We propose a three year line_4: program of Mars observations which will enable us to address line_5: the following objectives: multispectral mapping of line_6: geological surface units, quantitative study of seasonal and line_7: interannual variations in albedo features, the diurnal line_8: behavior of martian clouds, observation of a classic dust line_9: storm season, measurements of the atmospheric concentration line_10: of ozone and the derived water vapor abundance, and line_11: observations of seasonal polar cap changes for comparison line_12: with earlier data sets. Thirteen sequences of observations line_13: are proposed to map the martian globe and to provide line_14: repeated observations of the regions of greatest scientific line_15: interest; these use the PC to observe Mars in visible and line_16: near UV wavelengths and the FOS to map ozone absorption. line_17: The sequences are designed for particular martian seasonal line_18: dates relevant to the scientific objectives. ! ! end of abstract general_form_proposers: lname: LEE fname: STEVEN mi: W. inst: COLORADO, UNIVERSITY OF country: USA ! lname: CLANCY fname: R.

The period includes two oppositions line_4: when multi spectral imaging by PC will be used for unit mapping line_5: of portions of the planet's surface. Cloud monitoring sequences line_6: in Cycles 1 and 3 will image Mars in such a way as to provide line_7: information on the diurnal development of the interesting "W" line_8: cloud complex. Cycle 2 includes a large portion of the classic line_9: dust storm season on Mars; during this period, the regions on line_10: Mars in which global and local dust storms develop (Hellas and line_11: Solis Planum) will be imaged frequently to monitor dust activity. line_12: Whenever possible, sequences have been designed to monitor the line_13: same season in two consecutive years in order to quantify inter- line_14: annual variability. line_15: All sequences include PC imaging using standard blue (F413M) and line_16: red (F673N) filters which are similar to those used for most Viking line_17: and Planetary Patrol images; comparison of these two wavelengths line_18: separates surface and atmospheric effects. Ozone concentrations, line_19: which are related to water abundance, will be studied using line_20: both uv filters on PC and meridional scans using FOS. ! question: 4 section: 1 line_1: HST provides a spatial resolution on Mars which is comparable to line_2: that of Viking approach images near opposition and which is better line_3: at all times than that of the best pictures obtained from Earth. line_4: The portion of a martian year which can be observed by HST without line_5: violating the solar constraint is longer than that normally used line_6: by terrestrial astronomers, permitting much more complete monitor- line_7: ing of the martian seasonal cycle and more opportunity to observe line_8: interannual variability. Comparisons of HST observations near line_9: opposition with Viking images will be very useful in mapping geo- line_10: logical units and searching for interannual changes due to dust. ! question: 5 section: 1 line_1: Scientifically, the relatively large number of exposures is line_2: necessary to provide the desired coverage of all longitudes on line_3: Mars at