This is one of a set of a dozen stellar occultations selected by the SWG to span the full range of latitudes on Saturn. By combining the temperature profiles extracted from the VIMS lightcurves at several wavelengths with near-simultaneous limb scans by CIRS, we hope to determine the ratio of helium to hydrogen in Saturn's atmosphere, a key -- and as yet unfulfilled -- goal of Cassini's atmospheric investigation. Prior to the occultation itself, which occurs at 22:05, CIRS will obtain limb integrations using their FP3 detector array at the occultation latitude as well as a location 5 deg to the north. At each latitude, 2 pointings are necessary to provide sufficient vertical coverage. After the two CIRS limb pointings, VIMS will observe AlpCMa as it is occulted by the C ring in Saturn's shadow. Finally, VIMS will reacquire the star after it emerges from behind the C ring and observe it for 30 min as it is occulted by Saturn's limb. Tau_IR = 20 ms for both obsv'ns. VIMS_170RF_FMOVIE001_ISS ..... 2012-222 ..... 132 Mb VIMS rides along on an ISS F ring movie, for 16:00, staring at one ansa and collecting a series of IR spectra as a function of corotating longitude. FOV covers entire A ring. VIMS_170RI_BETPEGOCC002 ..... 2012-224 ..... 90 Mb VIMS will observe the slow egress occultation of Beta Pegasi, as it emerges from behind Saturn and then makes a radial pass across the entire ring system. The star is in Saturn's shadow, which will largely eliminate background contamination of the light curve. This observation complements the ingress occultation of Beta Peg scheduled on rev 172. Opening angle = 31.7 deg. Duration = 6:25. Tau_IR = 40 ms. Initial star acquisition is in the inner C ring, and we may reacquire the star in the outer C ring for security. This design is 15 Mb over its allocation. VIMS_170RI_HIRESFRNG001_ISS ..... 2012-225 ..... 32 Mb VIMS rides along on a high-resolution ISS F ring obsv'n, for 2:00. Keep A ring edge in FOV for navigation. VIMS_170RF_FMOVIE003_ISS ..... 2012-226 ..... 90 Mb VIMS rides along on an ISS F ring movie, for 11:10, staring at one ansa and collecting a series of IR spectra as a function of corotating longitude. Note that phase angle gets down to 1 deg, but on the opposite ansa! ------------------------------------------------------------------------- S75: revs 171-173 |-------------------------------------| | Segment delivered, 2 Mar 2012 | | PDT designs due, ~3 Apr 2012 | | IOIs approved, 28 June 2012. | |-------------------------------------| VIMS_171SA_USUNOCC001_UVIS ..... 2012-246 ..... 65 Mb VIMS rides along on a UVIS Saturn solar egress occ, at latitude +37.4 deg.

VIMS_171RI_DRLPMOV001_ISS ..... 2012-249 ..... 50 Mb VIMS rides along on an ISS D ring movie, for 5:50, staring at one ansa and collecting a series of IR spectra as a function of corotating longitude. VIMS_172RI_APOMOSAIC001 ..... 2012-261 ..... 156 Mb VIMS will acquire a 4*3 mosaic of the planet & darkside rings from a range of approx. 40 R_S, to look for azimuthal variations in the rings' brightness and spectrum, as well as any unexpected changes in Saturn's atmosphere.

