    Dunn, Tasha L.; Cressey, Gordon; McSween, Harry Y.; McCoy, Timothy J. (2010)
    Abstract2013Powder X-ray diffraction (XRD) is used to quantify the modal abundances (in wt%) of 18 H, 17 L, and 13 LL unbrecciated ordinary chondrite falls, which represents the complete petrologic range of equilibrated ...

    Zipfel, Jutta; SchröDer, Christian; Jolliff, Bradley L.; Gellert, Ralf; Herkenhoff, Kenneth E.; Rieder, Rudolf; Anderson, Robert; Bell, James F., III; Brückner, Johannes; Crisp, Joy A.; Christensen, Philip R.; Clark, Benton C.; De Souza, Paulo A.,Jr.; Dreibus, Gerlind; D'Uston, Claude; Economou, Thanasis; Gorevan, Steven P.; Hahn, Brian C.; Klingelhöfer, Göstar; McCoy, Timothy J.; McSween, Harry Y.; Ming, Douglas W.; Morris, Richard V.; Rodionov, Daniel S.; Squyres, Steven W.; Wänke, Heinrich; Wright, Shawn P.; Wyatt, Michael B.; Yen, Albert S. (2011)
  • Color and Albedo Heterogeneity of Vesta from Dawn 
    Reddy, Vishnu; Nathues, Andreas; Le Corre, Lucille; Sierks, Holger; Li , Jian-Yang; Gaskell, Robert; McCoy, Timothy J.; Beck, Andrew W.; Schroeder, Stefan E.; Pieters, Carle M.; Becker, Kris J.; Buratti, Bonnie J.; Denevi, Brett; Blewett, David T.; Christensen, Ulrich; Gaffey, Michael J.; Gutierrez-Marques, Pablo; Hicks, Michael; Keller, Horst Uwe; Maue, Thorsten; Mottola, Stefano; McFadden, Lucy A.; McSween, Harry Y.; Mittlefehldt, David; O'Brien, David P.; Raymond, Carol; Russell, Christopher (2012)
    Multispectral images (0.44 to 0.98 mm) of asteroid (4) Vesta obtained by the Dawn Framing Cameras reveal global color variations that uncover and help understand the north-south hemispherical dichotomy. The signature of ...
  • A coordinated spectral, mineralogical, and compositional study of ordinary chondrites 
    Dunn, Tasha L.; McCoy, Timothy J.; Sunshine, J. M.; McSween, Harry Y. (2010)
    Mineral compositions and abundances derived from visible/near-infrared (VIS/NIR or VNIR) spectra are used to classify asteroids, identify meteorite parent bodies, and understand the structure of the asteroid belt. Using a ...
  • Elemental Mapping by Dawn Reveals Exogenic H in Vesta's Regolith 
    Prettyman, Thomas H.; Mittlefehldt, David W.; Yamashita, Naoyuki; Lawrence, David J.; Beck, Andrew W.; Feldman, William C.; McCoy, Timothy J.; McSween, Harry Y.; Toplis, Michael J.; Titus, Timothy N.; Tricarico, Pasquale; Reedy, Robert C.; Hendricks, John S.; Forni, Olivier; Le Corre, Lucille; Li, Jian-Yang; Mizzon, Hugau; Reddy, Vishnu; Raymond, Carol A.; Russell, Christopher T. (2012)
    Using Dawn's Gamma Ray and Neutron Detector, we tested models of Vesta's evolution based on studies of howardite, eucrite, and diogenite (HED) meteorites. Global Fe/O and Fe/Si ratios are consistent with HED ...
  • Field Reconnaissance Geologic Mapping of the Columbia Hills, Mars Based on MER Spirit and MRO HiRISE Observations 
    Crumpler, L. S.; Arvidson, R. E.; Squyres, Steven W.; McCoy, Timothy J.; Yingst, A.; Ruff, S.; Farrand, W.; McSween, Harry Y.; Powell, M.; Ming, D. W.; Morris, R. V.; Bell, J.

    McSween, Harry Y.; Ruff, S. W.; Morris, R. V.; Gellert, R.; Klingelhöfer, Göstar; Christensen, Philip R.; McCoy, Timothy J.; Ghosh, A.; Moersch, J. M.; Cohen, B. A.; Rogers, A. D.; Schroder, C.; Squyres, Steven W.; Crisp, J.; Yen, A. (2008)
  • The origin of Vesta's crust: Insights from spectroscopy of the Vestoids 
    Mayne, R. G.; Sunshine, J. M.; McSween, Harry Y.; Bus, S. J.; McCoy, Timothy J. (2011)
    High quality VNIR spectra of 15 Vestoids, small asteroids that are believed to originate from Vesta, were collected and compared to laboratory spectra and compositional data for selected HED meteorites. A combination of ...
  • Petrologic insights from the spectra of the unbrecciated eucrites: Implications for Vesta and basaltic asteroids 
    Mayne, R. G.; Sunshine, J. M.; McSween, Harry Y.; McCoy, Timothy J.; Corrigan, Catherine M.; Gale, A. (2010)
  • Petrology of the unbrecciated eucrites 
    Mayne, R. G.; McSween, Harry Y.; McCoy, Timothy J.; Gale, A. (2009)
    Twenty-nine unbrecciated eucrites have been thoroughly characterized in terms of the petrologic factors that affect their spectra, such as mineral chemistry, modal adundances, grain sizes, and textures. We have conducted ...
