  • Méndez, Abel; Rivera-Valentín, Edgard G.;; Schulze-Makuch, Dirk, 1964-; Filiberto, Justin;; Lynch, Kennda; (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 ...
  • Costell, Lacey J.; Filiberto, Justin;; Crandall, Jake R.; Potter-McIntyre, Sally L.; Schwenzer, Susanne Petra; Miller, Michael A.; Hummer, Daniel R.; Olsson-Francis, Karen; Perl, Scott (Elsevier, 2020-03-02)
    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 ...

Darby (Melinda Darby); Di Achille, G.; Fassett, Caleb; Gilmore, Martha S.; Grimm, Robert E.; Helbert, Jorn; Hensley, Scott; Herrick, Robert R.; Iess, Luciano; Jozwiak, Lauren; Katiaria, Tiffany; Mastrogiuseppe, Marco; Mazarico, Erwan; Mueller, Nils; Nunes, Daniel; O'Rourke, Joseph; McGovern, Patrick J.

    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 ...
  • Jang-Condell, Hannah; Gelino, Dawn (Dawn M.);; (Lunar and Planetary Institute, 2017)
    The workshop aims to address these questions: What does it mean to be habitable? What conditions are needed for habitability and how do those conditions arise? What are the indicators of these conditions and their histories? ...
  • Onorato, P. I. K.; Uhlmann, D. R.; Simonds, Charles H. (Pergamon Press, 1976)
    Results of calculations for the cooling of an impact melt sheet are reported for the sheet sampled by the Apollo 17 Station 6 Boulder. The calculations were based on a two-stage cooling model involving a short initial phase ...
  • Duke, Michael B.; Budden, Nancy Ann (Lunar and Planetary Institute, 1998)
    In the 1997-1998 school year, HEDS-UP sponsored six universities to conduct design studies on Mars exploration, using the Reference Mission as a basis for their work. The 1998 Mars Exploration Forum presents the results ...
  • Watters, Thomas R.; McGovern, Patrick J. (Geophysicist); (Lunar and Planetary Institute, 2004)
    The purpose of this two-day workshop is to discuss our current understanding of the martian hemispheric dichotomy in light of new data returned by Mars Global Surveyor and Mars Odyssey and upcoming data from Mars Express.
  • Hörz, Friedrich, 1940-; See, T. H.; Murali, A. V.; Blanchard, Douglas P. (Lunar and Planetary Institute, 1989)
    We confirmed the initial observations of Spencer (1933a,b) that two distinct impact melts coexist at the 90-m-diameter Wabar crater, Saudi Arabia A dark or "black" melt contains on the order of 4% meteoritic contamination, ...
  • Semprich, Julia; Filiberto, Justin;; (The Meteoritical Society, 2020-06-22)
    Here, we calculate the mineralogy of the Martian lower crust and upper mantle as a function of pressure and temperature with depth using four bulk compositions (average crust, Gusev basalt, olivine-phyric shergottite, and ...
  • Shipp, Stephanie, 1964-; Shupla, Christine (Lunar and Planetary Institute, 2008)
    Content and resources related to the Moon's formation and evolution. Front: Grade 6-9 students. Back: Educators of grades 6-9.

Des; Downs, G.; Downs, R. T.; Morookian, J. M.; Thorpe, M. (2020-06-19)
    A layer of weathering‐resistant material is located within the walls of an erosional gully of the Pu'u Poliahu cinder cone in the summit region of Maunakea volcano (Hawai'i). The volcanic cone, initially composed of unaltered ...
  • Clanton, Uel S., 1931-; Zook, Herbert A.; Schultz, Richard A. (Pergamon Press, 1980)
    The three largest Skylab IV Command Module windows that were exposed for 84 days to space were optically scanned for impact features as small as 30 µm in diameter. Some 289 features were recorded from the 35x scan for later ...
  • Wood, Charles A.; Whitford-Stark, James L.; Head, James W. (Lunar Science Institute, 1977)
    The discussions and itinerary in this guidebook are designed to provide a view of the spectrum of possible Icelandic analogs to planetary volcanic features.
  • Greeley, Ronald; Fink, J.; Gault, Donald E.; Snyder, D. B.; Guest, John, 1938-2012; Schultz, Peter H., 1944- (Pergamon Press, 1980)
    Martian multilobed craters ("splosh" craters, rampart craters, etc.) may involve fluidization of ejecta as a result of entrained water, melted/vaporized ice, and /or aerodynamically decelerated ejecta. To determine the ...
  • French, Bevan M.; Herrick, Robert R.; Pierazzo, Elisabetta (Lunar and Planetary Institute, 2003)
    The purpose of this workshop is to discuss how physical observations of craters, both on the Earth and on other solid bodies of the solar system, can be combined with the results from modeling of impact cratering for a ...