various seasons. Therefore the overhead time is large. line_4: Because Mars is a bright target, even on a flux per pixel basis, line_5: signal to noise considerations are not the primary factor line_6: controlling exposure times on PC. Instead, exposure times are line_7: determined by the expected variations in flux between pixels due line_8: to albedo variations on Mars. The flux per pixel for an average line_9: region of Mars does not vary either with position (assuming a line_10: Lambertian surface) or time (neglecting the relatively small line_11: effects of Mars' eccentric orbit). ! question: 6 section: 1 line_1: The seasonal variations which we wish to observe require that line_2: our sequences of exposures be executed within roughly +/- two weeks line_3: of the optimum date. All of our groups of exposures are designed line_4: to observe particular regions of Mars and therefore require con- line_5: straints within the 24 hour period. We have relaxed these con- line_6: straints as much as possible to avoid conflicts (e.g. our central line_7: meridian constraint was selected so that the equivalent time was line_8: greater than the HST period). Our sequences were designed so that line_9: observations of a particular longitude region require less than line_10: one unocculted portion of an orbit. ! question: 7 section: 1 line_1: We plan to use software at STSCI to perform standard geometric line_2: and radiometric calibrations. Imaging data will be processed line_3: using the Planetary Imaging and Cartography System (PICS) to line_4: produce standard map projections from the data and to mosaic them line_5: when appropriate. The resulting products will be monochromatic line_6: global and/or hemispheric maps of Mars. Projections obtained with line_7: different filters will be registered and differencing techniques line_8: will be used to map seasonal and diurnal variations. line_9: FOS data and ozone data obtained from PC will be reduced into maps line_10: of ozone abundance and subsequently used to extract water abund- line_11: ance. ! question: 10 section: 1 line_1: Much of the hardware and software for image processing will line_2: be supplied by the various institutions. The P.I. will devote line_3: 10% of his academic year time to the project. The JPL personnel line_4: will supply their time. ! !end of general form text general_form_address: lname: JAMES fname: PHILIP mi: B. category: PI inst: TOLEDO, UNIVERSITY OF ! ! end of general_form_address records fixed_targets: targnum: 10 name_1: STAR-HD23169 descr_1: STAR; TYPE = G2 V pos_1: RA = 3H 43M 15.1S +/- .1S, pos_2: DEC = 25D 41' 34" +/- .5" equinox: J1990.5 rv_or_z: V=+13.3 comment_1: CALIBRATION TARGET FOR MARS comment_2: CYCLE 0 OBSERVATION comment_3: BETWEEN 1-JAN-91 AND 25-JAN-91 fluxnum_1: 1 fluxval_1: V = 8.75 +/- .1, TYPE = G2 V ! targnum: 11 name_1: MARS-J1 pos_1: RA = 3H 40M 10.1S +/- .1S, pos_2: DEC = 21D 57' 56.4" +/- .1" equinox: J2000 comment_1: CML OF MARS FROM EARTH BET 285 315 comment_2: CYCLE 0 OBSERVATION comment_3: BETWEEN 1-JAN-91 AND 25-JAN-91 fluxnum_1: 1 fluxval_1: SURF(V) = 4.0 +/- 0.1 fluxnum_2: 2 fluxval_2: SURF-LINE(2500) = 2 +/- 1 E-13 fluxnum_3: 3 fluxval_3: W-LINE(2500) = 200 +/- 50 ! targnum: 12 name_1: MARS-FOS1 pos_1: RA = 3H 40M 10.0S +/- .1S, pos_2: DEC = 