  • Stepinski, Tomasz F.; Vilalta, Ricardo (Intech, 2010-02-01)
    Machine learning can play a vital role in automating the process of geomorphic mapping. A learning system can be employed to either fully automate the process of discovering meaningful landform classes using clustering ...
  • McCubbin, Francis M.; Treiman, Allan H.; https://orcid.org/0000-0002-8073-2839 (Mineralogical Society of America, 2015-08-01)
    Many studies exist on magmatic volatiles (H, C, N, F, S, Cl) in and on the Moon, within the last several years, that have cast into question the post-Apollo view of lunar formation, the distribution and sources of volatiles ...
  • Wagman, L. P. (Louis P.) (Bendix Aerospace Systems Division, 1970)
    The purpose of this ATM is to update the ALSEP Magnetic Cleanliness Guidelines as delineated in ATM-294, dated 1 June 1966. This update is necessitated by the new complement of experiments to be flown on the ALSEP Flight ...
  • Dunlop, D. J.; Gose, W. A.; Pearce, G. W.; Strangway, D. W. (Pergamon Press, 1973)
    Based on a detailed study of time-dependent or viscous remanence (VRM), thermoremanence (TRM) and magnetic granulometry of soil breccia 14313, single-domain particles of iron 100-200 Å in size are proposed as the major ...
  • Gose, W. A.; Pearce, G. W.; Strangway, D. W.; Larson, E. E. (Pergamon Press, 1972)
    The magnetic properties of Apollo 14 breccias can be explained in terms of the grain size distribution of the interstitial iron which is directly related to the metamorphic grade of the sample.
  • Pearce, G. W.; Strangway, D. W.; Gose, W. A. (Pergamon Press, 1974)
    The magnetic properties of a number of Apollo 17 samples have been measured and confirm that regoliths of mare sites (Apollo 11, 12, 15 valley, and 17 valley) differ markedly from those of highland sites (Apollo 14, 16, ...
  • Pearce, G. W.; Gose, W. A.; Strangway, D. W. (Pergamon Press, 1973)
    The magnetic properties of lunar samples are almost exclusively due to rather pure metallic iron. The mare basalt contains about 0.06 wt.% Fe, the soils 0.5--0.6 wt.%, and the breccias 0.3-1.0 wt.%. Most of the additional ...
  • Parker, Everette. (Bendix Systems Division, 1966)
    This report describes the latest estimate from Ames Research Center (ARC) of the magnetometer power profile.
  • Honeycutt, R.; Coleman, C. W. (Bendix Systems Division, 1966)
    This ATM is a statement of the magnetometer processing currently included in the DPS 2000 computer programs being written for the ALSEP System Test Set.
  • Blanchard, Douglas P.; Brannon, Joyce C.; Aaboe, Erik; Budahn, James R. (Pergamon Press, 1978)
    We have analyzed 6 Luna 24 soils for major and trace elements by atomic absorption spectrophotometry (AAS) and instrumental neutron activation analysis (INAA). We have also analyzed size fractions (90-150 μm and <20 μm) ...
  • Reid, Arch M.; Warner, Jeffrey L.; Ridley, W. I.; Johnston, Dennis A.; Harmon, Russell S.; Jakeš, Petr; Brown, Roy W. (Pergamon Press, 1972)
    Data on the major element composition of glasses in Apollo 11, 12, and 14 and Luna 16 soils have been classified into groupings of preferred compositions by cluster analysis techniques. These preferred compositions are ...
  • Myers, Dale D. (Dale Dehaven), 1922- (Manned Space Flight Experiments Board, 1972)
  • Banerdt, W. Bruce (William Bruce); https://orcid.org/0000-0003-3125-1542; Beaty, D. W. (David W.); Papike, J. J. (James Joseph), 1937-; Shearer, Charles K. (Lunar and Planetary Institute, 2012)
    The goal of this workshop is to summarize what we know as well as what we need to know about the origin, evolution, and structure of the martian mantle (magma ocean vs. serial magmatism models, etc.)
  • Niihara, Takafumi; https://orcid.org/0000-0001-9535-6728; Joy, Katherine H.; https://orcid.org/0000-0003-4992-8750; Kring, David A. (David Allen) (Lunar and Planetary Institute, 2013-02-28)
    Joy et al. (2012) utilized a new element mapping routine that was developed to locate specific phases in complex crystalline or brecciated rocks. Several simple computer routines (macros) were developed to manage the data ...
  • Bedford, A.; Douthat, D. Z.; Gilson, R. (Bendix Aerospace Systems Division, 1967)
    This is the fifth monthly progress report on the ALSEP Engineering Model Systems Tests which covers the efforts during the time period 1 March through 31 March.
  • Ryder, Graham (Lunar and Planetary Institute, 1989)
    Olivine-nonnative mare basalts are present on the Apennine Front as crystalline particles and shocked or shock-melted fragments. Picritic basalts, which may be related to the olivine-nonnative basalts by olivine accumulation, ...
  • Solomon, Sean C. (Pergamon Press, 1975)
    In this paper, simple hydrostatic concepts are extended to synthesize results from experimental petrology, lunar chronology, thermal history models, seismology, and gravity. Explanations of several heretofore unrelated ...
  • Briggs, Geoffrey, 1941-; Gulick, Virginia C. (Lunar and Planetary Institute, 1997)
    The purpose of this workshop was to reexamine the science issues that will determine how an optimum sample return mission would be carried out in 2005 given the new context that has emerged for Mars exploration since the ...
  • Duke, Michael B.; Budden, Nancy Ann (Lyndon B. Johnson Space Center, 1993-11)
    Provides an overview of the status of the Mars Exploration Study, material presented, and discussions of open items being addressed by the study team. Assembled three teams of experts to discuss cost, dual-use technology, ...
