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.
