During HST Cycles 0 and 2 we established line_4: that HST is an ideal instrument for assembling this record; excluding line_5: only the period when elongation is less than 50 degrees, Hubble can line_6: make scientifically useful observations during the entire synodic line_7: cycle of Mars. We propose to study Mars during the period from Aug. line_8: '93 through Aug. '94, when the elongation is within prescribed limits. line_9: In order to address the scientific questions of seasonal variability line_10: we shall concentrate observations at the martian seasonal dates on line_11: which Mars was imaged during previous cycles. WFPC2 filters which line_12: are analogous to the set used with the WFPC1 program will be used to line_13: maximize continuity. These include 410M, which will be used to study line_14: atmospheric and polar phenomena; 673N, which will be used to study line_15: variations in surface albedo features; and 502N, which is often useful line_16: in distinguishing between atmospheric and surface processes. Obtaining line_17: ultraviolet pairs using 255W and 336W will have a high priority during line_18: Cycle 4; Cycle 0 observations using 230W and 336W provided excellent line_19: data constraining dust, condensate haze, and ozone in the martian line_20: atmosphere. ! ! end of abstract general_form_proposers: lname: JAMES fname: PHILIP inst: 3580 country: USA ! lname: CLANCY fname: TODD inst: 1766 country: USA ! lname: LEE fname: STEVEN inst: 1766 country: USA ! lname: MARTIN fname: LEONARD inst: 2540 country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The orbit of Mars is such that its elongation exceeds 50 degrees for line_2: about one half of its 26 month synodic cycle. The next period starts line_3: on August 5, 1994 and ends on August 25, 1995. If Cycle 4 starts line_4: in March 1994 and ends in May 1995, there will be nine months of the line_5: observable portion of the synodic cycle in Cycle 4 and four months in line_6: Cycle 5. (Any change in the schedule of cycles would change this line_7: breakdown.) The Cycle 4 observations can be broken down as follows: line_8: monitoring sequences which provide coverage of the Syrtis face of Mars line_9: at periodic intervals, favoring Mars dates corresponding to Cycle 0 line_10: and 2 coverage. These are designed to study seasonal variations and line_11: interannual variations on the planet which can be separated line_12: because of the date constraints; a global sequence which include line_13: three equally spaced central meridians at the '95 opposition, line_14: which is at the same Ls as Cycle 0 and Cycle 2 observations; one line_15: target is used to search for a possible dust ring around Mars. ! question: 4 section: 1 line_1: Images of Mars which have sufficient surface resolution to be useful line_2: scientifically can be acquired using ground based telescopes only line_3: for a few months around oppositions. HST can provide scientifically line_4: useful images of the planet at its minimum angular diameter ofabout 4 line_5: secs. (This has been established by our Cycle 0 observations at 4.8 line_6: secs)In principal HST could monitor seasonal phenomena on Mars for the line_7: entire synodic cycle,but the solar pointing constraint eliminates about line_8: 45% of that time from consideration. The 1995 opposition is not line_9: especially good, and the angular size of Mars will be large enough line_10: for only about two months of scientifically useful ground based line_11: observations. HST will be able to observe the planet profitably for line_12: thirteen months. line_13: HST provides the only opportunity to observe Mars at violet and UV line_14: wavelengths. These observations, which are most sensitive to dust and line_15: condensates, also determine the concentration of ozone in the martian line_16: atmosphere. ! question: 5 section: 1 line_1: These observations are all time critical because they are to occur at line_2: specific dates on Mars in order to maximize the size of the planet or line_3: repeat coverage from a prior year. In addition, the observations line_4: should be targeted as closely as possible to specific central meridians line_5: on Mars in order to observed particular surface features or particular line_6: sites of atmospheric activity. Since the period of Mars is close line_7: to 24 hours, only one orbit per day will generally be suitable. The line_8: first target is especially time sensitive since it is constrained by line_9: the single ring plane crossing of earth during the observation period. ! ! question: 8 section: 1 line_1: John Clarke and David Crisp have submitted a proposal which emphasizes line_2: the use of the new linear ramp filter set to constrain the surface line_3: mineralogy as well as to investigate dust abundance and clouds. They line_4: also use far UV filters to study the extended O and H atmosphere. line_5: Temporally, these observations will be scheduled during the month line_6: preceding opposition. Their program largely complements ours, and line_7: there are only small overlaps. ! question: 9 section: 1 line_1: The programs mentioned above have established the value of HST line_2: monitoring the martian surface and atmosphere throughout the entire line_3: synodic cycle of the planet. The deconvolved images have provided line_4: sufficient resolution to successfully document atmospheric and surface line_5: changes on Mars. Examination of images has shown the appearance line_6: of albedo features in the Hellas region which have not been previously line_7: seen in earth based images. Compared to the dusty Viking years, the line_8: albedo patterns in the Syrtis region are very stable, showing little line_9: seasonal variation during the time they were monitored. A number of line_10: interesting cloud features in the polar regions have been seen in the line_11: images;images obtained during cycle 0 show detailed structure in the line_12: polar hood which suggests weather systems such as those observed by line_13: Mariner 9. Several discrete clouds were observed in martian line_14: midlatitudes; some can be identified with the famous "W" clouds line_15: of Slipher, but the pattern of clouds in the Tharsis - Valles line_16: Marineris region is not the same as observed in prior years. line_17: Opacities of these clouds and of the polar hood in the north were line_18: consistent with previous observations. ! question: 9 section: 2 line_1: We used radiative transfer codes to deduce the optical thickness line_2: of clouds, the amount of background dust opacity, and the concentration line_3: of ozone using the ultraviolet and violet images. The program has line_4: established the value of ultra violet imaging of Mars for studying O3 line_5: and dust concentrations in the atmosphere as well as for studying the line_6: behavior of surface reflectances at short wavelengths. The Viking line_7: observations in the 1970's revealed a very dusty martian atmosphere, line_8: and this image of Mars has persisted. However, the analysis of HST line_9: violet and ultraviolet images shows that the atmosphere of Mars was line_10: remarkably clear of dust. line_11: The FOS data analysis is also progressing well and has revealed that line_12: the signal to noise for the spectra are what we had expected. The FOS line_13: spectra have been ratioed to a solar spectrum to derive the UV line_14: spectrum of Mars for the various spectral scans across the planet. line_15: Hartley Band ozone absorption is strikingly displayed in the polar line_16: regions. The spectra have been analyzed using a radiative transfer line_17: model of the martian atmosphere which includes the small UV surface line_18: reflectance, Rayleigh scattering, condensate clouds, dust, and ozone line_19: absorption. The results on the polar cloud opacities and ozone line_20: concentrations are consistent with WFPC results referred to above and line_21: provide an upper limit for low latitude ozone concentrations. A line_22: publication on these results is currently in preparation. ! question: 10 section: 1 line_1: The institutions involved are providing funding in terms of data line_2: analysis facilities. Released time for the PI is included. ! !end of general form text general_form_address: lname: JAMES fname: PHILIP category: PI inst: 3580 addr_1: DEPARTMENT OF PHYSICS & ASTRONOMY city: TOLEDO state: OH zip: 43606 country: USA phone: 419-537-4906 telex: PBJ@UTPHYA.PHYA.UTOLEDO ! ! end of general_form_address records !
