  • Automatic Characterization of Boulders on Planetary Surfaces From High-Resolution Satellite Images 
    Prieur, Nils Charles; Amaro, Brian; Gonzalez, Emiliano; Kerner, Hannah; Medvedev, Sergei; Rubanenko, Lior; Werner, Stephanie C.; Xiao, Zhiyong; Zastrozhnov, Dmitry; Lapôtre, Mathieu G. A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract Boulders form from a variety of geological processes, which their size, shape, and orientation may help us better understand. Furthermore, they represent potential hazards to spacecraft landing that need to be ...
  • The effect of target properties on transient crater scaling for simple craters 
    Prieur, Nils Charles; Rolf, Tobias; Luther, Robert; Wunnemann, Kai; Xiao, Zhiyong; Werner, Stephanie C. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The effects of the coefficient of friction and porosity on impact cratering are not sufficiently considered in scaling laws that predict the crater size from a known impactor size, velocity, and mass. We carried out a ...
  • Fragments Delivered by Secondary Craters at the Chang'E-4 Landing Site 
    Ding, Chunyu; Xiao, Zhiyong; Wu, Bo; Li, Yuan; Prieur, Nils Charles; Cai, Yuzhen; Su, Yan; Cui, Jun (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    The Chang'E‐4 landing site is depleted with boulders seen from both orbit and surface. However, the Yutu‐2 rover came across thousands of concreted fragments in and around an abnormally fresh crater that has more elevated ...
  • The self-secondary crater population of the Hokusai crater on Mercury 
    Xiao, Zhiyong; Prieur, Nils Charles; Werner, Stephanie C. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Whether or not self‐secondaries dominate small crater populations on continuous ejecta deposits and floors of fresh impact craters has long been a controversy. This issue potentially affects the age determination technique ...