21D 57' 57.9" +/- .1" equinox: J2000 comment_1: CYCLE 0 OBSERVATION comment_2: BETWEEN 1-JAN-91 AND 25-JAN-91 fluxnum_1: 1 fluxval_1: SURF(V) = 4.0 +/- 0.1 fluxnum_2: 2 fluxval_2: SURF-LINE(2500) = 2 +/- 1 E-13 fluxnum_3: 3 fluxval_3: W-LINE(2500) = 200 +/- 50 ! targnum: 13 name_1: MARS-F1 pos_1: RA = 4H 7M 29.3S +/- .1S, pos_2: DEC = 23D 17' 44.5" +/- .1" equinox: J2000 comment_1: CML OF MARS FROM EARTH BET 285 315 comment_2: CYCLE 0 OBSERVATION comment_3: BETWEEN 5-FEB-91 AND 28-FEB-91 fluxnum_1: 1 fluxval_1: SURF(V) = 4.0 +/- 0.1 fluxnum_2: 2 fluxval_2: SURF-LINE(2500) = 2 +/- 1 E-13 fluxnum_3: 3 fluxval_3: W-LINE(2500) = 200 +/- 50 ! targnum: 14 name_1: MARS-F2 pos_1: RA = 4H 7M 29.9S +/- .1S, pos_2: DEC = 23D 17' 45.9" +/- .1" equinox: J2000 comment_1: CML OF MARS FROM EARTH BET 285 315 comment_2: CYCLE 0 OBSERVATION comment_3: BETWEEN 5-FEB-91 AND 28-FEB-91 fluxnum_1: 1 fluxval_1: SURF(V) = 4.0 +/- 0.1 fluxnum_2: 2 fluxval_2: SURF-LINE(2500) = 2 +/- 1 E-13 fluxnum_3: 3 fluxval_3: W-LINE(2500) = 200 +/- 50 ! targnum: 15 name_1: MARS-FOS2 pos_1: RA = 4H 7M 34.7S +/- .1S, pos_2: DEC = 23D 17' 57.4" +/- .1" equinox: J2000 comment_1: CYCLE 0 OBSERVATION comment_2: BETWEEN 5-FEB-91 AND 28-FEB-91 fluxnum_1: 1 fluxval_1: SURF(V) = 4.0 +/- 0.1 fluxnum_2: 2 fluxval_2: SURF-LINE(2500) = 2 +/- 1 E-13 fluxnum_3: 3 fluxval_3: W-LINE(2500) = 200 +/- 50 ! targnum: 16 name_1: MARS-MA1 pos_1: RA = 5H 28M 58.1S +/- .1S, pos_2: DEC = 25D 16' 37.2" +/- .1" equinox: J2000 comment_1: CML OF MARS FROM EARTH BET 285 315 comment_2: CYCLE 0 OBSERVATION comment_3: BETWEEN 20-MAR-91 AND 15-APR-91 fluxnum_1: 1 fluxval_1: SURF(V) = 4.0 +/- 0.1 fluxnum_2: 2 fluxval_2: SURF-LINE(2500) = 2 +/- 1 E-13 fluxnum_3: 3 fluxval_3: W-LINE(2500) = 200 +/- 50 ! targnum: 17 name_1: MARS-M1 pos_1: RA = 7H 39M 51.8S +/- .1S, pos_2: DEC = 23D 4' 40.4" +/- .1" equinox: J2000 comment_1: CML OF MARS FROM EARTH BET 30 60 comment_2: CYCLE 0 OBSERVATION comment_3: BETWEEN 14-MAY-91 AND 5-JUN-91 fluxnum_1: 1 fluxval_1: SURF(V) = 4.0 +/- 0.1 fluxnum_2: 2 fluxval_2: SURF-LINE(2500) = 2 +/- 1 E-13 fluxnum_3: 3 fluxval_3: W-LINE(2500) = 200 +/- 50 ! targnum: 18 name_1: MARS-M2 pos_1: RA = 7H 40M 38.5S +/- .1S, pos_2: DEC = 23D 2' 41.2" +/- .1" equinox: J2000 comment_1: CML OF MARS FROM EARTH BET 150 180 comment_2: CYCLE 0 OBSERVATION comment_3: BETWEEN 14-MAY-91 AND 5-JUN-91 fluxnum_1: 1 fluxval_1: SURF(V) = 4.0 +/- 0.1 fluxnum_2: 2 fluxval_2: SURF-LINE(2500) = 2 +/- 1 E-13 fluxnum_3: 3 fluxval_3: W-LINE(2500) = 200 +/- 50 ! targnum: 19 name_1: MARS-M3 pos_1: RA = 7H 41M 29S +/- .1S, pos_2: DEC = 23D 0' 31.1" +/- .1" equinox: J2000 comment_1: CML OF MARS FROM EARTH BET 270 300 comment_2: CYCLE 0 OBSERVATION comment_3: BETWEEN 14-MAY-91 AND 5-JUN-91 fluxnum_1: 1 fluxval_1: SURF(V) = 4.0 +/- 0.1 fluxnum_2: 2 fluxval_2: SURF-LINE(2500) = 2 +/- 1 E-13 fluxnum_3: 3 fluxval_3: W-LINE(2500) = 200 +/- 50 ! targnum: 20 name_1: MARS-M4 pos_1: RA = 7H 41M 29S +/- .1S, pos_2: DEC = 23D 0' 31.1" +/- .1" equinox: J2000 comment_1: CML OF MARS FROM EARTH BET 270 300 comment_2: CYCLE 0 OBSERVATION comment_3: BETWEEN 14-MAY-91 AND 5-JUN-91 fluxnum_1: 1 fluxval_1: SURF(V) = 4.0 +/- 0.1 fluxnum_2: 2 fluxval_2: SURF-LINE(2500) = 2 +/- 1 E-13 fluxnum_3: 3 fluxval_3: W-LINE(2500) = 200 +/- 50 ! ! end of fixed targets !
