Dr. Deborah Dominique Lorin is a planetary scientist who has worked on many mission operations. The mission of her and her fellow scientists is to learn more about the origin of Earth and the surrounding planets, as well as finding life beyond school. Planetary scientists use geology, biology, chemistry and physics to analyze data about other planets. They also utilize photometry to determine texture and quality of planets. During the seminar Lorin shared about a project she took part of examining the Allan Hills 84001 meteorite that broke from Mars. When analyzing the meteorite, they found what could have been a fossil of bacteria which indicates a possibility of life on Mars. She also taught us about space weathering from the Sun’s solar winds that contain high amounts of radiation. Lorin also explained that mercury has a metal, moving core that produces a magnetic field similar to the Earth.
