How do the surfaces of different planets change through time? To understand forces that alter planets, scientists often need to explore some of the most remote places on Earth. Hear from Dr. Andrew Johnstone from the Adler Planetarium in Chicago, and learn how scientists perform survey work in arid deserts to investigate processes that modify hills, valleys and other features on worlds like Mars. This often requires careful planning, tenacity, advanced technology and some good luck. See how precise topographic surveys and surface-penetrating radar tell us about lava flows, movement of sand dunes, buried ancient rivers and climate changes on Earth and Mars, leading to better understanding of the changing face of both worlds.
This presentation will take guests on a virtual journey to experience the landscapes of Mars and other worlds using new open-source software called OpenSpace. You can learn more about OpenSpace by visiting openspaceproject.com.
Science Saturdays is a series of lectures and demonstrations that are held on the first Saturday of each month in the SECU Daily Planet Theater at 2:30pm. The presentations are meant to demonstrate the vast variety of careers in scientific fields from astronomy to zoology and are most appropriate for ages 8 and older. Meet a scientist, learn about current research and ask your questions!
Dr. Andrew Johnston, Vice President of Astronomy and Collections at the Adler Planetarium in Chicago, Illinois
Science Saturdays are held in partnership with the NC State Biomedical Engineering Department.
