Summary of Impact Experiments

Legend
  • X indicates that a measurement was not possible due to poor data quality or was not made for highly oblique
    impacts.
  • NA indicates not applicable for impacts with no measureable ejecta.
  • (M) indicates the speed of the ejecta rim in the mirror. (C) indicates the
    speed of the ejecta “cusp”.  Target codes: S = quartz sand, L = JSC-1 lunar regolith simulant, M = JSC-Mars-1
    martian regolith simulant, M500 = JSC-Mars-1, sieved to remove all particles
    smaller than 500 mm.

See text for details. Ejecta mass codes (M1, M2, M3) are defined in the text.
