摘要

Initiated as part of the 2010 Spin Your Thesis campaign, a new ESA Education programme, a group from theUniversity of Glasgow Space Advanced Research Team successfully conducted a series of impact crateringexperiments under a highly accelerated reference frame. This aimed to: reproduce and define the physical conditionsof large-scale cratering events onto highly porous asteroids; provide cratering response data for the validation andadvancement of numerical models; and support the generation of a reliable scaling theory for cratering events.Impact cratering is a fundamental process that has shaped and continues to shape the formation and evolution of oursolar system and other planetary systems. Although much is known on the impact dynamics of rocky, brittle bodies,such as asteroids, little is known on the physical response of highly porous bodies. Consequently the physicalresponse of porous bodies can not be compared to conventional models. Therefore throughout the experimentcampaign, variation into the target material's porosity and projectile density was examined. All in-situmeasurements were recorded relative to the crater's morphological profile and ejecta distribution. This occurredunder increasing levels of acceleration, thereby validating that the experiment occurred within the crater dominatedgravity regime. This paper details the programmatics issues of the initiative, experiences and lessons learnt from thestudent perspective. From its initial proof-of-concept the Spin Your Thesis campaign provided a solid foundationfrom the development of an experimental idea, enabling high scientific return and personal development.
