The Population of Young Craters on the Moon: New Catalog and Spatial and Temporal Analysis
Autor: Rebecca R. Ghent, Emily S. Costello, A. H. Parker
Publikováno v: The Planetary Science Journal, Vol 5, Iss 4, p 89 (2024)
We present a new catalog of the Moon’s rayed and rocky craters from 5 to 130 km in diameter. Using data from the Lunar Reconnaissance Orbiter and the JAXA Kaguya/Selene missions, we identify 571 unique craters with albedo, maturity, and/or thermoph

The Variability of Lunar Mare Basalt Properties from Surface Rock Abundance
Autor: Catherine M. Elder, Rebecca R. Ghent, James Haber, Paul O. Hayne, Gareth Morgan, Mark S. Robinson, Matt Siegler, Jean-Pierre Williams
Publikováno v: The Planetary Science Journal, Vol 4, Iss 12, p 244 (2023)
We use the Lunar Reconnaissance Orbiter Diviner Lunar Radiometer Experiment surface rock abundance data set to investigate how rock content changes with surface age in the maria. We find that surface rock abundance decreases with unit age as expected

Impact gardening on Europa and repercussions for possible biosignatures
Autor: Cynthia B. Phillips, E. S. Costello, Paul G. Lucey, Rebecca R. Ghent
Publikováno v: Nature Astronomy. 5:951-956
Owing to its internal ocean, Jupiter’s moon Europa can potentially host extant life. However, because Europa’s orbit is within Jupiter’s magnetosphere, chemical biosignatures that are exposed to space may be destroyed by high-energy electron ra

The Effects of Terrain Properties Upon the Small Crater Population Distribution at Giordano Bruno: Implications for Lunar Chronology
Autor: J.‐P. Williams, A. V. Pathare, E. S. Costello, C. L. Gallinger, P. O. Hayne, R. R. Ghent, D. A. Paige, M. A. Siegler, P. S. Russell, C. M. Elder
Publikováno v: Journal of geophysical research. Planets. 127(5)
The distribution of impact craters on the ejecta of Giordano Bruno, a recent (10 Ma) 22-km diameter crater within the lunar highlands, exhibits substantial variations. We surveyed craters

Publikováno v: Černok, A, White, L, Anand, M, Tait, K, Darling, J, Whitehouse, M J, Lemelin, M, Reddy, S, Fougerouse, D, Rickard, W, Saxey, D & Ghent, R 2021, ' Lunar samples record an impact 4.2 billion years ago that may have formed the Serenitatis Basin ', Communications Earth and Environment, vol. 2, 120 . https://doi.org/10.1038/s43247-021-00181-z
Impact cratering on the Moon and the associated size-frequency distribution of impact craters has been used to determine the ages of the lunar and planetary surfaces across the Solar System1,2. Radiometric age-dating of lunar samples plays a critical
