Episode 51 is out today with guest Dr Cassandra Marion! A life-long explorer and outdoorswoman, Cassandra completed her PhD in geology and planetary science and exploration from the Institute for Earth and Space Exploration at Western University where she studied meteorite impact craters in the Canadian Arctic. She also has considerable analogue mission experience, which are simulated robotic and human missions designed to learn, train and prepare for real missions to the Moon and Mars. In her most recent expedition, she helped to train two astronauts in field geology in preparation for upcoming missions to the Moon. In her current role as Science Advisor for the Canada Aviation and Space Museum in Ottawa, Cassandra is dedicated to sharing her passion and knowledge of Earth and planetary sciences with communities near and far as well as acting as liaison and collaborator between the museum, academia, industry and government to connect the greater community of science and technology.  Dr Marion can be found on twitter @planetarycass.
