  • The Distribution and Accessibility of Geologic Targets near the Lunar South Pole and Candidate Artemis Landing Sites 
    Kring, David A. (David Allen); Barrett, Natasha; Bickel, Valentin Tertius; Satyakumar, Animireddi V.; Halim, Samuel; Gawronska, Aleksandra; Harish; Shah, Jahnavi; Boazman, Sarah (The Planetary Science Journal, 2022-12-22)
    Transformative lunar science will be driven by the accessibility, recovery, and return to Earth of geological specimens. Isolated boulders, rock exposures, and rocky craters at the lunar south pole all provide opportunities ...
  • Evidence for early volcanism in Mare Smythii 
    Conca, James; Hubbard, Norman (Pergamon Press, 1979)
    The major geologic units in and around the Smythii basin are reflected in the Al2O3 and MgO values obtained using improved orbital X-ray fluorescence data from Apollo 15. One of these units is a high albedo plains-forming ...
  • Lunar crater chains of non-impact origin 
    Eppler, Dean B.; Heiken, Grant (Pergamon Press, 1975)
    Lunar crater chains consisting of three or more aligned craters with similar states of degradation were identified from Apollo 15, 16, and 17 orbital photographs and selected for detailed study. Secondary crater chains ...
  • Lunar impact basins revealed by Gravity Recovery and Interior Laboratory measurements 
    Neumann, Gregory A.; Zuber, Maria T.; Wieczorek, Mark A.; Head, James W.; Baker, David M. H.; Solomon, Sean C.; Smith, David E.; Lemoine, Frank G.; Mazarico, Erwan; Sabaka, Terence J.; Goossens, Sander J.; Melosh, H. J.; Phillips, R. J. (Roger J.), 1940-2020; Asmar, Sami W.; Konopliv, Alexander S.; Williams, James G.; Sori, Michael M.; Soderblom, Jason M.; Miljković, Katarina; Andrews-Hanna, Jeffrey C.; Nimmo, Francis; Kiefer, Walter S.; https://orcid.org/0000-0001-6741-5460 (American Association for the Advancement of Science, 2015-10-30)
    Observations from the Gravity Recovery and Interior Laboratory (GRAIL) mission indicate a marked change in the gravitational signature of lunar impact structures at the morphological transition, with increasing diameter, ...
  • Numerical modeling of the formation of Shackleton crater at the lunar south pole 
    Halim, Samuel; Barrett, Natasha; Boazman, Sarah; Gawronska, Aleksandra; Gilmour, Cosette; Harish; McCanaan, Kathryn; Satyakumar, Animireddi V.; Shah, Jahnavi; Kring, David A. (David Allen); https://orcid.org/0000-0003-3150-6787; https://orcid.org/0000-0002-3440-6282; https://orcid.org/0000-0002-4964-1138; https://orcid.org/0000-0002-4978-530X (Elsevier, 2021-01-15)
    The lunar south pole, on the rim of Shackleton crater, is the target for the next human landing on the Moon. We use numerical modeling to investigate the formation of that crater and the distribution of ejecta around the ...
  • Orbital infrared observations of lunar craters and possible implications for impact ejecta emplacement 
    Schultz, Peter H., 1944-; Mendell, W. W. (Wendell W.), 1941- (Pergamon Press, 1978)
    The Apollo 17 Scanning Infrared Radiometer experiment showed that the ejecta deposits of large lunar craters (D greater than 3 km) typically exhibit uniform nighttime temperatures comparable to or less than those of the ...
  • The origin of lunar mascons: Analysis of the Bouguer gravity associated with Grimaldi 
    Phillips, R. J. (Roger J.), 1940-2020; Dvorak, John (1981)
    Grimaldi is a relatively small multi-ringed basin located on the western limb of the moon. Spacecraft free-air gravity data reveal a mascon associated with the inner ring of this structure, and the topographic correction ...
  • A South Pole–Aitken impact origin of the lunar compositional asymmetry 
    Jones, Matt J.; Evans, Alexander J.; Johnson, Brandon C.; Weller, Matthew B.; Andrews-Hanna, Jeffrey C.; Tikoo, Sonia M.; Keane, James Tuttle (American Association for the Advancement of Science, 2022-04-08)
    The formation of the largest and most ancient lunar impact basin, South Pole–Aitken (SPA), was a defining event in the Moon's evolution. Using numerical simulations, we show that widespread mantle heating from the SPA ...
