We present our experimental data for hypervelocity impacts at 5 km s(-1) on compact CO2 ice. We have examinated crater morphology (depth, diameter, shape and volume) for impacts by stainless steel projectiles of diameter from 0.4 mm to 2 mm. Relationships between crater and projectile parameters have been derived and extrapolation to other projectile sizes is considered By means of comparison of these results to impacts on H2O ice as presented in the literature, we discuss the influence of icy target material on impact crater records in the Solar System.
