  • Lindsay, John F. (John Francis), 1941-2008 (Pergamon Press, 1974)
    Four dimensional cluster analysis of the grain size parameters (mean, standard deviation, skewness, and kurtosis) of 125 lunar soils from the Apollo 15, 16, and 17 sites has provided a basis for the construction of a general ...
  • Taylor, Stuart Ross, 1925-; Jakeš, Petr (Pergamon Press, 1974)
    In this paper we consider the evidence for and the implications of homogeneous accretion of the moon. Inter-element ratios are used to calculate the composition of the highland crust.
  • Bedford, C. C.; https://orcid.org/0000-0002-0783-1064; Schwenzer, S. P.; Bridges, John C.; Banham, S.; Wiens, Roger C.; Rampe, E. B.; Frydenvang, Jens; Gasda, Patrick J. (Elsevier, 2020-05-01)
    The Mars Science Laboratory Curiosity rover has encountered both ancient lithified and modern active aeolian dune deposits within Gale crater, providing an opportunity to study how aeolian processes have changed during ...
  • Bedford, Candice; https://orcid.org/0000-0002-0783-1064; Schwenzer, Susanne Petra; Bridges, John C.; Banham, Steven; Wiens, Roger C.; Gasnault, Olivier M.; Rampe, Elizabeth; Frydenvang, Jens; Gasda, Patrick J. (Elsevier, 2020-05)
    A ChemCam geochemical study of the ancient aeolian Stimson formation in Gale crater. The geochemical effect of mineral sorting in the ancient dunes has been preserved. The Stimson dunes were transported SW-NE, opposite to ...
  • Taylor, Stuart Ross, 1925-; Jakeš, Petr (National Aeronautics and Space Administration, 1977)
    The volatile elements (e.g., Rb, Pb, Tl, Bi, Cs) seem to have been depleted at the time of lunar hide accretion. Accordingly, it may be assumed that the moon initially accreted from refractory material. The good correlation ...
  • Gawronska, Aleksandra; Barrett, Natasha; Boazman, Sarah; Gilmour, Cosette; Halim, Samuel; Harish; McCanaan, Kathryn; Satyakumar , Animireddi V.; Shah, Jahnavi; Meyer, Heather; Kring, David A. (David Allen); https://orcid.org/0000-0002-6888-9868; McCanaan, Kathryn; Kring, David A. (David Allen) (Elsevier, 2020-05-25)
    The Artemis human landing system concept of operations is initially limited to two astronauts who land “on the lunar south pole” and will not exceed a surface stay of 6.5 days near the south pole (NASA, 2019a). Potentially, ...
  • Moore, J. (Jeff); Spencer, John R. (John Robert), 1957-; McKinnon, William B.; Howard, Alan D.; White, Oliver L.; Umurhan, Orkan M., 1969-; Schenk, Paul M.; Beyer, Ross A.; Singer, Kelsi N.; Stern, Alan, 1957-; Weaver, Harold A., 1953-; Young, Leslie A.; Smith, K. Ennico; Olkin, Cathy B.; New Horizons Geology and Geophysics Imaging Team (ISPRS, 2016)
    Pluto and Charon exhibit strikingly different surface appearances, despite their similar densities and presumed bulk compositions. Systematic mapping has revealed that much of Pluto’s surface can be attributed to ...
  • Lofgren, Gary E.; Donaldson, Colin H.; Usselman, Thomas M. (Pergamon Press, 1975)
    The quartz-normative (QN) basalts collected at the Apollo 15 site have a unique and consistent bulk chemistry, but display a systematic variation in phenocryst morphology and matrix texture. Experimental crystallization ...
  • Ridley, W. I.; Reid, Arch M.; Warner, Jeffrey L.; Brown, Roy W.; Gooley, R.; Donaldson, Colin H. (Pergamon Press, 1973)
    Major element analyses have been made of 309 glasses in two Apollo 16 soils, 60501 and 61221. Averages of preferred glass compositions are used as a guide to the nature of the major rock types contributing to these soils.
  • Kring, David A. (David Allen); https://orcid.org/0000-0002-3440-6282; Durda, Dan, 1965- (Lunar and Planetary Institute, 2012)
    In 2007, the National Research Council published a report called The Scientific Context for Exploration of the Moon, which provided NASA the scientific guidance it needed for an enhanced exploration program that would ...
  • Stepinski, Tomasz F.; Valageas, P. (Ames Research Center, 1996)
    It is currently thought that planets around solar-type stars form by the accumulation of solid matter entrained in a gaseous, turbulent protoplanetary disk. We have developed a model designed to simulate the part of this ...
  • Fouch, Matthew; Dombard, Andrew; Johnson, Catherine (Catherine Louise) (Lunar and Planetary Institute, 2010)
    Of the worlds in the solar system, the Moon is uniquely accessible for ground-based geophysical studies, including, but not limited to, active and natural source seismology, heat flow, electromagnetic methods, and gravity. ...
  • Taylor, Patrick A.; Rivera-Valentín, Edgard G.; Bonsall, Amber (2020)
    Any breakdown of the planetary radar programs using single-dish radio telescopes would be detrimental to planetary defense and small-body science and exploration on the timescale of the decadal survey.

  • Méndez, Abel; Rivera-Valentín, Edgard G.; https://orcid.org/0000-0002-4042-003X; Schulze-Makuch, Dirk, 1964-; Filiberto, Justin; https://orcid.org/0000-0001-5058-1905; Lynch, Kennda; https://orcid.org/0000-0001-5229-5515 (2020-07-14)
    In this white paper, we suggest a mass-energy habitability model as an example of how to adapt and expand the models used by ecologists to the astrobiology field. We propose to implement these models into a NASA Habitability ...

    NASA’s search for habitable environments has focused on alteration mineralogy of the Martian crust and the formation of hydrous minerals, because they reveal information about the fluid and environmental conditions from ...

    Although supremely unhospitable to life today, Venus’s geodynamic similarities to Earth provide the ultimate control case for understanding rocky planet evolution and habitability. It very likely had past long-term surface ...
