CSA Astronaut Jeremy Hansen Sets Out for Geology Field Training in the High Arctic

2013-07-19 - Jeremy Hansen via Twitter on July 19 - Crater geologist gold! A smile emerges on @drcrater's (Dr. Gordon Osinski) face when we find these. Shatter cones! Only find these two places on Earth: nuclear blast sites and meteor craters. High energy from impact shatters the rocks. It is the very distinct ripples that remind me of a seashell.

From July 16 to 25, 2013, Canadian Space Agency Astronaut Jeremy Hansen is in the High Arctic to learn methods and techniques for conducting geological fieldwork that could be applied during future missions to the Moon or an asteroid. Hansen is accompanying Western University's Dr. Osinski and his team from the Centre for Planetary Science and Exploration as they study the Haughton impact crater on Devon Island, Nunavut.