VIMS_172RI_BETPEGOCC001 ..... 2012-266 ..... 132 Mb VIMS will observe the slow ingress occultation of Beta Pegasi, as it makes a radial pass across the entire ring system & behind Saturn's bright limb. This observation complements the egress ring occultation of Beta Peg scheduled on rev 170. Opening angle = 31.7 deg. Duration = 6:05. Integ time = 40 msec. VIMS_172RI_SOLAROCCA ..... 2012-267 ..... 150 Mb VIMS observes a radial passage of the sun behind the rings, from the F ring to the inner edge of the C ring. Opening angle = 15.9 deg, range = 9.3 RS. Duration = 2:07. Data will be used to further constrain the size distribution of mm-sized particles in the main rings, by imaging the "aureole" of forward-scattered sunlight. Integ time = 40 msec; 8*8 cubes; X_0 = 28, Z_0 = 28. VIMS_172RI_HIPHASE_ISS ..... 2012-268 ..... 25 Mb VIMS rides along on an ISS hi-phase observation of the G ring and its embedded moonlet, Aegaeon. Data will be used to constrain the particle size distribution. VIMS_172RI_0PHASEB ..... 2012-269 ..... 171 Mb VIMS observes a radial passage of the anti-solar point across the left ansa of the rings, from the F ring to the middle D ring, to map out the rings' opposition effect between phase angles of 0 and 1.0 deg. Ring opening angle = 16 deg. Distance = 11 R_S. Duration = 3:58. Integ time = 60 msec, with ~5 min per cube. Acquire approx 24 cubes from 09:30 to 11:30, targeted at the anti-solar point (+Y to Sun), with integ time = 60 ms (IR) & 2560 ms (VIS). For the final 1.5 hrs we will obtain images of the left ansa of the rings at a phase angle which matches that of Earth-based observations, to provide cross-calibration between Cassini and terrestrial near-IR spectra. This will be done by executing three 4*1 radial mosaics from 75 kkm to 135 kkm, with 5 min dwell times. Data vol (~30 Mb) may limit these cubes to short strips. NEG_X to 132/+59. VIMS_173RI_SPOKEMOV003_ISS ..... 2012-286 ..... 317 Mb VIMS rides along on an ISS spoke movie, for 18:24, staring at the shadowed ansa and collecting a series of 32*64 cubes as a function of corotating longitude. The following 24 hrs is used to collect 80 & 500 msec cubes on the dark side of Saturn for cloud tracking & an auroral survey. VIMS_173RI_DRNGMOV001_ISS ..... 2012-289 ..... 59 Mb VIMS rides along on an ISS D ring movie, for 7:00, staring at one ansa and collecting a series of IR spectra as a function of corotating longitude. VIMS_173RF_FMOVIE001_ISS ..... 2012-289 ..... 133 Mb VIMS rides along on an ISS F ring movie, for 16:10, covering 30 deg of inertial longitude on each ansa and collecting a series of IR spectra as a function of corotating longitude. VIMS_173SU_SOLARPORT ..... 2012-290 ..... 85 Mb VIMS obtains spectra of the sun thru its solar port, for calibration purposes. In this observation we will map out the PSF of the Solar Port, in the X and Z directions by scanning across the Sun at 5 urad/sec over a range of 4 mrad = 800 sec. Integ. time = 40 msec, 12*12 cubes = 10 sec/cube. 110 cubes & 12 Mb per scan. Stare at sun for remainder of time; duration = 5:40. Occurs during a very high-phase period. VIMS_173RI_HIPHWAC_ISS ..... 2012-291 ..... 32 Mb VIMS rides along on an ISS hi-phase WAC mosaic (12*4 frames) of the E ring. A combination of 1*64 and 64*3 cubes chosen to fit ISS dwell times, oriented ~radially. This will not provide VIMS with a complete map of the E ring, given the larger FOV of the WAC and limited integration time available. VIMS_173RI_DRCLOSE001_ISS ..... 2012-291 ..... 34 Mb VIMS rides along on a high-resolution ISS D ring obsv'n, for 4:10.

First obtain ~11 hrs of calibration data on the sun, and then observe transit from 12:25 to 22:20. Total duration = 21:45. IR_only; 6*6 cubes; tau_IR = 70 msec. Target VIMS_SOLAR_PORT to Sun and use offset X_0 = 26, Z_0 = 28. 20,180 cubes. [NOTE: we assumed a compression ratio of 3.5:1 here, but the actual ratio achieved was only 1.94, with Time_insertion ON. So 40% of the data was lost to data policing.
