DAEDALIA PLANUM IS FORMED IN PART BY SOME OF THE YOUNGEST AND MOST PROFUSE VOLCANIC ACTIVITY ON MARS ORIGINATING FROM THE SOUTHWEST FLANK OF ARSIA MONS. THE LARGE LAVA FLOWS IN THIS AREA HAVE NOT BEEN THE FOCUS OF THERMAL INFRARED (IR) STUDIES IN THE PAST BECAUSE OF THE MODERATELY-HIGH VISIBLE (VIS) ALBEDO THOUGHT TO BE CAUSED BY AN OPTICALLY-THICK MANTLING OF DUST. MORE RECENT STUDIES SUGGEST THAT THE MANTLING MAY NOT BE SPATIALLY UNIFORM IN THIS AREA BUT RATHER THAT THESE SURFACES CONTAIN LARGER LAVA OUTCROPS RISING ABOVE LOWLYING REGIONS FILLED WITH DUST/SAND. THEREFORE MORE DETAILED IR AND VIS SPECTRAL ANALYSIS IS WARRANTED IN ORDER TO POSSIBLY EXTRAPOLATE THE SPECTRAL SIGNATURE OF THOSE OUTCROPS AND DECIPHER THE VOLCANIC AND EOLIAN HISTORY OF DAEDALIA. THE PROPOSED STUDY HERE WILL FOCUS ON THE FLOWS WITH THE YOUNGEST RELATIVE AGES AND SPECIFICALLY ON SPECTRAL CHANGES BETWEEN DIFFERENT FLOWS AND WITH DISTANCE ALONG INDIVIDUAL FLOWS. THERE ARE THREE GENERAL OBJECTIVES: (1) EXTRACT SPECIFIC THERMOPHYSICAL INFORMATION FROM LAVA FLOW SURFACES SUCH AS THERMAL INERTIA (TI) TO QUANTIFY THE PERCENT BEDROCK ON A FLOW SURFACE; (2) MODEL THE IR SPECTRAL INFORMATION OF THOSE BEDROCK OUTCROPS TO DETERMINE COMPOSITIONAL CONSTRAINS; AND (3) EXAMINE THE VARIATIONS IN FLOW SURFACE CHARACTERISTICS (E.G. ABUNDANCE OF THE LAVA FLOW OUTCROPS COMPOSITIONAL CHANGES ETC.) TO CONSTRAIN THE VOLCANIC HISTORY AND THE SUBSEQUENT DEGRADATION/MANTLING. APPLICATION OF A MULTI-INSTRUMENT MULTI-SPECTRAL APPROACH COMBINED WITH THERMOPHYSICAL AND MORPHOLOGICAL MODELING WILL PROVIDE THE NECESSARY DATA. THE FIRST TASK WILL USE HIGH SPATIAL RESOLUTION VIS DATA (E.G. CTX AND HIRISE) WITH MODERATE TO HIGH SPECTRAL RESOLUTION IR DATA (E.G. THEMIS) TO QUANTIFY THE THERMOPHYSICAL VARIATIONS BETWEEN AND WITHIN INDIVIDUAL FLOWS AND IDENTIFY SURFACES WITH SIGNIFICANT UNMANTLED LAVA OUTCROPS. THIS METHOD HAS BEEN TESTED ON A PORTION OF THE STUDY AREA AND PROVIDES VALIDITY FOR THIS APPROACH. THE SECOND TASK WILL APPLY TWO-COMPONENT THERMOPHYSICAL MODELING OF THERMAL INERTIA VALUES TO SURFACES IDENTIFIED AS POSSESSING THESE MIXTURES TO DETERMINE THE PERCENT ABUNDANCES OF EACH COMPONENT. SIGNIFICANT PERCENTAGES OF EXPOSED OUTCROPS WILL BE TARGETED FOR SPECTRAL/COMPOSITIONAL ANALYSIS IN ORDER TO CONSTRAIN THE ERUPTION CHARACTERISTICS AND PROCESSES OVER TIME INCLUDING ERUPTION RATE VISCOSITY AND COMPOSITION. FINAL RESULTS WILL PROVIDE IMPORTANT DETAILS ON THE EMPLACEMENT HISTORY OF A REGION WITH SOME OF THE YOUNGEST VOLCANIC ACTIVITY ON MARS AND HOW LATER EOLIAN PROCESSES AFFECTED THE SURFACE CHARACTERISTICS. TAKEN IN TOTAL THIS PROPOSAL DIRECTLY ADDRESSES THE FOLLOWING RESEARCH THEMES SOLICITED BY THE NESSF PROGRAM: 1) EXPLORE AND OBSERVE THE OBJECTS IN THE SOLAR SYSTEM TO UNDERSTAND HOW THEY FORMED AND EVOLVED; AND 2) ADVANCE THE UNDERSTANDING OF HOW THE CHEMICAL AND PHYSICAL PROCESSES IN THE SOLAR SYSTEM OPERATE INTERACT AND EVOLVE. FURTHERMORE THIS RESEARCH ADVANCES THE GOALS OUTLINED IN THE 2014 NASA SCIENCE PLAN FOR THE MARS EXPLORATION PROGRAM TO CHARACTERIZE AND UNDERSTAND MARS AS A SYSTEM INCLUDING ITS CURRENT ENVIRONMENT CLIMATE AND GEOLOGICAL HISTORY AND BIOLOGICAL POTENTIAL.
