A series of cratering and catastrophic fragmentation experiments has been performed, involving the impact of aluminum and stainless-steel spheres into warm (about 298 K) and cold (about 100 K) granodiorite targets. Although some vague hints of a thermal effect might be found in some of the results, in no case was there a substantial difference between the warm and cold series. Since these experiments were well within the strength-dominated regime of impact phenomena, variations due to low target temperatures in more energetic events will probably be negligible. Thus, there appear to be no significant temperature-dependent mechanical effects during impact into solid rock over a wide range of temperatures prevalent in the solar system.
