October 2011, I attended the 62nd International Astronautical Congress in Cape Town, South Africa. There were in total of 8 plenary events during the congress and I was one of the panelists of the Plenary Event 6 - Next Generation Visions for Earth Observation in 21st Century. You can watch it here. If you wanna see the other plenary events from the congress, you can visit iafastro's channel on Youtube.
