Alexander sent us this video record of his Skype chat on 5 August, conducted as part of the Mars Society's 2012 convention and held just prior to Curiosity's touch down on the Red Planet. Alex wrote:
It was a pleasure, privilege and honour to have spoken by means of a pre-recorded interview to the Mars Society's 2012 Convention on Sunday night about my experiences at Concordia – on the eve of the historic and successful (audacious) landing on the surface of Mars.
I have provided a copy of the pre-recorded interview here - I hope you enjoy it!
