Dr. Angela Stickle is a planetary geologist specializing in hypervelocity impact processes and dynamic failure of materials. She is a co-investigator on the Lunar Reconnaissance Orbiter’s Mini-RF radar and LAMP UV spectrometer, a co-investigator on the Dragonfly mission, a team member on Europa Clipper’s Europa Imaging System (EIS), the lead for the Double Asteroid Redirection Test (DART) mission’s Impact Modeling Working Group, and a member of the Steering Committee and Investigation Team for the AIDA international collaboration. She also studies phenomenology following hypervelocity impacts into a variety of materials and is a member of the NASA NEO Action Plan Modeling Working Group. Dr. Stickle’s main research interests include dynamic properties and failure/fragmentation mechanisms of brittle materials, impact cratering on planetary surfaces, planetary surface evolution, lunar lighting analysis for mission planning, modeling impact signature phenomenology and planetary defense. Her research utilizes experimental facilities such as the NASA Ames Vertical Gun Range, the APL Planetary Impact Lab and the Hopkins Extreme Materials Institute’s Kolsky bar facility; numerical models using the CTH hydrocode; and analysis of planetary spacecraft data.
