  1. Geologic Mapping of Venus and Mars Leslie F. Bleamaster III San Antonio, TX

  2. Helen Planitiaand Isabella Quadrangle, Venus (PG&G)L. Bleamaster, D. Crown, E. Stofan, I. Lopez eastern hemisphere Overarching theme: Constrain the geologic/ thermal history of a particularly “young” region of Venus, and place it into global context. Helen Planitia, 1/8 of the planet Specific Studies: Helen- Map the distribution of medium to large sized volcano-tectonic centers Everywhere- Investigate relationship between craters with outflows and volcanic centers Isabella Crater inverted SAR Isabella Quadrangle (V50) synthetic aperture radar (SAR) Isabella- Understand the relationship between contractional deformation and small-scale volcanism

  3. Mawrth Vallisand Nili Fossae Mars (PG&G)L. Bleamaster, D. Crown, J. Mustard Note: both are MSL candidate landing sites!!! Science tasks: geologic mapping, geomorphic analyses, and chronologic studies characterization of the role and extent of volatile-driven, aeolian, volcanic, and tectonic modification and degradation processes on Mawrth Vallis, Nili Fossae, and Arabia Terra evaluation of the distribution, stratigraphic position, and lateral continuity of compositionally distinct outcrops as seen in spectral datasets (specifically phyllosilicates)
