Friday August 7:

HESA's Mars Express Mission - Hi-Res and “Perspective” Imaging of Mars : Erosion & Deposition The European Space Agency has placed a treasure trove of high resolution images from its Mars Express Mission in the public domain. With optical resolutions in the range of 10-30m per pixel, these images contain astounding detail and have been rendered in oblique perspective, giving the viewer the firm impression of “being there”. As part of an on-going mini-series of three presentations, Simon Hanmer has already talked to us about images from this archive related to martian Topography in general. In this talk, he will present and comment on hi-resolution ESA images that illustrate processes associated with Erosion & Deposition on the martian surface.

Friday September 4:

1. Historical Figures in Astronomy

When many people think of Gerard Kuiper (1905-1973), the Kuiper belt immediately comes to mind. This region, far out in our solar system, containing 100s of thousands of small bodies composed of volatile. Its existence was hypothesized by Kuiper well before its discovery in 1992. But Gerard Kuiper is much more than the Kuiper belt. He lived a fascinating life. Here to tell his story is Carmen Rush, widely known in the Ottawa RASC for her well-researched and riveting account of historical figures in astronomy.

2. 2015 - A Canadian Crater Odyssey by Chuck O'Dale.

Geologists claim that there are over 300 undiscovered meteorite impact craters on Earth. On a recent trip across Canada Gillian and I passed by many of these impact craters. We hope to give you an impression on how many times that we have been blasted from outer space in the past.
